Check in early startup, or maybe with a program like Scout or SysInfo, is the card detected?  (not sure if video slot is scanned by those utilities)

And actually instead of the $5 for a CRT; maybe I'll just get the Amiga display to VGA cable.  Is there some reason that would be inferior?


If you're talking about just converting the 23-pin output to a 15-pin (VGA style connector), this isn't the same as scan doubling to 31Khz. It will only be 15Khz. Very few modern monitors will support it (and only a few screenmodes).

If you want to display native Amiga output on a modern monitor, why not just get an Indivision?

I've tired it on like 6/7 monitors one of which was a TV, but I'm in the US.

Thanks Paul; the manual also mentions that mono/Amiga display port connections don't interfere.  But i had missed that at first.  I've gotten a bunch of monitors at this point, the last of which - a Dell E773c has a vertical frequency scanning range that starts at 50hz.  Unless I'm misunderstanding the vertical frequency scanning range thing on the E773c (like unless that doesn't mean it supports 50hz, but I think it means that it does) I think that's a definitive failure with the card.  The E773c senses that its VGA cable is connected but otherwise gets no signal.

Why are you trying to get 50Hz?  You're in the US, get it working at 60Hz (NTSC) before you muck around with PAL settings.

IMHO if you've tried it with seven different monitors and none of them produce a picture (and you've confirmed that the monitors and cables otherwise work), the card is probably toast.

What does that mean 5v 100uf, then?

It's an electrical measurement.

Could I be misunderstanding the purpose of all this?  I just wanted a higher resolution display mode.

Get a real graphics card.  Or even an Indivision ECS offers several additional higher resolution modes (HighGFX, SuperPlus, HD720).
