Just monitor stuff
I have lots more to say about the PB287Q's super-dense panel, but we should pause to take a look at some of this monitor's other features first. That's especially important because this product shares the same panel type with some competition, including the Samsung U28D590D.
Asus believes it has one-upped Samsung by setting a $50-lower list price and providing a more upscale physical configuration. I'm inclined to agree. The Samsung monitor offers only a tilt adjustment, while the PB287Q can swivel, tilt, change height, and....
Yes, it pivots into portrait mode, making a triple-4K portrait config a live option. The stand feels sturdy and well balanced, too. If you'd rather put the monitor on a wall mount or the like, the included base attaches via a standard 100-mm VESA mount, so the Q should be compatible with a broad range of mounting hardware.
There are several inputs on the back of the monitor. Oddly, access to them is partially blocked by a long, plastic shroud visible in the picture above the, er, one above. With the shroud popped off, the ports are easier to access. Those ports include a single DisplayPort input, two HDMI sockets, and an analog audio jack.
99.9% of the time, you'll want to use the DisplayPort input, which is the only way to get 4K at 60Hz. The HDMI inputs can drive the whole display at lower resolutions or refresh rates, but they're probably most useful as aux inputs for the monitor's picture-in-picture capability. The first HDMI port also supports MHL 2.0, so it can receive a 1080p video signal from a phone or tablet and supply power to that device over the same connection. Kinda nifty, in theory, although I haven't tried it yet.
Menus and such
Generally speaking, I'm not a fan of the menu systems in most monitors. They're not exactly paragons of UI design, and too often, they seem to be missing obvious features. Asus, however, has done a reasonably good job with the PB287Q's on-screen display and menu options. Nothing really obvious is missing. If anything, the firm went overboard with the choices in a few places, such as the "Splendid" color profile menu, which includes modes dubbed scenery, standard, theater, landscape, game, night view, sRGB, reading, and darkroom.
Ain't nobody got time for that.
The sRGB option does produce colors that appear to be closer to our post-calibration settings than the default "standard" mode, for what it's worth.
Most OSD menu systems make me feel kind of clumsy. I always hit "back" when I want "select" or vice versa. That problem is made worse in the PB287Q by the placement of the array of seven navigation buttons on the back side of the enclosure. Associating them with the white dots on the front of the monitor, which must then be associated with on-screen action icons, is almost beyond me. I'm never sure my finger's in the right place. It's like being 17 all over again.
