ASUS ROG SWIFT PG32UQX review 2021


Great colors and picture quality are two of the main factors that help keep you immersive as you play. Despite the importance of good colors, monitor manufacturers do not always calibrate the color of their panels to what is considered accurate within certain color spectra – for example sRGB / Rec. 709.

We like to test every monitor for color reproduction to see how it performs 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

We started the color accuracy performance section by pre-testing the XG43UQ right out of the box. The “Racing mode” preset has been installed for this monitor, which sets the brightness to 254 candela – more than the recommended brightness for everyday use.

The XG43UQ’s colors in the out-the-box settings weren’t terrible by any means. Granted, they weren’t the best we’ve seen – but they weren’t the worst either. We have a white balance of 6090K (a little below IDEAL) and a decent black depth of 0.0294 cd / m². The contrast ratio was higher than the rated 4000: 1 (4171: 1) and the gamma was set to 2.21. The average deltaE was 2.62, which makes the RACING mode preset for color accuracy OK – but not amazing.

I wasted no time uploading the sRGB preset to see if the monitor was pre-calibrated to a deltaE of cd / m²). The contrast ratio decreased slightly (3782: 1), while the gamma remained stable at 2.25. Most impressive, however, was the average deltaE of 0.98. While it wasn’t the 0.85 that ASUS put in their color calibration review, it was close enough.

There were a ton of other presets in the monitor’s OSD, but few offered accuracy close to the sRGB spectrum. That said, we made some notes about the preset, which are listed below:

Landscape – The landscape mode offers more vibrancy and a gamma-richer viewing experience. With this setting, the brightness is definitely increased and pushed above the recommended threshold of 120 candela.

Movie theater – Cinema mode gives the XG43UQ a bluish hue that is definitely noticeable compared to other presets in the monitor’s GameVisual arsenal.

RTS / RPG mode –This preset offers a profile similar to sRGB. The colors feel balanced, with orange / red colors standing out.

MOBA – Moba was the worst preset I tested as it blurs a lot of the colors and makes it look almost black and white.

After testing the various presets, I wasted no time and decided to calibrate the panel – to record the color space, panel uniformity, and overall color accuracy.

I selected the ‘User’ settings for calibration and changed the RGB values ​​to changing 96/96/100.

Here are the results:

After the calibration, we were able to significantly reduce the average deltaE overall. The white balance stayed constant at around 6500K, as did the depth of black (0.0295). The contrast ratio decreased slightly to 3905: 1, while gamma gave a value of 2.22. The average DeltaE after calibration is 0.37 – an increase in accuracy of about 62%. Nevertheless, we still achieve a maximum deltaE of 2.06 – somewhat disappointing, but quite acceptable for color-accurate work in the sRGB spectrum.

Overall, the XG43UQ’s color accuracy was quite decent. I can easily recommend this monitor for gamers who like to play different titles and need a good sRGB preset for color-accurate work.

Uniformity of the panel

Panel Uniformity is a test we run to see how even the luminance and color is across the entire screen. In this test, the middle square is used as the reference space. Every other square is then tested to see how far it differs from the reference.

In an ideal world, we want every square to be green, that is, it hasn’t crossed the difference threshold – something we can establish at the beginning of the test.

Note: The results differ from panel to panel.

The panel evenness for this display was surprisingly good, with both the average DeltaE and luminance offering decent scores across the board. As you can see from the graphic above, the left side of the monitor offers the worst evenness. With a yellow value, however, you will not notice that the deviation from the mean reference quadrant is too great.

Viewing angle

The viewing angles of this monitor are quite decent for a VA panel – with up to 178/178 viewing angles. While this is the case, there are some color shifts at darker angles – a factor that could potentially be problematic when viewing this monitor from a distance.

For this panel technology, however, the viewing angles are mostly decent.

Color space

As part of the calibration process, DisplayCal provides an accurate measure of the color space that the monitor can provide. The results of the color space test are as follows:

Color space XG43UQ

If you look at the color space values ​​for this monitor, it has to be said that it did pretty well overall. If you compare our results to ASUS specifications, the XG43UQ we received performed better. With a 138.9% sRGB color space volume – this corresponds to 95.7% Adobe RGB and 98.4% DCI-P3 – the XG43UQ far surpassed the 125% sRGB marketed by ASUS.

Color space diagram XG43UQ

If you look at the physical gamut diagram, you can clearly see how far the color space of the XG43UQ exceeds the sRGB spectrum (shown by the dashed line). As always, the XG43UQ also cuts a little too short in the blue area, but it also offers a much broader color palette.

Maximum and minimum brightness

We finished the color accuracy and image quality test by checking the maximum brightness, minimum brightness, and 120 candela points on this panel. The results are below:

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