LG UltraGear GN5 / GN6 / GN7

The LG 27GN650-B is a good monitor overall. It's great for gaming because it has low input lag, a high refresh rate, fast response times, and VRR support, resulting in a smooth and responsive gaming experience. It's good for work and media consumption, but its 1080p resolution might be too low for some. It's okay for gaming in HDR, although it's mainly due to its great gaming performance, as it doesn't get bright enough for a true HDR experience, has a low contrast ratio, and lacks local dimming.

The LG 32GN650-B is good for mixed usage. It's intended to be a gaming monitor, with a high refresh rate, fast response time, and low input lag, but it also performs well in other areas. Despite its disappointing ergonomics, its large screen size and 1440p resolution are great for productivity, watching media, and content creation. That said, it's not ideal for co-op gaming or sharing content with co-workers or friends since the poor viewing angles result in a washed-out image when viewed from the side. The HDR experience is also lacking as it doesn't have a wide color gamut and can't get bright enough to bring out highlights.

The LG 32GN600 is a decent monitor for most uses. It has low input lag and a fast response time, making it a great choice for gamers. The large, relatively high-resolution screen is decent for office use or media creators, but it has terrible ergonomics and poor viewing angles. It has great contrast and decent black uniformity, so it's a decent choice for HDR gaming or watching videos in a dark room.

The LG 27GN750-B is a good monitor for most uses, and it performs best as a gaming monitor. Gamers should appreciate the high refresh rate, outstanding motion handling, extremely low input lag, and FreeSync VRR support. It has wide viewing angles, which makes sharing your screen with coworkers or friends easier, and it performs well in bright environments because of its very good reflection handling. Unfortunately, HDR content on this monitor isn't much different than SDR content since it can't display a wide color gamut or get bright enough to bring out highlights.
