I purchased a new Hanspree monitor from Best Buy yesterday, $259 special, 24.6" LCD 1920x1080 resolution, and spent some time before I could get it to work at full resolution. But with help from this forum and others I prevailed. The final setup:
Ubuntu 8.04 Hardy Heron
Radeon 9600 graphics card (old but not ancient), DVI output jack
GPL ati driver
The three last changes between doesn't work and success were:
1. Changed from the proprietery flgrx driver to the ati one
2. Added "virtual 1920 1080" to the display subsection, based on a post that said one may lose resolutions due to memory + overly large defaults
3. Added the lines below to my xorg.conf, which came from get-edid. Note that the get-edid program complains that the EDID file it is reading does not look right and is 'likely invalid'.
Which of the 3 was responsible for success I don't know, but thought that the xorg file might be useful to others. The only glitch wrt to the 19" CRT it replaces is that the screen is blank during bootup, i.e., I see the grub messages, but then nothing more until the login screen.
I had no success using any of the point&click tools; had to fix up /etc/X11/xorg.conf and reboot.
After turning the brightness down to 60 (default was 100) I am quite pleased with the image quality.
