ASUS PQ321Q UltraHD Monitor Review: Living with a 31.5-inch 4K Desktop Display

Coming into this review, I wasn’t totally sure what to expect from the ASUS PQ321Q, or any monitor with this high of a resolution. I love the screen on my iPhone 5 and my retina iPad, but I hold those really close to my face. Since I sit a couple feet away from a monitor, was I really going to notice the difference? Yes, yes I did.

Even coming into the office right after a standard 30”, 2560x1600 display, the difference is huge. You get either a larger desktop, or a far crisper screen, or possibly both. It isn’t a small difference, but one that I can notice easily, and every single time I sit down to my desk. It also is apparent that many application vendors have to hurry up with their software support for DPI scaling, because when it isn’t supported correctly it is really ugly out there.

The ASUS PQ321Q does have its share of problems. The color gamut isn’t perfect and leads to a good number of errors in the red, orange, and yellows of the spectrum. I found yellows to be the only one that I could easily notice when I looked at photos, but I did see red and orange issues as well. The dual HDMI 1.4a inputs are nice, but with HDMI 2.0 possibly coming later this year you are going to be limited to 30p on those inputs. The OSD could also be improved upon, as it works, but lacks any location or size adjustments and takes up almost half the screen when active.

In the end, my feelings about the ASUS PQ321Q wind up being very simple. Of the dozens of displays that I’ve reviewed for AnandTech so far, this is the one I want to hold onto the most. The razor sharp screen is just addictive to use, and you realize this is the future for displays. I’m sure over the next few years that performance will improve, prices will come down, and features will increase, and that helps everyone. But I want this now, and I don’t want it to leave my house.

The ASUS PQ321Q is pricey, and I can’t say that getting three or four 30” 2560x1600 panels isn’t a better deal, but it’s not the same as having one display that looks like this. In the end, I give the ASUS PQ321Q a Silver Award, which is the highest award I've personally given to any display. It's not perfect, but there isn't a display that's come across my desk that left me in constant awe over how incredible it was to use on a day-to-day basis that the ASUS has. It's also effectively killed any thoughts I've had about buying a laptop like a MacBook Air instead of a Retina MacBook Pro, because I can't imagine going back to a regular display. The next few years of high resolution displays can't come fast enough now.
