Author Topic: REAL D XL David Stone Film Handler Posts: 75 From: Hornsby, Sydney, Australia Registered: Jun 2008 posted 02-04-2011 02:50 AM                     Hi Everyone. I currently have a Zscreen set up but would like more light. Is there any technical reason why RealD requests a 600x600mm port. I now project a 140mm tall image on the port glass on scope and the port glass is 350mm tall. Would it be technically possible to project the twin XL image through my existing port. Kind Regards, David  |  IP: Logged Jorgen Larsen Film Handler Posts: 18 From: Denmark Registered: Jun 2009 posted 02-04-2011 04:29 AM                     Hi I can send you the RealD port window analysis. Here you can calculate the window size. Send a Email adress if you want the sheet.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

The upper image will be larger AND it will be spaced off of the lower image at the point it hits the glass...hence the need for the 3X size. And all of this presumes you have the ability to raise/lower your projector to get it to shoehorn through the opening. Real-D went with 600x600 (though it is really the height that grows substantially) to cover most cases. -Steve  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 04-08-2012 03:48 PM                 It has been 429 days since the last post.  |  IP: Logged Tom Wienholt Master Film Handler Posts: 371 From: Towson, MD, USA Registered: Dec 2002 posted 04-08-2012 03:48 PM                     Jorgen, Where can I find the RealD projection port analysis sheet?  |  IP: Logged
