13W3 to HDMI/DisplayPort

I've had good success using various Extron adapters.

I'm currently using a RGB112xi to convert <anything analog> => VGA.

So far the adapter works as advertised with anything I managed to connect
it to (various HP/DEC/Sun/SGI/RS6000, including mono and SoG) to a cheap
Dell monitor that definitely doesn't understand sync on green. The adapter
fully regenerates all signals including separate H/V sync.

>From there I would assume any cheap VGA => HDMI adapter should work (but I
never had the urge, because HDMI monitors also tend to be wide format which
doesn't work very well for classic computing)

I also have other Extron converters, but the RGB112xi is best for 1990s
workstations. The only thing I wish it had was a way to choose the color
when the input signal is monochrome.
