LCD TV as Monitor


I had an old CRT monitor which was not performing fully to my expectations..Suddenly a thought wave and I connected the cabinet to my LG (32") Native Resolution (1340*720 & thereabouts)LCD TV. (connected thru VGA cable as my Board doesnt support HDMI or DVI)

My Board supports NVIdia Geoforce 7025 ..In win , I am able to get a full screen display on selecting NVIDIA Control Panel which allows me to push the screen to the right to cover the black strip.

In Linux Distros however there are varied results

1. Debian/Ubuntu and Variants --- Getting Display but most of the contents in the left (incl menu Icons) gets hidden

2.Pardus /Archbang --- Horizontal flickering stripes appear and I am forced to reboot..

How do I adjust the resolution in such cases? Should I append the kernel for a specified resolution?

I guess it depends on what video driver you are using. If you are using a free driver then you should probably play with xrandr if you are using the driver from nvidia you could try running nvidia-settings.

Its a new computer I have assembled and I am trying to install Linux...Both in my CRT as well as my TV mentioned , the resolution seems to be a problem....I am not at all able to install a distro in the first place as the installer screen is way off and I have to do a lot of guesswork.Also pls have a look at the problems I faced in my CRT...Yet to find a solution....

Do the installation using the CRT, then once you have the system up and running try to configure the LCD.

Your monitor refresh rate and/or resolution is off. I'd guess you arent gettign the EDID values. You can run this-

grep -i edid /var/log/Xorg.0.log

Or you can look through your Xorg.0.log and have a look at stuff around the EDID output.

As for how to fix it...the easiest way would be to install the nvidia drivers, then edit the xorg.conf with correct resolutions/refresh rates for your monitor (or tv).

BTW, you can install onto the HDD with a different machine, then move the HDD over to your new machine. Makes things easier than playing with installer screen you cant see correctly. I wouldnt install the nvidia drivers on a different machine though.
