As you can see, there's ample opportunity for lots
of work.
When you're done, however, you still have a fixed-frequency monitor,
though a nice one, and need another monitor and an A/B switch box
to switch the signal to the multisync monitor for text and other uses.
Like I said . . . it's a pain in the gluteus maximus.
A pretty decent 20" Sylvania multisync monitor with
really bright and sharp, as well as linear, image costs $279
at Costco.
Thanks for that, but TBH it's not worth the effort. I've got schematics for
an SVGA-5 BNC box that I might build sometime, but before I even do that
I've got to sort the monitor itself out.
