I've owned a Samsung Syncmaster T240HD 24" LCD monitor for about four years now and I've just recently just discovered it has built in speakers. I did not know that. I've been using my Klipsch 2.1 speakers forever and I'm now wondering if I'd be able to use the audio out on my video card to plug into my LCD screen and get twice the sound. Probably not but I'm gonna try it anyway.

So, what things have you now only recently discovered about things you've owned for a long time?
