Our Verdict

KOORUI S2741LM

KOORUI S2721PM

The KOORUI S2741LM is better than the KOORUI S2721PM. The S2741LM's dual mode feature and higher native resolution deliver a sharper image with smoother motion. It has better connectivity, with two HDMI 2.1 bandwidth inputs that allow it to take full advantage of recent gaming consoles, and it has a built-in USB hub with a KVM switch.
