I prefer Aperture Priority for my screen shots here as well ! To get the field of view and depth of view for a specific aperture and focal length or figure out the focal length you will need to cover a screen of x size from X feet distance go here
The suggestion to stand directly under the projector lens is a good tip and is locating the camera lens as close possible to the center of the screen vertically.
I am sorry to see some (I did not take a physical count) of us are experiencing a banding problem. I scratched my head when I saw the work around suggesting unplugging the projector from the wall because my Pro8100 has not been turned off since I got it, and I have not seen any sign of this banding to date; but never say never. I am not knocking the work unplug around because this worked for me on lockups and various other issues.
There has not been a single handshake problem between the Pro8100 and my input sources regardless of whether the projector is started first or last which means Viewsonic did a good job on the HDCP handshake. Most of my HDCP displays want to be turned on FIRST and set to the right input to be 100 percent reliable.
Quick Update on my Pro8100:
Seller: Tiger Direct bought with Bing Rebate from Microsoft
Shipping Time: 5 days
Unit Manufacture Date: January 2008
Firmware: Latest version 2.5/2,51 depends on the remote. Interestingly the firmware was installed using M$'s Vista Home Operating system on a Lenovo Laptop. I cannot remember for sure but may have seen a warning about the install perhaps not installing correctly. Nevertheless, the firmware update ran flawlessly. btw M$ Vista is very quick to put that message out if the install differs even slightly from their benchmark; I run a number of programs that give this message from time to time so always run the program to check it and have usually found the install is fine. I have seen the message so many times I am oblivious to it now.
Installed: August 14, 2009 without checking the UPS receipt
Power: Unit plugged into an APC 1500 Watt Battery Backup - The unit has never been unplugged and the power has not gone out in the past month.
hdmi 1 direct from HTPC using Intel Q6600 with Nvidia 3870 and

Component 1 from Sony S7700 DVD Player
Component 2 from Xbox 360
Composite from Denon Receiver to see a screen for tweaking the sound system.
Banding: No Banding Problem with 81 Hours usage in first month.
Dust Spots: None yet; but will be cleaning the filter tomorrow per bouda78's suggestion above because I am so paranoid about dust i buy extra camera bodies to avoid changing lenses.
Auto Iris: Working Fine
Still extremely happy with Pro8100 (in fact in love with it after really taking time to calibrate it right) and think the unit is an incredible bang for the buck for reasons I have already stated much early on in this thread. BTW I and many others in this and other forums have spent multiples of this price for display units, projectors and display panels with equal if not more issues than we have seen so far on the Pro8100.
