This is the second Ezcoo video product that I have, I was impressed by the first one so I thought I'd give this 2-1 KVM switch a try.
This switch is well built, with a metal case. It comes with a power adapter that securely screws on to the box, IR remote control, mounting tabs (with screws), two pieces of Velcro, and two USB3 (type-A) to USB3 (type-A) cables (1.5m) and a manual.
The KVM switch has 2×HDMI2.0 inputs, 1×USB2.0 input, 2×USB3.0 inputs, microphone input, 1×HDMI2.0 output, 2×USB3.0 outputs (with cables), audio out (headphone jack), front IR window, input switch, and a USB (micro) jack for firmware updates (or control).
I have had no problems passing any HDMI video / audio standard through this KVM switch, including DolbyVision 4K@24Hz & 1080P@60Hz, HDR 4K@30&24Hz, HDR 4K@60Hz, HDR 1080P@60Hz, Atmos, Dolby-MA7.1, DTS-HD7.1, PCM 7.1, & PCM 2.0.
I did have a weird glitch with my PS4 while switching from PCM 2.0 TO PCM 7.1 (stayed at 2.0), it was ok after I power cycled the switch.
Switching inputs between two PCs isn't super fast, but it's still reasonable (see video). I had no issues with switching between Windows PCs (or my Android phone), but my Mac would glitch every time I switched back to it (see video).
It seems that this switch will emulate the monitor for the inactive PC (input), which means that you don't loose your screen layout when you switch away from the PC. But as I mentioned, my MacBook looses the monitor for a brief moment when switching back (as if it was unplugged and plugged in quickly).
The USB devices will disconnect from the inactive PC, but this probably can't be avoided. (Just remember to eject any hard drives you have connected to the KVM box before you switch)
I had no problem using a wireless keyboard / mouse combo. The mic in and headphone out were seen on both Windows and Mac.
The front of the unit has a few fairly bright red LEDs and you can see another blue LED behind the button (if you look really carefully there is also another green LED hidden inside). I had no problem with the bright red LEDs, but they might bother some.
The remote control came with a battery and I had no issues with it either.
The KVM switch stays nice and cool in its metal case.
Hopefully they can resolve the Mac issues with a firmware update.
Note: This KVM switch doesn't like having devices hot-plugged! Either plug everything in with no power or power cycle the switch after you've connected all HDMI and USB out cables. (If you don't it may not work with one or both of the input devices)
Overall I think that this is a great little KVM switch and it would deserve 5 stars if not for the little glitches. 4 stars 🌟🌟🌟🌟
