ROFAVEZCO EZ-SW41H21-KVMU3P, four-computer HDMI switch with hotkey and infrared control vs MLEEDA four-computer HDMI switch driving two screens, with RS232 control

8K on one screen, or 4K across two?

By

Both switch four computers over USB 3.0 with three switching methods. The ROFAVEZCO EZ-SW41H21 uses HDMI 2.1 for 8K at 60 Hz or 4K at 120 Hz on one screen, with hotkey and infrared control, and supplies four USB 3.0 leads. The MLEEDA drives two screens per computer at 4K 60 Hz, counts four USB ports, names audio and RS232 among the shared connections, and supplies leads, a wired remote and a power supply.

A tick means one listing published something the other did not, or published a better figure. It does not mean the product is better, and the column is not a score out of anything: a maker who says less loses lines here without losing a comparison. The two verdicts below are where the page is settled.

Which of the two, for which household

ROFAVEZCO EZ-SW41H21-KVMU3P, four-computer HDMI switch with hotkey and infrared control

No Amazon.com offer for the ROFAVEZCO EZ-SW41H21-KVMU3P, four-computer HDMI switch with hotkey and infrared control on October 26, 2026: it may not be buyable in the United States, which is the first thing to weigh against anything below.

Take the ROFAVEZCO for one high-resolution or high-refresh screen shared between four machines. Neither of the two had an Amazon.com offer on October 26, 2026.

MLEEDA four-computer HDMI switch driving two screens, with RS232 control

No Amazon.com offer for the MLEEDA four-computer HDMI switch driving two screens, with RS232 control on October 26, 2026: it may not be buyable in the United States, which is the first thing to weigh against anything below.

Take the MLEEDA for a two-screen desk where four computers take turns, and where RS232 control from a script or a control panel is useful.

The questions that come up before an order

What is RS232 control for?

Switching computers from a control system or a script rather than a button — common in labs and AV racks.

Does 8K matter on a KVM?

Only with an 8K screen, or for 4K at 120 Hz, which the ROFAVEZCO also states.
