Acer's XB280HK 28-inch 4K NVIDIA G-Sync monitor is just $599 right now

One of our favorite 4K monitors is on sale right now, with the Acer XB280HK available at Newegg for $599, down from its normal price of $899. The Acer XB280HK is a 28-inch 4K monitor that has NVIDIA's G-Sync technology built-in, with our review available right here.

Sure, it's a TN-based panel and not IPS, but for $599 you're getting a silky-smooth 4K monitor if you have the VGA chops to get there. 4K 60FPS isn't too hard these days with a mix of Medium/High details in most games, with Grand Theft Auto V able to hit 4K 60FPS on something like a GeForce GTX 970 without a problem.

You'll need the following promo code "EMCARKW22", which is available until April 22, so get in quick.
