Thanks Azzy, but I think I have it covered.
This morning, she refused to come up at all. Every time I cycled the power button (on the monitor) I'd get half a second of the full screen (with all the icons and my desktop and such) and it'd wink back off. It's almost certainly the backlight, but I absolutely do NOT have time to screw with it right now.
I had to light out before I'd even had breakfast and picked up a new monitor from one of the local big-box stores. Which proved to be more of a problem than I'd expected- Walmart only had one monitor. Not "left in stock", one spare monitor, period. They don't bother carrying much anymore, which I suppose makes sense since they don't carry any desktops either. All they have is laptops and tablets.
The one they had was some way
off-brand 22" piece of crap. The other box store carried exactly twice as many- a 27" HP, and a 24" widescreen format Acer. But, they were out of stock on the HP (and the demo model was ghosting) so I was pretty much stuck with the Acer.
But it's not bad for $130, and got me back up and running with a minimum of hassle. Which was important because today was loaded
. I had the PC back up and running by 9:30, had my postage printed and was out the door by a quarter-'til. I didn't get back in from the shop (except for a quick lunch break) 'til well after 11 PM.
The Acer is nice and clear, but I'm not thrilled with the "widescreen" format- it's actually about 2" shorter than my 24" Dell.
I'll set the Dell aside and maybe try and fix it, or just throw it on Craigslist for somebody else to fix. I have a LOT on my plate right now. And at some point later this summer, I'll probably grab that pair of Dell 27's and finally get this desk set up right.
