I have purchase , this projector to replace my 6 year old NEC projector . I like that it have a hdmus input , 2500 luman , and think it would have a clean sharp picture . but I fail to notice that it be only 800 x 600 resolution . with my picture about 6 foot wide . the picture look blocky -lrb- if that be a word -rrb- . I could actually count the pixel on the screen . I have return this Vivitek projector and purchase another NEC NP216 projector with a 1024 x 768 resolution . the 1024 x 768 resolution make a huge difference in clarity . I will never purchase anything less than 1024 x 768 . I be sure a Vivatek projector with 1024 x 768 or higher would have a better picture .
