- Two Samsung SyncMaster SA850 monitors.
- Nvidia GeForce GT 640 graphic card.
- Windows 8 64 bit.
When leaving the office in the evening, I let Windows 8 run (all power saving settings disabled) and only turn off the monitors.
When returning the next morning and turning on both monitors, I'm often (but not always) forced to do the following steps.
First, both monitors are turned on and the image looks like:
(Both monitors on, the left shows no image, the right shows the image stretched too far)
Next, I press the | | button on the right monitor:
Then, this image is shown:
(Both monitors on, the left shows no image, the right shows the image jolted to approx 50% of the real width)
Then, I once more press the | | button on the right monitor and finally get the correct behavior:
(Monitor 1 with log in screen, monitor 2 currently no image but showing desktop after successful log in)
- It doesn't matter which monitor I turn on first or second.
- It doesn't matter into which port of the Nvidia card in plug which monitor.
- The behavior is correct when booting the PC.
My question is:
- Is this most likely an issue of the monitor(s), the graphic card or of Windows 8?
Thanks to Dave's comment, I have to add that I often connect via VPN/RDP to the two monitor PC during the monitors are being turned off.
Maybe this changes the screen resolution and maybe this causes this effect?
