# LVDS Encoder

Integrated Device Technology V103 LVDS encoder - IDTV103

Tegra 3 only supports a parallel interface or SPI LCD, DVI, an HDMI HDTV, RGB monitor or a MIPI DSI LCD.

Surface RT uses a LVDS Display. Therefore an translator is needed.

They used a **Integrated Device Technology V103 LVDS encoder**[\

The converter is transparent to the SoC and does its job without any configuration.\
It only needs power and the PowerDown pin set to LOW

## GPIOs

B2 - power down

If we set this pin to LOW from UEFI Shell new information can't be send from the SoC to the display. In this case the image fades out.
