Windows 7 Monitor Problem
 

I have looked all over the net and can't find an answer to this:

I have upgraded from windows Vista ultimate to windows 7 ultimate. The installation went fine.

My pc is connected to my main monitor which is a Sony HDTV via the VGA connection.

My graphics card is ATI HD2400 and the drivers are Vista/windows 7 and upto date.

I right click on my desktop choose screen resolution then detect, it detects my Sony tv and sets the correct resolution I apply and click OK.

Not every time, but, on booting my computer to the desktop windows 7 reverts back to the generic pnp monitor, why????

I then have to repeat the above steps for the correct resolution.

This didn't happen in Vista.

Anyone come across this??

Thanks in advance.

are you using the drivers that came with win7 for your graphics card or did you download from the graphic card or computer (if came with computer) manufacturer?

I built the computer myself so download the drivers from the ati site Dan.
