Review on 🔀 HDMI Switcher 4k | GANA Intelligent 3-Port HDMI Switch with IR Remote | Supports 4K, Full HD1080p, 3D by James Ortega

I bought two of these TVs for my old Panasonic flat screen TVs. They are very easy to install, which is good as there are few details in the instructions. For example, I finally figured out that the switch will automatically connect to the last device that was turned on, and when that device is turned off, switch to another active source (if one is active). I share an HDMI port on my TV with Blu-Ray, Media Player and Roku 4. I don't have 4KUHD so I can't tell if the 4K feature will work. For 1080p it works great. The unit has a USB power plug, I think to power the remote control because I accidentally unplugged it and the only thing that didn't work was the remote control. Which reminded me that the USB power plug is short. I'm thinking about installing/gluing a switch on the back of the TV closer to the USB port. The remote sensor has a long cable so it can be placed in front of the screen. The remote itself is tiny and I keep losing it, but I've found that with the auto toggle feature, I can just turn off all devices and then turn on the device I want to use. I found my connection to the CCTV didn't like the switch, I don't know why, so I gave the CCTV the HDMI port my Roku 4 used and connected the Roku 4 to the switch. He had no problems. I have the same setup on a second TV but with only two devices (the TV has 4 HDMI ports while the first TV only has 3). It's definitely worth it for the price if you have more devices connected via HDMI than ports on your TV.
