AOC AGON AG271QG 144-165 Hz

[Inle]

The AOC AGON AG271QG is one of the least expensive 27" high-end gaming monitors on the market. Your money will buy you an AHVA (IPS-type) 1440p panel with a refresh rate that goes all the way up to 165 Hz, as well as a G-Sync module for sublime smoothness of in-game action.

4ms response time ? Isn't 1ms is industry standard for top of the line gaming monitors ??

For Twisted Nematic monitors...

For IPS tech 4ms is pretty good, gotta also consider that this isn't 1080p.

Cool seeing a monitor review here, very thorough, great testing tools... nice work

 

[HammerON]

Thank you for the review!!! I agree that it is nice to see a monitor review here on TPU

never understand this monitor overclocking bs.
is it just so they can sell you a 144hz monitor with the promise to POTENTIALLY get it to 165 or so? I mean if it can do that, why not do that out of the box?

also was the testing with mouse button to led light taaken from youtube: Battlenonsense?

This is the second, of many hopefully, monitor review here, and here's the first in case you guys missed it: https://www.techpowerup.com/reviews/Acer/Predator_XB271HU/

I am an owner of this monitor. I got this monitor for its price/performance. The calibration was terrible out of the box. I can say that, in my opinion, this is the most non-IPS, IPS monitor out there in terms of image presentation. However, the refresh rate is excellent, the input lag is great, and it has G-sync. Overall, I don't really have any issues with this monitor.

Wow, totally missed that one

 

[StrayKAT]

Geez. Even an AOC G-sync is out of my range. I don't know if I'm the pathetic one... or Nvidia.

Because they can't be sure that every panel will overclock to 165 Hz, there's too much leeway in the manufacturing process. That's also why they don't simply give you a 144 Hz / 165 Hz switch, letting you adjust the refresh rate in 5 Hz increments instead. I tested the famous Acer Predator X34 that didn't want to OC to 100 Hz, 95 Hz was the limit. Then a couple of months later I played around with another sample of the same monitor - that one went to 100 Hz without a hitch

As for my input-lag testing methodology, the modded mouse is used by pretty much anyone who tests it with a high-fps camera. I'm not familiar with the channel you mentioned but if they do any kind of serious monitor testing then I'm sure they have a modded gaming mouse as well It's the rest of the procedure where various testers go their own way. Some test it at a crosshair level, by shooting a gun in-game and looking for the muzzle flash. Some don't test it in-game at all. Some do the tests with G-Sync or V-Sync on. And so on, you get my drift. That's why it's important to explain the entire methodology in great detail, so you guys know exactly what I did and what do my results tell us. Of course, I consider my approach the best one, as it really focuses on raw monitor performance and reduces other factors to a minimum. That doesn't mean that the tests others are conducting are bad or wrong, though

right right, thanks for the response.
So it is indeed a 144hz monitor but potentially more as they allow you to try that.
I wonder if that also means there is no hardcap really in that maybe someone will manage to get even more out of theirs, maybe 170hz maybe even 180hz.

That's an excellent question, I wondered that as well. I even tried to get a straight answer from a couple of people in the industry but so far with no success

ah interesting, I guess/hope time will tell

Who makes the panel for this monitor? Does it mean if it is AHVA that AU Optronics makes it or?

I'm thinking if there is some rule of thumb - i.e. you can buy anything with panel made by XY Company, so you just pick the one you like visually, and go home happy (or click online happy). I could skip every step if you guys had a big monitor database so I could find anything I like, but it seems you're not quite there yet (there will be more reviews, huh?)...

For a long time now im truly impressed what AOC can to keep up the good work.

And this goes out to all monitor manufactures pleas stop with the built in speakers its just a waste of materials.

I think you need to redo the testing quite a bit if you used the Custom mode as is. The problem is that the default values of 50/50/50 are not 100%. For some reason AOC chose 65/65/65 to be the neutral value.
I was confused as my measured contrast ratio was below 700:1 when using the custom profile while the Warm profile came in at almost 1300:1.

 

[Inle]

The contrast ratio measurements from my review were made when the monitor was at factory defaults, which includes the color temperature being set to Warm. To quote myself:

At its default settings, the monitor has the brightness set to 90%, contrast to 50%, Game Color (saturation) to 100, Shadow Control to 0, gamma to Gamma1 (2.2), and color temperature to Warm.

As for 65/65/65 being the neutral value for color channels, that's an interesting observation, I'm working on getting a verification from AOC on it. The reviewed sample of the AGON AG271QG was all over the place at 65/65/65, white-point-wise. Looking forward to hearing from them!

I own this panel as well. I am not impressed with the quality control with the BLB. I RMA's my first monitor 8 days after buying it, on the second one now, and looking to get it RMA'd as well.

 

[claster17]

I returned mine on the same day I recieved it because of severeal dead pixels and heavy BLB. Second one had great native whitepoint, significantly less BLB and excellent contrast. My icc profile is listed on TFTcentral.

 

[r3v07ut10n]

thanks ill try your profile, i had my settings little lower ( by eye) -

Please review the "Free Sync" version of this monitor- its the AOC Agon AG271QX 27 inch monitor- its $369.99 on Amazon right now would more than $200 less than this monitor and instead of AHVA, it uses TN and instead of G-Sync it uses Free Sync.
