Does not support 1080p at 144hz as advertised. First thing I did was check the manual at it only says it can support 1080p at 60hz was the final piece to my setup needed. Disappointed I’m sure it works fine for others speeds but it was falsely advertised. Need 1080p at 120hz.

Works as I expected. Have not had any issues with it. There's a slight delay when clicking the button to change inputs, but otherwise no issues.

Item: Suceem 4K HDMI Switch, Bi-Directional HDMI Switch Splitter 2 in 1 OutThis is HDMI switch does the job it sets out to do! No fancy add-ons or signal processing, just a simple HDMI switch that turns 2 inputs into 1 output. It was really easy to use and setup and did the job perfectly!

Ordered this so that I could switch between my PS5 and my Nintendo Switch on my gaming monitor. Simple task completed with simple tech. Worked right out of the box with no issues. Seems like a solid choice.

So the way this device works is nice... it's essentially "dumb". Basically, there are two ports on one side, and one port on the other. The button simply switches which of the two ports is wired to the single port on the other side.It then acts as a pass-through. In other words, The laptop or device connecting to HDMI doesnt "know" its going through a switch, it just lets the signal connect through.This means it's bi-directional. You can either have one source, and toggle between two different output displays.ORYou can have two input sources, and toggle between them for a single display.Pretty neat, and works fine for me!
