Projector Advice
I need a decent projector, mostly for static slides (powerpoint kinds of stuff rather than video). It will be permanently moutned in a decently bright room though in an alcove where there is less light. We have used a 3000 lumens projector for about ten years but it seems dimmer than it used to be and the colors were never very clear. The throw distance is 20 feet with a 12 foot screen. Looking at something around 4000-4500 lumens and operating on a small budget of about $1000. Any recommendations on a good projector?
