Summary: Personal Experience We set up 3 units in a bowling alley for our customer and both of us are extremely happy with the picture quality. Being that I am the one actually installing it, I was very happy with the versatility this machine offers as far as full lens shift and keystone, along with all the connections. These units are super bright and at a 180 inch screen was very clear.
Excerpt: I did not know that this projector did not have and auto zoom, focus, and lens shift. I was mounting this projector in a theater where the projector sits about 18 feet in the air. I had no way to get to it when it was raised up. It created many headaches without the controls.
Summary: Personal Experience We had high hope for this projector but the quality just isn't there. It's not very bright and the construction is cheap at best. I wouldn't this projector on anything bigger than an 8ft screen with front projection.
Summary: Problems We had a power surge and now our projector is shinning very bright. The menu is normal but when you send an image it is bright. Also we have it hooked up to another projector that by itself works fine but when receiving a signal from this one projector it shines very bright also.
Excerpt: Buenas tardes de nuevo. Ahora os escribo de este aparato proyector NEC PA550W. Es con el que trabajamos en la empresa para las conferencias y presentaciones. Es de gama alta, como todo lo de NEC poco conocida, y cuesta alrededor de los 1150 euros, solo apto para empresas. Su aspecto es el común de todos los proyectores y la marca es la más fiable y es fácil de usar. El proyector tiene una resolución WXGA (1280x800), que está más que bien.
