Monitor won't detect proper resolution

[zintinio]

This has been happening with the majority of screens I try to plug into, but the proprietary nvidia driver never detects the correct resolutions -__- the open-source driver works perfectly with a little xrandr magic, but I'd like to have some 3D acceleration going on. I'm using the desktop version of Nvidia ION and ubuntu 10.10, with the current nvidia driver (from the repositories). The native resolution is 1440x900 @60 Hz. Any thoughts on this? Again, the nouveau driver is great but I'd like to have VDPAU and the like working.

you havent installed new drivers for your card recently have you?

[zintinio]

Just today actually.

Xorg.0.log stats it cannot gather an edid. This information is provided by your monitor upon probe and lists the resolutions/frequencies hardware specs etc.

Solution, gather an edid.bin from a configuration where the monitor is working properly and use this file with the "customEDID" option in your xorg.conf.

I see you're trying to use custom metamodes the Xorg.0.log is saying it doesn't like them. You could try a modeline in place of an edid, I've never tried metamodes before.

Maybe someone can inform us as to how to gather an edid.bin in linux when the nouveau driver is being used.

[VonSpyder]

yeah I did that once with my ATI card and had this same thing happen.

Try setting a different driver if one is available. hopefully one of them will work. If not youll have to do what I did to fix the problem...

[zintinio]

Xorg.0.log stats it cannot gather an edid. This information is provided by your monitor upon probe and lists the resolutions/frequencies hardware specs etc.

Solution, gather an edid.bin from a configuration where the monitor is working properly and use this file with the "customEDID" option in your xorg.conf.

I see you're trying to use custom metamodes the Xorg.0.log is saying it doesn't like them. You could try a modeline in place of an edid, I've never tried metamodes before.

Well, I'll try that actually. I have windows 7 on a small partition, although I rarely use it. I'd still like to find a linux solution for this however. The only problem is that now most of the monitors I use have problems with the driver. As I said, nouveau always works fine, it's the proprietary driver that gets me into this mess >.<

[BicyclerBoy]

I don't know how to use the windows registry data hex.

You could try specify the modes directly without EDID/DDC file by adding
(in the appropriate screen section of xorg.conf)


Option "ModeValidation" "AllowInterlacedModes"
Option "UseEDID" "FALSE"
Option "UseDisplayDevice" "CRT-0"


metamodes should look like this, no @ symbol AFAIK
(in the screen section of xorg.conf)


Option "metamodes" "CRT:1920x1080i60 +0+0; CRT:2048x1152i50 +0+0; CRT:1280x720p60 +0+0; CRT:1024x576p50 +0+0; CRT:848x480p60 +0+0"

[BicyclerBoy]

To read the DDC EDID I2C eeprom from display over VGA or DVI:

for *******/shell there is:

get-edid.exe
parse-edid.exe

for ******* gui:
winI2C DDC lite used it many years ago..

These could output a usable file format..

[zintinio]

metamodes should look like this, no @ symbol AFAIK
(in the screen section of xorg.conf)


Option "metamodes" "CRT:1920x1080i60 +0+0; CRT:2048x1152i50 +0+0; CRT:1280x720p60 +0+0; CRT:1024x576p50 +0+0; CRT:848x480p60 +0+0"

The @ in the code was an attempt to change my panning resolution.

[tjones00]

If your monitor has a VGA connection you can attempt to use it with the VGA then run nvidia-settings and get a working edid.bin from there. This worked for some people with corrupt edid.

Post # 10, #12 in this thread. When they mention Nvidia X Server Settings that's nvidia-settings.

http://ubuntuforums.org/showthread.php?t=883938


I'm still interested in a way of getting a working edid.bin in linux while using nouveau since it seems a lot of people are having edid/resolution issues lately.

[zintinio]

It IS connected over VGA

[tjones00]

Do you have an alternate connection you could try? (DVI/HDMI)

Random googles for me still haven't found a way to gather an edid in linux without using the nvidia driver and nvidia-settings/xconfig.

Maybe there is a way to gather it with xrandr while using the nouveau driver?

This thread might be of interest.

http://forums.opensuse.org/english/get-technical-help-here/hardware/443968-graphics-issue-w-11-2-nvidia-unable-get-full-resolution-1680x1050.html

Although they resorted to finding an edid.bin online.

I think tinkering with the following in nvidia-xconfig might be worth a shot.


-E FILE, --extract-edids-from-file=FILE
Extract any raw EDID byte blocks contained in the specified X log file
LOG; raw EDID bytes are printed by the NVIDIA X driver to the X log as
hexidecimal when verbose logging is enabled with the "-logverbose 6" X
server commandline option. Any extracted EDIDs are then written as
binary data to individual files. These files can later be used by the
NVIDIA X driver through the "CustomEDID" X configuration option.Maybe there is a way to make nouveau behave the same in the Xorg.0.log with the -logverbose 6 X server commandline option then you could try using that Xorg.0.log to generate a edid.bin with nvidia-xconfig.


nvidia-xconfig -A (advanced help)




nvidia-xconfig: version 260.19.06 (buildmeister@builder101) Mon Sep 13
07:06:38 PDT 2010
The NVIDIA X Configuration Tool.

This program is used to manipulate X configuration files, specifically to
enable NVIDIA X driver functionality.

Copyright (C) 2005 - 2010 NVIDIA Corporation.


In its normal operation, nvidia-xconfig finds the system X configuration file
(or generates a new X configuration if it cannot find the system file), makes
sure the configuration is usable by the NVIDIA X driver, applies any updates
requested on the commandline, and writes the new configuration to file.

Please see the NVIDIA README for a description of NVIDIA X configuration file
options.

nvidia-xconfig [options]

-c XCONFIG, --xconfig=XCONFIG
Use XCONFIG as the input X config file; if this option is not specified,
then the same search path used by the X server will be used to find the X
configuration file.

-o OUTPUT-XCONFIG, --output-xconfig=OUTPUT-XCONFIG
Use OUTPUT-XCONFIG as the output X configuration file; if this option is
not specified, then the input X configuration filename will also be used
as the output X configuration filename.

-s, --silent
Run silently; no messages will be printed to stdout, except for warning
and error messages to stderr.

-t, --tree
Read the X configuration file, print to stdout the X configuration data
in a tree format, and exit.

-v, --version
Print the nvidia-xconfig version and exit.

-h, --help
Print usage information for the common commandline options and exit.

-A, --advanced-help
Print usage information for the common commandline options as well as the
advanced options, and then exit.

--acpid-socket-path=ACPID-SOCKET-PATH, --no-acpid-socket-path
Set this option to specify an alternate path to the Linux ACPI daemon
(acpid)'s socket, which the NVIDIA X driver will use to connect to
acpid.

--add-argb-glx-visuals, --no-add-argb-glx-visuals
Enables or disables support for OpenGL rendering into 32-bit ARGB windows
and pixmaps.

--allow-glx-with-composite, --no-allow-glx-with-composite
Enable or disable the "AllowGLXWithComposite" X configuration option.

--bandwidth-test, --no-bandwidth-test
Disable or enable the "NoBandWidthTest" X configuration option.

--busid=BUSID, --no-busid
This option writes the specified BusID to the device section of the X
configuration file. If there are multiple device sections, then it adds
the BusID field to each of them. To add the BusID to only a specific
device or screen section, use the '--device' or '--screen' options.

--preserve-busid, --no-preserve-busid
By default, nvidia-xconfig preserves the existing BusID in the X
configuration file only if there are multiple X screens configured for
the X server. Use '--preserve-busid' or '--no-preserve-busid' to force
the BusID to be preserved or not preserved, overriding the default
behavior.

--cool-bits=COOL-BITS, --no-cool-bits
Enable or disable the "Coolbits" X configuration option. Setting this
option will enable support in the NV-CONTROL X extension for manipulating
GPU clock and GPU fan control settings. Default value is 0. For fan
control set it to 4. WARNING: this may cause system damage and void
warranties.

--composite, --no-composite
Enable or disable the "Composite" X extension.

--connected-monitor=CONNECTED-MONITOR, --no-connected-monitor
Enable or disable the "ConnectedMonitor" X configuration option; setting
this option forces the X driver to behave as if the specified display
devices are connected to the GPU.

--connect-to-acpid, --no-connect-to-acpid
Enable or disable the "ConnectToAcpid" X configuration option. If this
option is set, the NVIDIA X driver will attempt to connect to the Linux
ACPI daemon (acpid). Set this option to off to prevent the X driver from
attempting to connect to acpid.

--constant-dpi, --no-constant-dpi
Enable or disable the "ConstantDPI" X configuration option, which
controls whether the NVIDIA X driver maintains a constant dots per inch
(DPI) value by recomputing the reported size in millimeters of the X
screen when XRandR changes the size in pixels of the X screen.

--custom-edid=CUSTOM-EDID, --no-custom-edid
Enable or disable the "CustomEDID" X configuration option; setting this
option forces the X driver to use the EDID specified.This option is a
semicolon-separated list of pairs of display device names and filename
pairs; e.g "CRT-0:\tmp\edid.bin". Note that a display device name must
always be specified even if only one EDID is specified.

--dac-8bit, --no-dac-8bit
Most Quadro parts by default use a 10 bit color look up table (LUT) by
default; setting this option to TRUE forces these graphics chips to use
an 8 bit (LUT).

-d DEPTH, --depth=DEPTH
Set the default depth to DEPTH; valid values for DEPTH are 8, 15, 16, 24,
and 30.

--device=DEVICE
The nvidia-xconfig utility operates on one or more devices in the X
configuration file. If this option is specified, the device named DEVICE
in the X configuration file will be used. If this option is not
specified, all the devices within the X configuration file will be used.

--disable-glx-root-clipping, --no-disable-glx-root-clipping
Disable or enable clipping OpenGL rendering to the root window via the
"DisableGLXRootClipping" X configuration option.

--damage-events, --no-damage-events
Use OS-level events to notify the X server when a direct-rendering client
has performed rendering that needs to be composited to the screen.
Improves performance when using GLX with the composite extension.

--dynamic-twinview, --no-dynamic-twinview
Enable or disable support for dynamically configuring TwinView.

--preserve-driver-name
By default nvidia-xconfig changes the display driver to "nvidia" for
all configured X screens; this option preserves the existing driver name
of each X screen.

--enable-acpi-hotkeys, --no-enable-acpi-hotkeys
The "EnableACPIHotkeys" option can be specified to override the NVIDIA X
driver's default decision to enable or disable ACPI display change hotkey
events.

-a, --enable-all-gpus
Configure an X screen on every GPU in the system.

--exact-mode-timings-dvi, --no-exact-mode-timings-dvi
Forces the initialization of the X server with the exact timings
specified in the ModeLine.

-E FILE, --extract-edids-from-file=FILE
Extract any raw EDID byte blocks contained in the specified X log file
LOG; raw EDID bytes are printed by the NVIDIA X driver to the X log as
hexidecimal when verbose logging is enabled with the "-logverbose 6" X
server commandline option. Any extracted EDIDs are then written as
binary data to individual files. These files can later be used by the
NVIDIA X driver through the "CustomEDID" X configuration option.

--extract-edids-output-file=FILENAME
When the '--extract-edids-from-file' option is used, nvidia-xconfig
writes any extracted EDID to a file, typically "edid.bin" in the current
directory. Use this option to specify an alternate filename. Note that
nvidia-xconfig, if necessary, will append a unique number to the EDID
filename, to avoid overwriting existing files (e.g., "edid.bin.1" if
"edid.bin" already exists).

--flatpanel-properties=FLATPANEL-PROPERTIES, --no-flatpanel-properties
Set the flat panel properties. The supported properties are: 'scaling',
'dithering' & 'ditheringmode'. Please see the NVIDIA README 'Appendix B.
X Config Options' for more details on the possible values and syntax.

--flip, --no-flip
Enable or disable OpenGL flipping

--force-generate
Force generation of a new X config file, ignoring any existing system X
config file. This is not typically recommended, as things like the mouse
protocol, keyboard layout, font paths, etc, are setup by your Unix
distribution. While nvidia-xconfig can attempt to infer these values, it
is best to use your Unix distribution's X config file for the basis of
anything that nvidia-xconfig creates.

--force-stereo-flipping, --no-force-stereo-flipping
Normally, stereo flipping is only performed when a stereo drawable is
visible. This option forces stereo flipping even when no stereo drawables
are visible.

--handle-special-keys=WHEN, --no-handle-special-keys
Specify when the X server should use the builtin keyboard handler to
process special key combinations (such as Ctrl+Alt+Backspace); see the X
configuration man page for details. The value of WHEN can be 'Always',
'Never', or 'WhenNeeded'.

--include-implicit-metamodes, --no-include-implicit-metamodes
Enable or disable the "IncludeImplicitMetaModes" X configuration option.

--keyboard=KEYBOARD
When generating a new X configuration file (which happens when no system
X configuration file can be found, or the '--force-generate' option is
specified), use KEYBOARD as the keyboard type, rather than attempting to
probe the system for the keyboard type. For a list of possible keyboard
types, see the '--keyboard-list' option.

--keyboard-driver=DRIVER
In most cases nvidia-xconfig can automatically determine the correct
keyboard driver to use (either 'kbd' or 'keyboard'). Use this option to
override what nvidia-xconfig detects. Typically, if you are using an
X.Org X server, use 'kdb'; if you are using an XFree86 X server, use
'keyboard'.

--keyboard-list
Print to stdout the available keyboard types recognized by the
'--keyboard' option, and then exit.

--layout=LAYOUT
The nvidia-xconfig utility operates on a Server Layout within the X
configuration file. If this option is specified, the layout named LAYOUT
in the X configuration file will be used. If this option is not
specified, the first Server Layout in the X configuration file is used.

--logo, --no-logo
Disable or enable the "NoLogo" X configuration option.

--logo-path=PATH, --no-logo-path
Set the path to the PNG file to be used as the logo splash screen at X
server startup.

--mode=MODE
Add the specified mode to the mode list.

--mode-debug, --no-mode-debug
Enable or disable the "ModeDebug" X configuration option; when enabled,
this option causes the X driver to print verbose details about mode
validation to the X log file.

--mode-list=MODELIST
Remove all existing modes from the X configuration's modelist and add the
one(s) specified in the MODELIST string.

--remove-mode=MODE
Remove the specified mode from the mode list.

--metamodes=METAMODES
Add the MetaMode X configuration option with the value METAMODES which
will replace any existing MetaMode option already in the X configuration
file.

--mouse=MOUSE
When generating a new X configuration file (which happens when no system
X configuration file can be found, or the '--force-generate' option is
specified), use MOUSE as the mouse type, rather than attempting to probe
the system for the mouse type. For a list of possible mouse types, see
the '--mouse-list' option.

--mouse-list
Print to stdout the available mouse types recognized by the '--mouse'
option, and then exit.

--multigpu=MULTIGPU, --no-multigpu
Enable or disable MultiGPU. Valid values for MULTIGPU are 'Off', 'On',
'Auto', 'AFR', 'SFR', 'AA'.

--multisample-compatibility, --no-multisample-compatibility
Enable or disable the use of separate front and back multisample
buffers.

--nvagp=NVAGP, --no-nvagp
Set the NvAGP X config option value. Possible values are 0 (no AGP), 1
(NVIDIA's AGP), 2 (AGPGART), 3 (try AGPGART, then try NVIDIA's AGP);
these values can also be specified as 'none', 'nvagp', 'agpgart', or
'any'.

--nvidia-cfg-path=PATH
The nvidia-cfg library is used to communicate with the NVIDIA kernel
module to query basic properties of every GPU in the system. This
library is typically only used by nvidia-xconfig when configuring
multiple X screens. This option tells nvidia-xconfig where to look for
this library (in case it cannot find it on its own). This option should
normally not be needed.

--only-one-x-screen
Disable all but one X screen.

--overlay, --no-overlay
Enable or disable the "Overlay" X configuration option.

--cioverlay, --no-cioverlay
Enable or disable the color index overlay.

--overlay-default-visual, --no-overlay-default-visual
Enable or disable the "OverlayDefaultVisual" X configuration option.

--transparent-index=INDEX, --no-transparent-index
Pixel to use as transparent when using color index overlays. Valid
values for TRANSPARENT-INDEX are 0-255.

-T, --post-tree
Like the '--tree' option, but goes through the full process of applying
any user requested updates to the X configuration, before printing the
final configuration to stdout in a tree format. Effectively, this option
just causes the configuration to be printed to stdout as a tree instead
of writing the results to file.

--power-connector-check, --no-power-connector-check
Disable or enable the "NoPowerConnectorCheck" X configuration option.

--probe-all-gpus, --no-probe-all-gpus
Disable or enable the "ProbeAllGpus" X configuration option.

--query-gpu-info
Print information about all recognized NVIDIA GPUs in the system.

--randr-rotation, --no-randr-rotation
Enable or disable the "RandRRotation" X configuration option.

Enable or disable the "RenderAccel" X configuration option.

--render-extension, --no-render-extension
Disable or enable the "NoRenderExtension" X configuration option.

--rotate=ROTATE, --no-rotate
Enable or disable the "Rotate" X configuration option. Valid values for
ROTATE are 'normal', 'left', 'CCW', 'inverted', 'right', and 'CW'.
Rotation can be disabled

--screen=SCREEN
The nvidia-xconfig utility operates on one or more screens within a
Server Layout in the X configuration file. If this option is specified,
the screen named SCREEN in the X configuration file will be used. If
this option is not specified, all screens within the selected Server
Layout in the X configuration file will be used used.

--separate-x-screens, --no-separate-x-screens
A GPU that supports multiple simultaneous display devices can either
drive these display devices in TwinView, or as separate X screens. When
the '--separate-x-screens' option is specified, each GPU on which an X
screen is currently configured will be updated to have two X screens
configured. The '--no-separate-x-screens' option will remove the second
configured X screen on each GPU. Please see the NVIDIA README
description of "Separate X Screens on One GPU" for further details.

--sli=SLI, --no-sli
Enable or disable SLI. Valid values for SLI are 'Off', 'On', 'Auto',
'AFR', 'SFR', 'AA', 'AFRofAA', 'Mosaic'.

--stereo=STEREO, --no-stereo
Enable or disable the stereo mode. Valid values for STEREO are: 0
(Disabled), 1 (DDC glasses), 2 (Blueline glasses), 3 (Onboard stereo), 4
(TwinView clone mode stereo), 5 (SeeReal digital flat panel), 6 (Sharp3D
digital flat panel), 7 (Arisawa/Hyundai/Zalman/Pavione/Miracube), 8 (3D
DLP), 9 (3D DLP INV), 10 (NVIDIA 3D VISION).

--thermal-configuration-check, --no-thermal-configuration-check
Disable or enable the "ThermalConfigurationCheck" X configuration
option.

"HD480p", "HD720p", "HD1080i", "HD1080p", "HD576i", "HD576p".

--tv-out-format=TV-OUT-FORMAT, --no-tv-out-format
Enable or disable the "TVOutFormat" X configuration option. Valid values
for "TVOutFormat" are: "SVIDEO" and "COMPOSITE".

--tv-over-scan=TV-OVER-SCAN, --no-tv-over-scan
Enable or disable the "TVOverScan" X configuration option. Valid values
are decimal values in the range 1.0 and 0.0.

--twinview, --no-twinview
Enable or disable TwinView.

--twinview-orientation=ORIENTATION, --no-twinview-orientation
Specify the TwinViewOrientation. Valid values for ORIENTATION are:
"RightOf" (the default), "LeftOf", "Above", "Below", or "Clone".

--twinview-xinerama-info, --no-twinview-xinerama-info
Prohibits providing Xinerama information when in TwinView.

--twinview-xinerama-info-order=TWINVIEW-XINERAMA-INFO-ORDER,
--no-twinview-xinerama-info-order
Enable or disable the "TwinViewXineramaInfoOrder" X configuration option.
TWINVIEW-XINERAMA-INFO-ORDER is a comma-separated list of display device
names that describe the order in which TwinViewXineramaInfo should be
reported. E.g., "CRT, DFP, TV".

--ubb, --no-ubb
Enable or disable the "UBB" X configuration option.

--use-edid, --no-use-edid
Enable or disable use of the EDID (Extended Display Identification Data)
from your display device(s). The EDID will be used for driver operations
such as building lists of available modes, determining valid frequency
ranges, and computing the DPI (Dots Per Inch). This option defaults to
TRUE (the NVIDIA X driver will use the EDID, when available). It is NOT
recommended that you use this option to globally disable use of the EDID;
instead, use '--no-use-edid-freqs' or '--no-use-edid-dpi' to disable
specific uses of the EDID.

--use-edid-dpi, --no-use-edid-dpi
Enable or disable use of the physical size information in the display
device's EDID, if any, to compute the DPI (Dots Per Inch) of the X
screen. This option defaults to TRUE (the NVIDIA X driver uses the
EDID's physical size, when available, to compute the DPI).

--use-edid-freqs, --no-use-edid-freqs
Enable or disable use of the HorizSync and VertRefresh ranges given in a
display device's EDID, if any. EDID provided range information will
override the HorizSync and VertRefresh ranges specified in the Monitor
section. This option defaults to TRUE (the NVIDIA X driver will use
frequency information from the EDID, when available).

--use-int10-module, --no-use-int10-module
Enable use of the X Int10 module to soft-boot all secondary cards, rather
than POSTing the cards through the NVIDIA kernel module.

--use-display-device=DISPLAY-DEVICE, --no-use-display-device
Force the X driver to use the display device specified.

--use-events, --no-use-events
Enable or disable "UseEvents" X configuration option. Setting this option
will enable the X driver to use the system events in some cases when it
is waiting for the hardware. With this option X driver sets an event
handler and waits for the hardware through the poll() system call. This
option defaults to FALSE.

--virtual=WIDTHxHEIGHT, --no-virtual
Specify the virtual screen resolution.

--x-prefix=X-PREFIX
The X installation prefix; the default is /usr/X11R6/. Only under rare
circumstances should this option be needed.

--xinerama, --no-xinerama
Enable or disable Xinerama.

--xvmc-uses-textures, --no-xvmc-uses-textures
Forces XvMC to use the 3D engine for XvMCPutSurface requests rather than
the video overlay.

--color-space=COLORSPACE, --no-color-space
Enable or disable the "ColorSpace" X configuration option. Valid values
for "COLORSPACE" are: "RGB" and "YCbCr444".

--color-range=COLORRANGE, --no-color-range
Sets the "ColorRange" X configuration option. Valid values for
"COLORRANGE" are: "Full" and "Limited".

Ok this might work IF you are using a 32b system. If you are using 64b this won't work.

sudo apt-get install read-edid

Or install read-edid via Synaptic Package Manager.

Installs a package that has two programs get-edid and parse-edid.

man for get-edid/parse-edid



get-edid(1) get-edid(1)
NAME
get-edid, parse-edid - read-edid tools to retrieve and interpret moni‐
tor specifications using the VESA VBE DDC protocol

SYNOPSIS
get-edid | parse-edid
get-edid > filename
parse-edid < filename

DESCRIPTION
The read-edid utility comprises two tools: get-edid and parse-edid.

get-edid uses Linux's vm86(2) system call to enter virtual 8086 mode
and perform Data Display Channel (DDC) transfers using the VESA BIOS
Extensions (VBE) to retrieve information from monitors, including iden‐
tification strings, supported sync ranges, available video modes, and
video mode parameters. Such information is often useful for configur‐
ing X Window System servers such as XFree86.

The data obtained by get-edid is in a binary format, so the parse-edid
command is available to interpret it and generate a human-readable
block of text information that can also be included in an XFree86
XF86Config file.

It is customary to invoke get-edid and parse-edid together in a pipe‐
line.

get-edid and parse-edid accept no options, recognize no environment
variables, read no input files, and create no output files.

AUTHOR
get-edid and parse-edid were written by John Fremlin, Dan Hugo, and
Martin Kavalec, using the LRMI (Linux Real-Mode Interface) library by
Josh Vanderhoof. This manual page was written by Branden Robinson,
originally for Debian GNU/Linux.

First check that get-edid can gather a proper resolution. This should be independent of any active display driver.


sudo get-edid | parse-edid

If that looks fine (parse-edid will display resolutions) you can use get-edid to create an edid.bin binary file.


sudo get-edit > edid.bin

Now use that file with CustomEDID in xorg.conf.


If the results of parse-edid don't look good try uninstalling nvidia and check get-edid | parse-edid with nouveau running and see if it looks any different. If it looks good with nouveau grab the edid.bin with get-edid.

Sounds like a plan. I'll do it later tonight.

Your edid dat can be parsed..
cat edid.text | parse-edid

The errors & output is attached
The EDID data is incomplete, should be way bigger...

This linux forum requires that you use dos file name extensions !


If all else fails..this should work.

If you want to try to stop mode validating against the EDID then :
edit /etc/X11/xorg.conf

Code:

Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "ModeValidation" "NoEdidModes"
Option "ModeValidation" "AllowInterlacedModes"
Option "UseEDID" "FALSE"
Option "UseDisplayDevice" "CRT-0"
Option "TVStandard" "HD1080p"
SubSection "Display"
Depth 24
Modes "HD1080p"
EndSubSection
EndSection

This assumes your TV is 1080p capable..
"HD720p" "HD1080i" are valid built-in TV video modes.

The"DFP-0" may not match the wired ports of your video card, may need "CRT-1".
You may need to try these commands as well:
Option "IgnoreEDID" "True" # not used anymore ?
Option "ConnectedMonitor" "DFP-0" # not recommended as overwrite scan

Please note the attached edid.txt is complete rubbish ..

There is a newer version with i2c support code for newer video cards..

http://www.polypux.org/projects/read-edid/

download read-edid-i2c.tar.gz

Does not work, think need kernel space module i2c interface
