Original product photographs include 550D-series and 550DS-labelled views. They do not confirm that the SDI expansion module is included with the base model.
Frequently asked questions
1. Does the base LED-550D have an SDI input?
SDI is an expansion option. The manufacturer identifies the SDI input and loop configuration as LED-550DS.
2. Can the LED-550D display two pictures?
Yes. The listed functions include dual-picture display, with image adjustment and switching controls.
3. Can I set a custom output resolution?
Yes. Check the exact resolution and refresh rate against the output specification. Separate width and height limits should not be combined into an assumed maximum timing.
4. What should I provide when replacing an existing processor?
Provide the screen pixel dimensions, input connector and timing, downstream sending equipment, current output settings and any expansion-module requirements.
