Which is more important for a better picture, brightness (Lumens) or contrast? The Toshiba MT7 has 1000L but only 400:1 contrast vs. Epson TW-100 700L and 600:1 contrast. Which one will have a better picture in a light controlled room using a 120" screen?

If the room is light-controlled, usually contrast is more important. But a 120" screen requires a lot of light no matter how you cut it...so both

2nd thought..one cannot and should not trust manufacturers clamied contrast ratio. Wild speculation at best with the only way to tell what the true contrast is, is to see them yourself.
