Samsung G9 Neo Lines?

Howdy! 

I just got the Samsung G9 Neo. I have it plugged into the Display Port 1.4 cable that came with it. It's plugged into an RX 5700 XT

Which is DisplayPort 1.4 with DSC 1.2a. With 120hz AND FreeSync Premium Pro on I do not have any issues. Monitor looks amazing. If I switch to 240hz, or disable Freesync Premium at any hz settings the display's picture has this lines.  It's very hard to capture with a picture: Imgur: The magic of the Internet Second picture shows the lines if you look at the Edge icon. 

What I would like to know is what is going on here? Is this how the monitor is? Is this called scan lines or another issue? Samsungs web site reports scan lines in an image as gray vertical bars but that isn't it. They look like very faint lines lines like the pixel row is lowered or off.  

Thank you.

I have this same problem on a 3080, DP etc. Lines appear sometimes at 240hz. It looks like every second row of pixels is missing.

What resolution are you running? Are your GPU drivers up to date too?

This is known as "scanlines issue" and all 240hz Samsung monitors are plagued with it. You can search it in the internet and you will see tones of reports. There is no single unit not having this issue.

At 240Hz or at 120Hz VRR enabled you will have it on desktop environment. On games there is no scanlines problem on 240hz or VRR, idk why.

What I do is switching off VRR option from monitor menu and switching 240Hz from nvidia panel when playing  games and 120Hz when not playing games.
