Hello all,
Tried to test a MVS board on sale at a game meeting, but got only distorted picture :(
The setup was : Jamma connector, ATX power supply, PSOne screen with RGB & Csync inputs (works very well with MSX and Megadrive from RGB lines).
But picture was totally distorted and out of sync. Sometimes random squares like [] mixed with out-of-sync picture.
I checked many times all pinouts, cables, connections, voltages (with board on, all ok +5 and +12v)... but... nada... so i returned it
Has anyone experienced similar problems with this board ?
The sync and RGB signals from the MVS are very strong and will overwhelm many monitors. I can't say for sure this is your problem, but I had similar issues with many displays.
I used 1k pots from rgb lines but the sync was directly wired in the test ::)
Is there any method or circuit to correctly use the MVS on displays you mentioned ?
Thanks
