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.

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.

Stand
Width

18.7" (47.5 cm)

The stand is nearly identical to the other UltraGear monitors. It supports the monitor well, but doesn't completely stop it from wobbling.

The stand has the same ergonomics as the higher-end 27GL850-B. It can rotate to a portrait orientation, but only on one side.

There is a quick release on the back, but only basic cable management.

7.0 Build Quality

The 27GL650F-B has decent overall build quality, nearly identical to the other UltraGear monitors we've tested. It's mostly plastic, but there are no obvious issues.

7.4

Picture Quality

The LG 27GL650F-B delivers decent overall picture quality. Like most IPS monitors, it has a mediocre contrast ratio, so blacks look gray in a dark room, but it has good viewing angles, great for co-op gaming. It has great peak brightness and decent reflection handling, so it can easily overcome glare in a bright room. It has excellent gray uniformity, but unfortunately, it has poor black uniformity, with noticeable backlight bleed and clouding. Although this monitor supports HDR, there is little benefit to it, as it can't get very bright in HDR, and can't display a wide color gamut.

6.3 Contrast
Native Contrast

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.

Out of the box, the LG 27GL650F-B has great accuracy. Most people won't notice any inaccuracies in colors or shades of gray. Gamma doesn't follow the sRGB target curve though, so some scenes to appear too bright, and some to appear far too dark.

7.0 Reflections

The LG 27GL650F-B has decent reflection handling, similar to the LG 27GL850 and the 32GK650F. There shouldn't be any issues in most rooms, but if there are bright lights or windows opposite the display, there may be significant glare.

9.1

Motion

The LG 27GL650F-B has excellent motion handling. It has an excellent response time, although there is some noticeable overshoot, and the backlight is flicker-free. There's an optional black frame insertion feature, which can improve the appearance of motion. This monitor supports FreeSync and is also NVIDIA G-SYNC Compatible certified, so the variable refresh rate feature works automatically when connected to a recent NVIDIA graphics card.

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.

Inputs

The LG 27GL650F-B has outstanding low input lag, delivering a very responsive gaming experience. Unfortunately, the low 1080p resolution might not be ideal for some people, as there is less detail in games, and text isn't as sharp as screens with a higher pixel density.

Features

The LG 27GL650F-B is a basic monitor, with very few additional features. It doesn't have built-in speakers, but it supports HDR10. There are very few additional gaming features, but like other LG UltraGear monitors, it can add virtual crosshairs to any game. The controls are very easy to use, and the on-screen display is well-organized and intuitive. It comes with everything you'll need to get started, but there's no DisplayPort cable, which is a bit disappointing.
