Can turn off HDCP by DIP switch compulsory




Downscaling Capability

1: “By-PASS” status: it will pass through whatever from inputs to outputs without any processing
2: “AUTO” Status, rules as below:


2.1 : If the source is 8K, the displayer is 4K, then it can downscale to 4K

2.2 : If the source is 4K, the displayer is 1080p, then it can downscale to 1080p


3: Scale limitation


3.1 : Can’t downscale from 8K to 1080p, If the source is 8K, but the displayers, Max supports 1080p, it will have black screen; But, if the source is 4K, the displayers, max support 1080p, it will output 1080p;

3.2 : Can’t support 720p or lower resolutions.
