X68000 Games Sound but no visual what can I do about unsupported resolutions?

Hi I have some games that seem to be booting into an unsupported resolution. I think from some games I've played 31kHz (VGA) resolution does seem to be quite common. Basically I was wondering if there was a way to get these games going visually in anyway? I heard some load into 15kHz, but can be switched? It could depend on the monitor? I haven't an original X68000 monitor. I wonder if those solved these kinds of issues more easily?

Anything would be greatly appreciated.

X68k likes to output in low-res 31khz. A lot of modern displays can not support such
low resolutions. The XPC-4 (Scan Convertor) was designed for this and works beautifully.

Hi again thanks a lot for your reply, it was greatfully appreciated. I checked out the XPC-4 Scan Converter but not sure where I can get one from. Maybe a store in Japan? Sorry it has been some time on this thread.
