JCYMELE SW273 4K144Hz DisplayPort KVM Switch Review

The JCYMELE 4K@144Hz KVM Switch is a 2-computer, 2-monitor KVM switch using DisplayPort 1.4 with verified 4K@144Hz support, G-Sync passthrough, a metal housing, and a dedicated DC power adapter for gaming setups.

Named the best gaming pick specifically because of verified 4K@144Hz support and G-Sync passthrough, HDMI 2.0 KVMs cap at 4K@60Hz, which independent testing confirms is not enough for high refresh rate gaming. The only option in comparable roundups that handles high refresh rates through DisplayPort 1.4 specifically, since DisplayPort is independently confirmed as the most capable video standard for PC KVMs because it supports higher refresh rates at 4K without compression that HDMI 2.0 requires. The metal housing and reliable G-Sync passthrough make it the right call for gaming-first dual monitor setups specifically, where signal reliability under high refresh rate load matters more than in standard office use. A dedicated DC power adapter, rather than bus-powered USB draw, is specifically recommended for demanding setups like 4K@144Hz, bus-powered KVMs pulling power from computer USB ports work for 4K@60Hz but can be unstable at higher refresh rates.

Metal Housing and DC Power

The metal housing and reliable G-Sync passthrough make it the right call for gaming-first dual monitor setups specifically, where signal reliability under high refresh rate load matters more than in standard office use.

Comparison to Alternatives

Versus the Hearvo HDMI KVM Switch, that HDMI 2.0 unit caps at 4K@60Hz, insufficient for this JCYMELE's specific high-refresh gaming use case. Versus the UGREEN 8K DisplayPort models, those push even further to 8K@60Hz or 4K@240Hz for buyers with certified DP 1.4 cables under 2 meters and displays capable of those extreme specs.
