Review on TESmart HDMI 4K Ultra HD 4X1 HDMI KVM Switch 3840X2160@60Hz 4:4:4 With 2 Pcs 5Ft KVM Cables Supports USB 2 by Craig Waters

Overall this is an excellent product and I use it to get a perfect 4:4:4 3840 x 2160 @ 60Hz picture on my 40th birthday - Obtain inch Samsung TVs. For 10-bit color I only get 30Hz, but my TV has a limitation, so I'm not sure if this set is the problem. I've seen other reviewers complain that it doesn't come with any cables - I used to have the Iogear KVM which came with all the cables which seems like a good idea but then again given the price, the I paid for it and the fact that other cables are quite cheap to buy makes me very happy. The trick is that you can actually buy any size cable you want and mix and match as you like. The cables were good quality and I paid about $40 for them and if I have a remote computer I can use it with a accommodate a few of very long cables. As you can see in the image I shared, I use a pair of 1ft USB and HDMI cables for my laptop and Mac mini, and longer 6ft cables for my desktops. Also, the box works great mixed with Linux, Windows and Mac. Because double-tapping the scroll button and then 1,2,3,4 works fine, I rarely use the Select button or the included remote. I liked the 4 iogear box select buttons I had before and also the fact that you could independently select where the sound was coming from - in fact the TEsmart people were able to add this as a feature for newer boxes - sometimes it's good to use a computer. but always get sound from the other, but it doesn't matter, the sound also works fine with HDMI from all the computers/OS I use.
