S3422DWG, pixel inversion artifact, v-lines
Hello!
I recently bought a 34" Dell Monitor, the new S3422DWG.
I am globally satisfied with it except on one point: there happens to be clearly faint vertical lines on all the display during camera movement in FPS's for example. It occurs only at a certain speed but is quite noticeable, and is displayed on the whole screen. It gives the picture a CRT look that I don't appreciate very much.
I found a picture online that perfectly describes the phenomenon:
I granted this to the pixel inversion artifact after consulting a few topics.
I tried several solutions such as:
- activate / deactivate freesync
- activate / deactivate HDR
- change video cable (HDMI <=> DP)
- tweak every settings of my Radeon software, and update drivers
- Lower the framerate
Unfortunately it didn't work.
Is this a "common" or "unavoidable" artifact of such UWQHD 34" VA 144 Hz panel ?
Does somebody know a way to make it disappear ?
Thanks for your attentiveness.

My monitor is connected to my 1070 with DP 1.4 and sometime switch to my job laptop on HDMI. I have the problem on both connections. It comes and goes for no apparent reason. As I'm typing this, I can see it flickers from time to time. It's really annoying and apparent on white background applications. Haven't found a fix yet. Mostly posting to see if Dell-Cares really cares on fixing this.

Hi everybody
I managed to reduce the problem by setting a custom resolution (3440*1440 @119.99hz) in CRU.
After a "restart 64" I set the frequency at 144hz in Nvidia Control Panel (No HDR, G-sync On).
Vertical lines still appears in some games (like resident evil 3) but I managed to play to others games many hours without issue.
Thank to "Monitor Profil Swicther" I can reset my resolution with a shortcut too.
I hope these 2 workarounds will help

Please try below settings on monitor:
1. Set Monitor OSD menu: Game -> AMD FreeSync Premium Pro--> Off
2. Set OS: Game --> Response Time --> MPRT
The vertical line will disappear after these settings on my monitor.

Had this same issue. I'm on a Mac and after calling in to support they sent me a new monitor. It exhibits the same behavior. However, on a whim I switched from HDMI (which connected to a USB-C Hub) to a DisplayPort to USB cable connected directly to the Mac. Once I did that the image is MUCH better and I can choose the 144Hz refresh rate in settings. With the HDMI cable I could only choose 30 or 60Hz. I'm gonna watch it the rest of today and post back if I had a good day.

So far so good. Works MUCH better on DisplayPort on a mac, no vertical line issue.
