I have the same problem with my 2017 4K Samsung TV, tried 2 different NUCs plus many hdmi cables. Always static after watching Netflix (during or after). Reconnecting hdmi cable usually helps (brings back the desktop). Have not found a solution.
Same issue here. Tried several nuc’s. Celeron version, i7 using 2 different high quality cables (monster hdmi cables) making sure the direction is also correct. Changed the bios settings to hdmi as primary display etc. Nothing works.
When unplugging and plugging it back sometimes I do get the desktop to show. But when restarted it is gone again. Downloaded the intel driver update utility and updated all drivers. Still nothing.
Tested now 3 nuc’s and nothing. Raspberry pi4, Apple Mac Pro, other hdmi devices all work fine.
Frustrating as the nuc’s with i7, 32gb ram and nvme1.3 ssd aren’t cheap. Pi4 is 80 bucks and works without any issues - disappointed in inter at this moment.
