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

No Amazon.com offer for the DXchip ZX-KVM8401B002, four-computer HDMI switch with an EDID emulator on October 26, 2026: it may not be buyable in the United States, which is the first thing to weigh against anything below.

The questions that come up before an order

Why does EDID emulation matter?

It keeps each computer believing its screen is still connected when you switch away, so windows do not jump around on return.

Can the AK700 drive HDMI screens?

Its page says it has no HDMI socket; DisplayPort-to-HDMI adapters may work for some setups, but the page does not promise it.
