Nano 31k Pandoras Box Sync Issue

Post by RKDE »

Hi

Another question... :D

I have been looking around for an answer on this. Why will a pandoras box 31k output not sync with a Nanao 31k tube through VGA?

Has anyone got this to work, are there certain versions that put out a proper 31k so a Tube can sync properly?

My 15k tubes seem to be going out and hope to use a 31k only tube.

Thanks for any info.

its probably to do with combined or separate sync wiring in the vga cable

I think output from your pandora's VGA port is not VGA(640x480, 31KHz).
It will be SVGA(800x600, 37KHz).
So Blast Monitor cannot sync it.

Not at the moment. I have a newer VGA cable

Hi

I see, that would cause it to not sync. I guess it needs an adapter of some sort.

Thanks

You could connect it to a LCD monitor and see what resolution it's outputting.

Syncs fiiiine to Naomi, but not to Pandora's Box.
