3 Ways to Extend Your Display on LattePanda Sigma

  1. HDMI monitor: via HDMI port(HDMI 2.1, Up to 4096 x 2304 @ 60Hz) -- for standard desktop usage
  2. USB Type C monitor or USB Type C to HDMI / DP Dock: via USB Type C port(DP 1.4a, Up to 7680 x 4320 @ 60Hz ) -- for standard desktop or mobile usage
  3. eDP Screen: via eDP(eDP 1.4b, Up to 4096 x 2304 @ 120Hz) -- for embedded application scenarios

HDMI

Note

The LattePanda Sigma supports HDMI 2.1, therefore, if you are using a display that supports 4K 60Hz HDR, it is recommended to use an HDMI 2.0b or 2.1 cable.

What You Will Need

  • HDMI Cable
  • TV or Monitor with HDMI Port

Installation Steps

  1. Connect one end of the HDMI cable to the HDMI port on the LattePanda.
  2. Connect the other end of the HDMI cable to the TV or monitor.

USB Type C

The USB Type C ports on LattePanda Sigma are both full function Thunderbolt 4. They both supports power, USB data, video and PCIe.

Thunderbolt 4 supports video output at up to 8K resolution or faster refresh rates, which is significantly higher than most other types of video outputs, and can help to reduce motion blur and provide a smoother and more responsive visual experience.

Thunderbolt 4 also supports daisy-chaining multiple devices together. You can connect multiple displays to a single Thunderbolt 4 port, without needing to use additional video ports on LattePanda.

Additionally, Thunderbolt 4 supports higher power delivery, which means you can charge your display devices while using the Thunderbolt 4 port for video output.

Note

One Thunderbolt 4 supports up to 8K resolution and 60Hz refresh rate, but only when connected to a single monitor and use a Thunderbolt 3 or 4, or USB 4 cable.

What You Will Need

  • USB Type C Display, or USB Type C / Thunderbolt Dock

  • USB Type C Cable

Installation Steps

  • If your display device does not have a USB Type C port, you will need to use a USB Type C Dock. Follow these steps to connect your LattePanda to the display device:

    1. Locate the USB Type C port on your LattePanda(there are two USB Type C ports on LattePanda Sigma, both of which can be used).
    2. Connect the USB Type C HUB to the USB Type C port of your LattePanda.

  • Connect one end of the USB Type C cable to the USB Type C port of your LattePanda. Make sure it is securely plugged in.
  • Connect the other end of the USB Type C cable to the USB Type C port of your display device. Make sure it is securely plugged in.

eDP(Embedded DisplayPort)

The LattePanda Sigma uses a 0.5mm pitch 40-pin connector for its eDP interface, which has 4 lanes and supports resolutions up to 4K and refresh rates up to 120Hz. This design allows for a power-efficient and high-bandwidth display connection while also enabling thinner and lighter device designs.

What You Will Need

  • 40-Pin eDP display, 40-Pin to 40-Pin eDP Cable

or

  • 30-Pin eDP display, 40-Pin to 30-Pin eDP Cable

In most cases, any display devices which have a 40Pin eDP connector and is powered by 3.3V is compatible with LattePanda Sigma and don't require additional drivers. The eDP connector of LattePanda Sigma has four lanes.
