ATI 4850 dual screen

Newbe:
I've a single ATI with dual monitor connections,
as Im using windows 7 and the latest win7 x64 drivers from ati (after installing all drivers in the latest history)


I lose my second screen(screen remains in sleep mode) after the sleep mode initiated . It seems to be a programming error in the driver...


I can get the second screen up by the following sequence simple logging out --->>
switch User ... logging back in ( it takes some time after loggging in though....

Is there a way to detect what sequence(command) is sent to the screen and if I could add that sequence in the loggin...

I've the impression service from ati is bad they've simular reports dating from the beggining of Vista and never bothered to change anyting (by the way never had such problems in XP)



your remarks please

Try drivers directly from ATI for Windows 7. Don't rely on the Microsoft default drivers for your card. Hopefully this will help if you don't already have ATI-supplied drivers.

as noted before did that already ... only allows to use full screen resolution over MS version. but the described problem remains WITH ALL THE LAST ATI DRIVERS (jan-2009 till jul-2009)

Oops, sorry, missed that. Does this occur with the Aero UI disabled (ie: classic theme)?

I hate to say it but this may be something that ATI needs to fix. I know that some video drivers have problems coming out of sleep mode. I experienced problems with my Nvidia similar on a beta driver. The worse part was that it was my primary that didn't light up. So I could never log in, I had to shut it down each time. I would just keep checking back with ATI daily. BTW what card do you have?

I would concur. The only other possible explanation is that your motherboard's BIOS is set to a legacy suspend mode (ie: S1) or is doing something odd when Windows 7 goes into a sleep mode.
