ASUS ROG PG279Q vs Acer Predator XB271HU

post #1 of 9
Thread Starter 
i'm thinking of getting a gsync screen. the above two models seem to be the current 'best' the market has to offer in terms of 1440p+ and 144hz and gsync, correct?

however I'm reading only about horrible QC. is it really that bad? wait for other models, or just get one ? is it worth and is anyone here having either of these and can report?

[Bump] I too am wondering the same question, but haven't seen any answers

Don't forget that, monitor QC issues aside, theres also the G-sync 'line down the middle' issue which both monitors suffer from. And which people are still waiting for a fix from, and may need to take their monitors into a service centre to sort out (aka no selfapplied firmware update).

The general sentiment i've observed regarding the OP's question is that:

- the current QC and panel issues people are experiencing are ridiculous, when considering the monitors premium pricepoint
- both asus/acer models can be a lottery. You can get a good or bad one regardless of which you choose.
- but the acer panel, overall, is slightly better.
- (which sucks because everyone prefers the build quality, osc and aesthetics of the Asus model).

I feel you, I've been studying monitors for the past year and half, looking at every technology such as 144hz, gsync, tn vs ips vs va and my conclusion is this. 144hz 1080p is right now, the key, lots of different models and prices going down for the past 3 years. New AOC models just came out, under 190 pounds.

As far as high-end monitors, gsync/1440p/144hz/IPS, the XB271HU did seem to fix some of the issues with previous models, however, at the end of the day, it's a lottery, same for ROG PG, same for every high end model.

If you can return them easily and you are prepared to send back 4/5, in a few month you will have one of the best monitors on the planet.

The only exception I've seen to this is the S2716DG, while TN, this monitor seems to be actually high quality with stellar reviews.

My personal decision is to wait until 1440p/144hz/IPS becomes more common and perhaps nvidia decides to allow freesync to work (very unlikely). As it stands, it costs less to setup a triple 144hz non-gsync monitor setup than a single high-end 1440p 144hz gsync.

In fact the "line down the middle"-issue is not a real problem at all and not all monitors do have it.
I own both monitors and have never seen this behavior. From the descriptions: you have to tab in and out from games to desktop many times to see this issue one time in hours. And it's gone when you tab again. That's all.
For this minor issue I would not send it to service for an update.

As far as I know (correct me if I'm wrong) Asus and Acer use the same Panels from AUO
http://www.panelook.com/M270DAN02.3_AUO_27.0_LCM_overview_23628.html
I can't see any differences between the quality or coating of the monitors.

But there is a difference in QC. I guess Asus bought the complete first panel charge from AUO. Including all the issues a first charge has to offer.
Acer bought later and benefits from panels with less production mistakes.

Overall I think it is easyer to find a good Acer. But luck is a wh...
So you have to try it by your own and hope for the best.

My understanding is its an issue with the gsync module, and thus all of these asus/acer models have the problem.

The question is, however, whether their owners will trigger it never/rarely/often by nature of how they use the monitor.. In this case, it appears to be related to alt tabbing between full screen games etc etc.

The Acer XB271HU and Asus PG279Q use different panels from AUO. The Acer uses M270DAN02.6 and the Asus uses M270DAN02.3. You can search the respective forums about this.

QC is bad for both. I tried an Asus again earlier this year after Asus was supposedly checking for BLB. All marketing BS. The monitor had horrible BLB and dead pixels. All PG279's I tried were much darker at the top 1/4 of the screen. Confirmed by my colorimeter luminance testing. I posted in the Asus thread, can't remember the details, but I think there was about a 700K difference from top to bottom of my screen.

Acer still suffers from BLB and dead pixels, but BLB is generally much less of an issue. Uniformity is much better than Asus although it is still a lottery. Several people have reported BLB decreases on the Acer as time goes by, I'd agree with that based on my own experience. Mileage varies.

The "line down the middle" issue has occurred maybe 3-5 times since April when I bought my latest monitor (Acer XB271HU). It doesn't have anything to do with alt-tabbing, at least in my case. It just happens. I just turn the monitor off and right back on, and it is gone.

If you have a Frys or Microcenter or other store nearby you should buy locally to take advantage of product replacement plans. Hopefully these stores will be able to apply the firmware update when it gets released (fingers crossed) so we don't have to send our monitors out. It took me over 10 tries to get a good monitor, it is not leaving my sight.

So I wasn't that wrong. When you are right the M270DAN02.3 and the M270DAN02.6 are nearly identical. This kind of evolving steps are not related to greater changes in technology or behavior (panelook.com).
It's just a debugging thing (changed the version number at the end).
So Asus bought the first charges and Acer the later ones.
It would not surprise me if later Asus units would be delivered with newer panel numbers.

As a recent owner of a Acer Predator XB271HU... I can state the monitor is awesome for me. Minimal BLB, no dead pixels, very solidly build compared to my last monitor. Also the 1440p resolution and 144hz native is pretty sweet.

Only issue I've run into is running 144hz in Windows 10 will sometimes cause a weird glitch where a bar on the far left around 1/8" of a inch will appear that looks to mirror of something on my screen... doesn't happen often. I'm running at 100hz right now but have G-sync enabled.
