Do you have more specific recommendations for screens? I can 100% light control my room, and am looking at 100 inches. I really need something on a stand, as I cannot drill into my apartment walls.

If you're at all handy, you can just build a frame out of 2x4's and mount the screen to that.

20,000:1 is bad?

That contrast ratio is measured "Full On / Full Off", which is essentially the same as "dynamic contrast" (In other words, it's meaningless).

Is there a way to connect a projector to surround sound without a receiver? Does a projector with optical audio out even exist?

I'm setting up a small home theater for my dad and I'd be bummed out if I need an entire new device to send video to the projector and audio to the system.

What kind of audio inputs does his existing receiver/surround system have?

LG did it first.

Probably a tenth of the price, too.

It will probably be bright out for most uses. CFL/NFL games, MLB, Hockey playoffs etc. all usually running around 7-10ish PM

I'm trying to learn about Lumens and one site tells me I need at least 3000 for daylight.

Keep going.

A few definitions to get us started: Lumens is a measure of total light output. Lux (or luminous flux) is a measure of the average amount of light over a given area. So a projector (or any source of light) gives out light measured in lumens and casts light on an object measured in lux. It's this lux rating you care about. Basically, the ambient lux is going to be your "black" level. You can't go darker than that. So you need a MUCH brighter light creating your bright spots to give you a good contrast ratio compared to ambient.

A 100" screen is about 360 sqft. 5000 lumens across 360 sqft is ~150 lux.

An overcast day is ~1000 lux and a sunny day can be 10,000 lux or more (in the shade). Direct sunlight is something stupid like 50,000-100,000 lux.

TL;DR: What you want to do is impractical at best.

Probably dynamic contrast. So yeah, made up.

Probably because projectors are designed to be used in the dark and tables aren't.
