Limited hdmi to scart wiring diagram - Consistent with nt rautanen’s pinout information at the amiga rgb port pin thirteen is “ground return for external clock allow”. Connecting that to blanking sign floor did not seem logical to me. Moreover, nt rautanen’s page particularly says that don't connect pin thirteen with pins 16-20 (video floor) on the amiga rgb port. I wanted as a way to hook up an amiga 500 to tv with respectable photo satisfactory for an upcoming gaming session. In place of using the awful composhite signal or the dreadful rf antenna cable i wanted something a whole lot higher because modern tvs don’t forgive low-exceptional video sign. In fact, flat panel tvs have a tendency to make old structures appearance without a doubt terrible. Low decision and sharp, pixelled snap shots (in opposite to e.G. Real life video) transferred using blurry and noisy sign, after which displayed stretched and processed on a hd panel. You realize it ain’t gonna be pretty! The exceptional manner to prevent the worst eyesores is to use excessive satisfactory video sign at the least.
As it seems stedman’s diagram is likely to do just that. It's far probable that maximum tvs and video display units with scart socket have all the ground lines at scart socket connected. I backed up this assumption with the tvs in our family the usage of a continuity meter. In other words connecting amiga rgb port pin 13 to any scart ground connects it with the commonplace floor (including the pins 16-20 in amiga rgb port). I built my cable in line with stedman’s diagram, except for the above referred to a13-s18 line. I also used the advised 220 ohm resistor in preference to the 75 ohms within the blanking / rgb mode choice sign (scart pin sixteen).
The most convincing diagram i found for such cable changed into at ian stedman’s website. Instead of blindly constructing wirings the use of diagrams discovered off net i like to pass reference matters. After having a take a look at amiga rgb port’s pinout one of the connections in stedman’s diagram became starting to appearance suspicious.
