SplitDeck, 1x2, 2 port 4K HDMI Splitter
The Splitdeck HDMI splitters support full HDMI 2.0 specs, meaning resolutions up to 4K@60Hz, 4:4:4 Chroma, and HDR. This means the SplitDecks can send a signal with those specs to 2, 4 or 8 HDMI displays.
Note: All SplitDecks are HDCP compliant which means that they do not strip or bypass HDCP. The SplitDecks support all versions of HDCP up to HDCP 2.2.
4K@30Hz VS 4K@60Hz
The main spec to look for when trying to find a true-HDMI 2.0 splitter (also including HDMI 2.0a and HDMI 2.0b) is the bandwidth spec-- it should be 18 Gbps. If an HDMI splitter passes this bandwidth, it can achieve full 4K 60Hz 4:4:4 chroma.
solve the cable TV problem
My only complaint is that it had no manual or any sort of explanation of its functionality. That being said, I went to their website and used the live chat support and got all the information I needed.
