I've just bought a Sony Bravia KDL40S5100 TV. Its 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 desktop 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 original 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.
This laptop also has Win7, which I am going to try, but I haven't gotten a chance yet.
