I have never purchased a projector before but I am looking to purchase in the near future. I have question about the selction process and what is going to get the most bang for my buck. I will be using this projector for standard house hold use DVDs video games and TV. I was wondering first off what are lumens? Will a projector with more Lumens be more visible in birghter ligh conditions? What are some of the trusted brands? I would like to spend about 2,000 or round abouts? As far as resolution goes, what is a very clean resoultion for a 60" to 80" screen? As you can see these are all very basic quesitons. I would just like to be as educated as possible before spending the money on my system. Thank you very much for your input and time.
