I blogged last week about my shiny new 20" Dell widescreen, and alas, it needs to be replaced.
I've had a total of three other LCD's, plus laptops, but I've never had one burn-in or ghost. This one is doing it big time. On a black or gray background, you can see my desktop background, my chat client, icons and the task bar. Worse, you can see a window that was only there short-term.
There's also a moving "wave" down the one side of it that's annoying. Between those two problems, I speculate that there's some kind of power problem in the monitor that's pushing too much into it or something. I mean, I've seen the Apple part in stores (uses the same LCD), but this one does seem almost unnaturally bright. Oh well, we'll see what the replacement does. It should be here in two to three days.
