Detecting bad pixels on your new LCD monitor

I've just got a new 17" LCD monitor, my first ever,(thanks KFM :p) and though common sense tells me that if it had dead pixels (as is not uncommon with LCD screens) I'd notice them eventually, curiosity got the best of my proverbial cat and I wanted to know Right Now. Ergo, the Dead Pixels Test. The test is really just a patterned background image that makes dead pixels stick out like a sore thumb, but it's handy and does what it claims to. The verdict? Miraculously, my pixels are 100% intact.
