RE: Firmware CAC-1070

Hi Kahless, the biggest update in the last firmware (compared the the version that your Adapter will have) has to do with reading EDID info  coming from TV’s. This could be a problem mainly with Vizio tv’s. I do not expect you to need the firmware update looking at your hardware.

Here’s my standard checklist:

* Color Depth (often default set to 16 bits or even 32 bits) need to be set to 8 bits (when running 4:4:4).

What are the 4K formats supported by the adapter ?

* Make sure the HDMI cable you are using can do HDMI2.0 or 18Gbps.

Sound a bit “easy” but many cable do actually not support the full bandwidth, certainly  not cables longer than 3 meters …

* On many TV’s you need to turn on “UHD Color” or “Advanced (Color) Setting” manually in the settings of your TV for the HDMI port to which your pc is connected.

* Also it could help when connecting 2 screens, to set the screen connected thru the Adapter as second/secondary screen

* I strongly advise you to make a custom resolution, set resolution to 3840×2160 at 60Hz and set Timing standard to CVT-RB (reduced blanking)
