Hello,
I have a Compaq EVO D51S SFF which I had plugged to my LCD TV as a media centre, just to watch movies and all. I had not connected this computer to the internet because I did not have a wireless card.
I finally installed a wireless card, and then windows started doing all sorts of updates as expected (since the version on the SFF was SP2).
Once windows was done with the updates, I started having problems with the screen resolution. The SFF does not have a stand alone video card, so I had set the resolution at 1024 x 768, and this worked just fine before the updates.
Now, the resolution keeps changing and this is a problem because the LCD TV gives me a message saying "Resolution Not Supported", so I can't use the computer unless I connect it to a regular computer monitor, select 1024x768, and then connect to the TV. I connect via VGA port, not DVI (don't have DVI).
Any suggestions on how to fix this?

First thing I would check is to make sure that all my drivers were current. Not saying this will fix the problem, but it can't hurt. Also, check to see if there might be a driver that supports your particular LCD TV.

The drivers are current. That was the first thing I did, so I got drivers from Intel. I did not help.

Well obviosuly the problem can be through two things:
#1) The rate of refresh on the screen is higher than that of the LCD screen, raise or lower to refresh rates so it can suport the screen
#2) The size of the screen may be the issue as they have different dimensions, instead of changing your computer screen change the output settings its on as it may be needed inorder to be supported to the TV.

Thanks, I think you are correct with your comments. When I turn on the computer, I see the resolution is 600*480 at 60MHz (This is when the windows logo is on the screen). Please note that this is the same as it was before, I would get that resolution and then, once windows loaded, the resolution changed to 1024*768 at 75Mhz, with no problems.

I lowered the refresh rate from 75 to 60, but still got the same result.

Could you please explain how to proceed for item #2) in your reply?
