Our Verdict
LG 27GL850-B/27GL83A-B
Samsung Odyssey G50A S27AG50
The Samsung Odyssey G5 S27AG50 is similar for gaming to the LG 27GL850-B/27GL83A-B. The Samsung has a faster 165Hz refresh rate than the 144Hz on the LG, and it has a BFI feature that the LG doesn't have. The Samsung is also a slightly better choice for well-lit rooms because it gets brighter, and if you want to use it for co-op gaming, you can swivel its stand, which you can't do with the LG. The one difference the LG has over the Samsung is that it has USB 3.0 inputs to connect your keyboard and mouse, which you can't do with the Samsung.
