Review on LG Electronics 27GN750 B Compatibility Adjustable 1920X1080P, 240Hz, Blue Light Filter by Steve Morikawa

Although marketed as a PC gaming monitor, it's also great for console/retro/arcade gaming. I tested it with OSSC and it syncs with almost any mode you can use. There are also aspect ratio options and you can choose to "just scan" to avoid unwanted scaling of your perfect pixelated output from OSSC. The latency is also very low. It can also receive 4K signals and downscale them to a native 1080P panel resolution. I think the only downside is that there is no blur reduction mode, presumably to avoid red pixel blurring due to the inherent fast response time of IPS technology.
