VGA resolution with Sony Bravia TV

Try a new cable. I've seen so many cases that the PC can't detect the monitor's resolution due to the broken cable. The component signals are still OK so the image can be displayed, but the monitor information which is sent in another wire can't be read properly

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.

Any ideas?

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

  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?

  You might want to update that installation of Ubuntu...

  You think? This question was asked in 2009 when 9.04 was current. Pay attention

I did check that, but I, of course, get no other option then 60hz when plugged into the TV.

On both laptop and PC?

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.

While Windows and Ubuntu do indeed use different video drivers, the rest just isn’t true. Display timings and whatnot are standardized and the signal leaving the VGA/DVI/whatever port is in no way OS-specific.

Daniel, please see the edit for an explanation of the effect different drivers can have. The protocols, though standardized in theory, are not always implemented in the same way.

That’s got nothing to do with the signal that leaves the computer.

I think you are right... It isn't the interaction between the two different drivers but rather that the driver on Windows is the problem and needs to be updated.
