We've already reviewed the first shipping 4K laptop, a 15-inch Toshiba Satellite model, as well as Apple's 4K-friendly Mac Pro desktop, but plenty of current PCs (with Nvidia's newest generation of 8000-series GPUs, for example) can push games to higher-than-1080p resolutions.
But to appreciate that, you'll need a 4K monitor, which are, like their TV counterparts, still new and expensive. Monoprice, known for its very reasonably priced PC and audiovisual accessories, has just announced a new model for less than some comparable versions we've seen.
Monoprice's new 28-inch ultra-high definition monitor, running at 3,840x2,160 pixels, will be available to pre-order in July and generally available sometime in the third quarter of 2014. The exact price hasn't been set yet, but we expect it to run between $550 and $600. Earlier this year, similar monitors were more than $1,000, but some recent price cuts from Dell and Samsung have started to drive prices down.
In-person, the Monoprice display is reasonably thin, with a brushed-metal bottom bezel and a sharper look than more plastic-feeling budget displays. It includes three HDMI ports, for connecting multiple devices, plus a DisplayPort. We used a 4K-ready gaming desktop from boutique PC maker Origin PC to play Battlefield 4 at full 4K resolution and "ultra" graphics settings, and it looked and played fantastic.
Mainstream PC gamers aren't going to transition to 4K anytime soon, but with hardware prices coming down, it's one area where PC games can offer a real point of differentiation from their higher-profile console counterparts.
