The Asus PB287Q (MSRP $649) is a 28-inch monitor with a native resolution of 3,840 x 2,160, a 1ms G2G response time, a 60 Hz refresh rate, and 10-bit color depth. That's a lot of gold stars for the price.

So, should you rush out and buy it straight away? Maybe—if you're a gamer. The PB287Q is naturally poised to provide a fast, fluid, lag-free gaming experience—and no competition is going to beat that 1ms response time. But for everyone else, we have to advise that you wait a few months until the rest of the competition's on the field.

Unimpressive, but very reliable

You might be wondering how Asus gets away with selling the PB287Q for just $650 when last year's 4K monitors generally cost multiple thousands of dollars. It's because this monitor uses a TN (Twisted Nematic) panel, arguably the cheapest type, and last year's crop were mostly IPS IGZO varieties.

The PB287Q doesn't support the color space required by graphic artists and designers.

Your next question is probably, "Oh snap, does it look awful?" Thankfully, no. While the PB287Q lacks in the viewing angle department, it looks just fine when viewed head-on: Colors are vivid and clear, with little to no visible banding.

What's more, the screen's anti-glare coating is fairly mild, which preserves the crispness of all that 4K goodness while combating ambient glare. Disappointingly, the PB287Q doesn't support the wider color space required by graphic artists and designers, but at least it does a solid job with traditional sRGB mapping, thanks to its 10-bit color depth.

A 1ms response time makes the PB287Q a godsend for gaming enthusiasts.

Ultimately, this is some of the better color accuracy I've seen from a TN panel, but it still isn't perfect (check out the Science Page for a closer look).

There is one definite advantage to the TN panel type, however: response time. A 1ms response time and 60Hz refresh rate make the PB287Q a potential godsend for gaming enthusiasts. I took a spin through Skyrim with 4K textures and meshes, and it was a beautiful thing.

The panel's core performance is probably not the strongest we'll see this year, but considering price and pedigree, it's definitely good enough if you've been itching to hop aboard the 4K train. Just don't expect the intense color purity associated with IPS panels or the deep black levels associated with VA panels.

More function than form

The PB287Q doesn't really need to look good: It's an affordable 4K monitor with a decent picture, so it could easily skate by on merit alone. To that end, there's nothing really "sexy" about this display—in fact, it exudes an air of asceticism.

Smooth, matte-black plastic, 19mm bezels, and a thin panel depth give the PB287Q a modern appearance. The neck and base lend plenty of flexibility to the panel, too: Users can adjust height, pivot side-to-side, and rotate to portrait orientation. If you'd prefer to wall-mount the PB287Q, go right ahead.

Glowing indicators along the front of the bezel guide your fingers to tactile buttons on the rear. Pressing any button (besides Power) prompts a contextual on-screen display menu, allowing you to select things like the input source, screen luminance, or picture mode. I've read some complaints about this control scheme, but in my opinion it's no more difficult to use than any other.

In a recessed area on the back of the display, you'll find a somewhat limited selection of input options that includes two HDMI 1.4 (MHL-compatible), DisplayPort 1.2, and PC audio in for external speakers. If you don't want to use external speakers, the PB287Q also has a headphone jack and two built-in 2W speakers.

Tricks old and new

As far as extra features and software options go, the PB287Q has no shortage of them. Just like last year's PQ321Q, this monitor's best features—Picture-in-Picture (PiP) and Picture-by-Picture (PbP) modes—help you get the most out of its 4K resolution.

Both of these modes allow you to view two sources simultaneously, with PiP placing a smaller window in the top or bottom right corner of the screen. PbP has a letterbox appearance with black bars at the top and bottom of the display, allowing for two equally-sized windows to display two different sources side-by-side. This ability to display simultaneous sources is one thing that definitely sets the 4K-capable PB287Q apart from non-4K displays.

Browsing the on-screen display confirms that a number of Asus' standby features are making yet another return. For example, the company's "Splendid" modes are in full force. These are easy-to-use pre-sets that optimize the display for various kinds of content and environments. There are eight modes in total: Scenery, Standard, Theater, Game, Night View, sRGB, Reading, and Darkroom.

There are plenty of picture and calibration options in the menu, as well as the usual Asus tricks: ASCR, which gently boosts contrast ratio; EyeCare, which reduces blue light emission; and QuickFit, which fits the screen to various document, grid, and photo pre-sets for editing and mapping. They're all welcome additions, but let's be honest—no one wants this monitor for extra features.

A gamer's companion

The Asus PB287Q (MSRP $649) has many strengths: decent color production, lightning-fast response time, a smart build, and a (comparably) dirt-cheap price. Despite all that, it's not suited for every buyer. Professionals who need a wider color space, for example, are out of luck. And those of you waiting for the best picture quality at the lowest price—give the industry a few months before you throw the switch.

If you're an avid gamer, however, the PB287Q may not see any competition this year. It's already essentially optimized to provide a stellar gaming experience, and the panel's 10-bit color depth eliminates a lot of the color mixing problems commonly associated with TN panels. Just remember that you'll need a fairly powerful graphics card (and the right cables) to max out the full 4K resolution at 60 Hz.
The Asus PB287Q (MSRP $649) is one of the most affordable 4K monitors on the market. One reason it's so much cheaper than last year's 4K monitors is because it uses a TN (Twisted Nematic) LCD panel, which has pros and cons. For instance, this panel covers the sRGB color space only, meaning it won't fulfill the needs of professionals who require a wider color space such as Adobe RGB. I measured decent contrast and fairly accurate color here, but overall this panel is average.
The PB287Q adheres to the sRGB digital color space, which means its red, green, and blue primary colors are set to roughly the same saturation/hue as the Rec. 709 HDTV color standard. One thing that sets this display apart from the crowd, however, is its 10-bit panel, which provides more information for each color displayed. The result is average, reliable color performance, with very little of the ugly banding/striping that sometimes plagues 8-bit panels.

Testing revealed that this panel produces a green primary of the proper hue, though it's slightly oversaturated; a properly saturated blue primary, though it is slightly skewed in hue; and a notably undersaturated red primary. The white point lined up nicely with the sRGB ideal, however, and secondary color points were quite accurate as well. An IPS panel would have stronger performance, but but would also be priced as such.
Error within shades of the grayscale—a display's blacks, grays, and whites—is measured as a collective number called DeltaE. This number measures discrepancies within each grayscale step, traditionally reported as steps of "IRE," a holdover from the days of analog displays.

I measured a DeltaE of 4.74 across the grayscale, with most of the error reported in the 30, 40, and 50 IRE. This means that middle-luminance grays and whites are less "neutral" (free of visible color) than is ideal. This isn't heavily visible, fortunately, but it's also not a great result.

Our RGB balance test measures the relative emphasis given to a display's red, green, and blue sub-pixels throughout the panel. Each pixel is made up of three sub-pixels, which work as color filters to create the monitor's primary colors: red, green, and blue. Ideally, a panel emphasizes sub-pixels evenly as light from the backlight passes through.

In this case, testing revealed that the PB287Q tends to lightly favor the blue sub-pixel over the red and green, giving its grayscale a "cooler" appearance (read: blue-ish) than is ideal for the sRGB picture mode.

A digital display's gamma correction curve is what determines how much luminance it adds at each step of the grayscale. Typically, computer monitors adhere to a gamma curve of about 2.2, as they're often used in well-lit environments like an office or warehouse. When a digital display has a "smaller" gamma sum (such as 2.0 or 1.8), it adds more luminance out of black than if it had a "larger" gamma sum (2.3, 2.4).

In sRGB mode, the PB287Q tested with a smaller gamma sum of 2.14, which means is gets bright out of black tones very quickly. This sum indicates that the PB287Q is better suited to a brighter environment with more ambient light, though you could always use the Gamma control in the menu to adjust to a darker environment.
