Our Verdict
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. However, it has wide viewing angles if you want to share your screen with others.
- Excellent response time.
- Great peak brightness.
- Great color accuracy out of the box.
- Low contrast ratio and bad black uniformity.
- Can't display wide color gamut for HDR.
Good monitor for office use. The LG 27GL650F-B has wide viewing angles, great peak brightness, and decent reflection handling.

Popular Monitor Comparisons
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.
The LG 27GL850-B/27GL83A-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.
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.
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.
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.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
