How to watch movies on tv from my laptop

[notanerd]

I finally got catalyst 9.3 installed and working. I can set up cloning through Catalyst Control Centre so that I can watch movies on my tv.

But my problem now is that video playback is crappy now. Watching on a small screen is fine but once I go to full screen the playback is choppy lagging. This happens when using VLC and also online with youtube and google videos.

I have googled this error and it seems like i need to edit my xorg.conf file but I don't know what it is that I am meant to change

here is my x.org.conf

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

OK so I have got it to work. I removed fglrx because it was too slow and choppy. But I found some commands that enabled 2 screens to work with the s-video cable. They are as follows

xrandr --output S-video --set load_detection 1
xrandr --addmode S-video 800x600
xrandr --output S-video --mode 800x600

After entering those commands my computer was on my tv. I have to mirror the resolutions in System/Preferences/Screen Resolution if I want to watch movies on the tv, but that is no great hassle. Hopefully this can help some people. Thanks to all those who made suggestions.
