What is the difference between a telephoto projector and an ultra-short throw projector?

[Joseph Brown]

Hi everyone, recently I was trying to set up a home theater. But I don't know much about this aspect. I don't know what kind of budget should be used to set it up so that it can have a very good effect. And I have read a lot of related reviews for these two projectors. If I compare two projectors at the same price, which one will be more cost-effective?

Honestly I'd push back on the idea that UST is the better value at the same price — the image quality per dollar still favors a regular telephoto, you're mostly paying for the short throw. Curious what you actually went with.
