Hi everybody! tired of wavy and small image at a little TV I have, I'm trying now to watch replica 1 image at my amstrad CTM-644 monitor. It has not AV input, only RF, so I made an "interface" with an UM1233 modulator (from an old zx spectrum).
I connected to replica video output and I almost see something, playing with tunning and vertical hold... but I didn't get
an useful image. what could be the problem? maybe something about PAL-NTSC compatibility (monitor has PAL input). I wondered about signal from replica too, it could be too strong or too weak for this modulator
if anybody knows about video modulators, please help me
