Macintosh IIsi - VGA Video?

[Stephen]

Is it possible to get VGA video out from a stock IIsi? I’ve tried a DB15 to VGA adapter on multiple LCD monitors without success.

What’s the trick here? Alternatively, I have a RGBtoHDMI; maybe this is a better option?

The VGA monitor config is not available on the IIsi, best to select something like "Apple Macintosh Color Display" or any of the monitor types here without the '*'

and hope the monitor can do composite sync / sync on green

You can get VGA out of a IIsi, but some DB15 converters won't work. None of the ones with no DIP switches would work for me. The only one I've gotten to work is a Griffin MacPnP. IIRC, you configure the switches for "plug and play" and it works. They come up on eBay occasionally.

the ones without dipswitches are usually wired for multisync which doesn't work on all Macs. Just get a VGA adapter with the dipswitches instead of playing with unknown variables.

Thank you everyone, I used Alex Labs DB-15 to VGA adapter and after toying with a few different monitors I got this to work.

My IIsi display with no problem through my homemade adapter to a Samsung SyncMaster 731BM. 640x480 on a 1280x1024 LCD isn't pretty, but it's usable.
