Review on DupSee Splitter 1x2 HDMI 4K 1.4a Signal Distributor - Supports 3D, 4K, 1080p, Dolby, True HD, DTS-HD | CEC, 12 Bit Color | USB Micro-B Power Jack by Samuel Bowen

I bought this to replace my old splitter that didn't support 4K and I'm so glad I found it because not only does it support 4K but it's designed like a tank. It comes in an all-metal case. They're held together with real screws, not cheap plastic, which is a huge plus for me because I love things that are made to last. It's pretty easy to work with, you plug in HDMI on one side and it creates two precise outputs. which you can send to multiple recipients. It also accepts a 5V mini USB connector for power, which you may or may not need depending on your source cable. I'm using USB power for my setup because I'm using mine with an HDMI recorder that requires it. I only had one small problem. If your input source doesn't allow you to change the resolution, the default is 720. If my input source is a computer, streaming device, or Blu-ray, I can change the resolution to whatever I want in the appropriate menus. but when I use it with my iPhone or iPad I can't adjust the resolution so it ends up being 720p.
