Screen flicker comes back to my NUC 7i5BN HDMI @4K 60Hz.
It was happened long time ago and was solved by graphic driver update. But Now screen flickers come back with new driver update, and will not go out even with I downgrade graphic driver.
Hope Intel can pay attention to this problem!
Thanks and Regards!
So, I think you are incorrectly using the description 'flicker'. You are seeing the monitor reset its image (and go blank for a second or so) on some regular basis, right?
The best answer I can give for this issue is for you to purchase a better quality dongle (if using USB-C connector) and/or better quality HDMI cable. And, before you say anything, it doesn't matter how well this cable (etc.) might work on some other PC, you need a better quality one for the NUC. More than 90% of similarly-reported issues are fixed with a better cable.
Aside: If you are going to use a 4K monitor with the BN NUCs, you should be using the USB-C connector and a USB-C to DisplayPort or USB-C to HDMI (one saying it supports 4K at 60Hz) dongle to connect to the monitor.
Hope this helps,
