Our Verdict
Samsung Odyssey G4/G40B S27BG40
Dell G2524H
The Samsung Odyssey G4/G40B S27BG40 and the Dell G2524H are both entry-level 1080p, 240Hz gaming monitors. They both perform similarly, but the Dell has an overclock feature to raise the refresh rate to 280Hz. The Dell also has two USB ports, which the Samsung model doesn't have; these are useful if you want to connect your mouse and keyboard directly to the monitor. While the Samsung has HDR, it doesn't add much because of its limited picture quality.
