EDID నియంత్రణ
The EDID (Extended Display Identification Data) switch on the front panel allows you to manage the communication between the source and displays for optimal compatibility. Adjust the switch based on your setup requirements:
- దానంతట అదే: The splitter automatically detects the best EDID settings from the connected displays.
- కాపీ: The splitter copies the EDID from Output 1 to all other outputs. This is useful when all displays are identical or when you want to force a specific resolution/audio format.
- 5.1CH / 7.1CH: Forces the audio output to 5.1 channel or 7.1 channel, respectively, for compatible audio systems.
4K to 1080P Downscaling
The UHDS-104A features individual switches for each output (1-4) to enable or disable 4K to 1080P downscaling. This is particularly useful when connecting a 4K source to a mix of 4K and 1080P displays. By enabling downscaling for 1080P displays, you can ensure they receive a compatible signal while 4K displays receive the full 4K resolution.
- పై: Enables 4K to 1080P downscaling for the respective output.
- ఆఫ్: Disables 4K to 1080P downscaling for the respective output (passes through original resolution).
