My 5i5RYH is connected to an LG TV and I always have to turn on the TV before the NUC otherwise I get a similar effect. But that is no big deal for me.

Hello Tony.Su,

 

 

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.

 

 

 

Regards,

I believe the issue has been solved by using a more expensive HDMI cable.
