Question Using a Projector for Your Smart Trainer Display

I wish I had never seen this video...


While I have a decent sized TV that I use for Zwift, my brain really loves the idea of using a project to make the indoor riding experience a bit more realistic. I would think that riding Rouvy while using a projector would be the cat's pajamas.

For those of you that have already made this dream a reality, please share your setup! Pics, specs, which projector you're using, etc.

As I research this topic, I'll update this post as I answer questions I have (which will probably be questions you'll have, too.)

Question: Ideally, I'd like a setup where my bike and trainer is relatively close to the screen w/o seeing my own shadow. I'm assuming that would mean mounting the projector over my head and having to use the projectors "keystone" settings to adjust the screen dimensions(?)
Answer: A "short throw projector" allows for mounting the projector relatively close to the wall it's being projected on.



Question: Do you need a dark room to use a projector? Most projector images look "washed-out" to me.
Answer: Several factors affect the projected image: The lumen output of the project and the screen being two major factors. A higher lumen output project will be able to display a better image in a room that has ambient light, like from a window. An ALR (Ambient Light Rejecting) screen can also help reduce glare from ambient light.

Question: Is a projected screen image big enough to make it worth all the cost? Can't I just use an inexpensive TV?
Answer: A non-"smart TV" can be purchased for a really low price in relatively large sizes, but no where near as large as a projector can project. For example, a 100" diagonal projection size is quite common. Take a tape-measure and see how big 100" is... it's really big!
