Great colors and excellent picture quality are two of the main factors that help create immersion while your gaming. Despite the importance of good color, monitor manufacturers don’t always calibrate the color of their panels to what is deemed accurate within specific color spectrums – sRGB/Rec.709 for example.
We like to test each monitor for color reproduction to see how they would perform in color-accurate scenarios.
Here are the results for the ASUS ROG SWIFT PG32UQX.
NOTE: ASUS has pre-calibrated this monitor to an average DeltaE <2.
Like always, we began the color accuracy performance section by running a simple test on the PG32UQX right out of the box. For this monitor, Racing mode was set with a brightness of 285 candelas – more than the recommended level for daytime usage.
The colors right out of the box for this monitor were incredibly accurate. As you can see from the table above, we recorded a white balance of 6884K, decent black depth, and fantastic 3307:1 contrast ratio – much greater than the 1000:1 advertised. More impressive, however, was the 0.54 average deltaE. This makes the PG32UQX one of the most accurate gaming monitors we’ve tested – enabling it to perform color accurate work within the sRGB spectrum.
Next, we loaded the sRGB color preset. Enabling this preset would lock the brightness and contrast of the monitor – fairly standard procedure in most modern panels. We ran the tests and the results were pretty similar from an accuracy standpoint. The White point was slightly higher (6935K) and black depth rose a little (0.15cd/m2). The contrast dropped by over half and the average deltaE was nearly identical (0.56).
There was a tonne of other presets inside the monitor’s OSD, but few offered accuracy that was close to the sRGB spectrum. That said, we did take some notes on the preset which are below:
Cinema – Cinema mode offers a slightly blueish hue when compared to the sRGB preset. It also feels a little washed out in comparison, with a less gamma-rich profile.
FPS –FPS is the brightest of the GameVisual options, providing what feels like a boost in blacks – great for FPS shooters where pinpointing your enemy is critical.
RTS/RPG Mode –This preset offers a similar profile to that of sRGB. The picture feels well balanced with a wider color gamut than both FPS and scenery modes.
After testing the various presets, I wasted no time and decided to calibrate the panel – recording color gamut, panel uniformity, and overall color accuracy.
I selected the calibrated ‘out-the-box’ settings, leaving the RGB values at 127/127/127.
Here are the results:
After calibration, the color accuracy didn’t increase by much. Looking at the table, white point was now perfect but black depth was at a new low (0.16c/m2). The contrast ratio wasn’t great and gamma was set to 2.1. Average DeltaE did drop to 0.33 – with a maximum of 2.01, respectively.
Overall, the color accuracy of the PG32UQX was extremely good. I could easily recommend this monitor to gamers that like to do color accurate work (within the sRGB spectrum) on the side.
Panel uniformity is a test we run to check how uniform the luminance and color is across the entirety of the screen. During this test, the center square is used as the reference space. Every other square is then tested to see how far it differentiates from the reference.
In an ideal world, we want every square to be green, meaning it hasn’t broken the differential threshold – something we can set at the start of the test.
Note: results will differ from panel to panel.
The panel uniformity on the PG32UQX was pretty good, but nothing spectacular. As you can see from the graph above, large portions of the monitor showcased an ‘amber’ score, meaning the color/luminance of that quadrant exceeded the differential threshold of the reference quadrant – which in this scenario was a deltaE of 2.
Whilst this is a small flaw in this monitor, we should not forget that panel uniformity does differ from panel to panel. And for our monitor, viewing sporting events or content with large blocks of color was still perfectly acceptable.
The viewing angles on this monitor were incredibly good, providing excellent picture quality even when at obscure angles. Looking at the monitor from over 45 degrees does result in a small amount of luminance shift, but nothing overly obvious. Colors stayed pretty true and general viewing was perfectly acceptable, once again.
As part of the calibration process, the DisplayCal will give an accurate measurement of the color gamut the monitor can provide. Below are the results of the color gamut test:
We had to enable the ‘wide gamut’ setting in the OSD to achieve these scores.
Looking at the measurements above, we were incredibly impressed by the overall size of the color gamut this monitor provided. We recorded a total sRGB gamut volume of 184%, over 20% more than the advertised gamut. That translates to 126.8% Adobe RGB and 130.3% DCI-P3 volume – one of the largest we’ve ever tested.
Taking a closer look at the color gamut graph, you can clearly see how far the PG32UQX exceeds the sRGB spectrum – showcased by the dotted line. The PG32UQX offers a huge number of color variants in the red and green sectors – allowing for a richer, more realistic experience when in standard and HDR modes.
Pair this with the out the box accuracy of this panel, and the PG32UQX is easily one of the best monitors we’ve ever tested when it comes to color.
Maximum And Minimum Brightness
We ended the color accuracy and picture quality testing by checking the maximum brightness, minimum brightness, and 120 candelas points on this panel. The results are below:
