Hello friends, I'm using a Digital I/O Board v1.2 with a "Vention HDMI to VGA Adapter" and a VGA to Component cable, the image is apparently ok, but the image is climbing vertically without stopping, does anyone have a solution?

If it's just a VGA to component passive breakout cable, you don't have any sync signal passing through to the TV. The H/V sync from VGA is just being ignored by a breakout cable. You need to get Sync on Green into the signal of the green (luma) cable somehow, which usually involves some kind of active circuit.
The Mister analog I/O boards provide SoG function, which is usually the easiest way to do that. There doesn't seem to be any way to have the Mister add it to its own HDMI out. Some more knowledgeable people might be able to help you with another approach. In theory an HDMI->component converter should do the job but some have had trouble with that too.
