Sorry for the delay, but we have had some issues here internally with the connection.
With some TV’s you need to set the Ultra HD Color to “enabled” manually in the setting of the TV for that HDMI2.0 port.
Please set the color depth to 8bpp / 10 bpp in your pc system.
Please do make sure to use an HDMI cable that has capacity to do 18Gbps (or HDMI2.0).
(like our CAC-1310; http://www.club-3d.com/index.php/products/reader.en/product/hdmi-20-high-speed-4k60hz-uhd-cable-.html )
If you would still need the firmware update please send us an email at [email protected]
