Adafruit DVI Sock for Pico - Works with HDMI Displays
Passive DVI/HDMI output add-on for Raspberry Pi Pico using 220-ohm series resistors on GP12–GP19 TMDS pairs. No active components; requires RP2040 PIO and overclocking. Video only, no audio. Solders directly to Pico or connects via jumper wires.
