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?
