bought this specifically for my man cave. Seamless switching from one feed to another is instant with zero lag. I wish I could program the function buttons on remote, but other than that works great.

This switcher has a variety of modes that allow this to function as a multiviewer, video wall controller, or a standard matrix switch. 4K30 inputs work, but I need 60Hz refresh, so I run this at 1080p60. It works great with my 1080p sources as a matrix switch, and I like the option to run in other modes if needed.

I’m hoping that I can revise this review if someone from the company can correct this issue. The description clearly shows that this supports video wall functionality - which is why we purchased. The software that is included on the device to control the video wall was different than what was provided in the instructions and was missing the “video wall” tab. If someone from the company can please correct this would be appreciated - otherwise it’s going to be returned

This product should be removed by Amazon for false information. There is nothing 4K about this device.

The media could not be loaded. This is an excellent matrix switch. It switches between 8 inputs and outputs easily with the remote control or by the front panel. It has a lan connection as well as a serial input for more advanced configurations. I simply use mine as a switch using the remote control. It's nice to be able to send any input to any of up to 8 monitors. Note that if you are planning on using this in a quiet office that it's going to be a bit loud. This has a fan that is fairly loud. I think this may have been designed for more of a commercial environment. I have a 4x4 version of this which is silent and has no fan. I'm going to swap the fan out for a quieter Noctua fan or similar. Other than that, this thing is super easy to use. Just punch a button for the input and a button for the output for basic use. More complex setups can be configured.

Great addition for my 2x2 video wall.

I have experienced a smooth and reliable experience with this display matrix switch and its ability to route multiple sources to different displays without delay is impressive. My setup includes various devices, yet the switch handles transitions flawlessly and the web interface makes controlling it straightforward. I appreciate the audio extraction feature, which integrates well with my sound system and the remote control adds convenience for quick adjustments. My entertainment space feels organized and professional and the switch’s consistent performance enhances my viewing sessions.
