Are you sending it back for repair again (assuming it's still under warranty) or e-waste recycling it? If no extra charge to repair, consider sending back again so Acer has another chance to make it right. Otherwise, I think it's time for the compactor to put it out of its misery and buy a new monitor.
Yeah Im giving it one more try because its only just barely over a year old. Last time I tried though, they told me "we've already repaired that" and a bunch of crap that basically amounted to "we don't believe you".
I do know this, I'll never buy an Acer product again. If it's not repaired 100% this time, it'll be recycled and Ill buy the similar specced Gigabyte one with the new panel and free myself from Nvidia in the process.

Lexi is Dumb This has been my experience with it on and off, but now its been stuck for too long to deal with anymore. Ive blamed GPUs, DP cables, and ive swapped so much stuff over and over again. When i sent the monitor back for repair, it came back good.. for a week. I continued to blame everything but the monitor, but here it is.. even stuck there with the computer off, just on the blank screen you get when you turn the monitor on without input. I've absolutely had enough, I want to throw this monitor into a compactor so no one ever has to look at it again.

I would honestly not call this great, the bottom left corner is heavily yellowed. I'd say average or below average.

Since it also has BLB, I'd return it TBH.

I would not bother trying to exchange it, but that's up to you.
Also, don't let the monitor drive you crazy ... that's what I did when I saw some IPS glow and BLB but in the end when I use my monitor I do not notice any IPS glow or BLB (My monitor has almost no BLB but some IPS glow at the corners ONLY when the screen is black like in dark movies).

Good luck.

By the way, where are you from ?
I really appreciate your feedback.

Minding the IPS Glow and BLB can really drive anyone crazy. I think I was happier before learning all those problems an LCD can have.
About the BLB, I was able to remove it almost completely by pinching the borders softly, here's a comparison:
Before: https://imgur.com/VJvAXfW
After: https://imgur.com/5bWVNj7

I was really happy about it and decided to keep it until I detected two sub pixels that turned on proportionally to the medium brightness of the pixels in the column. On some occasions they really popped out, like this one: https://imgur.com/LnaSVrO

Don't know if returning a screen with no BLB was a good call, but I did it anyway =(

About my origin, I am from northeast Brazil, state of Paraíba, but currently living at the southeast, state of Espírito Santo.

However, some backlight bleeding was visible on a black screen on a dark room, but I've found it challenging taking a picture that really represents what I really see in this scenario.

At first, I used my cellphone on auto mode and took the following picture:

I also took a picture from a greater distance to eliminate the effects of IPS Glow:

(This one was really representative, except for the disappearance of the right-bottom bleed)


I've also took a picture using RTINGS guidelines, which is F4.0, ISO-200 with a 2s shutter speed:
https://linustechtips.com/main/uploa...6f1e82ecc8.JPG
(This one captured, faintly, the BLBs on right/left bottoms and at the top center).

Finally, I recorded two videos moving around the screen with two different brightness levels:

20% brightness:

100% brightness:

What do you guys think? Is it a good or bad panel?
I have five days to return it, do you guys think I should try another one?

Sincerely,

Should I return this XB271HU because of backlight bleed?

It's an 8bit + FRC monitor, and from what I remember, you need to have an NVIDIA Quadro card in order to enable 10-bit (8bit + FRC) with this monitor.

And I think, even with a quadro, since it's FRC that is being used, you still can't get full 10-bit, just the emulation.

The AUO panel in this monitor is a full 10-bit panel, but the chips driving the panel in the geforce module/etc don't support full 10-bit.

It's pretty easy on LCDs to have non neutral sharpness due to image post processing in the firmware and even the electronics that drive the panel itself can have some of their own or simply the way they control the panel and are tuned to do it alters the final image look. It's a fine tech and there may always be an effect of adjacent/neighboring pixels on other. Hence why LCD monitors HATE fine pixel patterns such as 1px vertical, horizontal, grid patterns and some will squeal like a dying pig, even monitors that are normally silent with such patterns I have a pattern pack of endless generated images of various patterns and it's "always" possible to find at least one type of it that will make an LCD hate it and become audible. And then you have the never ending Lagom fine patterns that look normal on full screen but being only partially on screen they turn greenish etc. again that's the electronics and how the panel is controlled. And there is also on many LCDs the issue of bleeding of content on entire rows. So a notepad on right side bleeds into uniform color on left side, this is easy to test with patterns. As much as we would like each pixel to be perfect and individually controlled, that's not the case and "bleed" from neighboring pixels or even on a row is possible. The pixels are not individually controlled, there is no bloody space for that and the amount of wired connections would be absurd. As such there can be a residual charge on a row etc. that creates these unwanted artifacts.

It was only when I got this monitor to replace the PG278Q that I thought something was off and looked into sharpness.
Yes there can be a variance on the AUO AHVA M270DAN2.x in terms of perceived sharpness even between units of a single model = same firmware and maker. But it's especially true between various models of different makers. Although the differences between units of a single model can be small and imperceptible to many people especially when other issues and differences between them are much larger.

The firmware matters, so do electronics with D/A conversion and control of panel itself.
