I'm loving this monitor, except for the dimmed brightness on the left and right hand side of the monitor is definitely noticeable. I might have to return it and get a monitor with a more even brightness distribution.
In addition to the more expensive OLED model, KTC also offers a cheaper 27-inch gaming monitor with an IPS panel. Although it doesn't have a KVM switch, dimming zones, or other bells and whistles, you do get a good and fast IPS panel at a low price. We tested the monitor. The price is even lower with the voucher code we received.
