But as you start going with higher budgets you might as well get that extra performance from a quality screen. I don't know what the price of an HD5 is but if it is anywhere near the HD4 you are not in the budget range of projectors. Is the HD5 shipping yet? Get some samples and check them out. See which you like, maybe the gain is more important to you with that screen size or maybe you prefer the picture quality of the 4k. But, don't skimp on a screen when you are spending that type of money. You'll be much happier in the long run if you know you got the screen that better suited your purpose. Give Chris a call he'll help you out.
Thanks Bob. The HD5 is deff not budget, but for the class it's in, it's an outright bargain! From what I would gather, one would need to spend damn close to six figures to improve on its performance...heck, I'vs been told by a few that I'd need to spend upwards of $75k with some of the other well known manufacturers to get the same performance. I am still going to fly out to see one in the next couple of weeks before I buy it, but so far the details I have gathered in my research look outstanding. 6k lumens, great contrast, veriscope, etc. I am still trying to figure out which model proejctiondesign it coincides with but am coming up cold. Hopefully I wil hear back from Jim soon with more details.
If the HD5 performs like they say, the 4k will be a no brainer, I think, as it should have enough claibrated lumens to get me over 20ftl, even on the .85 gain screen. I am a real knit-picker too, so based on the few I have heard that say they can see the texture in the XD from a decent distance, I'd say it's the right choice. The price on either screen is fantastic, so it's not really about that, but moreso the final assessment of the HD5 and it's true light output capabilities will be the deciding factor.
