To test the PA32UCG’s grayscale, gamma and color accuracy, we focused on the four modes most used in today’s gaming, photography and video content – Rec.709, DCI-P3, Adobe RGB and Rec.2020. Each mode was set to different gamma and color temp standards and the results were averaged for comparison.
Grayscale and Gamma Tracking
The PA32UCG has both sRGB and Rec.709 presets. sRGB locks out most image controls including brightness, so we measured Rec.709 which has the same color gamut. Color temp was set to 6500K and gamma was 2.4. As you can see, it hits the marks almost perfectly. There are no visible errors.
Rec.2020 mode also came with a 6500K color temp and 2.4 gamma. It too measures perfectly out of the box.
For photographers, Adobe RGB is a useful mode that adds a lot of extra red to the gamut. The PA32UCG defaults to 6500K and 2.2 here as well. Our test run is right in line with the standard.
The DCI-P3 mode defaults to a theater setting. That means a color temp of 6300K which is slightly green. This is done to compensate for the Xenon bulbs used in digital cinema projectors. Gamma is set to 2.6, Asus calls it P3 Theater in the menu. For film post production, the PA32UCG is ready for work with no tweaking necessary. The only flaw is a bump in gamma at the 10% level. This translates to shadow detail that’s a little too dark.
The consumer version of DCI-P3 uses a 6500K color temp and 2.2 gamma. It is commonly found in games and video content on Ultra HD Blu-ray and streaming platforms. To set this option, choose the DCI-P3 picture mode and change the gamma to 2.2 and the color temp to 6500K.
As you can see in all the charts, the PA32UCG is properly calibrated and set up at the factory, very impressive.
To derive a single number for comparison to the other monitors, we averaged the grayscale error, gamma deviation and gamma value range of the five modes shown in our Calman charts. 1.53dE is an excellent default grayscale value and indicates there are no visible errors. Nearly all the values are under 2dE in all modes. Gamma also tracks true to its standards no matter what the setting. You can be sure that if you set a value, you get that value with no visible errors.
Color Gamut Accuracy
For the PA32UCG’s color test, we averaged the error levels for the same five picture modes, Rec.709, DCI-P3, Adobe RGB and Rec.2020. Each chart is rendered with the intended gamma standard for that mode, 2.4 for Rec.709 and Rec.2020, 2.2 for Adobe RGB and DCI-P3 Consumer, and 2.6 for DCI-P3 Theater.
These test results are nothing short of amazing. In every case, the PA32UCG measures right on target. The only exception is Rec.2020 where the monitor runs out of color just short of the 100% saturation points. The error stays low because every other point is correct.
You can see just how low all the errors are in each chart. Remember that the average value we report is calculated from 31 measurements, five saturation levels for each color plus the white point. To achieve less than 1dE in this test requires a very precise and accurate display.
We doubt there is another computer monitor available that can match overall color accuracy with the PA32UCG. The 1.06dE result charted above is the average of five picture modes, each derived from 31 measurements. That’s 155 color measurements that average just 1.06dE. Remember that we have not performed a calibration here. These are out-of-box results.
In the gamut volume test, we measured the PA32UCG at 95% coverage of DCI-P3. This is higher than nearly every monitor we’ve reviewed. Given its native gamut, it could cover 100% by increasing its saturation for green and blue. But the measured error is not visible to the naked eye. We calculated the Rec.2020 coverage at 77.82%. This is also a record for us.

This is a terrible gaming monitor are you kidding? 5ms gtg response time? Blur and ghosting galore. I would NEVER game on anything unless it was a 1ms gtg response time. And these speeds have been out forever. Sure the image quality and brightness and resolution are insane. great for working with graphics. but not fast moving movies' images and especially not gaming. Would love to see some HONEST reviews and headlines that are just not meant to sell products.Reply
This is for photo and video editing, or ART. ART, it's called the ProART.superop said:This is a terrible gaming monitor are you kidding? 5ms gtg response time? Blur and ghosting galore.

I see the headline now, yeah they need to take that out
i agree 100%. but look at the title of the reviewReply
Professional Gaming Monitor Review: Everything AND The Kitchen Sink"
No. just false.
So you have measured the brightness uniformity but what about color uniformity? I wouldn't care for the first one too much if white was getting blueish or redish tint here and there which seems to be the norm except in some higher NEC and EIZO models.Reply
a $5000 + tax monitor to color correct the next blockbuster film on... maybe if they took a zero off of the price tag, sure. Also, you can just calm t f down, 5ms isn't that bad.Reply
You're clearly not a gamer. Try playing any fast action like call of duty on 5ms and it looks terrible. 1ms or .5 fast ips looks amazing . Just pointing out the obviously so some uneducated rich kid doesn't blow his money on this monitor thinking it's good for gaming. It's not by any meansReply
I'm a gamer and I couldn't care less about response times. Competitive FPS gamers on the other hand are a special breed who seem to live only to complain viciously about every monitor that has ever been released until one is released with 360hz 0.5ms, 1600 nits and RRP under $200.Reply
You're being so dramatic, 5ms is perfectly fine for almost anyone unless you happen to be playing at the elite level (top 1-5%) that would be using a TN panel anyway. I'm also willing to bet you've never actually played on a 1ms monitor since you specifically mention IPS. As there are zero IPS panels that can actually hit 1ms. Almost every monitor that says it's 1ms only hits close to that mark on the highest overdrive setting that is unusable for gaming due to the amount of overshoot. So if this monitor is actually hitting true 5ms GTG time it's right up with there with most quality gaming IPS panels that actually fall into the 3-5ms range.superop said:You're clearly not a gamer.

I created an account just to reply to all these comments about gamers. There are many types of gamers. I am not a competitive gamer and I do not like or play FPS games. Professional gamers will use a dedicated high-end gaming monitor and will not care about the color accuracy or features needed for design work.Reply
I have been looking for a 4K monitor for creative work with Adobe, DCI-P3, hardware calibrated, and the latest connections. Most 4K Adobe monitors are only 60 Hz. I also want to take advantage of my RTX 3080 video card, so G-Sync compatible. I want to enjoy games and other content at a higher refresh rate.
Yes - the title is inaccurate. What the author is really saying is this monitor is both for Professional Design and Gaming. He is referencing an earlier review of the Asus PG32UQX gaming monitor that supports design work with Adobe. The "AND The Kitchen Sink" he wanted with the PG32UQX is Dolby Vision and Thunderbolt ports. The PA32UCG is the BEST monitor for those of us who want the best of both worlds.
