when connected with HDMI 2.0, After wake up, in 80% possibility, if not always, the screen was ruined with the below snapshot. after turn off and on the monitor, i can get the correct screen.
when connected with the Thunderbolt3 2 HDMI converter, it has no problem.
Bad screen just after wake up
Good screen after turn off and then on the monitor
I understand that the display shows blurred when waking the system up from sleep.
First, To better assist you with your request, I will need to check some information about your computer. Please follow these steps:
1. In the keyboard, press WinLogo key + R.
2. In the Run box please type dxdiag and hit Enter.
3. Click on Save All Information (save it in your desktop).
4. Attach the report to this thread.
Also, something that can be tried in a situation like this for testing purposes is to use a different HDMI cable if available, as well as trying to connect the system to a different Monitor/TV and try to replicate the issue, see if it does show blurry.
Let me know the information and your findings.
