right now i might be getting a 17 inch with say 5 scattered dead pixels, I notice them in games but im stting right there, how noticable will they be when I make my projector, lukaly there no clusters of them just a few here and there, and this is a sony vaio so idk if you can even take it about

If you notice them in games, then you'll notice them on the big screen.

You may be further away from them, but they'll be bigger. My own screen takes up more of my field of vision than my 19" CRT that I'm currently sitting in front of.

well i thought with the decrease in quality and contrast ration you get with the projection 1 pixel might be faded out a lot
