Asus ProArt PA279CV 27inch 4K UHD HDR Professional IPS Monitor

So, I bought this during the first 2022 black friday sale, after seeing and reading a lot of positive reviews.I work as a freelance videographer and editor and this monitor is fantastic for colour accuracy, everything pops very nicely.I have it paired with my Dell Ultrasharp U2723QE, and while they both have 100% sRGB and Rec. 709 colour spaces, it was a little difficult to match them. But, I feel I have them close enough that it makes very little difference when colour grading.I've also used it for gaming and it looks great! Mind you, I really only play games like Dark Souls and don't play any competitive shooters that are advantaged by higher refresh rate monitors, so I haven't had any issue with it being 60Hz; 60fps is fine for me!Overall, I highly ... MoreSo, I bought this during the first 2022 black friday sale, after seeing and reading a lot of positive reviews.I work as a freelance videographer and editor and this monitor is fantastic for colour accuracy, everything pops very nicely.I have it paired with my Dell Ultrasharp U2723QE, and while they both have 100% sRGB and Rec. 709 colour spaces, it was a little difficult to match them.

A 4k "Prosumer" Dream

If you're looking at this ASUS ProArt monitor, you're likely a graphics professional or someone otherwise interested in high-quality, color-accurate displays. As someone who does a modest amount of graphics work and is very sensitive to display quality, I can say I am highly satisfied with this monitor and count it as likely the best I've used in my personal or professional life.First off, this ASUS offers full 4k 60 hertz resolution at a nice 27-inch size. Having been used to a 24-inch 1080p display I can say the switch to 4k was immediately noticeable. It's akin to going from an old Android phone to the latest iPhone -- you no longer see the pixels in the display at your typical seating distance, and everything is rendered crisply. This ASUS offers a display ... MoreIf you're looking at this ASUS ProArt monitor, you're likely a graphics professional or someone otherwise interested in high-quality, color-accurate displays.

Having been used to a 24-inch 1080p display I can say the switch to 4k was immediately noticeable. It's akin to going from an old Android phone to the latest iPhone -- you no longer see the pixels in the display at your typical seating distance, and everything is rendered crisply. This ASUS offers a display experience in line with what most modern smart phones and tablets, as well as high-end laptops, offer. If you haven't yet used a 4k display the difference really is something to experience, and going back to a non-4k display is pretty tough!I am driving this display with a 13-inch Surface Book 2 and a Surface Dock 2 and have had no issues with full 4k resolution at 60 hertz via a USB-C connection. You'll want to make sure your computer and/or docking solution are capable of driving high-resolution displays like this one, but I'm fairly confident most computers and even tablets from the past few years should have no trouble.The "ProArt" designation of this model clearly targets it at the "prosumer" level, and ASUS packs in plenty of pro-level goodies to satisfy you. Here are some highlights:First, the connections. The ASUS includes two HDMI ports, a DisplayPort and a USB-C port, giving you maximum flexibility and compatibility, especially if you want to connect multiple machines to one display. All these ports are capable of accepting both video and audio, as the ASUS includes built-in speakers. The sound quality isn't much to write home about, but it's entirely acceptable for Zoom calls, which is all I need it for in my setup.In addition to the aforementioned ports, the ASUS includes four USB-A ports and a headphone jack. You'll need to connect to the monitor with USB-C to enable the auxiliary USB ports. I did this and connected my webcam to one of the ports and everything works as expected.Connecting via USB-C offers one additional benefit: The ASUS can supply up to 65W to your computer via the USB-C Power Delivery standard. This is plenty for many tablets and laptops, but you'll need to check your specific device's needs. My Surface Book requires over 100W, meaning it'll charge slowly or not at all via this connection, depending on how intensively I'm using it. However, if your device doesn't need as much power as mine, you might have a true "one-cable" connection with this monitor. Definitely check to see how many watts your device draws if you're hoping to use the ASUS as both monitor and hub; regardless of power needs, the USB-C connection does offer simplicity and future-proofing.Next up in the ProArt highlights is the build quality and adjustability. This ASUS is well-built, with a nicely-weighted stand included. Even heavy typers like me shouldn't notice any side-to-side wobbling. Even better, the included stand allows you to rotate the screen side-to-side, move it up and down, change the angle and even rotate it 180 degrees for reading long documents or other uses. I'm really pleased with the overall build quality and appearance. The ASUS offers black and dark-ish gray accents and is attractive without being flashy. You may notice the display itself is thicker/deeper than some others, but that's because of all the ports and the built-in power supply. This means you get a standard three-prong power cord, rather than the cord/power brick combo that many other monitors use. I vastly prefer the standard power cord of this ASUS to the cord/brick setup. It's neater overall and allows you to swap out the power cord easily for a longer one if needed. Even better, ASUS includes a power switch on the back of the monitor that kills power to the entire device, in addition to the regular power button on the front that puts the display into a very low power draw "off" mode.Finally, let's talk about the picture quality. In short, it's both excellent out of the box and highly-customizable. A big reason for choosing a ProArt-branded model is the certified factory calibration of the display, which is CalMan Verified -- basically, you're getting nearly-perfect color reproduction from day one without any extra work on your part, though it's a little more complex than that.First, the CalMan Verification is only for two of the monitor's color modes: sRGB and Rec. 709. If you know what those are and work primarily in one of those two modes, you're calibrated and good to go. The ASUS offers multiple color modes in addition to these, but they're not CalMan Verified. Switching between modes is done using the OSD menu system and buttons on the front, or by installing ASUS' ProArt Chroma Tune applet. This runs in the background of Windows and lets you change color modes via the right-click menu or set up automatic mode-switching when you launch certain apps, like Adobe InDesign.I'm far from an expert, but I can tell you the sRGB preset is both a widely-used display standard and factory-calibrated, making it the best bet for most. I found a big step down in brightness from the Standard preset, and there are no adjustments to brightness allowed when using the sRGB preset. I find it just a little too dim for everyday use myself, but your mileage may vary. Colors seem plenty accurate in the Standard preset and the brightness is fully adjustable here, so that might be a good compromise for most uses except highly color-sensitive work.I won't run through each preset, but suffice it to say, there are plenty of options. This ProArt model allows for a wide range of customizations in addition to the presets, and you can save two presets for yourself once you dial in your preferred settings. Anyone looking for a highly-customizable display should find what they need here, but again, you'll want to explore the full specifications to make sure the ProArt can accommodate you -- and I'm guessing it can. I personally find myself bouncing between the Standard and sRGB presets depending on what I'm doing.This thing gets plenty bright, so much so that on the Standard mode's 50% brightness default, a screen that's mostly white is far too bright in my modestly-lit home environment. Certainly the ASUS should get bright enough for any home or office environment and I'd wager a guess that even direct light from behind won't wash things out too much if you crank the backlight. Again, the ability to customize things to your needs makes a big difference.In addition to the presets the display and full control over color, brightness, contrast etc. in the OSD menu, the ASUS offers a blue light filter and picture-in-picture modes, on-screen guides for standard document sizes, adaptive sync refresh controls and more. Suffice it to say, you can probably find a mode or setting for just about anything.I'll highlight one final mode: HDR. The ASUS supports HDR10 content and I successfully enabled Windows 10 full color/HDR mode. I found the picture excellent by my sensitive but untrained eyes, however I noticed animations were a little slow in HDR mode (things like scrolling or minimizing ap windows), even running at a full 60 hz, so I turned HDR off. If you're someone that wants to use this as a way to stream Netflix you might find HDR to your liking, but again, your situation may vary.In conclusion, this is an excellent factory-calibrated 4k display with enough customization to last a lifetime. It easily blows most consumer-oriented models out of the water and should meet the needs of many discerning graphics-oriented professionals. Those looking for pro-level connections and settings should be satisfied, but I encourage you to read through all of ASUS' product information before making your final decision. This ASUS easily satisfies my high-end consumer/prosumer needs, and I look forward to using it for years to come.

A beautiful display, with some caveats

The Asus 27" IPS 4K ProArt Monitor is one of the most color-accurate and brilliant displays I have ever witnessed and it lives up to its promise in delivering a quality of picture seeked by graphics designer amateurs and professionals alike. It's well made, has plenty of connectivity options and offers several features to ensure you are seeing exactly what you should be seeing when working with digital media. It's 27-inch diagonal screen size and resolution support up to 4K at 60Hz refresh rate will satisfy the target demographic of whom these monitors were made for, so if you're looking to use this display for higher frame rate activities, such as gaming, you may want to look at Asus other line of gaming monitors, from the likes of TUF Gaming and Republic of Gamers ... MoreThe Asus 27" IPS 4K ProArt Monitor is one of the most color-accurate and brilliant displays I have ever witnessed and it lives up to its promise in delivering a quality of picture seeked by graphics designer amateurs and professionals alike.

You do not have support for DVI/VGA however, so keep that in mind if you're needing to connect the monitor to an older graphics card or computer.I am using HDMI for my setup, and I would rather prefer using DisplayPort like I already do on my other monitor... however, this is where the problem begins. Because of the way DisplayPort works with "hot plugging", when my computer goes into a sleep state, it tends to keep this monitor's LED backlight powered on while my other monitor is completely in standby mode. None of the options or settings in the monitor's menu or on my computer's Windows settings or graphics card settings was able to remedy this issue, my only other choice was to plug it in using HDMI while keeping my other display using DisplayPort to allow it to fully go into standby mode when locking my computer or putting it to sleep. While this may not seem like an issue in the short-term, it's probably important to preserve the lifespan of your monitor's LED backlight and ensure it's only on when it needs to be. That's just my two cents on that, but if such a nuisance isn't a problem for you, then you can happily connect two or more displays using DisplayPort to your liking.So, besides that minor issue with this monitor staying on when my computer goes into sleep mode, and the refresh rate being limited to 60Hz when I don't see why it can be higher, especially on resolutions lower than 4K, this monitor is a fantastic choice for all other uses and most especially graphics design. It was pretty interesting to see that the monitor had it's own calibration certification out of the box and was thoroughly tested to ensure a color-accurate picture in the factory prior to packaging.In the end, you can't go wrong with the Asus ProArt 4K display, but what's keeping me from giving it a true 5 star rating is the issue with the display not entering a low-power/standby state when my machine is clearly in a locked state or in sleep mode. It also doesn't seem apparent that Asus can address this issue with a software/firmware update, as the ability to do so within the monitor's menu controls, or the ability to perform a firmware update via USB, seems to be absent. I might be mistaken about this and maybe Asus will be able to provide an effective solution in the future, but it is an issue I have seen been discussed on various forum platforms across the Web and also affecting other similar Asus monitor models besides this one. I also wish Asus would make ProArt displays with higher refresh rates - video content creators would be very excited about this too, especially those that double as gamers.

Great 4K Bright Display

The ASUS ProArt PA279CV monitor offers a stunning 4K display that connects many devices.This monitor is geared to those who want a crisp, colorful display for professional or just casual applications.The brightness and contrast make it ideal to view photos or videos. Although the brightness setting at 350 nits is not as high as more expensive monitors, it looks as though it has a higher light output.I connected this monitor to my Mac mini M1. I initially tried several connections (USB-C and HDMI) and found success with the HDMi that produced a terrific display.I do have some minor issues. This monitor has an on/off switch next to the power cable as well as an on/off switch on the front of the display. Is this needed?

The well-designed ports face downward, so connecting cables to them was tricky. My other complaint is that there are a series of button on the lower right of the display that are used to make control adjustments (brightness, contrast, color palette, etc.). My previous monitor used a joystick behind the monitor that was easier to use.If you're looking for a monitor with a great crisp display, do seriously consider this ASUS ProArt.

High quality screen with calibration but USBC issu

This is an outstanding monitor with calibrated screens including DICOM which is highly useful to me. I tested the 32 in version of this monitor with PerfectLUM and the factory calibration was right on target on the DICOM curve. Speakers are adequate, better than a similar 27 in 4k monitor I had from LG. Like having 4 inputs as I have multiple sources and 4 usb ports. So why 4 stars?USB-C connection has some issues. One is that in order to get usb 3.1 you have to run the monitor at 30 Hz over the USB-C connection. This is a limitation of DP 1.2 which this monitor uses. If you want to get 60 Hz and usb 3.1, you need to connect to the monitor with HDMI or DP and then use a USB to USB C connector. So instead of 1 cable, you have 2. HDR looks great on this monitor and ... MoreThis is an outstanding monitor with calibrated screens including DICOM which is highly useful to me.

HDR looks great on this monitor and functions perfectly.But that's not my major gripe. I had an Asus ProArt B550 mother board with Ryzen 5600x connected to this monitor over usb-c. The MB has Thunderbolt 4. Display looks great, but every time the CPU goes to sleep and the screen goes to sleep, if I turn the screen off, then when I turn it back on, the USB-C connection no longer works. To fix it, I have to go into the Factory Menu using the firmware update instructions on Asus web site, then do a factory reset. The regular reset does not work. I believe this issue has something to do with power delivery over usb-c, as if I have my HP laptop connected with usb-c and the HP goes to sleep then i turn the monitor off, when I resum and turn monitor back on again, USB-C is functioning fine.So now with the proart MB I am just connected with HDMI and no longer trying to use usb-c. Reserving USB-C for my laptop and ipad pro. It's not a big deal, but it's a weird flaw so I need to ding Asus for it. I have reached out to their support and asked them to replicate the problem. They have responded but waiting for them to call me.Btw, my monitor shipped with the V19 firmware already installed so anyone buying this now should not have trouble connecting an M1 laptop to the monitor.I considered buying a 14 in Asus Zephyrus gaming laptop but then I read some reviews that having usbc power and barrel plug both delivering power fried the laptop. Someone said Asus uses a faulty TI chip for their USBC. I can believe it given the issue I had with the Asus proart motherboard and this monitor.

It's pretty awesome, but a little small for 4k

The monitor looks great. Very happy with it, but side by side with the WQHD version it's very, very tough to see the resolution difference. 27 inches just doesn't necessitate 4k unless you are a serious creative. Even as a video editor and colorist, I'm not sure if this was the right choice.On the plus though, I haven't seen such a good monitor at this price point. It's not Flanders scientific levels of excellence, but the issues with quality control I read about before my purchase didn't bother me at all. I looked at Benq's professional monitors in person and was pretty disappointed.Things I don't read much about these monitors:There is some backlight bleed. It's very subtle, and completely unnoticeable unless you're looking at a mostly black screen.The ... MoreThe monitor looks great.

I anticipated getting a dual monitor stand, but I liked these enough to keep them.Not sure that I'd spend the extra on the 4k if I did it all over. It might be worth considering a larger screen if you're dead set on 4k. Between the dell, benQ, and proart though, this is a no brained imo.

Seeing is believing with the ProArt PA27CV

I'm very happy with the pair of ProArt PA27s I bought, they are a total godsend if you work in design or graphics and can't afford to step up to Eizos. Being of a certain age I need all the screen real estate I can get. Now that I can see what I'm doing I have finally begun to explore and extend the the uses and capabilities of my design software. Text is absolutely crisp, brightness (even at 50%) is astonishing. I haven't messed with the colour settings as they would appear to be good out of the box. It's another world.Whilst I can thoroughly recommend this particular model I can't extend that recommendation to the entire ProArt series. I initially bought one 27" and one 24" ProArt and found that the 24" was nowhere near as bright as the 27".

I initially bought one 27" and one 24" ProArt and found that the 24" was nowhere near as bright as the 27". Additionally the format and bezel dimensions of the 24" were much less appealing than the 27". The brightness issue with the 24" might just have been down to a faulty monitor but that was my experience anyway.These ProArt 27" monitors are monsters, so make sure you've got enough deskspace before you buy. And be prepared to mess around with the setup for a couple of weeks before you start to enjoy the benefits.

Solid

Using this monitor as part of my work from home set up in combination with a 2019 MacBook Pro connected by USB-C. I mainly use Figma in my day-to-day and have had a great experience using this monitor as my main screen.I've seen the feedback around a wobbly screen while pushing the buttons. It does wobble, but I've only pushed those buttons during the initial set up and haven't touched them since. The base is a good size so it doesn't wobble in any other situation.It's not a pretty looking monitor like the Apples, LGs, and Samsungs out there but it's solid. The build quality is sturdy. Working in UX design the picture and resolution is perfect for me. Having the USB-C connection is convenient.Consider where lighting is in your set up because there is glare ... MoreUsing this monitor as part of my work from home set up in combination with a 2019 MacBook Pro connected by USB-C.

Worth it if you need accuracy

I’ve done a ton of research on monitors over the last 2 months trying to find the right one. Please remember this is just my opinions.Situation: I am a graphic/web design student and manage a website professionally for a major organization, I do have some financial freedoms, this monitor is not cheap and not needed for students but a huge bonus to have.I originally was looking for an ultra-wide (45”+). However, if you need color/image accuracy, bigger is worse. There is no right size but 24-32” is a good range. I went with the 27” which is perfect for my design, I run a 2nd monitor for my other programs through my work computer, it’s not ideal for “non-technical designers”. If you want a big screen for multi-tasking and other stuff, don’t spend the money on ... MoreI’ve done a ton of research on monitors over the last 2 months trying to find the right one.

If you want a big screen for multi-tasking and other stuff, don’t spend the money on this. If you are looking for color/image accuracy, I think you found what you are looking for.System: I am running a 2020 M1 Mac Air w/ 16g ram, connection is through the usb-c port (touch on that later).Projects completed: I recently finished up some work and have completed about 3 illustrator projects and 5 photoshop projects since my purchase. I was working off my 13” screen and an HDMI connected 27” Acer. When I opened a few projects I had been working, I ended up changing all of my colors that weren’t part of the style guides, man was it off on the Acer.This Asus has everything a designer needs. RGB and CYMK are both very accurate, the cymk is not perfect but, you are looking at print colors on a screen. 4K is beautiful. I did hook up my Xbox series s and it looks good but doesn’t have frame rate needed so meh there but like I said, this is a monitor for designers. Movies play great through both HDMI, DP, and USB-C. I am still trying to get used to the board in this monitor charging my computer and other devices, It acts as a connection hub. Basically, this monitor hit every need.However…….If you plan on using usb-c connections (recommended), you will need to be a little tech savvy. These monitors do not work from the manufacturer with Apple. They just don’t. But. You can go to the asus website, download the firmware and drivers, install the drivers through commander, then move firmware to a thumb drive, plug it in to a usb 2.0, hit a sequence of monitor buttons which opens the hardware up for service. You run the file on the thumb drive through the monitor and then boom, it works. I typed this all out because it seemed daunting, but I was a first time to by following the directions step by step. Now, if you are looking at a monitor like this, you probably have the capacity to do what I just described, it’s worth it and will work fine with HDMI/DP until you do this. It seems like a big deal and I wish they did this at the factory but I know more about my monitor and how to troubleshoot it locally as opposed to shipping it back, waiting, and possibly being denied. It’s a pain in the butt but trust me, it’s totally worth the 15min it took.Overall, I’m very satisfied and would recommend this to designers/artists (digital). I would not recommend it to anyone outside of that field. If you are a student on a budget, you’ll get there eventually and be just fine.

Would be a nice monitor if it was fully functional and had better customer support

Bought this monitor after returning an LG with backlight bleed issues. I was pretty happy with it initially, aside from some uniformity issues it I liked the menu functionality, build quality, image, and that it's calibrated. I used it connected to my Mac via USB-C for a few days without issue, however when I switched from USB-C to HDMI, I was unable to get a signal to the monitor. I called customer support twice and they were quite unhelpful, looking for any excuse to blame my non-Asus hardware rather than actually help me figure out the problem in good faith that it was possible the monitor was at fault. Eventually I was able to narrow down the connectivity issue and figured out it wasn't the cables I was using and it wasn't the output devices I was using, but ... MoreBought this monitor after returning an LG with backlight bleed issues.

Eventually I was able to narrow down the connectivity issue and figured out it wasn't the cables I was using and it wasn't the output devices I was using, but rather that the Asus monitor itself was unable to receive a 4K signal through HDMI cables (including the one that came with the monitor). I was able to verify this by temporarily switching my computer's output to 1920 x 1080 before switching it back to 3840 x 2160, which for some reason tripped the monitor into recognizing the UHD signal, however it was lost again upon reboot. I figured all this out despite the lack of help from customer support even though I happened to be on the phone with them during this eureka moment, however the call got dropped right as I figured this out. Not sure where they are located, but every time I called them I had a pretty bad phone connection. Despite the fact that they are very thorough in taking down all your information every time you call them, I assume this is more for marketing purposes rather than call back purposes, as no one ever got back to me. Think I'll be returning this monitor and trying a dell instead...
