Auto Downscaling & Auto Converting
This splitter supports independent auto downscaling and auto converting on all outputs. Before downscaling, it compares the EDID of all connected display devices and selects the minimum resolution to downscale and output. Examples of supported scenarios:
An 8K source connected to an 8K TV and a 4K SDR TV will bypass 8K HDR to the 8K TV and automatically downscale and convert to 4K SDR for the other output. A 4K source connected to an 8K TV and a 1080p SDR TV will bypass 4K HDR to the 8K TV and downscale/convert to 1080p SDR for the 1080p TV. A 1080p source connected to a 1080p DVI TV will output 1080p with no audio (DVI limitation).
Note: Downscaling will not work in the following conditions: (1) The input source is 8K DSC format. (2) The resolution of the input source is not supported by the splitter.
