Finally, we get to the picture testing results. As always, we used a DataColor Spyder4 Elite Colorimeter, with measurements taken of the AOC U3277PQU in its out-of-the-box, uncalibrated state, then again after calibration.
The screen is reset to factory settings before the test and calibration is done with brightness set to 120 cdm/m2, which is a setting of 40% in the OSD. By default, brightness is set to 90%.
Without running the risk of repeating ourselves, 2015 has seen a dramatic increase in the panel quality of even affordable displays. For a mid-range display, particularly one offering 10-bit colour, close to 100% sRGB coverage is now expected, with 70-80% Adobe RGB. For even greater colour accuracy, you’ll need to be looking at more expensive displays aimed specifically at graphic designers.
Firstly, the uncalibrated results of the AOC U3277PQU show 100% sRGB and 79% Adobe RGB coverage.
The panel shows some strong 15% brightness deviation on the right, but the left-hand side is quite close to the centre value.
Despite the claimed 350 cd/m2 we only measured a maximum brightness of 290.3 cd/m2. The contrast ratio is a very good 620:1 and the black point is a standard 0.47.
The Gamma 1 setting shows a measured display gamma of 2.2, Gamma 2 drops this to 2.1, while Gamma 3 is 2.4
The OSD settings show the White Point shifts from 6000K to 6800K when the Normal setting is enabled, and leaps to 8300K when in the Cool mode.
Colour accuracy is yet another area of massive improvement in displays over the last year, with the AOC U3277PQU achieving a Delta E result under 1.
Then we measured the screen again after calibration.
AdobeRGB coverage hits 80%.
The white point drops to 5800K.
And Delta E colour accuracy remains roughly the same.
Overall, the subjective view of the AOCU3277PQU picture quality is good. The screen is sharp and bright, while the colorimeter results show excellent accuracy.
With calibration the results don’t seem to change hugely, although in our subjective view, the resulting picture was less yellow. Games testing showed no problems with ghosting, and the speaker output was clear, although not especially loud, and therefore not a replacement for a proper set of stereo speakers.
Just now l Received““my“`4th paycheck of $4395 working`onIy 3 h○urs` on my Iaptop` this week. My neighbor, who lives alone with toddlers, is making over $10k/monthIy doing this & convinced me to try. It’s so user friendly and easy to do so I thought to share it with you guys… T○ SEE what I D0“`have a peek on my“`Pr○FiIe ->>> I posted website link address there… Good luck

“The AOC U3277PQU is a high-end 4K display, with a large 32-inch screen and a specification suited to graphic design work and gaming alike. It has a 10-bit IPS AHVA panel, built-in speakers, a picture-in-picture mode and a fully flexible stand – for a relatively reasonable price.”
How can anyone trust this review when the reviewer clearly doesn’t know what he is reviewing? The AOC U3277PQU is not a 4K monitor and it does not have an AHVA panel, it is a 2560×1440 monitor with an AMVA panel. I am looking at mine as I type.

You linked to the wrong product, take a closer look at the two names. You linked the Q3277 and not the U3277 reviewed here. The U in this case stands for UHD, while the Q on the product you linked to stands for QHD, explaining the difference in resolution. You should probably double-check what you are looking at if you are going to call someone out.
Any measure of input lag for this display?
Also, I thought this was an 8-bit panel with some special tech to simulate 10-bit colour range?

this is the display model which is used in this monitor. It’s clearly stated 10 bit RPG data input. (not 8 bit + FRC). The input lag is ~10 ms, which is very good result in a contrary to a new “gaming” ViewSonic XG2700-4K (23ms), look it here: http://www.displayspecifications.com/en/model/97846a8
