HDMI Matrix ARC 4 In 2 Out 4K HDR EDID 4K7.1/5.1/COPY Switch with SPDIF L/R Audio Extractor - Down-Scale 4K to 1080P,D-o-l-b-y Vision Atmos in Sync,HDMI Switch 4x2 CEC HDCP2.2 4K60 4:4:4 IR Remote Ext

I am using the switch to switch between my work/home computer and an HD computer monitor and LG TV. It works very well switching between the computers and the computer monitor. However, there seems to be a slight incompatibility when switching the computers to the TV screen. If you look close, there are small flickering spots (individual pixels) in the image, but don't really notice this from a distance. There is likely an incompatibility between a computer and the LG TV when using this switch, and probably my fault for not noticing this in the documentation. The computers and TV work fine when directly connected.

I use one of these with a PS4 and AppleTV. It frequently fails to auto detect input and switch to it when I turn one of them on.

Everything works great, instruction booklet very clear, nice accessories with the IR extender and the wall bracket if you want to mount it. Remote is simple to use and a bonus is it works with universal remotes like logitech, just sync it up.

Very awesome little device for switching any of 4 HDMI inputs to any of the two HDMI outputs. It has an auto downscaler so you can still see 4K on one device and 1080P on the other output. Includes audio extraction from either HDMI output. Its great to have so many switches and settings on one hand, but on the other, you need to know what you are doing for the best results. Comes with mounting brackets and a nice remote. I havnt figured out what the RS232 ports are used for, but Im sure the manual says. Overall good device with a lot of flexibility.

It does what it says. I connected my 3 sources to it Apple TV, TiVo stream and my 3d player to my projector. It says Dolby vision enabled. I then run the 1080p output to my older avr for sound. If I didn’t have this device my projector would not be able to see the lldv Dolby Vision signal

I have been working with EZCOO starting on August 3, 2023 and continued to with a new remote and several testing requests. I replied to an email from support on September 6, 2023 that the unit still does not work and have not heard back from them.

I was having difficulties getting all my streaming devices working with my new sound bar and universal remote. The multiple inputs and outputs solved my problems.

I got this specifically to support 120fps out of my PS5 console and it works like a charm. The optical audio output also works great. Edit: Got a weird bug. When playing Street Fighter 6, the HDMI audio will suddenly cut-out mid-match (keep in mind the optical out still works fine). It will then slowly come back in 5 mins or so, but sounds super glitchy during that duration. I've done multiple HDMI configurations to troubleshoot this device with the TV and console, but all seem to function fine independently. Taking a star off because of this. About two months after purchase and I found the issue. This works totally fine with 1080p output from PS5, no audio cuts or distortion whatsoever, but those issues are prevalent at 4k resolution. I contacted customer support directly from their website, they didn't offer any help. Not sure if this is an exclusive issue for the PS5, but really sucks considering they advertise it towards that crowd anyway. Basically a paperweight for me now, very disappointed.
