Q45/43 Issue with Dual Monitors and resuming from sleep

[idata]

Hi

I have a desktop with a Q45/Q43 chipset and dual monitors. Everything works fine. However most of the time when I resume from sleep the chipset only sees one monitor. I can fix the problem by either rebooting or reinstalling the driver (half way though the install it detects the other monitor and brings it back to life), either of these is really annoying. I've tried playing with power settings but to no avail...any ideas?

Driver version is 8.15.10.2555 and desktop in running windows 7 professional. Monitors are EIZO M1700 and EIZO L887. Swapping video connections makes no difference its always the one on HDMI cable that fails to wake up

Hi Roger,

Can you provide the following system information for me please?

+ What CPU are you using?

+ What display adapter do you have?

+ Are you running Windows 7 64 or 32 bit?

Thank you,

HI

Thanks for replying. I'm using Windows 7 profesional 32 bit. The CPU is Intel Core 2 Duo E7500 and the graphics card is embedded in the motherboard - it's an HP Compaq Elite 8000 SFF Business PC

I would recommend updating your BIOS, and possibly switching back to the OEM provided/supported GFX drivers (8.15.10.2302 according to HP's website). The link below has the download for your BIOS update and GFX driver update.

Go ahead and give those a try, and let me know if this fixes the issue or not.

Thanks,

Hi

New drivers and new BIOS had no effect. In the end I have had to turn power saving sleep mode off via group policy and so it never turns the monitors off and I no longer see the problem

Thanks for your help anyway
