LG is leading the charge with big, cheap gaming displays, having recently unveiled a 32-inch 4K model for less than $500. If you're willing to settle for QHD resolution, you can do even better with another new 32-inch model, the 32QK500-W. It packs AMD's FreeSync with a 75 Hz refresh rate and 8 ms response time, making it a decent gaming monitor. On top of that, the 8-bit + FRC IPS panel offers excellent viewing angles and up to 1.07 billion colors, so it'll be good for streaming video, too. All of that should come at a price around $300, making it one of the cheaper 32-inch displays out there.
