Yamakasi Sparta, and Crossover 30Q5 are CCFL lit, this one is LED. Worth noting.
To compare fairly, you need to look at the Yamakasi Leonidas. Same-ish price.
All 30" IPS monitors made to date have been LCD CCFL until just recently as Dell announced their new U3014 LED IPS display (which hasn't released in the U.S. yet). All the korean monitors are LCD despite some claiming they're LED. I highly doubt Monoprice is using the A- Dell U3014 binned panels.
