I connected my laptop (Windows 8.1) to a boardroom Projector and on completion disconnected by unplugging the cable without closing the presentation. If I now connect to a second monitor, the second screen has a yellow background. I have tried another monitor with the same results - the laptop screen is not affected .
Thanks for joining the Graphics community.
I would need more information in regards to your system configuration:
Which version of Windows do you have? Windows 8.1 x32- or x64-bit?
Also, the exact processor model and the graphics controller:
Click the Windows icon, and then right-click Computer .
Select Properties .
Find System Type on the Properties window, and then note the processor model.
