Ultra HD is Not So Ultra
In order to get 3840x2160 working at 60Hz, you'll need to enable multistream transport mode within the on-screen display on the ASUS PQ321QE. Out of the box, you'll only see 30Hz at the mammoth resolution, which really hurts when you first see it.
I plugged the monitor into a GIGABYTE BRIX PC toward the end of my testing, which worked surprisingly well. It splits the monitor into two 1920x2160 screens, which are joined together in the middle for the 3840x2160 resolution.
4K is still a wobbly road, which is why we're not seeing it adopted as quickly as I would like. Connectivity needs to be worked on so that it returns to a plug and play world for monitors.
The quality: It really makes you sit there and say "wow." The sheer amount of pixels on the 31.5-inch screen is just astonishing. Comparing my 39-inch 4K TV to this 31.5-inch 4K monitor is quite the showdown. The TV looks great from a distance, but it's not great for on-your-desk work.
The 31.5-inch ASUS PQ321QE, on the other hand, is perfect for your desk. I'm sitting a little more than an arm's length away from the PQ321QE as I write this review, and it feels perfect. It's absolutely gigantic in front of me, not only in physical size, but pixel density, too.
4K is the future: It really is. Once the connectivity issues are worked out, it'll be great. When the day arrives that you can shoot 4K video from your smartphone (with some smartphones already sporting 4K-capable rear-facing cameras), playing this back on your 4K monitor will be sublime.
The price: ASUS has priced the PQ321QE out of the range of probably 95 percent of people. Sure, I've paid over $3000 for a monitor before, but with much cheaper 4K monitors on the horizon, the $2800 price is a hard high-resolution pill to swallow.
Some issues on certain PCs: Not all PCs are 4K-capable.
After testing out the Seiki Digital 39-inch TV, I've been itching to get the ASUS PQ321QE on my desk. Now that it's here, I don't want it to go away. I've loved nearly every single minute with it, and it really does help with productivity to have that many pixels sitting in front of you.
I was able to have countless windows open while watching a full 1920x1080 movie without having to overlap anything.
Games look absolutely sublime at 4K, almost to the point where they look unbelievably high-res--which, of course, they are. Running 3840x2160 and seeing that resolution being played in front of you is something that truly needs to be seen in order to be believed.
The only problem I have here is the price. I feel ASUS has priced themselves out of the market with the PQ321QE, at least for the normal consumer. For professionals, it is a great investment, as I don't see them needing another monitor until this one died, or it was superseded in the future with new technology or--gasp!--a higher resolution screen.
No matter what, you will certainly not be disappointed with what ASUS has on offer here with the PQ321QE display.
