You may have noticed that our RP2350 Feather has an FPC output connector on the end for accessing the HSTX (High Speed Transmission) peripheral. This new capability, not available on the RP2040, is specifically designed to allow the RP2350 chip drive DVI displays really easily! Historically you could use DVI on the RP2040 by mashing together some overclocking and a lot of PIO - it works but its quite hacky. The HSTX peripheral is streamlined, and doesn't require PIO or overclocking and there's a lot more RAM on the RP2350.
