I swapped my BenQ XL2720Z for a XB271HU last night. I was first going for a LG 32GK850G, but the 1yr warranty (Canada) and the VA motion blur kind of killed the deal for me.

Here are my thoughts so far :

- Much nicer/vivid colors vs the XL2720Z TN panel.
- Almost no Bezel. The XL2720Z had a very large one all around the screen.
-G-SYNC provides a smoother experience when frames drop below 60.
- 1440p vs 1080p .. I'll need some time to adapt. Everything in Windows is much smaller. I tried to set the scaling to 125% and it looked blurry.
- Might need to swap my 1070, I feel like it won't be enough for newer games for 1440p@144Hz Ultra.

I don't see any dead pixels as well.

As for BLB/IPS glow, I'm not entirely sure. It seems like I might have minor glow in the bottom right corner, it's hard to tell since it is my first IPS panel and I can't do comparison. I don't think I'm going to return it for another one.
Most people seem to run this monitor at <30 brightness, I find it to be way too dark. I'm currently at 50 and it feels OK to me.

Do you also notice the slight darkening on the left/right edges in bright images? Kind of like a viewing angle thing, but it's just the backlight being darker there.

The thicker bezeled Asus etc. don't have that effect.

Yes, I do.

I've read the Asus had more BLB problems because of the way they're built .. that's why I went with Acer. Also because I could order it from Costco (90 days return) and wanted to be able to return it without hassles locally.

I tested the XF270HUA (with some games, lagom/eizo tests etc) yesterday. Overall i think its a good monitor, has some minor blb/homogenity issues,g2g transitions noticable faster than on my VA models, the sharpness of the text was not a problem for me at all.

But i already returned the monitor, because i personally can't stand the degree of IPS glow on this model. This is just my personal preference (i made the switch from ips to va models for my desktop pc about 3 years ago because i really dislike ips glow), but for me the glow was really unpleasant even at 0% brightness.

Although i wont be ordering another one again (will stay with my VA models with all their flaws for the time being), i think overall that it is a good monitor if you can get it for a good price and if you don't mind IPS glow.

So it seems there's no sharpness problem with these monitors, it's all about pixel walk after all http://www.overclock.net/forum/27200985-post7994.html

Tried on full screen, scrolling and window mode and it happens the same as on this user's unit. I've never had text reading issues as I've been stating since I first powered on this monitor.

Hello, I have XF270HUA (zero frame). Can someone advice good settings for this monitor? Currently I adjusted brightness to 17 contrast left on 50, black boost also left on 5. However I don't know proper settings for color settings (Rgain, Rbias and etc) and there is 6 axis hue settings, I completely don't know their functions.

It varies from unit to unit, here're my settings anyway

I bought a refurb for $317. No dead or stuck pixels, no scratches. Pretty much perfect at first sight. Except for one thing, the whites seem really yellow compared to my QNIX QX2710LED. I've tried changing some settings but I just can't get it to match the whites on the QNIX or even my secondary display which is an Acer 1440p 60hz IPS K272HUL. I've checked the power on time in the hidden menu and it's over 4700 hours. Here's an image of the difference between whites (Left to right: XF270HU, QNIX QX2710LED, Acer K272HUL)

The only thing you can change without ruining something else in the process is color gains and brightness. The variance between M270DAN2.x panels is huge there are no "type this in settings" everyone can use, use your brain.

Some units are yellowy because of bleed, some maybe because of backlight or poor hardware calibration. Can happen to any LCD.

Blur vs refresh rate there is no change on 60Hz it's still blurry as hell compared to neutral sharpness monitors. Inversion what ever, sure can have an impact at times but the sharpness from my experience is due to Acer's mess up in firmware not due to inversion handling, clock phase and what not.

They could have patched it, updated it long ago. A blurry monitor should never go to market no matter what the cause is, period.

I could take a look at the LG 32GK850G a friend of mine recently bought and oh man that thing really has fuzzy text, XF270HUA isn't the sharpest 27" 1440p panel out there but text reading is not an issue.

Bought the xf270hua and the worst complaint I have about it is bad color uniformity. All white screen is yellowish in the middle and bluish nearing the sides. Annoyingly noticeable when browsing, not at all noticeable when gaming etc. No dead pixels, pretty large area of blb in the top right corner, even larger than bottom right which I've read has it on all units. I don't find the blb that much of an issue, but these uneven colors are bugging me.



Probably going to return and get some other monitor, but if this noticeable color uniformity is a rare issue I might give another unit a try. So does this problem affect all the units or did I get an exceptionally bad one in this respect?

It is a "feature", and I think this XF270HU uses discarded panels that weren't good enough for the XB271HU so it's even more exaggerated. I haven't had color shift noticeable by naked eye on the XB271HU's I've owned, except for the vignetting sides due to the zero frame build.

Ok reading this thread further according to username JackyCY 4/4 of his xf270hua's had bad color temperature uniformity. Guess there's no winning that lottery then with others units.

The difference in color temperatures is not slight, it's severe. Will have to return the monitor and find something else, maybe the 32" LG VA freesync once it's available.

Bummer.

Color temp. uniformity on all my units was not good. The corners on right side are also common issue on all Acer frameless IPS. Some units are better some worse. Even if you find a perfect unit, that does not exist, you will still be left with image blur that all units suffer from.

Right now, wait for VG0 or other replacements of this panel in hopefully a better iteration of the panel and electronics, hopefully without the color temp. uniformity issues and blur. BLB and glow... they will never learn to mass produce decent frames for the panels be it their metal frames by AUO or plastic shells by monitor makers.

You can find all my photos in previous posts. And reports from other people often in text in all these AUO IPS threads.

The color temp. uniformity issue is very annoying for office use and even some games. Plus many units suffer from stuck bright pixels too. I really would not be surprised if they use QC rejects and better panels go to more expensive XB variants, a speculation.

I've tried:
AG322QCX (Samsung 31.5" HG70) smearing and other issues, no thanks.
XF270HUA, so many issues that even for 405 EUR it's not worth it and I would rather use an old 1080p TN with neutral sharpness than XF270HUA.
Tried C27HG70, endless defects again, 470 EUR, don't like the curve as it distorts the image and is not suitable for serious gaming.

And that's all the 120Hz+ 1440p panels there are that aren't TN.

Right now the wait is for AUO flat VA that isn't ridiculously priced. More panels are supposedly in making but that's 2018 manufacturing = maybe in 2019 some will get to market, LG, Samsung etc. 3 years behind AUO in offering faster panels especially officially so that companies do not limit them to 60-75Hz only even if they could run 100Hz fine.
A new AUO AHVA might get released in the Acer VG0 this summer but no details yet despite Computex, "reviewers" not covering or asking about monitors really :( Reviewers have stopped grilling companies about monitors long ago and the whole market stagnates and dies off overall.

Nvidia is pushing BFG so that they can get on the TV "game" as many people are buying TVs for console and PC use. The thing is, Nvidia will lose that since consoles support adaptive sync not Gsync and for only PC use these huge panels won't sell that well at their ridiculous prices compared to cheaper TVs with adaptive sync.

There is a summary of what might get released and when here: http://www.tftcentral.co.uk/articles/high_refresh_rate.htm

Personally right now waiting for LG 32GK850F or other monitors that might offer this flat AUO VA and Acer VG0 or other with newer AUO AHVA panel.
LG 32GK850G is pricey, probably suffers from image blur and there are some common annoying issues with it.

A VA vs IPS comparison is here: http://www.overclock.net/forum/44-monitors-displays/1681497-va-vs-ips-comparison-27-1440p-144hz.html
So you know what you're getting into with both.

Personally I'm having a go with the Eizo FS2735 now, 990€. I need to see it for myself if they really try to sell an XF270HUA QC-tier product, you'd think for that extra price they got plenty of bad unit returns and maybe learned something.

Hey all, I just become an owner of this model and what I noticed is that in games (OW, HOTS, WOW) when I move I notice its not smooth its like blurry even on overdrive set to extreme. In practice when I stand still everything is sharp when I move it becomes slightly blurry and after I stop is sharp again. This causes me some discomfort. Is it common because it is an IPS panel? I am comparing this to TN panel (AOC AG271QX).

You shouldnt notice that much difference. TN panels has average 3-4ms response times. XF270HUA probably 7ms. 144hz 7ms should be ok.

I think its not good enough for gaming and price is insane. It has bad freesync range and bad overdrive. But im sure it has better qc and less ips glow. So Acer is actually better and much much cheaper but you need luck with it lol.

I think Acer has the worst OD implementation of them all (and like with Asus, gamma can be anything between 2.0-2.3 with no OSD options to fix). Eizo is known for bad strobing though, but I don't care about that or g-sync/freesync, as long as modern AAA games keep omitting framerate limiter options for input lag free VRR.
