The LG 27GL650F-B is a very good 1080p, 144Hz IPS monitor with great gaming performance. It has outstanding motion handling, with an excellent response time, flicker-free backlight, and a fast refresh rate. It delivers decent overall picture quality, with wide viewing angles, excellent gray uniformity, and great accuracy out of the box. Unfortunately, like most IPS monitors it doesn't look as good in a dark room, as it has a low contrast ratio and bad black uniformity. This monitor supports HDR, but this doesn't add much unfortunately, as it can't get very bright in HDR and can't display a wide color gamut.

Our Verdict

7.8 Mixed Usage

The LG 27GL650F-B is a good monitor for most uses. It's a great gaming monitor, with excellent motion handling and low input lag. It's a good office monitor as well, with great viewing angles, decent reflection handling, and passable ergonomics. Unfortunately, the low native resolution isn't ideal for multitasking, and it doesn't look as good in a dark room.

See our Mixed Usage recommendations
7.7 Office

Good monitor for office use. It has wide viewing angles, acceptable ergonomics, great peak brightness, and decent reflection handling. The low native resolution might bother some people though, and it doesn't have a built-in USB hub.

8.2 Gaming

The LG 27GL650F is a great monitor for gaming. It has an excellent response time, outstanding low input lag, and an excellent refresh rate. Unfortunately, the low native resolution isn't ideal for some games, and it doesn't look as good in a dark room, as it has a low contrast ratio and poor black uniformity.

See our Gaming recommendations
7.7 Multimedia

This is a good monitor for multimedia. It has excellent low input lag, wide viewing angles, and excellent gray uniformity. Unfortunately, it isn't great for watching movies in a dark room though, and the low resolution isn't ideal for some uses.

See our Multimedia recommendations
7.7 Media Creation

This is a good monitor for media creation. It has great viewing angles, a fast response time, acceptable ergonomics, and excellent low input lag. It has an excellent SDR color gamut, but the Adobe RGB coverage might be too low for professional photo editing.

See our Media Creation recommendations
6.9 HDR Gaming

This is a decent monitor for HDR gaming, mainly due to its great gaming performance. It has outstanding low input lag and an excellent response time, and it supports FreeSync, for a nearly tear-free gaming experience. Unfortunately, HDR doesn't add much, as it can't display a wide color gamut, and can't get very bright in HDR.

The LG 27GL650F-B has a decent design, very similar to the other LG UltraGear monitors we've tested. It has a basic design, with no RGB bias lighting, limited cable management, and limited ergonomic adjustments, but it has decent build quality, with no obvious flaws or issues.

Like all IPS monitors, the LG 27GL650F-B has a mediocre contrast ratio. This results in grayish blacks, which is especially noticeable in dark scenes in a dark room. The 27GL60F-B we tested has better contrast than the 27GL850-B, but this varies between individual units.

The LG 27GL650F-B has an excellent response time, but it is significantly slower than the 27GL850-B on some transitions. This results in a bit more noticeable blur behind fast-moving objects.

Normally, we would recommend the 'Fast' overdrive setting, as there is some noticeable overshoot/undershoot with the 'Faster' setting. In this case though, the difference in response times between the two settings is so significant that we recommend the 'Faster' setting, despite the downsides to this mode.

Like the rest of LG's UltraGear lineup, the backlight is completely flicker-free, which is great. Unlike the 27GL850-B though, there's an optional black frame insertion feature. This feature is only available at 120 or 144Hz, and it causes a noticeable reduction in peak brightness, but there is slightly less blur behind fast-moving objects. This feature can be activated by enabling the 1ms Motion Blur Reduction setting from the 'Gaming' tab on the monitor's on-screen display. Note that this feature isn't available if FreeSync is enabled.

The LG 27GL650F-B has an excellent refresh rate, and it supports AMD's FreeSync variable refresh rate technology. It's also certified by NVIDIA as G-SYNC compatible, so it'll work with NVIDIA's adaptive sync drivers, as long as you have a recent NVIDIA graphics card. This monitor received certification while we were testing it, so you might have to update your drivers for it to work. Certification for this monitor was added with NVIDIA Game Ready Driver version 436.30.
