We have two 540's at work and I have been impressed by the color compared to our older Infocus 425z. The only thing is that I can notice the pixels a great deal more with the 540 even though it has 1024 pixels compared to the 800 pixel Infocus. Since I can not get a LP340 to do comparisons, has anyone seen both? I have heard the 340/350 have far better color than the old 425z. I also wonder about the brightness difference of 1300 vs 1000 lumens.
