In the following section, we’ll be taking a closer look at the overall color accuracy of this panel. As this is a design-tailored monitor, this section will be particularly important leading up to our final verdict of this product. ASUS says that is has pre-calibrated modes for sRGB, Adobe RGB, and DCI-P3 right out of the box, with all showcasing a <1 average deltaE.
Let’s no forget, the ASUS ProArt PA32UCG does come with its very own colorimeter – meaning, if you do want to increase the accuracy of this monitor, you’ll be able to do so at no additional cost.
We’ll be testing some of the presets to see how accurate they are, alongside panel uniformity, max brightness, color gamut, and text clarity tests.
|Preset||White Point||Black Depth||Contrast Ratio||Average ΔE*00||Gamma|
|Out The Box (Standard Mode)||6586K||0.095 cd/m²||3314.6:1||5.51||2.14|
|Adobe RGB||6576K||0.05 cd/m²||3093.1:1||0.62||2.14|
Before testing any of the pre-calibrated ProArt presets, we ran a quick test right out of the box. We do this with all panels to see how accurate the factory profile is. I could see straight away that the ‘Standard’ preset was on the vibrant side, so accuracy probably wouldn’t be great. As you can see from the chart above, white point was very good as was black depth (0.095 cd/m2). Contrast ratio was well above the recommended 1000:1 and gamma was set to 2.14. The average detalE was the most disappointing value we measured, coming in at 5.51 and being deemed unfit for color-accurate work.
We moved on to the ProArt presets, starting with sRGB. This preset was incredibly accurate right out of the box, showcasing a good 0.9 average deltaE. Gamma was set to 2.14 and white point was very good at 6610K. Black depth reduced substantially in this preset as did contrast ratio. Having said that, it was still well above marketed values.
DCI-P3 was next, with results not being nearly as accurate as the sRGB preset. Whilst white point and black depth were both good, averaged deltaE was the worst recorded – showcasing a 5.93 average. Gamma, like all the other presets, was set to 2.14 and contrast ratio was again, well above the 1000:1 marketed value.
Lastly, we tested the Adobe RGB preset. Again, white point was perfect as was black depth (0.05). Contrast ratio was over 3000:1 and average deltaE was the best recorded, showcasing a 0.62 score which is incredibly accurate. Again, gamma was set to 2.14.
|Preset||White Point||Black Depth||Contrast Ratio||Average ΔE*00||Maximum ΔE*00||Gamma|
|Calibrated Profile||6109K||0.0808 cd/m²”||3811.5:1||0.31||1.99||2.18|
We wasted no time and calibrated the monitor in ‘Standard’ mode to see how accurate we could get the monitor to be. We altered the RGB settings to 54/47/49 and reduced the brightness to 20 for best results.
As you can see from the table above, the calibrated profile offered good colour accuracy that did out-perform the factory-calibrated settings. We recorded a white point of 6100K alongside a 0.08 black depth – not unusual for IPS calibration. Contrat ratio almost hit 4000:1 and average deltaE dropped to an impressive 0.31 – with a max of 1.99. Gamma was now reading 2.18.
Panel uniformity is a test we run to check how uniform the luminance and colors are 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.
Overall, the panel uniformity for this display was very hit and miss. As you can see from the graph above, whilst only 1 quadrant recorded a ‘red’ score, large portions of it came back as amber – only just passing what is considered the nominal tolerance levels.
So, whilst this display wasn’t the best we’ve ever tested, it was by no means the worst either.
As expected from an IPS panel, the ASUS ProArt PA32UCG offered very good viewing angles – 178/178. The large screen meant that you could easily view this from wide angles and still get a perfectly good view of the panel.
Having said that, with excellent stand versatility, I can really envisage a scenario where you might need these viewing angles.
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:
As far as color gamuts go, the ASUS ProArt PA32UCG offered one of the widest we’ve ever tested. It easily covered 100% sRGB and 100% Adobe RGB – providing a gamut volume of 187.4% and 129.1% respectively.
Whilst the monitor did showcase a large gamut within the DCI-P3 spectrum (132.7% volume), it was still the least in terms of percentage coverage – only offering 94.7%.
Maximum And Minimum Brightness
We ended the color accuracy and picture quality testing by checking the maximum brightness, minimum brightness, and 120 candelas level on this panel. The results are below:
|100% Brightness||434.21 cd/m²|
|0% Brightness||9.4 cd/m²|
|19 Brightness||120 cd/m²|
