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 STRIX XG43UQ.

NOTE: ASUS has pre-calibrated this monitor to an average DeltaE <2.

We started the color accuracy performance section by running a preliminary test on the XG43UQ right out of the box. For this monitor, the ‘Racing mode’ preset was installed, setting the brightness to 254 candelas – more than the recommended luminance for everyday usage.

The colors of the XG43UQ in the out the box settings weren’t terrible by any means. Granted, they weren’t the best we’ve ever seen – but they weren’t the worst either. We recorded a white balance of 6090K (slightly below IDEAL) and a decent black depth of 0.0294 cd/m². Contrast ratio scored higher than the rated 4000:1 (4171:1) and gamma was set to 2.21. Average deltaE came in at 2.62, making the RACING Mode preset OK for color accuracy – but not amazing. 

I wasted no time and loaded up the sRGB preset to see whether or not the monitor was pre-calibrated to a deltaE of <2. The results were strong in the sRGB preset, showcasing a perfect white balance and good black depth (0.0324 cd/m²). Contrast ratio did dip slightly (3782:1) whilst gamma stayed solid at 2.25. Most impressive, however, was the 0.98 average deltaE. Whilst it wasn’t the 0.85 that ASUS state in their color calibration testing report, it was close enough. 

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:

Scenery – Scenery Mode offers more vibrance and a more gamma-rich viewing experience. Brightness is definitely increased on this setting, pushing it over the recommended 120 candelas threshold.

Cinema – Cinema Mode gives the XG43UQ a blueish hue that is definitely noticeable when compared to other presets in the monitor’s GameVisual arsenal.

RTS/RPG Mode –This preset offers a similar profile to that of sRGB. The colors feel well-balanced, with orange/red colors popping.

MOBA – Moba was the worst preset I tested, washing out many of the colors and making it look almost black and white.

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 ‘User’ settings for the calibration, changing the RGB values to 96/96/100. 

Here are the results:

After calibration, we were able to reduce the overall average deltaE quite considerably. The white balance stayed consistent at around 6500K, as did black depth (0.0295). The contrast ratio took a slight dip to 3905:1, whilst gamma resulted in a 2.22 reading. The average DeltaE after calibration read 0.37 – an increase in accuracy of roughly 62%. That being said, we still got a maximum deltaE of 2.06 – which was a little disappointing, but still perfectly acceptable for color-accurate work within the sRGB spectrum.

Overall, the color accuracy of the XG43UQ was pretty decent. I could easily recommend this monitor for gamers that like to play various titles and need a good sRGB preset for color-accurate work.

Panel Uniformity

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.

Panel uniformity XG43UQ min

The panel uniformity for this display was surprisingly good, with both average deltaE and luminance across the board offering up a decent score. As you can see from the graph above, the left-hand side of the monitor does offer the worst uniformity. However, with an amber score, you aren’t going to notice too much deviation from the center reference quadrant.

Viewing Angles

Viewing angles of this monitor are fairly decent for a VA panel – offering up 178/178 viewing angles. Whilst that is the case, you do start to experience some color shift at more obscure angles – a factor that could potentially be problematic when viewing this monitor from afar.

For the most part, however, viewing angles are decent for this panel technology.

Color Gamut

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:

Color Gamut XG43UQ


Looking at the color gamut readings for this monitor, you’d have to say it performed pretty well overall. Comparing our results to ASUS’s specifications, the XG43UQ we received offered greater performance. With a 138.9% sRGB gamut volume – equating to 95.7% Adobe RGB & 98.4% DCI-P3 – the XG43UQ far exceeded the 125% sRGB ASUS marketed.

Color gamut graph XG43UQ

Looking at the physical gamut graph, you can clearly see how far the XG43UQ’s color range exceeds the sRGB spectrum (displayed by the dotted line). Like always, the XG43UQ also falls a little short in the blue area – however, outside of this, it offers a much wider range of 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:

Brightness Candelas
100% Brightness 865.67cd/m²
0% Brightness 96cd/m²
3 Brightness 120 cd/m²
