Hi there,

I’m in the same boat as many others, so here’s my hardware combination:

Sony X930C 4K TV (updated firmware)
Intel NUC 5i5RYK (updated BIOS & all drivers)
CAC-1170
Monster UltraHD Black Platinum 4K HDMI cable (rated at 27 Gbps)

Since buying the Monster HDMI cable, I now have the option in Windows 10 to select 4K resolution at 60Hz refresh rate, so the cable was obviously a bottleneck prior to this.  However when I select it and the TV tries to display it, the screen goes black for a few seconds and then reverts back to the previously selected resolution.  The highest it will go successfully is 4K at 30Hz.

I have now sent 2 emails asking for the firmware update, but Marcel seems reluctant to send it … I’m not sure why.  He has responded with the standard troubleshooting steps, which I have followed with no success.  One glaring issue with the standard troubleshooting as I see it, is the need to change the colour depth to 8 bit.  Unfortunately, Windows only supports 32 bit depth, which has been the case since Windows 8 … so as far as I can tell, I don’t have the ability to change the colour depth to 8 bit as suggested.

I would love a solution … anybody … Bueller?
