I be finally able to get the projector work with my MacBook -lrb- run Lion -rrb- after the support team send I the latest driver for the usb link . this process be quite frustrating yet I must say the fix work the first time . overall ok for customer service . pro : - display be very bright - the ability to adjust color be important as well and intuitive . - menu be simple and intuitive . - once customer support be actually engage , it work well . con : - I have a great deal of difficulty with initial installation with my MAC - despite the claim of ` it work right out of the box ' it do not . os x Lion have be out for over a year - why be they ship with a old driver ? - video playback for YouTube and DV file from my hard drive be choppy . the frame rate support by the projector be far from ideal . I find it quite noticeable . when I look at the computer screen the playback remain clear and chop-free . not sure what the issue be here , but this be a definite detractor . I need to test with a dvd and see if this be true for that as well . I will update when that test be complete . Update on pay a dvd from my MacBook : the dvd screen be a mass of gray and white square - no picture of the movie at all . I email customer support for assistance . - customer support get right back to I - which be great , but the the advice be to use the VGA cable to fix the issue I have . this show a basic lack of understanding of my system . MacBook do not support VGA cable , so they advice be useless . - customer support once again reply a couple of day later and advise I to purchase a adapter for the VGA cable to ensure that dvd playback on the MacBook would function properly . once again , I find this a less than desirable solution . it be not like mac be ` strange ' - VGA be old technology , it be time to update people ! I be reduce my review to three-stars base on this experience . overall - for the price - a very solid projector for business application . I can not recommend it at this point for entertainment application as the video playback be simply not up to par .
