An anonymous reader writes "After the HD revolution, display manufacturers rolled out gimmick after gimmick to try to recapture that burst of purchasing (3-D, curved displays, 'Smart' features, form factor tweaks, etc). Now, we're finally seeing an improvement that might actually be useful: 4K displays are starting to drop into a reasonable price range. Tech Report reviews a 28" model from Asus that runs $650. They say, 'Unlike almost every other 4K display on the market, the PB287Q is capable of treating that grid as a single, coherent surface. ... Running games at 4K requires tons of GPU horsepower, yet dual-tile displays don't support simple scaling. As a result, you can't drop back to obvious subset resolutions like 2560x1440 or 1920x1080 in order to keep frame rendering times low. ... And single-tile 4K at 30Hz stinks worse, especially for gaming. The PB287Q solves almost all of those problems.' They add that the monitor's firmware is not great, and while most options you want are available, they often require digging through menus to set up. The review ends up recommending the monitor, but notes that, more importantly, its capabilities signify 'the promise of better things coming soon.'"
