Optimal 16:9 screen size for panny ptax 200 at 14 foot?

[admin_exported]

Should i get a 120" screen for £100 or 135" (the zoom max at the 14 foot distance) for £215?

I have heard the visual quality in many projectors decreases over 120", is the price difference and size difference worth the extra money?

Thanks for any help

I'd go for the cheaper one, and not push the projector to its limits. That way you'll get more even illumination and a better picture.
