Supports true 4K at 60Hz Not all 4K splitters are created equal. While some HDMI 1.4 splitters can achieve 4K resolutions, they'll only work at a 30Hz refresh rate. Other HDMI 1.4 splitters are marketed as 4K at 60Hz, but their color data is reduced to a lower 4:2:0 chroma subsampling.
Do all HDMI splitters support 4K?
No, you will want to look specifically at an HDMI 4K splitter. Today, most splitters and HDMI switches will support 4K – but not all of them. If you have an older splitter, it's less likely to support 4K. You will also need high-speed cables that support 4K resolutions too.
Do HDMI splitters affect picture quality?
Does HDMI splitter reduce quality? HDMI Splitters do not automatically reduce quality because they are copying a digital signal. But using lower quality hardware or a non-powered HDMI Splitter is less of a guarantee. Splitters used with very long HDMI cables may have signal quality issues due to the cable length.
