The DVI/HDMI question should be does GCBASIC support TFP401? No. I am sure it can supportted the driver would need to be written,
**DVI/HMDI raw signal generation from a microcontroller **
Implementing raw DVI/HDMI on an 8-bit microcontroller would be challenging due to the high data bandwidth and processing requirements of these interfaces.
Data Bandwidth: DVI/HDMI interfaces require high data rates that are typically beyond the capabilities of an 8-bit microcontroller.
An 8-bit microcontroller generally lacks the processing power needed to handle the encoding and decoding of video signals.
DVI/HDMI interfaces require a framebuffer to store the video data before it is sent to the display. An 8-bit microcontroller typically does not have enough memory to handle this.
A solution
The Adafruit product above uses an external HDMI/DVI module to interface to the compute device. The TFP401.
The HDMI/DVI module handles the heavy lifting of video processing and provides a simpler interface for a microcontroller to control.
Have a look at https://www.surenoo.com The product from Adafruit is very likely to be supplied by Surenoo.

Does GCB support DVI/HDMI?
I think this is wrong question. Sorry.

We have worked with SureNoo. https://github.com/GreatCowBASIC/Help/blob/main/seven_inch_gcld/sample.adoc
This is a 7inch with Touch solution without the cost of DVI/HDMI.
