I had that issue

Its latency

Either replace the cable with a hdr10 cable usually the one included with the xbox and not have anything beteeen the tv and the xbox and hdmi 1 so no amp etc

If you want aound out do it properly and hook everything to your tv except the stereo and the optical out

This reducea latency

The more things you have between devices the more thoroughput you lose along the way

Have you tried the one that comes with the xbox one x ? Its ratedfor hdr10

And not all cables are created equal

Also I have a samsung

Yes of course - i used the one that originally came with the Xbox One X. Even swapped ends just in case. What I have found interesting enough is that by changing the video Display Fidelity setting on the Xbox One X from 12 bit to 10 bit, the blinking stopped.

Now I left it at 10 bit for a few days and last night out of curiosity changed it back to 12 bit and the blinking was not present. So It is very odd indeed.

Wonder if it's something in the refresh rates. Might go back into your settings and make sure they are high enough. A low refresh rate can cause screen flicker.

Help me remember, where are the re-fresh rates in the xbox One X - In the Advanced Video Modes? I believe I have all checked all that are not grayed out.
