A DisplayPort 1.4 MST to HDMI2.0/DP/eDP converter with embedded MCU is a kind of chip or device that can convert DisplayPort 1.4 multi - stream transport (MST) signals into HDMI2.0, DisplayPort or embedded DisplayPort (eDP) signals, and it integrates a micro - control unit (MCU). Take GSCoolink GSV2221 as an example, its relevant introduction is as follows2:

• Core functions and interface specifications: The DisplayPort 1.4 MST receiver supports a 4 - channel HBR3 rate (32.4Gbps), which can process 2 compressed or uncompressed video streams simultaneously. The HDMI 2.0 transmitter supports a TMDS 3 - channel 6Gbps rate (18Gbps in total), which can output 4K@60Hz (4:2:0) or 1080P@144Hz signals. The DisplayPort 1.4 transmitter also supports a 4 - channel HBR3 rate (32.4Gbps), which can retain the original DP signal.
• Power management: It supports the USB PD3.0 protocol, manages the power - supply negotiation through the CC pin, and can transmit up to 100W of power (20V/5A). It is compatible with dual - mode power supply of VBUS power supply and system power supply, optimizing the energy - efficiency performance in low - power consumption scenarios.
• Application scenarios: It is suitable for in - vehicle electronics, video - conferencing equipment, Type - C docking stations, DP to HDMI cables and other scenarios. For example, in in - vehicle electronics, it can convert the DP signal of a mobile phone or host into an HDMI output to the in - vehicle display and charge the device through the PD protocol.

In general, this kind of converter has the advantages of high - performance, low - power consumption and multi - function due to the integration of MCU, which can meet the needs of different display devices and application scenarios, and reduce the BOM cost and shorten the development cycle.
