I'll check for cursor ghosting when I get home. Can you take a photo of your blur? Did you try going to that testufo website to see if the UFOs have obvious ghosting behind them?

I think I've read other posts (maybe not for this monitor specifically) where things get screwed up and a monitor starts having bad ghosting issues... so it's possible yours is defective.

In a single monitor setup, that is unnecessary and can be dangerous.

Personally, my stick DP cable didn't work either and I saw blank screen when I used it. You need to use a VESA compliant cable like ACCELL. There are a few other brand, but Accell is a top vesa compliant cable maker and should fix your issue.
Great information, thank you. That stock cable drove me mad, it worked first time on a different build (leading me to believe cable was ok) then it started working on my current build with random outages/crashes. I read about the 20th pin issue, but I honestly wrote it off as it sounded a bit ridiculous.. Should I be worried about any hardware damage regarding the 20th pin? I don't have ACCELL brand, and after looking into the cable I just bought a bit more, I'm finding that it's also not a very good replacement. Ordering an ACCELL now, thanks!

my cursor looks like the image next to linear. that's pretty much exactly what I'm talking about its like ghosting motion blur all in one. In video games I just get a motion blur when turning the camera that's hard to look at.

I was able to almost completely get rid of the Back Light Bleed on My PG279Q using some electrical tape and small wedges of paper if you guys are interested in hearing how to do it. It does require dismantling the panel for the electrical tape part but the paper wedges do not require it.

In regards to the 20th pin, I do not thing there is any immediate damage concern. It does add a slight jolt of voltage in the cable and the connectors. It is mostly a issue if you use any sleep feature on your monitor (Deep Sleep) or from your pc. When the monitor needs to wake up, that's when the high voltage kicks in.

As for the VESA complaint brand, I stumbled upon Accell by reading some of the reviews in amazon. I was a click away from buying Amazon Basic cable before I learned about this issue. Since DP is very finicky, so please do not cheap out on cable. Get a decent well priced cable and most of you connector issues will go away

Here's what my cursor looks like (iPhone camera was doing a poor job so had to bust out DSLR)... Monitor at 144Hz, 100 brightness and Normal OD, no ULMB; Camera at 1/250s shutter and 1000 ISO:

Here's a screenshot photo from that testufo website:


As you can see, there's usually only 1-3 frames being displayed at a time, usually the current frame plus a faint ghost of the previous frame. Sometimes the photos capture the next frame starting to appear, which would give 3 total frames showing. Also, some color transitions have some bad inverse ghosting (see middle UFO) so you can see multiple frames of inverse ghosts.

What monitor were you using prior to the XB271HU? I'm just wondering if you are noticing ghosting, or if it's all motion blur? If you were using something like a CRT before this, you may just be really sensitive to motion blur...? How many frames are you seeing at once on your monitor? When I drag my mouse cursor in fast circles over a black screen, it visually appears to be like 20 cursors showing at once, but when I take a picture with the camera at high shutter speed, I only see 2 cursors (maybe a very faint third).

What if you turn on ULMB mode on your monitor (have to disable G-Sync), run at 120Hz, and view this test page with a scrolling google map? You should be able to read everything very clearly. If you turn off ULMB on the monitor, it becomes a blurry mess.

If ULMB looks great to you in games and in that test screen, then you may just be extra sensitive to motion blur.

How do you guys take screenshots without the screenshot from pausing ufo test.

So i did what you told me to. Turn off gsync and turn on ULMB and yeah i can read everything very clearly on the maps test. Games still look a little blury but its better then gsync. One more thing i noticed is that when i Opened a game the map test became extremely jittery and blurry and when i closed the game it become very readable and non blurry/jittery. is that normal?

I'm not sure, are you running games in windowed mode? It could just be that the browser doesn't like having a game running during that test, which causes stuttering but it shouldn't go blurry unless ULMB turns off. When your game is running, you can go into the monitor's menu and see in the Info screen "Mode: ULMB" if it is still on.

Also, I called it a "screenshot" but it's really a photo of the screen. Taking a screenshot wouldn't catch any of the pixel transitions, since it's just an image of what the screen was supposed to display at any given time. You probably need a pretty good camera to take a good photo that can show the ghosting. The main thing is you have to set the shutter speed to really fast, otherwise it will catch like 5-10 frames at once, more than what you actually see, and looks super blurry.
