Gaming monitors are great, but most of them sacrifice visual quality for high refresh rates, and the best options usually carry a high price tag. Acer's 27-inch CB271HU display might be locked at 60Hz, but it uses a high-quality IPS (in-plane switching) panel and now only costs $220 from B&H Photo. That's a savings of $80 off the original MSRP.
This monitor has a 1440p (2560x1440) IPS display with a 60Hz refresh rate, support for up to 1.07 billion colors, a response time of 4ms, and a peak brightness of 350 cd/m². It also has a matte finish, so there should be minimal or no glare, even if your PC is sitting next to a window or other light source.
Other features include a 60 degrees of swivel movement, compatibility with VESA mounts, built-in speakers, and inputs for DVI, HDMI, and DisplayPort. It can also rotate to stand vertically.
While you can easily find 120Hz monitors in this same price range (even some with the same 1440p resolution), they either have lower-quality Twisted Nematic panels or are physically smaller. This large 27-inch IPS display is a great option if you want more accurate colors, or if you're looking for a second (or third) monitor for your existing setup.
