Screen blank during startup with GTX650

[Alex Bennett]

I have two monitors and I have connected the DVI to my main LG Monitor and the Dsub Analog to my secondary Sharp monitor. The GTX650 was recently installed.

When I boot up the main screen does not detect any signal and stays blank until it suddenly goes blue with the Windows 7 welcome screen. Thereafter all is well. The secondary screen says Windows Starting then goes blank until the Screen saver appears.

 

As a result I do not see any opening BIOS information or which drives have started up. I tried switching the inputs and the BIOS data came up on my main screen and all seemed well, the BIOS information showng. However, I then found that the screen was too large for my monitor and being Analog input instead of the DVi, I was unable to resize the screen as screen sizing is not supported for VGA.

I have now put the original inputs back and so I am back to square one with no screen until the welcome screen appears.

 

I am using Windows 7 Home Premium.

 

Any help would be appreciated.

 

Thanks.

Hi I have a similar set up but with 3 screens , what am thinking is you have disabled show POST during startup this happens before you see the windows logo , I'd check BIOS and in there will be advanced settings if you want to see the POST screen there will be a setting , if you need further help give us a shout
