Samsung HG40EA790MS: Contrast blur/shadow while using Freesync from a Q80r Samsung TV on a...

If you go into general tv and display options on your Xbox one, you can calibrate it with your new tv.

I hope this works for you.

Hey Paul!

Not a resolution problem but a VRR/FreeSync issue. The XboxOneX detects my TV and enables Automatic Game mode and VRR/FreeSync. But I'm seeing these rolling bars. I can turn off VRR/FreeSync on both 1440p@120Hz and 4K@60Hz and the problem is gone.

So it's a VRR/FreeSync issue. I'm seeing on YouTube others demonstrating this new TV with these gaming features with XboxOneX and all of them have rolling bars. Some say they cant see it and that it can only bee seen when watching a recording because of
the refresh rate. But I can clearly see it.

So either I have some super eyes. Or there's something wrong somewhere or others claiming they cant see it haven't noticed it yet. An example of that is clouding on LCD TV's. People I know dont know what that is until I explain it and show it on their TV's.
Then they see it all the time suddenly....

It's the 2019 Samsung Q80R and this model only utilizes 2.0b.

I have a samsung QLED Q80R and I have the same problem.

Currently Samsung Q8FN (and Q7F, Q9F) TVs only support 120Hz Freesync at 1080P. For more info, see the news article here.

There are some very detailed in depth 3rd party testing results of this TV series here.

Scroll down about half way to see the Variable Refresh Rates section.

Bottom line 1080p will get you 120Hz Freesync, 1440p or 4K will only get 60Hz Freesync.
