My graphics card is a 770, so I doubt that it doesn't have enough rendering power for higher refresh rates. I also tried a smaller resolution but that doesn't change anything. Could be some weird compatibility thing I suppose. I'll look into it.
That would of course be yet another reason to get a new card. I was strongly considering to buy one anyway. And if the refresh rate thing can be fixed that way, I'd definetely keep the monitor.

@Lotty was having the exact same problem (also 770), and @Pereb mentioned that 960+ (Or a 780TI) can hit 144Hz on these monitors. I can confirm that 780TI works, but it won't let me overclock past 144Hz. When I enable OC, I no longer get any options over 120Hz.

Yeah I found the post. So did anyone with a 960+ have any issues getting to the advertised 165Hz?
I'm looking at the 970 right now.

EDIT: found this in the manual:



Turning off G-Sync doesn't get you higher refresh rates though. I tried.

4 of these puppies in stock @ NJ microcenter, gonna go take a look tomorrow and try to pick the most recent manufactured panel, they'll probably be December models or maybe even January. Either way i'll see how it is, if its all good and has some bleed i'll give it a week and see if it improves, maybe open her up to relieve some frame pressure. Fingers crossed i get a keeper.

Decided to try one last time, my local Microcenter got some in stock. Got a Dec 2015 build. There are no dead pixels but there is still BLB in all 4 corners. Interestingly, compared to my Oct 2015 build, gamma is spot on out of the box on the "standard" setting. Even with ColorMunki Display calibration on the Oct 2015 build I still can't hit perfect gamma on all of the bars on the Lagom LCD test site. The Dec 2015 build, no adjustments at all, 2.2 across the board on that site, for what it's worth.

The Dec 2015 build has awful uniformity compared to my Oct 2015 build. Best seen in my attached YouTube screen shot where the right side of the screen shows blue tint. The photo is a pretty accurate picture of what I see. So despite the fact that this one is probably easier to calibrate, the poor uniformity is killer and is auto-return. Worst XB1 I think I've seen on here so far.

Another issue that popped up on both monitors is random hot pixels that pop up and then seem to disappear using jscreenfix...this is the first time ever that this app has actually worked, I'm shocked. Stuck green / white ones on black backgrounds. I am very nervous that this may be a bad sign of things to come with this monitor, who the heck knows. It isn't the Display Port cable, it happens when the monitor is simply plugged in showing a blank screen.

*Edit- gamed for about an hour and it gets worse the longer it is on. There are many hot pixels that come and go, using jscreenfix seems to dissipate many of them. If I press on a small part of the screen it sometimes creates a cluster of more hot pixels. If you want to test it after using the monitor for awhile turn the brightness up and bring up a solid black screen. Phantom hot pixels now...another first for me...

So I am definitely returning the Dec 2015 build with bad uniformity and never buying another one, finally. I am strongly thinking about also returning the "better," if you can call it that, Oct 2015 build and not wasting any more time and money. Luckily the BLB on the Oct 2015 build isn't visible in normal usage despite the fact that the photos make it look worse than the Dec 2015 build. But it's there. Regardless, I have never in my life seen this many issues in any product ever. Here are the pics:

How easy is it to open up the 271HU? Surely its easier than the 270HU which i've personally opened up to see what was behind the panel and it turned out it was actually scratches and not dirt/dust, unbelievable. I'm just wondering since its a "bezel-less" design and all so i take it that it just has several screws on the back. Reason i ask is the bleed issues can really be eliminated if one is brave enough to open the case and play around with the frame encompassing the panel which is just pinching the monitor causing the bleed like that.

I contacted Amazon support yesterday myself as my October model in some cases can take 2-3 tries to turn the power button on or off. Additionally, I have minor to medium black light bleed in all 4 corners. I posted a screenshot of my monitor some pages back. In normal viewing it's absolutely fine, so I'll take that as a win. They offered me a replacement or a 20% refund. I ended up taking the partial refund as I didn't want to deal with the hassle of returning it for something worse.

The refund option seems to be coming up more and more. Maybe that is their solution to keep these returns to a minimum now?

Wow, the hot pixel thing is definitely worrisome... I can't believe their QC is actually getting worse!

Interesting that the gamma is correct on the Dec builds. I've been playing with my Oct build for the last two weeks trying to get optimal settings, and I noticed that the screwy gamma gets worse the higher you change that black level setting. The feature is intended to expose more detail in darks for gamers, but it really just washes them out. Anyway, it's as though it still applies a small amount of that feature, even when it's disabled. So it might be something they fixed since the Oct firmware.

If you decide to keep your Oct panel, I can send you the settings and profile I came up with that fix nearly all the problems.

BTW what camera settings did you use for those BLB pics? I want to take similar ones of my panel for comparison.

Also, if you do give up on the XB1, you should probably skip 144Hz IPS altogether for now, since AUO is the only company making them and they are awful at manufacturing anything reliably. I saw that review of 20 PG279Qs, and BLB varied from mediocre to godawful.

However, not all of that can be blamed on AUO. Considering the XB and PG use pretty much the same panel, why is it that the PG has significantly worse problems with BLB than the XB? People on this forum have proven that it comes down to the design of the frame and the pressure that is being applied to the panel. The design of the Asus results in much higher BLB than the XB. Without a redesign, they are not going to improve this.
