Problem: Hantarex CT28 EV monitor does not sync

[Nodoyuna]

Hi

I have an Hantarex CT28 EV monitor

It's supposed to be a VGA/SVGA monitor, but I suspect it could also get 15KHz signals

I've tried the VGA input and it does work fine with both my Dreamcast and Atari Lynx II McWill VGA Out, but when I try to connect something 15KHz to the BNC inputs, the signal does not sync. I have tried SNES and N64 with RGB CSYNC cables made by retrogamingcables in UK, but they don't work

These are the connections on the back of the monitor



Any idea of what can I try? Thanks in advance

No idea. But I suspect 31khz only.

... their 15khz monitors seemed to have scart:

Looking at the discolouring on the your connection backplate it's possible they had different modules that allowed for different syncs/inputs.... Either that or that's just how they assembled these at different points in time.

...You might be able to hook something up manually if there's a tri-sync capable board+tube inside... But the chances of that isn't high imho.
