U2722DE, flashing, flickering
Hello,
I just want to ask. I'm using U2722DE as primary monitor and ThinkVision as secondary via DP daisy chain. Connected via Baseus USB-C cable from ThinkPad T14 to U2722DE. All is working fine. But at the last time I see that the U2722DE is from time to time flickering, darkens and brightens. In left upper corner I see red message Standard, RGB and vice versa. Where I can search the problem? Cable? But from the beginning I did not face this issue with the used cable. USB-C port in ThinkPad T14? Or some monitor gap with signal resolution?
Thanks for response.
So update. I performed factory reset as described. And the status is: if Im in windows as usual, firefox, opera, outlook, no change... then I switch to PowerPoint and monitor goes and show me in left upper corner sRGB. I switch to Word document I got Standard red message in left upper corner. Back to Adobre reader from Power Point I got Standard, back to PowerPoint sRGB. Its some automatic function for color calibration??

First, simplify the setup. Disconnect the second ThinkVision monitor from the U2722DE. Factory Reset the U2722DE in its Menu- Others. See page 78 in the online U2722DE User's Guide. Then retest the U2722DE by itself to see if the issue happens again.
