Our grayscale and gamma tests are described in detail here.
Grayscale Tracking

The G2770PQU comes set to the Warm color temp preset from the factory. It’s fairly close to D65, but there is excessive red and green at the 40- to 90-percent brightness levels, peaking just over the visibility threshold. The error at 100 percent is quite low, which helps the brightest highlights look correct.
Better results are just a simple calibration away.

In the User color temp mode, you can adjust the RGB sliders (although they are a little coarse for our taste). We got all the errors under three Delta E, even if the tracking is not as flat as some other monitors. It is, however, more than adequate for gaming.
Here is our comparison group:

Color and grayscale accuracy are obviously not the top priority with most gaming displays. Compared to our group, the G2770PQU’s default average error of 3.04 Delta E is pretty good.

We couldn’t quite get the grayscale error down to a one Delta E average (that’s our standard for pro screens), but we’re more than happy to see any monitor slide under a two Delta E average and AOC's G2770PQU achieves that easily. Praise goes to the BenQ XL2720Z for acing all of our grayscale accuracy tests.
Gamma Response

Gamma tracking is quite consistent using the '1' preset. Except for a dip at 90 percent, it’s almost perfect. The error is only 4.5 cd/m2. That's barely visible. The Gamma 2 preset shows the same tracking, only at a brighter (lower value) level. Gamma 3 looks similar to Gamma 1, but introduces a green tint that is difficult to correct. We recommend Gamma 1 for all applications.
Here is our comparison group again.

The dip at 90 percent hurts the gamma range result. It’s still solidly average among the monitors we’ve tested, though.
We calculate gamma deviation by simply expressing the difference from 2.2 as a percentage.

All of the gamma values ride a hair below 2.2. That, coupled with the 1.94 result at 90 percent, pulls the average down to 2.14. For gaming and video content, this looks fine. However, we’d like to see more accuracy, especially as TV and film mastering moves to the BT.1886 spec.

I completely agree. I use a benq xl2411z, and i can understand turning on the blur reduction feature at 60hz. But at 100hz and up, i just don't see the reason why. the blur reduction actually detracts from the overall experience, increases ghosting and crosstalk in particular areas of the screen. Even with modded drivers, it still doesn't seem like the best course of action.
but light reduction at around 72hz is awesome. the only issue is the flickering, but man is the picture crisp
- 2560x1440 144Hz ! !
When do we want it!?
- NOW ! !
From what i heard when you get close to 120Hz or above you almost can't see the tearing from no-sync at all vs G-Sync, but if it has it for little to now extra charge (like im hoping will happen with free-sync) then ok.. lol
But no, manufacturers insist on making it exclusive to the most high end/expensive models. They want to milk the most out of this tech by keeping it elusive.
"With speedy G-Sync-capable monitors starting to emerge, is the tech still a relevant choice?" What a stupid question to ask. Just about every monitor that comes with Gsync ARE 144Hz TN panels. Where its benefit is the least noticeable...
TN? No thank you.
Are changes coming? Yes. But who wins out at this point I think is going to be up to the market, and monitors that cost $35 more are going to be at a disadvantage if they both function equally or very close to equally.
Maybe in 6 months we will be able to see both technologies side by side, and get a better idea of what each can do. But we are nowhere near being there to make this decision today.
Got several different screens available and the TN based Asus Swift PG278Q is definatly the quickest but the picture quality price of a TN panel at that size is heavy, even at almost perfect monitor centered eyes its still borderline to wash out the colors/clarity at the edges. Compared to an Dell US UP3214Q (ips/igzo) or Dell US U3014 (ips) the TN panels is lightyears behind in picture quality (allthoo todays 4k@60hz screens have their issues with the 1.2a display port as their handeled as 2 screens).
So if you ask me, get two screens - One for quick fps style gaming and one for desktop / slower gaming.
So for a wishlist - An overdrive IPS panel 27-30" @ 120hz running 2560x1440(1600) and having G-sync (Ever tried an g-sync? if not - try it out, really hope Amd gets freesync to take off and Nvidia wises up and gets behind it)
you probably won’t be able to tell it apart from an IPS display."
Sorry, can't agree there. I have a 27" Dell IPS 2560x1440, and meanwhile I
bought my brother a 27" Samsung TN 1920x1080. Sitting directly infront of
the Samsung, I can already see the change in colour & brightness towards
the corners & edges of the screen, as the angle is large enough to reveal
the effect despite not sitting off to one side. The Dell screen looks sooo
much nicer.
I can imagine TN panels still being reasonbly ok at 24" or below, but by 27"
the sheer size means one doesn't have to sit off-axis to see the difference.
With hindsight, if I'd known the effect was going to be that visible, I'd probably
have bought him a 24" model instead, upgraded to a 27" IPS later.
Later for my gf's PC, I bought a 24" Dell 1920x1200 IPS.

shooters which I like, haven't tried driving games, look beautiful, just turn off
the Overdrive feature. Don't fall for the 27" at 1080p looks bad, its awsome. Single card setup can pump 100+ fps ( I got a gtx680 ftw 4 gig) and it shines at bf4,1080p.
This monitor is a great value.
