For people that has scanlines on their G7/G9/Neo G9 and having difficulties to reach basic Samsung monitor support in their country, I was able to reach the Samsung HQ and got their answer: "Scanlines are because of the limitations of the screen". While Samsung HQ admitted it , there was some confusion with my support saying that some people may say that it is all the monitors that has this problem but my support said it is not all :

" when you search the internet for an problem about an product it will always look like it is an major issue and that every product has that issue.This is an distorted view. The reason this view is distorted is because we can see the full picture.Let 's take this case for example.You have scanlines on your monitor. Of course you think "Wait is this normal?"The next thing you do is you do an google search and here you find an 1000 post about people with the same problem.Of course all alarm bels will go of and you will think that every monitor has the same problem.how ever what you can not see is the amount of monitors that have been sold world wide and do not have that issue.If there were sold 1 million devices and of those 1 million 1.000 have an problem. it is still an amazing product. but the 999.000 people who have an great monitor with out issues.will not post about it. "

They ask me if I could give them the monitor to inspect that on their side and give a replacement but I refused because I don't know if it will be the same [also what is the point if Samsung HQ admitted it's due to limits of the screen]...

Later after I ended discussion with my support, Neo G9 got released  : HDR issues, scanlines [again problems appear whenever they release a monitor] -> this proof that the example of situation that my support explained to me was totally wrong. 

I have scanlines for these images, but maybe it will be different for you:

Pixel inversion issue on most of Odyssey G7 32" :
on pixel inversion tests paterns like lagom.nl : there are some spots (green/blue/red/white) where pixels are flikering. When moving the test pattern (moving the window), these spots do not change place. They only change place when modyfing settings of the monitor [sharpness/contrast/color/black equalizer] or color of image like Night Light on Windows.

I know that nobody would watch test pattern in their daily use of that monitor, but now that websites started to add dark mode , I started to notice pixels flikering on lines (reddit post/ youtube/google search bar or in LoL)
Scanlines i can forget since it only appear on specific image but seeing pixels flikering on my daily usage....

There is lack of control quality with Samsung monitors :
Death/stuck pixels, screen becomes defective later, joystick broken, software issues
Whenever Samsung release a monitor, there are problems:
G7/G9 : Gsync flickering, scanlines issue
Neo G9: HDR issue, scanlines issue
The one who gets a defective product due to lack of control quality will fall in the hole : seeing all the problems with Samsung and will see the real image of Samsung

Last year I got the G9. It had scanlines. I got a replacement from Amazon twice. Both had scanlines. I've send all of them back and waited for the G9 Neo in the hope they fixed it. I got it now a week ago. It has scanlines. And they say "not all of them have scanlines"? I highly doubt that. It just looks like most people just don't care.

 

Also "limitation of the screen" sounds like all of them should have it. I guess it is some limitation of the technology. Maybe the Black Equalizer out of some reason?!

Same here. 
I had a g9 (call it screen nr 1, I bought more) scan lines. Dead pixel arrived when used in 240hz no dead pixel existed on lower hz in month. 

I had this nr 1 monitor on service and bought a new one in case. Screen nr 2. My second g9 had scan lines and a dead pixel (or green sub pixel) just 3h after I turned on 240hz. 

I got my nr 1 back I put it in my wife room. She used it in 3 month (60hz) no dead pixel. 
I sent my second g9 for service for the dead pixel and put back the nr 1 g9 that my wife used. 

It took 2 days and dead pixel and scan lines in 240hz. 

So I bought a new instead the neo one :smiling-face:  And guess? Yes scan lines at 240hz...

So if it's 1000 of 1 million that only have my problem then I must be the unluckiness man on earth. 3 screens bought on different time span with exactly the same issue. 

And 5 sold screens from a retailer near me, 3 of them posted on a forum about the same problem. The 2 others might not run the screen in 240hz I guess. 

Two friends of mine also got the old g9. They have the exactly same problem now when they got hands on GPU that can make the monitor run in 240hz. 

So it's so strange for me that we must be the 1000 of 1 million. For me it's 100% of all screens I have seen, tested IRL. So it's maybe more like 1000 are fine 1 million are not!

I have scanlines too on G9 Neo. No settings can remove them. They are only visible in blue range tho. As far as I can tell, they are mostly visible on RED and BLUE pixels. Anything that is a mix of rgb colors has it less visible. Seems like there is pixel issue/power/something.

Happens in all modes, 120/240h\ 8/10 bit etc etc.

This is a very bad monitor.

I have the same problems , my monitor was in repair shop 2 times .

1 time it took them 2 months to not fix it and say that is normal to have scanlines on screen ( apparently this means crystal clear picture for them, fake advertising btw )

So now i have a faulty monitor , and i can't do anything about it , because samsung's engineers are "very good" in their job.

if i use G sync and VRR and HDR from windows , the asus wallpaper is just fine , but others link make my screen go wild and monitor is making a coil whine sound.

I have them at 240hz, but not 120hz on my Neo G9. This is the second unit I had with this issue. I wish they gave us multiple refresh rates to try. I would much rather run at say 200hz (making that number up) with no scanlines than 240hz with.

I regret the day i bought my G7 32". For 700 euros this monitor should be flawless but its the worst monitor you can buy. I believe that every single monitor has this problem but there are ppl that just dont care and don't report the problem. Samsung should stop shipping such faulty product and their customer service is dog *****. This is the last product i buy from samsung for a long time to come.
