KYStar S2 DVI LED sending card
The KYStar S2 converts a DVI video signal from a computer or other source into data for compatible LED receiving cards. It has two Gigabit Ethernet output ports and a stated capacity of 1.31 million pixels.
Resolution, audio and configuration
EDID management supports custom input resolutions. The maximum width is 4,000 pixels and maximum height is 2,000 pixels, subject to the total 1.31-million-pixel capacity; these separate limits do not mean a 4000 × 2000 screen is supported.
A 3.5 mm stereo input supports audio transmission with a compatible multifunction card. USB Type-B provides PC control. Backup-data storage supports one-click repair, and the specification also lists color reproduction and reverse-polarity power protection.

Frequently asked questions
Can the S2 drive a 4000 × 2000 screen?
No such combined capacity is specified. Width and height are separate limits, and the total load must stay within 1.31 million pixels.
Does the S2 have HDMI input?
The specification lists one DVI-D video input, not HDMI. Check the source output and required signal connection before selecting the card.
Does the S2 transmit audio directly to speakers?
It has a stereo audio input for use with a compatible multifunction card. The specification does not describe a direct amplified speaker output.
Does the PCI slot carry the video signal?
The PDF describes the PCI slot as a 5 V power option. Video enters through DVI-D, while USB Type-B is used for PC control.
