I'm thinking back to basic testing of dumb terminals and conecting pin 2 and
3 together would echo keyboard to screen.

Google doesn't like the word exerciser.
Is it possible to connect 5V to a pin on the monitor lead to get a blue
screen or something even if not synced to save powering up a pc just to see
if you get any sort of display on the screen?

Without something to generate sync you won't get anything useful on the
screen.

Well, newer monitors might display: "No Sync".

However, I agree that in genenral, unless you want to invest in a monitor
test partern generator, there is no trivial way to guarantee that any
monitor will display something useful without a proper driving source.

It's not what you could call "cheap", but the tiny monitor tester
which is sold by Anatek Corp works very well and eliminates the need
to connect a monitor to a PC to see how it's performing. It's at

Bob,
I have one of these also and am pleased with it. You can even take it with
you to a tag sale to see if a monitor works before buying it.

Buy a monitor? I've had over 50 good monitors donated in the last
couple months.

I bet Don Lancaster could do it in one chip.
With half its pins broken off.

The monitor tester does it with one chip, as I recall. C'mon, the
self-proclaimed "Guru" is extremely talented and an excellent
technical writer (I learned microprocessors from his book), but not
perfect.
