J-Tech Digital HDMI Splitter 4K 60Hz 1X4 Multi-Resolution Output (MRO) HDMI 2.0 Splitter Supports downscale HDR HDR10 / Dolby Vision 4K@60Hz 4:4:4 HDCP2.3 2.2 (JTECH-4KSP4)

Works great with optical HDMI cables, and can also pass HDMI timecode. The USB C port also seems to be correctly implemented so it will work from USB C power supplies directly. I have only tested this at 1080p so far.

Used this to split a signal to 3 TVs and it worked great. Good resolution picture. Fairly easy to set up. Settings available to sync different TVs

I have two two Port splitters already and had to make a decision about daisy chaining, so I went in search of this 4-port. Price and performance are excellent.

It works perfectly. Just what i needed.

This will take the lowest resolution and spread it evenly if you turn the downscaler on. I was able to circumvent this by using only 1 port for my main 4k HDR TV then the second port goes to another splitter that can send 4k(not HDR apparently, that's why I got this one) as well as 1080 simultaneously. I have 3 TVs on one source. This is a bandaid work around using 2 splitters but it works

hasta ahora de maravillas

This stop working. Would not duplicate video and sound after a few months.

Well built and comes with a power supply. It's 5 volts. Passes video with no problems.

This nifty device really works as advertised. I have a FHD monitor and a 4K projector. And I need to use screen mirror. This device worked brilliantly
