I wonder whether it digitised the video signal and sent digital RGB data over the connector, or whether there were analogue video channels provided for such a device.

Also, in any case, whether any hobbyist hackers have built adapters to use their Game Gear as a monitor for anything else through the same mechanism. (A HDMI in adapter would be cool, if slightly ridiculous.)

it's fascinating, the game gear itself actually has a "TV Mode" that's activated by holding down a certain signal on the cartridge bus which bypasses the z80 and VDP and chucks a digital RGB signal and some kind of custom timing information straight to the screen
