I have been having intermittent issues connecting a NUC6CAYS running Windows 10 to a Vizio e70-e3 using the HDMI port.
Initially, I had video through but no audio before updating to the current Intel video/audio driver software. Now the screen goes black inconsistently, and at times the NUC loses full connection to the TV. I can only bring the NUC's display back by moving to a new HDMI input and back to the NUC.
My apologies for the inconvenience.
Let's try updating the current HDMI 2.0 Firmware version to the latest, please find the file here: https://downloadcenter.intel.com/download/26609/NUCs-HDMI-2-0-Firmware-Update-Tool-for-Intel-NUC-Kit... Download HDMI 2.0 Firmware Update Tool for Intel® NUC Kit NUC7i3BN, NUC7i5BN, NUC7i7BN, NUC6CAY, on the same .zip file you will find the instructions to update the version.
Please let me know the results.
