Electronics supermarkets for general audiences are offering calibration of TVs as an option now, and some gaming monitors will even bring along an individual calibration chart.This is part 4 of our color monitoring series (it started here).

TV and cinema

Well, according to our recent measurements, the decently priced ProArt models by Asus can suffice for Rec. 709 and even some more. We were quite surprised finding a wide QHD gaming monitor by Xiaomi also coming with a chart and meeting the specs when checked with our probes and software. But then, this all applies to screens which can meet Rec. 709 without much effort. While professional grading for cinema in DCI P3 would normally be done in a dark room with a calibrated projector, what about grading for HDR? 

Well, let’s first get some misconceptions out of the way, since most of the marketing stuff is confusing things (intentionally?). DCI P3 would be the standard for cinema, as explained above. It expects a gamma of 2,6, but only 48 nits for white – after all, it’s for a dark environment and a very large screen. You may not even notice in cinema that it has a white point around 6.300 K, which is better suited to Xenon lamps. You would not really like to watch that it in a living room or, even worse, outdoors. 

So, Apple created a thing now called Display P3. This has never really been standardised, but has been adopted by others, mainly for phones and tablets. So, a majority out there might be able to watch video like that now instead of the older Rec. 709 for TV. The white point is 6.500, standard white is 120 nit, and gamma is 2.2. The only thing it has in common with cinema is the wider color space of P3. While Rec. 709 (or sRGB) is only covering about one third of human vision for color (as defined by CIE 1931), P3 is doing more than half. And Rec. 2020?

Rec. 2020, a standard for the future

The color space for HDR TV in the foreseeable future is defined by Rec. 2020. It would cover 75% of human vision for colors, but very few technologies of today can reproduce it. RGB pure laser projectors can achieve up to 98% of the Rec. 2020 color space, and one from Christie will cost you only 84.000 € (plus tax and lens). It will eat 1.800 watts of power and resolve HD natively, but simulate more by pixel-shift (see more here at Christie’s).

Oh, and one of those is normally used for presentations in special venues, like theme parks, projection mapping, IMAX, and impressive exhibitions, not in your average local cinema. Anyway, some cinemas are going for them now for attraction and future proofing. If we are trying to get more realistic, we will look at ordinary monitors, the best of which may cover 86% of that color space. 

Technologies to get there as of today are WOLED, QD-OLED and mini-LED, to which Apple recently added Tandem-LED in the iPad Pro – as usual, without telling us the exact percentage of Rec. 2020 achieved. For some realism, read this. BTW, even a huge QD-LED based reference monitor from Flanders Scientific, a manufacturer respected by professional colorists, the XMP551, will cost you around 20.000 € and covers ‚only‘ 90% of Rec. 2020 color gamut.

What about HDR?

HDR, though, is mainly about contrast. Generally, you could increase contrast by stronger highlights, which is driving up power consumption and heat, or by deeper blacks. OLED is one of the technologies getting pitch black, other than conventional LCD screens. It also has very wide viewing angles without any image degradation. Unfortunately, OLED has a hard time with very high brightness, which may ruin it quickly without protective measures. What’s on the market right now?

Flanders XMP310 and XMP270 both can handle 1.000 nit for Dolby Vision, which is only one of the competing standards, and reach ’only’ 80% of the 2020 color gamut. But even these are well beyond 10.000 €. Apple claims 1.600 nit for their XDR screens. While these are still expensive in larger sizes, they come for less in mobile devices. But all such maximum values are for local highlights. If it would show that full screen, the poor thing would go up in flames. 

So, to protect the OLED, all of such displays use an ABL (auto brightness limiter), just like LG OLED TVs, which are also popular with pro colorists. In consequence, all of them will be able to show highlights to a varying degree of brightness, but only in a limited area. Even the expensive Flanders have ABL, and you can only switch that off by going deep into hidden service menus and ruining your warranty. Ouch! 

For any such screen, the maximum brightness achieved will be related to the percentage of screen estate that highlights are covering, and normally there’s even a difference between peak values displayed for a short time and sustained ones. Of course, any decent screen will sustain more than 120 nits on the whole screen, so it should not be a surprise if we calibrate to 120 even for HDR. What comes as a bad surprise are changes in the whole scene when ABL kicks in. So, what to choose?

We may see Apples Tandem-LED screens in future MacBooks, but I doubt any time soon in larger monitors. Under the current iPadOS you can can’t calibrate an iPad. In the end, we had a closer look at an OLED screen for gamers, the Asus PG27AQDP. It comes calibrated for SDR with an individual chart from the factory. Getting up to 600 nit and covering P3 would already give you a decent HDR look with perfect blacks. It’s not a QD-OLED, but didn’t I start with the slogan „Color Grading for Cheapskates“?

Measuring an OLED monitor

At first view, it’s very obviously targeted at hardcore gaming, being part of the „ROG“ (republic of gamers) product family. The headline we cited above also aims at that community. Nevertheless, it comes with an individual chart, surprisingly made for Rec. 709 (actually, sRGB), with a gamma of 2,24 and an average color accuracy of 1,37 Delta-E, not exceeding 2,1. It carries the DisplayHDR True Black 400 label, which is an independent label by VESA, even if the lowest level (screens with higher ones are considerably more expensive). For details, see here.

Of course, we did not want to trust just the chart or label alone, and also see what we get for the newer standards. Older probes like our trusted Color Munki or X-rite (see here) can’t handle OLEDs correctly. If you’d try the approach described in my other articles, you’d be disappointed. At first view, the values look really bad. That’s not a limitation of the screen, but those older probes are not ready for recent technologies. 

This time, we got a Spyder Pro by Datacolor (more about it in another article), which is capable of taking on OLED and very wide gamut, and handling up to 2000 nits. It is not recognised by DisplayCal, so we used the Software coming with the probe, aptly named SpyderPro, in version 6.2.

Adjustments

The software is pretty easy to operate and fast. As described in our articles linked above, one should first try to get the screen as close to specs as possible with its internal adjustments. While the color adjustments didn’t help much, at least you can turn down the brightness to the levels needed according to standards.

But we observed a strange phenomenon here: brightness always went up a bit when leaving the OSD. So, you’ll need a bit of fiddling to get it right, we ended up with a value of 42 in the OSD (for HDTV). There might be some ABL switching on and off even at these levels.

Another confusion resulted when checking the gamma: while the OSD is offering choices of gamma values, it’s always far too high, according to the Spyder Pro. We needed the lowest setting of 1.8 to meet the standard for web at 2.2, and the next value to get 2.4 for proper BT. 1886. These deviations may be corrected by Asus with firmware upgrades, but their installer didn’t work for us.

Since we didn’t get any better results from trying to adjust colors, we decided to try the presets offered by the monitor’s menu. BTW, all of these adjustments are available in performance mode only, in energy saving mode you’ll be stuck in gaming settings, for whatever reason. 

Results

Once we got brightness and gamma right, the results were not bad at all. Rec. 709 is fully covered, and P3 to 96%, which you’d hard pressed to tell from 100% visually. Rec. 2020 colours are covered to 71%, but check above how much you’d pay even to get 80. For the time being, stick to P3 for HDR. Brightness peaks close to 1.200 nits, but only for a tiny area of 2% of the screen. 

For comparison: Apple doesn’t tell us how much their Liquid XDR with Mini-LEDs in the recent MacBook Pro can cover at 1.600. While Rtings measured less than 1.500 for 2%, it can sustain close to 1.200 even for the full screen. The color gamut is full P3 and close to 73% of Rec. 2020 ( see here). Its only weakness is some blooming, and, of course, the size.

Nevertheless, you can get over 600 for 10% of the Asus screen, which is decent for practical work in HDR. Contrast ratio is, of course, kind of infinite, since black is black. One big advantage over Mini-LEDs is the absence of blooming. The screen offers detailed features to fight burn-in, the achilles heel of OLED. This may be even more important than for games if you have one single GUI like DaVinci Resolve on the screen all day long. Asus says they are using a custom heatsink to get such bright highlights.

The software by Datacolor comes with a separate app for analysis of a screens quality, called Spyder MQA. Compared to factory calibration by Asus, most of the skin tones and lighter gray values got improved by the Spyder’s calibration, while one dark cyan (1F) suffered, even into slightly visible deviation. All other patches stayed under 3 or only a tiny bit over, with an average close to 2.

Datacolor explained this one deviation at 1F by the difficulty to calibrate a monitor with very wide native colors to Rec. 709 or even P3. Without a high-end probe around, we can’t verify this, but it seems plausible. If trade-offs are unavoidable, it makes perfect sense to go for good skin tones and a neutral greyscale. While some uniformity issues for brightness are normal at this price level, color uniformity is excellent, being under 2 Delta-E at 100% brightness.

Handling

Mechanics of the PG27AQDP leave a few points to be desired. Proper horizontal alignment is difficult to find, there is no fixed position for it and the adjustment shows a lot of friction. The height adjustment simply didn’t hold for us, always returning to the top position. Reviewing only one sample, we can’t tell if this is a problem with our unit only, but I’d assume it is. 

And then, the support with its three legs is prone to let it fall off the table when there is no wall behind and it’s pushed back too far. The ProArt PA279CV doesn’t have such issues and is coming with a heavy, rectangular plate. While the gaming screen looks stylish, you ask yourself how it gained two design awards – form follows function doesn’t matter any more? Even gamers complain about the space blocked by those legs in the front.

Service

The chatbot for support is not the brightest candle, a very specific question about a ProArt PA279CV being compatible with Asus’ Display Widget Center was answered with standard marketing information, not meeting the point. But you may download very detailed manuals as PDF in several languages. Our experience with their serve center in Germany when needing repair for a ProArt PA279CV about two years old with broken backlight was excellent. No, we didn’t inform them about reviewing it, but appeared as a regular private user.

Recommendation

While you can’t get the PG27AQDP for the price of a Xiaomi G34WQi or an Asus ProArt PA279CV, which are decent for SDR, it is one of the best low-cost options for HDR. Small highlights pop in HDR, but aggressive ABL can kick in. For those who also need to grade for SDR, it’s also fine with a separate calibration. 

If you are not into hardcore gaming too, you can get the very similar Asus XG27AQDMG with a lower refresh rate for less. It’s also VESA HDR 400 approved, but glossy. So, the choice also depends on your environment, since the PG27AQDP is matte and has a bit less punch. Definitely look for that minimum VESA label, including the True Black notion, since everybody is calling their screens HDR these days, without any proper justification.

We also had an issue with fine text. It is a bit rough and less readable than on the Xiaomi G34WQi, which has the same vertical resolution. A different sub pixel layout seems to be the cause. But that doesn’t matter if you use it strictly for monitoring your final video and have another monitor for the GUI, where many prefer a wider screen anyway.

TL:DR: 5K is great if you want to have a lot of stuff on your screen, and the screen excels on displaying pure information, and otherwise is a solid companion to your main broadcast monitor.

---

The standout feature of the ASUS ProArt Display 5K PA27JCV is its 5K resolution (5120 x 2880 pixels). For most (but not all) work, the difference between 4K and 5K at typical (!) viewing distances can be negligible, especially when working with compressed or lower-resolution content. Scaling footage to 5K often leads to a loss of sharpness, with the added pixels not providing a noticeable improvement.

But isn’t bigger better?

Where 5K does make a significant difference is in non-video/color tasks, such as using the monitor as a secondary display for software interfaces. The clarity provided by 5K resolution is quite nice when managing complex tool-sets and windows, making this monitor ideal for professionals who rely on precise visual organization. So, if you squint at your node-tree, scroll for ages through settings, or can’t see the bottom of the To-Do-List, 5K (Especially when running it in portrait) is very nice indeed. Well, not when the To-Do-List is this long, but you know what I mean.

Pixel Density and Color Accuracy

The ProArt PA27JCV offers an impressive pixel density of 210 PPI, more than 2.5 times that of a typical 27-inch Full HD display. In terms of color accuracy, the PA27JCV covers 99% of the DCI-P3 color space, which is more than enough for content creators needing reliable colors. We measured a Delta-E below 2 (Again, the edge of what we are actually confident of saying with the available Colorimeters). That means, if you want to watch some of your footage, or have the Media Browser / Library on that screen, you will not have any problems, judging which Shots, Takes or Renders are best.

Tech Specs

The 27-inch IPS panel features 5120 x 2880 resolution with a 218 PPI density. It offers 100% sRGB, 95% Adobe RGB, and 99% DCI-P3 color accuracy. The monitor delivers 400 cd/m² typical brightness, 500 cd/m² peak HDR, and supports HDR10 with 10-bit color depth. It has USB-C connectivity with Power Delivery, and adjustable tilt, height, and pivot. VESA DisplayHDR 500 and TÜV Low Blue Light certification ensure a comfortable viewing experience. For more details, visit the ASUS ProArt Display PA27JCV Tech Specs.

One additional thing, because I personally think all company should be commended for the efforts: The packaging is almost completely plastic free, recyclable, no Styrofoam, and can be reused in some ways, or, give it to your cat – if we didn’t have to send the sample back, the editorial floof would have claimed that box.

Adaptive Color and Brightness: Pros and Cons for Color Grading

The ProArt PA27JCV features adaptive brightness and color adjustments, which automatically adjust to ambient lighting conditions. While this is useful for office work or as a secondary display, it can interfere with color-critical tasks like color grading. For professionals who require precise color accuracy, these dynamic adjustments can distort colors. Thankfully, these adaptive features can be disabled, allowing users to manually control brightness and color temperature. The settings are comprehensive, and there are many , many parameters to tweak – Adaptive light AND a sensor for background keep the screen “in the sweet spot” all day long, no matter how bright/dark the weather is outside, and no matter which of your fellow artists works under a spotlight or is going full troglodyte. Basically: The second screen in your setup gets “out of the way” and just does what it told.

But there is a backside to that: If you don’t realize there are two systems for light, and you use it as main monitor, you will either have to turn of both, or, if you didn’t read the manual with full concentration (Not that this has happened to me, ever….*cough*) you’ll think something is seriously wrong when the screen cycles into the measured area.

Brightness and HDR: Comfort and Clarity for Extended Sessions

While not the brightest monitor, the ProArt PA27JCV strikes a balance between vibrant and comfortable brightness. With VESA DisplayHDR 500 certification, it produces deep blacks and bright whites, delivering excellent contrast for professional workflows. The monitor’s peak brightness is sufficient for most tasks, providing a vibrant viewing experience without straining your eyes during extended use.

But one thing is “spot on”: The anti-glare. Asus has hit the sweet spot between “no reflections” and “crisp colors”, making the PA27 a workhorse , even in difficult “environmental situations”. Keeping with the theme of the Second screen: You can place it where it is convenient, and don’t have to worry about light-treating your environment. And, comparing to another Screen with 5K, proper Antiglare is a gamechanger – not to mention about half the price, and you get a stand included in the price.

---

Connectivity

The screen comes with a built-in KVM (Which we did’t test, because currently there is only one workstation around), as well as 2 HDMI 2.1, a Display Port 1.4, an USB-C (with 96 Watt Power Delivery, Displaysignal, Data and Audio, making it a single connection to your mobile Workstation), as well as a Usb-Hub with two easy to reach ports in the left corner of the screen, one USB-C and One USB-A, and last but not least, a headphone jack, if you are “hotdesking” (I don’t know if that is a verb these days…) So, that is solid and has everything you need in a Multi-Monitor Setup.

Additional thoughts after 2 Months of testing …

Since I had this screen on my desk, let me tell you a few notes – I ran it in Portrait mode, which is such a relief with the extra resolution – no more scrolling in many things and with the excellent anti-glare, the window opposite the screen does not bother me at all.

While talking about placement: The Vesa-Mount is solid and to spec, but Asus made the “Shell” around it quite tight – if you have a “bigger mount”, that might require some wiggling.

And one other thing: Since I was running it in Portrait, usually you see the “Angle” Problems with both brightness and color. Even if IPS-Panels in this case are better than TN-Panels, usually there is some “tradeoff” – but in all this time of testing, I haven’t noticed it – you have to actually look for the problem, otherwise it will not impact your daily work.

Pricing and Value: Who Should Invest?

Well, so, this means, we are the point where we ask: Should you get one?

Before considering that, there is a caveat: When you are working with the Adobe Suite, you might consider the three-month-promotion, which this screen is eligible for – so, register in the “MyAsusApp”, then click through Redeem and put in your serial number, and choose which Adobe thing you want. That lowers the actual price for the screen. If you aren’t working with the adobe tools, then… well, forget what I just said.

So, what do you have to pay for this product? The current price is around 940€, which is not cheap, but not absurd either – considering that ASUS Screens keep and are solid work machines. But, as is the development in this day and age, the street price will come down – Amazon lists the screen for 900€, and we have seen offerings around the 800€ mark – which make the screen maybe not a “steal”, but a solid offering for everybody who can’t take a 1440p – Interface anymore.

For all those die-hard Mac users, who enjoyed 5K with the old Intel iMac and are still waiting for a 27“ iMac with Apple silicon, this is good news. After all, the 5K LG (with the same panel) is not available any more, and Apple is still asking Apple prices for their screen. So, if you don’t desperately need a stylish all-in-one aluminum gadget, a tiny aluminum gadget called Mac mini Pro and this Asus model should please your eyes and your purse.

(Remark by Uli Plank, who is already slightly tippsy
around 9 p.m. after one or two Japanese Highballs
in SE-Asia, but still longing for his 2017 iMac’s screen.)

Conclusion: Best for Interface Work

The ASUS ProArt Display 5K PA27JCV excels as a high-resolution monitor for managing complex software interfaces. Its sharpness and color accuracy make it a valuable tool for professionals who need clarity and precision in their workflow. However, for tasks involving color grading, the monitor’s adaptive features and 5K resolution may not be as advantageous as they seem.

Ultimately, this monitor is best suited for professionals who need a reliable secondary screen or a sharp display for design work—not necessarily for color-critical video post-production, but as a very, very good GUI-monitor. Who would have thought that screens would diversify to a point like this!
