Understanding DisplayPort Alternate Mode

What is DisplayPort Alternate Mode?

DisplayPort Alternate Mode (DP Alt Mode) is an extension of the USB-C standard that allows USB-C ports to transmit DisplayPort video signals. This technology enables a single USB-C port to function as both a data transfer port and a video output port. The DP Alt Mode leverages the high bandwidth capabilities of USB-C to deliver high-resolution video and multi-channel audio to external displays without requiring additional adapters or cables.

Technical Specifications of DP Alt Mode

The technical specifications of DP Alt Mode are defined by the Video Electronics Standards Association (VESA). Key specifications include:

• Bandwidth: DP Alt Mode supports DisplayPort standards, offering bandwidth up to HBR3 (High Bit Rate 3), which can handle 8.1 Gbps per lane, totaling 32.4 Gbps for four lanes. This bandwidth supports resolutions up to 8K UHD at 60Hz with HDR.
• Video Standards: DP Alt Mode supports various DisplayPort video standards, including DisplayPort 1.2, 1.3, and 1.4. The specific version supported depends on the device and its implementation.
• Audio Support: DP Alt Mode supports multi-channel audio formats, including Dolby Atmos and DTS:X, providing a high-fidelity audio experience when connected to compatible displays or audio systems.
• Power Delivery: USB-C ports supporting DP Alt Mode also support USB Power Delivery (USB-PD), allowing the connected device to charge while simultaneously outputting video and audio.

How DP Alt Mode Works on Android Devices

On Android devices, DP Alt Mode is implemented through the USB-C port. When a compatible Android device is connected to an external display via USB-C, the device detects the display and switches the USB-C port to DP Alt Mode. This allows the device to transmit DisplayPort video and audio signals directly to the display. The Android operating system provides the necessary drivers and software support to manage the video output and ensure compatibility with various display resolutions and refresh rates.

Benefits of Using DP Alt Mode on Android
