Connectivity of the Asus PA24AC
We are in the high standards of 2019/2020. It's all there!
What is the worth of the Asus PA24AC display after calibration with the i1Display Pro?
I calibrated this monitor - like all the monitors I test - with the i1Display Pro + i1Profiler software (version 1.8.2) in order to be able to locate this new monitor in relation to the other monitors on the market. You will see that it is not only wide-screen gamut displays (Adobe RGB) that display " right" colors!
Important note ! I plugged this monitor into the Display Port for practical reasons but since there is no difference in color between these three connectors (USB-C, DP and HDMI) - just a question of how much information can flow every second as I explain on my page dedicated to choosing the graphics card and connectors - it doesn't matter. Just a word of advice though: if you choose the HDMI connection, I have been told at least three times that there are problems only due to the poor quality of the cable. So in HDMI, buy yourself a good cable... otherwise, connect it in DP!
I chose the following screen settings:
- Color space (Splendid) : Standard
- Gamma: 90 cd/m2 (screen value: 11/100)
- Contrast: 80%
- Color temperature: 6500K
And as target values in i1Profiler 1.8.2 software in advanced mode...
- Display technology: Choose white diodes,
- D65 or possibly a little less if you want a slightly warmer screen. (Note that at D55, the screen is really hot but not yellow like on the low end screens),
- Luminance: 90 cd/m2 or more depending on your main use (printing or web) and especially the brightness of your room,
- Contrast: Native,
- Gamma: 2,2,
- ADC function disabled,
- ICC standard: V2 to avoid incompatibility problems with some image viewing software (images too dark), especially on Windows 10 and obviously V4 if you know what you are doing.
Make sure to reset the factory settings AND select the generic profile before calibrating! Once the reset is complete, choose the generic screen profile from the system preferences as below on MacOS.
And the result is?
Well, it's a real nice surprise! Amazing even at that price. It is a very correct screen for any photographer who has a tight budget, I can assure you.
Objective data: what does the final report say after calibration?
Before switching to Delta E, it is interesting to record the colour temperature values achieved and the contrast.
My opinion! Achieving a color temperature (CT) of 6452K for 6500K requested is correct and no more on a screen displaying some pretensions but it is not visible in "real" conditions. It's more symbolic than anything else! On the other hand, note - and enjoy! - the contrast of 2600:1. My record (March 2019) on an IPS panel display with a measurement at 90 cd/m2. You will not have any contrast problems with this screen and its blacks are really deep (Only 0.035 cd/m2). Beautiful!
Now, let's move on to the famous Delta E after calibration according to the 2000 standard which I use for the calibration of all the screens on this site:
My opinion! The average Delta E standard 2000 is 0.49 which is obviously excellent! The worst patch (23, a kind of very dark blue-cyan) with a Delta E of 1.85 remains under the bar of 2 so this Asus allows himself to do better than Eizo on his EV2455 (which must use the same panel) it is excellent for an "sRGB" screen. All the other patches are always navigating to 0.50 !
Maintaining uniformity tests in luminance and white point (color temperature):
On the criterion of luminance homogeneity, the Eizo EV2455 does better even if, as visually it seemed very good, I thought the figures would be better. In fact, there is only the lower left corner which slightly exceeds 10% because the rest of the screen is, as the visual impression suggests, quite homogeneous. This is therefore not prohibitive. The panel seems very progressive because you clearly don't see any areas. Finally, as I think the Eizo EV2455 uses the same panel either I had found an excellent serial number or the Eizo electronics makes the difference.
As for the homogeneity of the white point, the values are really very good because no part of the screen shows a color temperature difference greater than a delta e of 2. This is yet another very good point on this display.
Which gamut displays the Asus PA24AC?
As promised, this Asus PA24AC displays 100% of the sRGB.
Note! This measurement was made with the SpyderX Elite sensor, which is also excellent for calibrating this monitor.
