Then, you can change the effect by scrolling through six options. You control the RGB with a dial on the bottom-center. You can remove the stand to use the 100mm VESA mount and still enjoy the lights. In back, is a swoopy version of the LG logo, along with a ring of RGB LEDs around the upright’s attachment point. The base features red trim on the bottom with LG and G-Sync logos in proud view. Finishes are the usual matte black in brushed and pebble styles. Styling is angular with corners rounded just enough to not be sharp. While not truly frameless, it’s closer to that goal than any other monitor we know of. The LG 27GN950-B has the thinnest bezel we’ve seen to date, just 5mm at the top and sides and 10mm on the bottom. Given the monitor’s bandwidth requirements, LG recommends using the supplied cables to run 4K resolution at 144 Hz. You’ll find a tiny clip in the box for cable management, along with wires for DisplayPort, HDMI and USB. Assembly and Accessories for LG 27GN950-BĪfter mating the base and upright with two captive bolts, the 27GN950-B’s panel snaps in place. It also carries G-Sync Compatibility certification from Nvidia with the same capabilities. That means it includes Low Framerate Compensation for speeds below 48 Hz. If you have the hardware, the 27GN950-Bcan deliver 144 Hz with HDR and FreeSync Premium Pro over DisplayPort. Definitely check your graphics card specs before pulling the trigger on this monitor. To run at full honk, you’ll need a graphics card (likely one of the best graphics cards) with DisplayPort 1.4 capability because LG uses Display Stream Compression to get all those pixels over a single cable. 144 Hz 4K monitors are rare and have serious bandwidth requirements. The big story here is the 27GN950-B’s refresh rate. By selectively dimming the individual LEDs, it achieves HDR quality that comes close to its FALD cousins. Rather than the full-array local-dimming (FALD) units used by Asus and Acer, LG employs an edge-lit backlight but offers a local dimming feature of its own. The principal reason for this is its backlight.

That undercuts the aforementioned Asus and Acer monitors significantly. At this writing, LG is selling it for $800. The 27GN950-B’s price of entry is the first thing we noticed. LG 27GN950-B (Black) at Walmart for $790 (opens in new tab).
