Our Verdict
LG 27GR75Q-B
Samsung Odyssey G50D S27DG50
The LG 27GR75Q-B and the Samsung Odyssey G5/G50D S27DG50 are 1440p 27-inch gaming monitors. Both monitors are similar, and you may prefer to get whichever is less expensive. However, the Samsung is better if you plan to use the monitor in a bright room, as it gets much brighter.
