Asus PA24AC monitor review


Asus ProArt PA24AC monitor review

Published on March 26, 2019   |   Updated on May 10, 2020

Facing the Eizo EV2455 screen, Asus responds with a panel very close in terms of color display accuracy but with less uniformity. It makes up for it with its superb finish and... the price. So you will have a choice!

Not everyone needs a so-called wide gamut screen displaying the Adobe RGB. On the contrary, I would even be tempted to say. sRGB is indeed the colorimetric space of the Internet (in short), even in 2020. But many of us provide content to this ogre! The Asus PA24AC is therefore interesting for more than one reason. Unlike the Dell P2419H which I recommend at less than $200, this Asus displays colors with very high accuracy. For some, this may make a difference even if it costs twice as much. The Dell, on the other hand, can be perfectly suited as a secondary display in a dual screen configuration.



In a few words...


Asus PA24AC


Here is my favorite monitor 2019/2020 at $329 displaying the sRGB. Certainly the homogeneity is not perfect but the precision of the colours is remarkable, as is the finish or the state-of-the-art connectivity - Read my conclusion

Important note! Asus displays do not have a built-in colorimeter

This Asus PA24AC does not have an integrated colorimeter so you will need to use your sensor or buy one.

My buying advice : i1Display Studio or the SpyderX PRO

The monitor and its panel

1 - Definition/resolution - This matte IPS panel displays the "classic" Full HD 1920 x 1200 ! Its resolution is therefore 94 ppi. It is therefore not a "Retina" screen but the micro-contrast offers a very high sharpness, above average. The images will be shot on this screen! In addition, any graphics card will do.

2 - The panel and its anti-reflective coating - Its panel, obviously matt for any self-respecting photographer, has an anti-reflective coating in the high standards of 2019/2020. Nothing to complain about.

Thickness of the screen edges

Ultra-thin - 5 mm - they allow you to easily integrate your displays in a multi-screen configuration

Ergonomics makes a few impasses in terms of finishing. It's never really embarrassing, but some Dell displays do better. For example, it is certainly possible to raise or lower the panel by more than 110 mm but not as high as at Dell or Eizo. Another example is that there are no cable bushings. On the other hand, the standard for wall mounting is the classic VESA 100 mm.

The buttons on the screen menus

The keys of the monitor menu are hidden behind the screen and you will also find an original cursor (photos below). This cursor is clickable and especially multidirectional. I say original because it's the first time I've seen this type of setting button on a screen. In practice, I found it really almost awesome because it's fast and there's no need to look for the cursor that allows you to go up and down!

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.


Final report after the calibration of the Asus PA24AC with the i1Display pro


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:


Delta e after calibrating the Asus PA24AC with the i1Display Pro


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):


Luminance uniformity after calibration of the Asus PA24AC with the i1Display pro


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.


And my subjective data: what does my eye see?

At the first display and even more so after calibrating it with my two favorite colorimeters, I liked this display. The blacks are deep, the contrast really pleasant, especially when surfing the Internet, and the images are very sharp in Photoshop. It is therefore a favorite around $400 for those and they are many in my opinion who have more interest in choosing an "sRGB" monitor rather than an "Adobe RGB" one.




  Asus PA24AC  
Color fidelity 9,0/10
Uniformity of the panel 8,5/10
Resolution 8,0/10
Ergonomic design 9,0/10
Inputs 10/10
Manufacturing quality 9,5/10
Value for money 9,0/10
  I like it very much...  
  • A very nice and good sRGB screen around $400!
  • Matt IPS panel,
  • Incredible contrast: 2600: 1 measured at 90 cd/m2!
  • HDMI + Display Port + USB-C,
  • Very nice finish,
  • Calibrates very well with all recent sensors on the market,
  • Very thin edges for multi-screens.
  • VESA 100mm,
  • A great value for money for those who are looking for precise colours, in sRGB, with a controlled budget.
  What I regret...  
  • Maximum height adjustment a little short,
  • Homogeneity of my test copy not perfect but I almost falter,
  • "Only" sRGB but is that really a problem?
  • Very little at this price in the end!
  My overall rating...  
  9,0 / 10, My favorite in sRGB!  
  My conclusion...  

More and more of us only work on the Internet so I think an sRGB display is a good choice. There's no point in having a counter that goes 300 km if you stay in Paris! Well for those who are convinced by my arguments, I think I have found a very good monitor for a still reasonable amount of money and especially without major defects. A real favorite for this monitor full of contrast, display finesse and really precise colors.

An Alternative that seems to use the same panel for those who "want" a recognized brand... but significantly more expensive and better only in uniformity on my test copy: the Eizo EV2455
