I've ordered grade B S2714DG monitor on 4th of June, got it 5th of June. Outside box seemed a bit damaged, inside contents all newly sealed and the screen seemed like it was never touched.
I connected the monitor via DP, first impressions instantly I was amazed since it has been first time since 2011 I upgraded monitor and old one is obviously dated and only 60hz. I noticed right away that the screen is way too bright for my liking but I figured I'll just get used to it.
Anyways, the problem.
After a day or two I started seeing issues, which were probably there before but I just failed to notice them as I was just amazed at difference from old monitor. First of, the screen has weirdly blurry text, I couldn't fix it with cleartype or anything, but that's least of my worries...at the same time it is really annoying. Second of all, the screen is making subtle horizontal lines (you can almost see sort of a refresh rate lines, but my hz is set to 144 and I changed to lower, didn't seem to help) and has a slight backlight flicker it seems, mostly noticeable on the top of the screen but it's throughout I am certain and it's in general hard to capture or see if the screen is bright. While this all happens on desktop, enabling G-SYNC and being in game it seems like it gets worse as I play on, if there are many explosions nearby or if I go at fast speed in a vehicle etc. HDMI connection however is flawless and nothing flickers, so where do you think the problem is at? I doubt it could be just a bad DP cable or driver issue since everything is up to date. Appreciate any help.
Here is a video of the backlight flicker, not entirely sure how to describe it since it doesn't exactly flicker but you know what I mean when you see this.
PS. I captured it with screen being upside down, as honestly the camera doesn't pick up the flicker when it's standing normally...well at least the camera I got.
