But I ran into issues with Xbox series x and ps5 often need a power cycle, I gave a number of different hdmi cables a try including optical ones no difference. And while playing gran tourismo picture would for a second of 2 get pixely I’m nit sure how really to describe it. There really is a market for some thing like this I just wished it worked always. It’s worth the price tag as do me it would save me form switching hdmi cables between, my atmos processor, projector and tv maybe a firmware upgrade will fix these issues Review: Awful and simply doesn’t work - Product is absolutely awful. Do not buy this product. The channel switching doesn’t even work. You have to turn the device on and off every time you want to switch channels. It also won’t connect to my laptop says the resolution won’t match and no matter what you do. it doesn’t work but most importantly, this is advertised with a remote and channel switching that simply does not work every time I switch from the PlayStation to the Xbox. The screen just goes black and I have to restart the device every time do not buy this. ## Features - 8K HDMI Matrix 4x2 Switch – Professional AV distribution solution featuring 4 HDMI inputs and 2 HDMI outputs, allowing multiple sources to be independently routed to two displays at the same time.
