Re: 3W3 to VGA

Hello MCA- Friends!

Last Year I searching for a new TFT- Monitor and by my search I see a TFT-
Monitor from EIZO which has VGA and BNC connectors with Sync- on- Green
support. It was for industrial use, big and not chaeap!
At the Moment I use for RS/6000 Machines two Iiyama Monitors 17" + 19" and
of Course a IBM 6091 19i.

Hi!

Uh, Rick, what LCD has BNC inputs?

CRT. Repeat after me...C-R-T. A good working CRT capable of sync-on-green
operation shouldn't be too hard to find. Secondhand monitors in good
working
order generally go cheap. I had a NEC MultiSync 17 *given* to me, as well
as
the 5-BNC Belkin cable. Seven years later I still have it, and it still
works great. It can accept 15-pin VGA, BNC (with sync-on-green IIRC) and
Macintosh 15 pin video.

I've never seen any flat panel display with BNC inputs.

Why can't I go from a 5 BNC to a VGA plug? Roll your own, as it were...

The big issue seems to be the delivery of sync information. VGA monitors
expect distinct sync information for horizontal and vertical
synchronization. They have a set of pins for each. That said, you may well
find a VGA monitor that is perfectly happy to violate the standards and
receive sync-on-green via its 15-pin connector. You can certainly try to
build such an adapter...but finding a monitor that will accept it may be
hit
or miss. The good news is that you (probably) can't blow anything up by
testing this.

It may be possible to build a device which would separate or regenerate
the
sync signals out to distinct horizontal/vertical sync, but that's likely
to
get expensive very quickly.
