How to Correctly Identify 4K60Hz

With the introduction of 4K and HDR (High Dynamic Range), the AV industry has been flooded with various signal types that may not be supported by your distributed system.

​Does your device say 4K60Hz, yet still no signal?
Is you device “full 4K”?

The SIX-A & SIX-G Test Suite

​The truth is, some devices cannot handle higher bandwidth 4K (4K60Hz 4:4:4 8Bit/18G or 4K60Hz 4:2:2 12Bit/18G). Using a 4:2:0 Chroma manufacturers can produce “4K60Hz” devices that are only handling 50% of the color information, as well as not displaying full HDR (4K60Hz 4:2:0 8 or 10Bit/(9G). Leaving customers with a choice to use only a few select 4K formats. For years manufacturers have been hiding behind this vague specification affecting switches, extenders, and even HDMI cables. Looking for specs that include 18Gbps or 4K60 4:4:4 with HDR, help notate a wide open, high bandwidth 4K signal. AVPro Edge provides many 18Gbps solutions, including all of our 444 extenders and AUHD products, that ensure the best video quality for your customers. Murideo, trusted in HDMI testing and troubleshooting, also provides tools to help confirm correct signaling with the Fox & Hound Testing and Troubleshooting Kit and the SIX-A Analyzer & SIX-G Generator Test Suite.
