Auto Downscaling & Auto Converting

This 48Gbps 1x8 HDMI Splitter supports auto downscaling and auto converting on all outputs. Before downscaling it will compare all the EDID of the connected display devices and select the minimum resolution to downscale and output. For example:

In the example above, 4K is lower than the resolution of input source, so it will downscale and output according to the the minimum resolution of 4K SDR.

In the example above, 1080P is lower than the resolution of input source, so it will downscale and output according to the the minimum resolution of 1080P SDR.

Downscaling will not work in the following conditions:

  1. The input source is 8K DSC format.
  2. The resolution of input source is not supported by the splitter.

Note: If the source resolution is downscaled and converted to 1080P DVI according to the EDID of display devices, it will be output without sound on TV.
