DVI sending for a D90-based LED display
The Sysolution S20 sends a DVI video source to an LED receiving-card system through two Gigabit Ethernet outputs. It provides adjustable image positioning, resolution readback and USB-based configuration/cascading functions for building the screen layout.
Start selection with the D90 receiving-card match, the screen pixel count and each port’s assigned load. The original resolution-mode list is retained below, but it should not be confused with the card’s 1.3-million-pixel LED capacity. Verify the module scan configuration and 5 V power connection before installation.

Frequently asked questions
How many pixels can one S20 sending card control?
One S20 is listed for 1,300,000 LED pixels in total, with a limit of 650,000 pixels per Ethernet port. Check both the overall screen layout and the load assigned to each output.
Which receiving card is listed as compatible with the S20?
The product information specifies the D90 receiving card and LedSyncSet software. Verify the actual receiving-card model and LED module configuration when replacing a controller.
Is the S20 an asynchronous USB media player?
The S20 is described as a DVI synchronous sending card. Its USB function is listed for screen configuration and cascading sending cards; standalone video or image playback from a USB drive is not documented.
Do the listed resolution modes increase the LED load beyond 1.3 million pixels?
No. The original specification lists several resolution modes separately from the 1,300,000-pixel sending capacity. Do not treat a listed mode as proof that the full mode can be displayed at native LED resolution by a single card.
What voltage does the S20 require?
The listed working voltage is 5 V and maximum power consumption is less than 4 W. Use these values when checking the controller power connection; they are not specifications for the LED modules themselves.
