Okay, so the old monitor suddenly faded out and went dark.
It was probably long past time, as it was pretty ancient.
I had a spare monitor here, and hooked it up.
It's an Optiquest Q51.
It's smaller than the preceding monitor.
The color/contrast is way too dark. I don't mind the miniature print--after all, I have good eyes--but I do mind that everything's far too dark.
There's four buttons on the lower left-hand side of the monitor.
I punch one, and get a little rectangle in the middle of the screen, blue and green, CONTRAST.
But after getting that, it doesn't tell what one does next.
I went to the web-site of Optiquest Q51, the "service manual," and damn it, it has no such instructions.
I'm headed to the big city soon, and I imagine I'll just go ahead and pick up a couple of new used monitors at the thrift store, to see if they work any better. But as this one seems to work, I'd still like to keep it as a spare.....provided I can figure out how to lighten it up.
