Fedora 12 Beta: Std monitor OK, HDTV does 800x600 only


Hi folks,

I have been playing with some distros on a backup PC. If I install to an old CRT (which is not presently available for testing), the video is fine. If I install it to my HDTV (VGA connection; more limited in video modes and settings), I must specify "basic video" on the install boot screen, or the TV errors out with "video mode not supported". The install then works, but I am limited to 800x600 or 640x480 in the SYS ==> PREF ==> DISPLAY screen. I only need to get to 1024x768 @ 60hz.

Regards,

OM

Hi OM,

Have you tried specifying the resolution ?

eg. 'linux resolution=1024x768'

cheers

Thanks for the reply, kpb. I tried entering the string you suggested in XORG.CONF. The complete file appears below (including the new line). Not much to it, as you can see. I rebooted, and Fedora would no longer produce any video. I rebooted to Puppy (I think having that will prove to be handy) and changed the file back. Fedora is back up, but the problem of course persists.

Section "Device"
Identifier "Videocard0"
Driver "vesa"
linux resolution=1024x768
EndSection

I was pretty sure you did not intend for the string to be used in this way, but thought I would try it. What method did you intend?

Regards,

OM

Does your TV support this resolution, a 720p TV will only support a vertical resolution of 720 (actual resolution being 1280x720). I would advise checking the technical manual of the TV and seeing if that has a list of supported resolutions for the TV itself.

Sorry mate,

I meant to kick off the install, if you're already up and running it may be better to try r3sistance's suggested resolution

What vid card are you running? .. If nvidia, they have a utility specifically for this 'nvidia-xconfig' I think

<edit>This may help too: http://wilsonet.com/mythtv/mythhd.php</edit>

cheers

Thanks for the continued tips, folks. I get 1024x768 fine with Puppy (funny how the tiny distro works great, but not the major one). I think my XORG.CONF file is telling me I am running VESA instead of XORG? Maybe I just need to load XORG, but I don't know how to do that.

This is very similar to not having a driver loaded in Windows, and you only get 640 or 800, but I did not need a driver for Puppy. I'm running a pretty old card, ATI Radeon 7000.
