How do I fix oled tv from going black constantly?


I have connected my NUC NUC7i7BNH to an LG OLED65C8P 65-Inch 4K Ultra HD Smart OLED TV (2018 Model) via HDMI (2.0 high speed cable) and the screen goes black then comes back in a second or 2. seems to be worse in a browser or streaming anything. But it also happens just with the desktop showing. It's like some kind of sync issue? I have tested with a different HDMI cable and get the same results.


I just installed windows 10 home (fully updated) yesterday and updated the NUC with all the latest updates.

HDD: Crucial MX300 525GB 3D NAND SATA M.2 (2280) Internal SSD - CT525MX300SSD4

RAM: Crucial 16GB Single DDR4 2133 MT/s (PC4-17000) DR x8 SODIMM 260-Pin Memory - CT16G4SFD8213


Also it runs fine on an LG ultra wide 34" monitor.


Any tv or graphics config thoughts?

Do the following,

  2. Ensure you have the latest HDMI firmware installed. Latest firmware is 1.77.93. You can download its installer from here:
  3. Ensure you have the latest Graphics driver for this NUC installed. The latest driver package is listed as being If you are running on an older version, install this one from here: and give it a try.
  4. If you still have problems, skip forward and go with the latest Graphics driver Intel released, namely version You can download its installer from here:
  5. If after all this you still have problems, I suggest that you switch over and connect this monitor to the USB-C port. You can get USB-C-to-DisplayPort and USB-C-to-HDMI adapters fairly cheap. Here are some examples:



Edit: If you start to look at using USB-C, you should also update the Thunderbolt 3 drivers. The current versions is 66. You can download its install package from here:


Hope this helps,

Thanks for the advice especially on the USB-C to HDMI. This fixed it. Here's why. I bought an USB-C to HDMI adapter to plug in my existing HDMI cable. When I did this it forced the tv refresh to 30 from 60 which where I had it set. This stopped the black outs.


I removed the adapter and then set the HDMI refresh to 30 and now it's fixed.


Thanks again!
