Review on NEWCARE 4K HDMI Splitter 1x3 - Supports 4Kx2K, 1080P, 3D, HDR, DTS/Dolby TrueHD - for Xbox PS5/4 Fire Stick Roku Blu-Ray Player Apple TV - HDMI Cable Included - NOT Extendable by Kyle Awasthi

I wanted to mirror the Roku output to a TV in another room. Works perfectly. I haven't had any of the issues that some others have reported with blank screens, no sound, etc. The resolution and aspect ratio on both TVs are fine. The only issue I had was that I placed it next to the Roku at first and it must have had RF sync noise or something because it was killing the Wi-Fi on the Roku. Roku Wifi was still a little iffy given that device was just a foot away from it. Now it's at 3 feet and there are no problems. The LEDs are brighter than they should be, not quite bright like a laser cat toy, but you don't want to look at them. But where I don't see it now, so it doesn't matter. I don't know if I'll ever use the third exit, but it's nice to know it's there just in case! I also liked that it includes an AC adapter so you don't have to rely on an external device to power it, no need to look elsewhere for a power source, etc.
