Los unicos proyectores que he visto en pantallón son el infocus 4805 (pixelación, colores apagados y contraste insuficiente) y el sony hs-50 (pobre luminosidad y contraste pero definición excelente sin pixelar).
Cambiando a una pantalla bastante menor todo mejoraba. Supongo que es un tema opinable. No me cabe duda sinembargo que se pueden conseguir unos resultados dignos.
Como ya sabreis este es un viejo tema que se plantea la prensa especializada en sus análisis. Referente al pana 700:
Therefore there is always an aesthetic trade-off decision to make. Of course you want a very large image—otherwise you wouldn't be considering a projector to begin with. But where is the ideal trade-off point on image size versus quality? This is a matter of personal taste, and there is no answer that is right for everyone. However, assuming a light controlled viewing space, in our opinion the AE700 hits it optimum trade-off point in the range of 100" to 120" diagonal. Going larger than 120" diagonal begins to cost you noticeably in contrast and image brightness, and going smaller than 100" nets you some nice incremental contrast and brightness, but at the penalty of reduced image size.
If you do not have a light controlled environment, you should opt for a smaller screen size. If you have low indirect ambient light as a matter of course in the viewing room, we would suggest limiting the screen size to no more than 100" diagonal.
Of course for those who have a smaller viewing room or simply prefer a smaller screen size for whatever reason, a 90" diagonal image might be just right. In this situation the AE700 will deliver a beautiful, brilliant image that can be viewed either in darkness, or low indirect ambient light. So if 90" diagonal is the practical image size for your room, go for it. Don't oversize the image just because you can.
