The Amiga's RGB is always centred slightly off due to the sync timing being slightly different for composite / RF. Most TVs and monitors centre it fine but some have trouble, and adaptors tend to offer less flexibility than TVs themselves. For Workbench and system-friendly applications, use the Overscan prefs to drag the screen corners as close as you can to the actual screen borders. Many games will shift the graphics to the right anyway so hopefully they'll be fine too.
If not however, see if there are any adjustments on the adaptor. My Panasonic G10 plasma had a similar issue over SCART. It has a hidden service menu that I was able to use to adjust the horizontal position of SCART input and that fixed the problem. Such adjustments would have to be at the adaptor point in your setup however. As a last resort, something to introduce a tiny delay into the Hsync will fix it, but such a device is probably expensive if it exists... |

You can adjust the Workbench screen's position through Overscan prefs. Unfortunately, that doesn't affect any games.

idrougge - I had thought of that, but then I remembered that's only for Workbench
demolition - the A4000 has some jumpers that I'm not sure of what they do: - J500: Sync on green disabled/enabled - J501: LISA sync (2-3 closed is the only setting it lists, which is Default) - J502: DAC syncs on green/uses standard signal Would changing these make any difference? |

Anyway, glad you got it sorted and are happy. My next frontier is to get an Open Source Scan Converter. They look great and I have heard really good things about them. |
