Conclusion: The burning question is of course whether or not you really need a 4k monitor. And truthfully, the answer is no. Trust me, the PB287Q is a phenomenal piece of kit with an insane resolution, but running anything at 4k is going to require a fair amount of GPU power, so in addition to investing in this monitor you’re probably going to need to invest in an additional (and just as expensive) graphics card.
Summary: You've gathered by now that the PB287Q and monitors like it represent a new class of desktop display. If you're looking to upgrade or to build an all-new system, this monitor should definitely be on your radar. The core display technology, as we've seen, is surprisingly good for a TN panel, and Asus has wrapped a nice set of externals and extras around it. A year ago, I would have recommended a 27" IPS panel for a PC enthusiast considering this class of desktop monitor.
Excerpt: The growth and adoption of 4K resolution panels (most commonly 3840x2160) has really been the biggest story of the past year or so in the world of PC gaming. After a couple of TVs that ran at 3840x2160 over HDMI at 30 Hz found there way into our offices, the first real 60 Hz 4K monitor that I got some hands on time with was the ASUS PQ321Q .
Excerpt: Ultra HD monitors have become much cheaper in a very short space of time, and the £600 Asus PB287Q is sure to entice buyers with its price alone. The PB287Q comes hot on the heels of the AOC U2868PQU and the Dell P2815Q at £600, and both of these monitors had problems. The Dell P2815Q could only output Ultra HD resolutions at 30Hz, which meant there was an unbearable amount of input lag and choppy movement, even we performed the most basic the most basic of tasks.
Excerpt: Once upon a time a computer monitor was a separate thing to a television, with different requirements and different inputs. As the switch to flat panel displays alongside the increased media capabilities, and indeed popularity, of home consoles came to be, so the difference between a monitor and a television was blurred to the point that they overlap.
