I just bought Sony Bravia KDL40S5100 tv. The VGA input is acting weird. I have a Gateway desktop with Windows 7 and Intel 945 graphics. I also have a laptop running Ubuntu 9.04.

The TV will not display the gateway when the resolution is over 1360x768, I have to wait for it to time out and bring me back. The Intel driver even urges me to switch to the "recommended" 1920x1080. I just installed Win7 using this tv as the monitor. When the orginial welcome screen started after setup, it started me at 1080. I had to start in safemode to set a res that would work!

When I plug my laptop into the TV, 1920x1080 works just fine.

Any ideas?

This laptop also has Win7, which I am going to try, but I haven't gotten a chance yet.

Are both the TV and laptop connecting over VGA? –  William Hilsum Aug 29 '09 at 15:32
    
Yeah, VGA is the only interface I'm using out of these PC's. I still haven't figured it out, but I haven' spent much time with it. –  prestomation Aug 29 '09 at 18:32

Some TVs are very picky about the signal quality and timing over VGA. 1080 over VGA is pushing the boundaries over cheap VGA cabling. Have you tried a short cable? –  Brad May 5 '12 at 20:20

Sounds like it could be a refresh rate out of range (as far as the TV is concerned) -- have you compared the rates between PC and Laptop?

I did check that, but I, of course, get no other option then 60hz when plugged into the TV. –  prestomation Aug 15 '09 at 15:53
    
On both laptop and PC? –  Rowland Shaw Aug 15 '09 at 16:27
    
Are you setting the resolution from the standard Win7 display dialog, or through the Intel GFX application? I have an old Acer laptop that will not allow me to set a decent resolution through the standard windows dialog, but calling up the Intel GFX settings allows me to do whatever I wish. –  Lee Harrison Sep 19 '12 at 17:55
