Looking for a 120-125" screen to pair with my JVC NX7. I have 100% control of the lighting in a dedicated HT room. However, I do occasionally want to watch with some lights on so need to factor that in. All seating is directly in front of my screen but would also like about 30 degrees off axis viewing if my kids sit in a bean bag chair off center. Looking at a Dark Energy Pulsar or SI 1.2 Slate. What else should I be considering to meet my criteria? I do not need an AT screen. Looking for the best possible picture, brightness, black levels, etc.
