Hey Guys,

Had my XB271HU for 3months now.
Had many issues with flicker and "No signal" running 144hz 1440p. I have now tried 7 Different Display port cables. 5 Didn't display the picture at 144hz at all, 1 does and It Flickers and gives no signal untill I remove and plug the cable back in or power off the monitor by the switch.

Any solutions?

I use a cablematters display port cable with no issues at all.

Stock cable wasn't long enough.

I need 2m+

That's a tough one. I know 1440p @144Hz is pushing the limit of DP so if there's any signal degradation at all you run into issues. They make active display port extenders but I think they only go up to 60Hz, which defeats the purpose.

Do you still have issues if you lower the refresh rate? 100Hz? 60Hz?

Turns out mine isn't as perfect as I thought... While the white uniformity is good, the lower right corner is tinted blue. It literally drives me nuts when reading because my eyes pick up a change in background color every line I read....

Should I return it?

also the BLB is worse than I thought (i should have tested in pitch black room).

Slightly overexposed this time, it's not as bad IRL, but I made it overexposed intentionally to show all "leak"spots, no matter how small:



The BLB means pretty much squat to me (I never play in darkness, and in dim light it's impossible to see it) but it WILL hurt resale value.

The blueish "right side" sucks though. I do a lot of browsing and I sadly notice it a lot. I don't mind slight irregularities of white but this one kinda "hits you", very easy to notice if you drag something gray from left corner to right, near the right side it suddenly gets blue-ish. It's quite significant sadly. I wouldn't mind minor "colder" whites there but the gray turns blueish, for instance, in a very obvious way.


Since there's a promotion in one of the supermarkets near me (400PLN cheaper), I ordered another XB271HU for comparison. We'll see if it's any better.

it's really hard to catch this issue on a photo, but try to do a quick glance from left to right and you'll see how kinda gold tinted grey becomes blue tinted.



Doesn't help that there's a slightly "warmer" spot RIGHT BEFORE the colder spot, which contributes to the "shock" for the eyes when you're reading.

Then again, those things (both) are very minor and judging from the pics in this thread - way less problematic than massive BLB and huge uniformity issues these monitors tend to exhibit at times.

I'll compare it with the second one and probably keep the better.

I feel that this panel is more about finding one you find acceptable than finding a great one.

Edit: I don't think perfect brightness uniformity is ever going to happen with these but you should be able to manage alright color temp variance.

For a 25 point measurement with my monitor at 90 cd/m²:
My color temp variance is around 4% at the worst and 1.04% on average.
My brightness uniformity is 20ish% at its worst (albeit purposely positioned at the worst point I could manage in a corner) and 11.04% on average for 100%.

I agree. My u2412m has spoiled me in this matter as it is perfect.

I guess I'm pretty picky. Question is, is it worth it? I still believe it's a very good panel. Would you try to get a better one?

We need a better pic for grey uniformity, but it seems you got the same yellow vertical band near the middle I have with my first XB271HU.
If the color temp shift annoy you then send it back. As I said my 1st one had a temp shift near the middle, which was really annoying while browsing ie.
The 2nd one I'm using now has the same problem but this time it's just a small fraction of the right side that is slightly blueish. It's not perfect at all but its "acceptable" I guess, as long as it doesn't annoy me.
