The OSD settings buttons are on that side and may be playing into this. I wonder if you had a black full screen of MS paint open in a dark room, looking at the glow, if you could press the bezel tighter together with your hands slightly and see the glow become dimmer?

The question you have to ask yourself, is it noticeable when your doing the normal things you do? and not just when looking for it. If not, then your good. If you can see it and it's distracting from deep blacks, then it's a lot to pay for a monitor to 'settle'.

well on the pictures i took today, that actually exagerate the glow, we can see it at 3 or even 4 corners but smaller....

100% brightness :



0% brightness :



but here we dont see it that much :

so i guess it's actually ips glow.... and it disappear regarding angles.

I'd test mine where I keep settings.

For me 30% Brightness / 75 % Contrast 6500K. IPS above 30% is a lot.

I don't think the glow is caused by BLB or bezel issues. The glow can completely go away if you look at it from an extreme angle. I think the glow is just an artifact of this type of AHVA LCD.

Definitely looks like IPS glow. The thing that makes IPS glow so hard to demonstrate is how it show up in the camera. It often looks so radically different (depending on the camera and settings of course) then how it looks in real life. The thing is that the Yellow/pink glow can also be see on pictures taken of TN panels as well. I'm not exactly sure what the actually cause is but I suspect its has to do with polarization films and the fact that cameras pick up the infra red spectrum.

I have glow. Its not really noticable in normal use unless i look for it, but even when watching a video it is apparent as a slightly redder/lighter region on the lower-right edge & corner. Similar to my experience with my previous IPS. I would take this anyday over the artifacts in a TN panel.

OMG, this exactly like my panel. I set brightness between 25-35 and glow is closer to the bottom image. To be honest, I am about to return mine because I expect perfection and more than one input for $800... What's crazy my $350 Acer K272HUL has better panel uniformity, less IPS glow but of course it is 60Hz... I will try my set of games with Adaptive Sync tonight and compare to 144Hz/G-Sync.

I am asking myself right now: is 144Hz plus G-Sync worth $450 at the expense of IPS glow and lack of inputs. Tough to swallow

Guys, IPS glow is unavoidable. It's a side-effect of the panel technology. Unless an A-TW polarizer film is applied to the monitor (currently only done on very high-end monitors for the professional graphics industry), you will have IPS glow. Some panels maybe a bit less than others, but unavoidable nonetheless. Either way, it is not a defect, it's the way the technology works. And it's more easily seen on a large 27" monitor vs. a smaller 24" monitor, just because there is more surface area and the outer most edges are at a more extreme angle relative to your eyes. If you really want to deal with it, sit a bit further from your screen, which should reduce the glow. It's only visible at the more extreme angles.

Backlight bleed on the other hand IS a defect and is something you'll see no matter the viewing angle. And that is something worth exchanging the monitor for.

Does this look like a reasonable amount of bleed or do you think i should try and get a better one?

was taken with 2.2 Gamma and 45 contrast
