Front runners: Optoma hd131xe VS Mitsubishi HC7900DW
Is there anything better for $1k than the Mitsubishi HC7900DW?
It's going to go in a basement so light is controlled. About 100" screen size.
I can leave or take it. so not really.
Are you planning on mounting this to the ceiling and running cables?
At any rate the Optoma 25e is going to be too bright IMHO for a 100" screen unless you have tons of ambient light in the room.
The Mitsubishi HC7900 has vertical lens shift. What this means is that it will be much easier for placement options and easier to mount. For a 100" screen it should have plenty of lumens and a 15' throw works well with this projector on a 100" screen:
The BenQ1070 has more limited lens shift in that is has vertical lens shift only. That means you will need to align the projector to the center of the screen perfectly to avoid using keystone:
The Optoma 131Xe is going to be brighter and make work the best if you plan on watching if there is light in the room at all. That said, it has no lens shift. That means you need to have more flexibility in terms of where you place the screen and the projector to align them properly:
I own the Optoma and love it, and it is the cheapest of the projectors listed. Being honest, I would probably go with the HC7900DW only due to the smaller screen size (100" diagonal) and the lens shift option which gives you more placement flexibility. On the downside Mitsubishi is leaving the projector market. They will still honor their warranty, and it also explains the deal on this projector
My Bargain Basement Theater
How much lens shift is available on this Mitsu projector? It seems to be pretty low, or am I reading the throw calculator on the website wrong? I will have 103" high ceilings (8' 7"). Assuming 5" for a low profile mount, the projector top would be 98" (or a bit over 8' high). The calculator tells me that I need to mount my screen (120") -- 15" below the top of the projector, even with lens shift activated. Is that right? This would be my first projector -- so please tell me if I am screwing something up. Placement would be in a dedicated theater with full light control (no windows).
I was trying to figure out the same thing because I plan to have the screen come down over a desk that's 30" tall and want to make a 106" screen that''s 52" tall with 93" ceiling leaving me with 11"of play. According to the manual, it seems like for a 100" screen by default would be 16" below the lens, but at the "highest" lens shift it's 7" less which makes 9". I was planning on screwing a 1/2" thick piece of wood between the joists and have the projector screwed onto the piece of wood to have it as close to the ceiling as possible as well as screwed into joists.
I'm still deciding what model to get as my 7 year old Sharp DT-510 is dying (I've brought the color wheel back to life 3 times so far by lubricating it and/or soaking the color wheel and motor in 70% alcohol). The HC7900DW is very tempting, both my previous projectors I had got a similar deal where a previously much more expensive projector when on sale for a faction of the original price, I prefer this to getting a low end model of similar price.
My current projector makes a 78" image and is 1000 lumens and it's more than bright enough to be viewable with the lights on, would the HC7900DW making a 106" screen be about the same brightness as my 1000 lumen projector with a 78" screen?
Are there any cons to the HC7900DW I should know about? Is the dynamic iris something that ends up failing like color wheels after several years?
