Is there a way to force X to start at 1920x1080?
Using Puppy precise 5.5
I have a 1920x1080 HDTV which I can connect to my PC through the VGA connector. If I boot with the TV then X starts at 1024x768. If I start xorgwizard then it says the TV can not be scanned and asks me to choose a resolution but then starts at 1024x768 whatever I choose.
The TV's manual says to set the resolution on the PC before connecting to the TV. I can set 1440x900 (the maximum on my old monitor) and that's usable on the TV but it's the wrong ratio. If I restart X then it reverts to 1024x768. If I manually change the resolution in xorg.conf to 1920x1080 (or anything else) then X starts at 1024x768 and sometimes changes the value in xorg.conf!
Is there a way to force X to start at 1920x1080? The TV's manual lists supported resolutions but for the frequency it gives only 60Hz sometimes followed by A or B. What would I set for the frequencies for X? Last edited by zygo on Sat 27 Apr 2013, 09:39; edited 1 time in total

I have a newer nvidia pci-express card with DVI , HDMI and VGA out .
Have not had the chance to attach any HDMI screen .
What i know is that with the default kernel and xorg drivers the ddcprobe command only works on the
lowest out ( DVI ) in my case . ddcprobe scans for possible resolutions, and these are offered in xorgwizard .
I don't know anything about RGB out .
My older 1280x1024 monitor needed to press a button to switch VGA and DVI . DVI is not worth it in my experience .
