Then they need to send you a new one and get that one back to figure out what they did wrong!
Yeah, I'd love to hear some more details on attaching the HP material to a DIY screen. Did you glue velcro to the back of the screen and to the front of the frame? Or, did you glue the velcro to the perimeter on the front of the screen and velcro to the back of the frame? Did you use anything to stretch the material? What materials did you use for the DIY frame? Thanks, I'm about to jump on board with the cheap Model B and hopefully create my own fixed frame.
Well I replaced my 2.8 133" HP with a 2.4 133" HP. My projector is ceiling mounted so it is not ideal. I have had the 2.8 for seven years so I was familiar with the picture.
I was scared that there would be a noticeable loss of brightness. I am happy to report that the 2.4 seems to handle my setup really well and looks amazing with no real noticeable drop in brightness . In fact the picture seems more uniform with ambient light.
It also gives a sightly different picture which I think gives better color. Over all I love it and feel no regret.
