Asus PB287Q 28-Inch 4K Monitor Review: Ultra HD For $650

Asus PB287Q 28-Inch 4K Monitor Review

We kicked off our 4K display coverage at the start of this year with Asus PQ321Q 4K Monitor Review: Top-Shelf Ultra HD For $3500. That was followed by Dell UltraSharp 32 Ultra HD Monitor Review: UP3214Q At $3500. See the pattern so far? At least in the first half of 2014, 4K was a very, very pricey proposition. And it gets worse if you're a gamer trying to push more than 8 million pixels at 60 frames per second. That's a lot of potent graphics hardware.

To be fair, both of the displays we reviewed offered stunning image quality. But they were also saddled with a handful of usability issues that you'd expect from a first-gen, cutting-edge product. In fact, it took AMD and Nvidia some time to optimize their drivers for a more pleasant user experience with Radeon and GeForce cards hooked up to tiled 4K screens. Of course, paying thousands of dollars didn't help make the idiosyncrasies any easier to swallow.

Those displays cost quite a bit less today, though they'll still run you $2500 or so. Fortunately, as the second generation of Ultra HD monitors slowly materializes, we expect significantly lower prices. Earlier this year we heard about a 28-inch panel that Samsung, Dell, and Asus were planning to sell at a surprisingly low price point under $700. We're already on the sample list for Samsung's UD590 and Dell's P2815Q. But Asus surprised us with a brand-new PB287Q, just in time for a pre-Computex review.

A couple of specifications leap out to tell you how Asus got its price so low. Principally, the PB287Q uses TN technology, rather than one of the many flavors of IPS. If you recall our reviews of the 32-inch Ultra HD screens, they are based on an exotic IGZO panel manufactured by Sharp.

The core part here is made by Chi Mei Optoelectronics and sports a pixel density of 157 ppi. Even though its fundamental technology is something of a throwback, there is no skimping on the remaining features. Almost all TN panels achieve 8-bit color depth by using 6-bits plus FRC. This brand-new part achieves 10-bit color by using 8-bits with FRC like many professional monitors we've reviewed. So even though most users will use an all-8-bit signal chain, it will accept 10-bit formats too. And all incoming 8-bit content is upconverted by the PB287Q. The end result is a palette of 1.07 billion colors.

Will that make images more colorful? Not exactly. What the extra bit depth will do is smooth the gradients in subtle color transitions. The best examples are things like blue sky, clouds, or fire. Where an 8-bit panel might show subtle banding or macro-blocking, a 10-bit capable display can reduce or eliminate those artifacts even though it's using FRC to work its magic.

Another feature not mentioned in the spec table is the non-PWM backlight. We have a couple of upcoming reviews of BenQ displays that discuss this in more detail. Essentially, though, pulse-width modulation can result in flicker and eye fatigue for some users. By applying constant current to the backlight and varying brightness at the pixel level, overall intensity can be reduced without introducing flicker. Asus calls its version of the technology EyeCare.

Since the PB287Q is an sRGB display, it’s not specifically aimed at professionals. In fact, the feature set and low price make this more of an enthusiast-oriented monitor. Asus includes some tantalizing features like VividPixel, QuickFit, and GamePlus. Along with the fast response and low input lag endemic to TN panels, it ends up looking best-suited to gamers. Let's take a closer look.

    - We need to see Article comparing IGZO - PLS - AHVA panels at first place.

    - What happened with AHVA panels M270QAN01.0 , M270QAN01.1 , M320QAN01.0 ,M320QAN01.1 from AUO that were planed for 2014 production ? We are in September 2014 now and no one offers them.

    It would be good to know who uses which panel, we have ASUS, Iiyama, AOC, DELL, Viewsonic, Samsung selling 4K displays all based on TN...

    I would like to see compare to AOC U2868PQU 4K display.

    There is not so many "cheap" 4K monitors on market and I would like to choose best for myself...

    What I know, there is two other products too:
    Philips Brilliance 288P
    Samsung U28D590D
