The distance from the garage wall to the hot tub is 30 feet. The viewing size area on the garage is 16 feet (wide) I believe...I will need to check.
I am open to putting the components wherever is needed...just want to make sure I get the best video quality possible given my back yard setup.
Problems to overcome:
Optimal screen size to viewing distance is influenced by projector resolution, source, and personal preference. A very general ratio is 10-12" in diagonal for every foot in distance. 30' would be 300" to 360".
If width of the area where the screen would be is 16'/192", then the biggest screen that would fit (16:9 format) is 220.3" diagonal.
Projectors that can be placed at ~5' and are capable of such a big image must be UST, but I'm not familiar with models that can do more than 120".
Ambient light will hurt contrast and black level in particular, so control of ambient light so that it does not hit the screen directly is important.
Even with ambient light control, there are no Home Cinema projectors that can light up a 220" screen with I assume some ambient light. Again, this setup is plausible only during night time, with dusk being possible with a very bright unit.
Projectors that can be placed at a distance, light up a 220" screen, even in dusk, do exist, but they are venue projectors and don't exist in the sub 3K$ category (new at least).
If the screen diagonal could be lowered, to say 140-120", a relatively cheap projector could work, i.e. Epson HC3700 for 1080p and HC3800 for 4K.
UST's require the screen to be perfectly flat, and I'm not sure what the screen setup will be like.
Calculator for the HC3700:
Or this option: Epson Home Cinema 1440.
The HC1060 is not as bright, and has a lower throw ratio:
The calculators show where the projector would be in relation to the screen. The HC3xxx series has lens shift (at the bottom of the page on the calculator), the other two do not.
