Quote from: JonB on 10:37, 01 February 19I think the VGA sync frequencies are too high for the Amstrad monitor. Much easier to split the composite sync from the Pi. Cheaper, too.
Quote from: Token on 04:09, 02 February 19You can get 15KHz with a PI and a cheap HDMI to VGA converter + the 240p config file. I added a DIN6 for my CTM644 and GT65. There is also the GERT VGA 666 module (cheap as well) but I prefer the first solution.
Quote from: Token on 16:08, 02 February 19I've seen that too late in the night that you tested it yet I have the GERT 666 as well, it's nice even if I have read that it could reduce the color palette (6-bits per colour channel) I haven't see it (and I have use it as video player too) The good point is it doesn't get hot like the HDMI-VGA converter. If I didn't have problem with it I'm thinking to use a heatsink like I did on a wifi dongle.
Quote from: JonB on 20:27, 31 January 19More complex. The Pi has a composite video output but the PCW needs separate sync / luminance (video) signals.You need a sync splitter. There are some circuits for this but I couldn't find one that takes composite and gives CSYNC and VIDEO output, yet.
