The LG UltraGear 27GL650F-B is a good 1080p, 144Hz IPS monitor with great gaming performance. It has an excellent response time resulting in clear motion, a black frame insertion feature to reduce motion blur, a low input lag, 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 poor black uniformity. This monitor supports HDR, but this doesn't add much, as it can't get very bright in HDR and can't display a wide color gamut.

Our Verdict

7.2 Mixed Usage

The LG 27GL650F-B is good for most uses. It's a great gaming monitor thanks to its excellent response time, incredibly low input lag, and high refresh rate. Its large screen size is good for productivity, but the 1080p resolution might be too low for some to watch videos. Unfortunately, although it supports HDR, it can't display a wide color gamut.

Compared To Other Monitors

The LG 27GL650F-B is a great budget gaming monitor. See also our reviews for the best gaming monitors, the best monitors under $200, and the best gaming monitor sizes.

Gigabyte M27Q

The Gigabyte M27Q performs better than the LG 27GL650F-B for most uses. The Gigabyte has a higher resolution to produce a sharper image, and it also delivers a smoother gaming experience due to its higher refresh rate and faster response time. It also has more features, like USB-C input, a Picture-in-Picture mode, and a built-in KVM switch.

LG 32GN600-B

The LG 27GL650F-B and the LG 32GN600-B use different panel technologies, each with strengths and weaknesses. The 32GN600-B has a VA panel, with much better contrast and better black uniformity, so it's a better choice for a dark room. The 27GL650F-B has an IPS panel, with better viewing angles, and it also has much better ergonomics and a smaller, lower-resolution screen.

LG 27GN650-B

The LG 27GN650-B is the newer version of the LG 27GL650F-B with identical features. The differences are that the 27GN650-B has response times and can display a wide color gamut, but the 27GL650F-B gets brighter in SDR and HDR.

LG 27GL850-B/27GL83A-B

The LG 27GL850-B is slightly better than the 27GL650F-B. The 27GL850-B has a faster response time, resulting in clearer motion with less blur. The 27GL850 also has a better native resolution, so you can see more fine details in your favorite games, and it has an optional USB hub.

MSI Optix MAG273R

The LG 27GL650F-B and the MSI Optix MAG273R are very similar overall. The LG has slightly better ergonomics and better horizontal viewing angles, and it has much better accuracy out of the box. The MSI that we tested has better black uniformity, but this varies between units, so it might not be an actual difference.

ASUS TUF VG27VQ

The LG 27GL650F-B is much better than the ASUS TUF VG27VQ. Although both have 27 inch 1080p screens, the LG has much better viewing angles for when you need to share your screen, it can get brighter, and it supports HDR content. However, gamers might prefer the higher refresh rate on the ASUS, and it has a better contrast ratio too, but the response time is much better on the LG, resulting in clearer motion handling.

MSI Optix G272

The LG 27GL650F-B is much better than the MSI Optix G272 for most users. The LG has better ergonomics, as the stand has a good height adjustment range, and it can rotate to portrait orientation. The LG supports HDR, and it has better viewing angles. On the other hand, the MSI has a faster response time and much better reflection handling.

Acer Nitro VG271UP Pbmiipx

The LG 27GL650F-B is a bit better than the Acer Nitro VG271UP Pbmiipx. The LG has better ergonomics, and the unit we tested has better black uniformity. The Acer VG271UP has a higher native resolution though, so you can see more details in your favorite games.

Acer Nitro VG271 Pbmiipx

The LG 27GL650F-B is a bit better than the Acer Nitro VG271 Pbmiipx. Although they deliver similar performance overall, the LG has much better ergonomics, and it's officially certfied by NVIDIA as G-SYNC compatible, so FreeSync works automatically when connected to a recent NVIDIA graphics card.

MSI Optix G27C5

The LG 27GL650F-B is much better than the MSI Optix G27C5, but they have different panel types. The LG has an IPS panel, providing wide viewing angles. It also gets much brighter, supports HDR, has a much quicker response time, and better ergonomics. However, the MSI has a VA panel with a much better contrast ratio, higher refresh rate, and lower input lag.

Pixio PX7 Prime

The Pixio PX7 Prime is slightly better than the LG 27GL650F-B. The Pixio has a faster refresh rate and a higher resolution display, as well as slightly better ergonomics. The LG has an optional black frame insertion feature, resulting in slightly clearer motion if you don't mind flicker.

Gigabyte G32QC

The LG 27GL650F-B is a bit better than the Gigabyte G32QC for most uses. The LG has a higher SDR peak brightness, wider viewing angles, and a faster response time. The Gigabyte, on the other hand, has a higher contrast ratio that makes it better for dark rooms, a slightly higher refresh rate, and a bigger screen with a 1440p resolution.

MSI Optix G27C4

The LG 27GL650F-B is much better than the MSI Optix G27C4. Although the 27GL650F-B doesn't have as high a refresh rate as the G27C4, its IPS panel has much better viewing angles, significantly better peak brightness, and better color accuracy. The 27GL650F-B also supports HDR and has better ergonomics, but its contrast ratio is much worse than the G27C4, and it has a slightly higher input lag.

LG 32GN50T-B

Overall, the LG 27GL650F-B is much better than the LG 32GN50T-B. The 27GL650F-B has better ergonomics, wider viewing angles, and faster response time. It also delivers sharper images and text due to its higher pixel density. However, the 32GN50T-B has a VA panel that can produce deep blacks, making it a better choice for dark rooms.

ASUS TUF Gaming VG249Q1A

The ASUS TUF Gaming VG249Q1A and the LG 27GL650F-B are both 1080p gaming monitors. The ASUS delivers a better gaming experience because it has a slightly higher refresh rate of 165Hz and much faster response times. However, the LG's bigger screen makes it more ideal for productivity because it gives more space for multitasking. The LG also has wider viewing angles, better ergonomics, and gets a lot brighter to fight glare.

Dell S2719DGF

The LG 27GL650F-B is much better than the Dell S2719DGF for most uses, but the Dell is a bit better for gaming. The LG supports HDR, has better viewing angles, and an optional black frame insertion feature. The Dell has better ergonomics and a faster response time, and a higher native resolution.

ASUS VG279Q

The ASUS VG279Q is slightly better than the LG 27GL650F-B. The ASUS has much better ergonomics, with a 180° swivel range and a wider tilt range, so it's easier to place it in an ideal viewing position. Unlike the 27GL650F-B, the ASUS VG279Q doesn't support HDR, but this doesn't add much to the LG anyway.

It has okay HDR peak brightness with the 'Vivid' Picture Mode, but small highlights don't stand out as much as they should. The EOTF follows the target well until it reaches its peak brightness. As there's a slow roll-off at the peak brightness, it preserves details well in bright scenes.

The accuracy before calibration is decent. It doesn't have an sRGB mode to lock the colors to the sRGB color space, so some colors are oversaturated and inaccurate. The color temperature is also on the cold side, giving the image a blue tint, and the white balance is a bit off. Gamma is okay, but it seems to follow a 2.2 target instead of sRGB, so some scenes are too bright or too dark.

The LG 27GL650F-B works well with the PS5, but as expected for a monitor that doesn't have HDMI 2.1 bandwidth, it doesn't support 4k @ 120Hz or VRR. However, it downscales a 4k @ 60Hz signal, which results in a sharper image than a native 1080p signal.

The compatibility with the Xbox Series X is great. It supports 1440p @ 60Hz if you use the HDMI Override, but that disables VRR.

macOS Compatibility

The LG 27GL650F-B works well with recent MacBooks. There aren't any obvious issues like flicker in the desktop or games. Windows return to their original position when waking up the monitor from sleep, but not when you close the lid, which is a common problem when using a DisplayPort to USB-C adapter.

The LG 27GL650F-B has very few additional features. It can add virtual crosshairs to any game, and there's a 'Black Stabilizer' feature that adjusts the gamma in dark games to make it easier to spot other players in the shadows.
