Found a HDMI cable, only like a foot long :roll: Connected Vsync... and nothing :(

Oddly my TV switches to EXT input (scart) even though I select HDMI from the menu :shrug:

There's a LED on the underside of the blue board, facing the DVI connector. You can see the LED's reflection in the connector. If it's steady red, it means the FPGA is picking up the expected 160256 cycles for each VSYNC. If it's flashing it means it isn't (which might mean the computer is doing something it shouldn't).

Check HALT on your CPU as well if you get no picture on another screen as well. Steady red means the GLUE is doing it's job at least.
