Q. I'm in the market for a new computer monitor. It will be a flat-panel model, of course. I've read your tips on selecting a computer monitor. However, there is one thing that confuses me. What's the difference between LED and LCD? The LED monitors are much, much more expensive than LCDs. I've also heard mention of OLED displays. What are those?
