Nifty!
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

Works great, including HDMI timecode
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.

Worked great to split and sync several TVs
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

Better than a daisy chain
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.

Can not do multiple resolutions at the same time
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
