I hooked up the ASUS PB287Q 4K display on 3 systems powered by AMD and NVidia graphics solutions. There was no issue with the plug-and-play support and I was able to get the 3840x2160 resolution running on all systems, with ease. I tested the screen with the NVidia 340.3 BETA driver, and AMD's Catalyst 14.7 Beta Driver.
The HDMI inputs support the 3840x2160 resolution with a refresh rate of 30 Hz. For the full 60Hz, I had to use the DisplayPort Input, go into the OSD, check under the System Tab Setup, where the monitor defaulted the DisplayPort Stream to DP 1.1 (which means UHD resolution at 30Hz on an SST monitor).
Whilst I have limited prior experience with testing monitors, I took my i1Display Pro colorimeter, and used it alongside SpectraCal's CalMan 5.201 software package.
Since this is my very first monitor review (which means I might screw things up around here), I decided to also take a look at some of the features PB287Q comes with, such as the ASUS GamePlus. This adds a crosshair in the screen-center, or displays a countdown timer for use whilst playing realtime strategy games.
Of course, both options cannot be enabled simultaneously, but that shouldn't be a problem (right?). There are four available crosshair designs to choose from, and the timer can be placed on the bottom, middle or top of the screen, and set for a limited duration of 30, 40, 50, 60, or 90 minutes.
This is an interesting feature, which overlays real document sizes (A4, B5, letter), photo dimensions ("x10", 5"x7", 4"x6", 3"x5", 2"x2") and grid-lines on the screen.
This is usually a more professional feature you would encounter in more high-end screens, where image size editing is somewhat important. Whilst it isn't something to get crazy about, it's a handy feature to have if you're a designer.
PIB & PbP
PB287Q can allow you to view content from two sources simultaneously, with the Picture-in-Picture or Picture-by-Picture modes. PiP adds the secondary input in one corner of the display, whilst PbP splits the screen the screen down the middle.
