Newegg is a one stop shop for all of my computer desktop needs.  From my CPU's down to the last few cables, I have purchased nearly 100% of evrything I have needed from Newegg for the three computers listed above.  Go to Newegg and build your "Dream Machine" computer!


POTENTIAL SHORT THROW PROJECTORS AS OF 12-28-11   (I went with the Mitsubishi EW230U-ST)




MITS EW230U-ST 3' 7” 1280X800 16:10 2500 2,000:1 2.7" $650


Comparable ST projector at the time:

BENQ MP780ST 3' 7” 1280X800 16:10 2500 3,000:1 2.8” $1045

NOTE: When using a 12' diameter curved screen, we must use 16:10 Aspect Ratio. All projectors must be set on the same plane and NO key stoning can be applied.

NOTE: 16:10 DST = 85” X 53” per projector (IMAGE PROJECTION FROM LENS TO SCREEN)

NOTE: C OFFSET (Ceiling off set) = the distance from the top of the projected image to the center of the projector's lens.
NOTE: At this distance on a 12' diameter curved screen:
800 X 600 = 106 pixels per square inch 480,000 total pixels
1024 X 768 = 144 pixels per square inch 786,432 total pixels


      800 X 600          106 PSI                        477,530

     1024 X 768         144 PSI                        786,432    

     1280 X 800         227 PSI                       1,024,000

     1920 X 1080       511 PSI                       2,302,055

1280 X 800 = 227 pixels per square inch 1,024,000 total pixels (I am using this type)
Fun fact: There are 3,072,000 pixels when using a three projector system in 1280 X 800 Native
Resolution on a 12' diameter screen system.
