This conversation has been merged. Please reference the main conversation: Lightroom: My images are in Lightroom but they are all grey. Why?
since yesterday after doing all the update work starting with the graphics Driver to solve GPU deactivated issue I'm done now BUT thumbnails and secondary preview window are Grey respectivly black. And YES Grafics Driver is higher than 374 actually 377.11
Im using three Screens Primary is the Dell built in showing the Problem. Secondary is an EIZO CS240 via Displayport showing also the issue and tertiary is an old ACER AL1951 conneted by HDMI here everything works fine. Prior to all the updates it worked fine on all Screens just the GPU issue was killing my nerves. Also disconnecting addtional Screens does not cure the Problem. I'm out of ideas now looking for help.
