Review on Rybozen KVM Switch HDMI 2 Port Box with USB and HDMI, Share Keyboard Mouse Printer and HD Monitor, Support 4K HUD (3840x2160), includes 2 HDMI and 2 USB Cables by Jerry Forehand

This switch comes with 2 USB cables and 2 HDMI cables which is great. When I first connected the switch to my Samsung 4K monitor, home pc and work laptop, I was a bit disappointed because the monitor didn't accept video from the pc or laptop via HDMI. After playing around with it a bit I gave up and decided to order some high speed HDMI cables. The ones I ordered were 3 packs of 48Gb/s from Cable Matters here at Revain. They arrived the next day and I hooked them up. The problem with the video connection was fixed immediately. Hopefully the company that sells this switch will take note and update the HDMI cables that came with the switch. As for the included USB cables, they work great. If you have a wireless mouse and/or keyboard with a USB dongle, you can also plug that into the Switch and it will toggle without a hitch! Overall, the $30 Switch works great. I would give 5 stars if I didn't have to buy better HDMI cables.
