ATEN CS1944 (2 Computers / Dual Monitor / DisplayPort KVMP Switch) Review

The ATEN CS1944 is a 2-computer, dual-monitor DisplayPort KVMP switch with 4K@60Hz support and a 2-port USB hub for extended-desktop setups.

This is ATEN's answer for anyone running two machines across two monitors who refuses to give up 4K at a full 60Hz, a spec plenty of cheaper dual-monitor switches still can't hit cleanly. It's not to be confused with the IOGEAR GCS1944, a completely different competitor product despite the similar-looking model number, and it sits below ATEN's own CS1924M in port count while matching its DisplayPort focus. Compared to the JCYMELE VP-SW273 already in this catalog, the CS1944 trades that unit's 144Hz ceiling for a more business-oriented, non-gaming feature set.

True Dual-Monitor 4K Switching

Both monitors switch together as a matched pair between the two connected computers, keeping an extended desktop layout intact instead of forcing single-display switching.

EDID Emulation for Clean Boot-Up

Built-in EDID emulation means both computers see valid display data at all times, avoiding the black-screen or wrong-resolution issues that plague cheaper KVMs when a monitor is switched away.

Comparison to Alternatives

Versus the IOGEAR GCS1944H — that's a 4-port dual-view HDMI switch with more computer inputs, worth it for a busier desk. Versus the ATEN CS1924M — that steps up to 4 computers with DP/HDMI flexibility, worth it if two machines isn't enough.
