The Optoma HD131Xe has no problem putting out over 1700 measured lumens, which is about four times the brightness on your screen, as a typical movie would have in your local neighborhood cineplex.
That means plenty of brightness to tackle modest ambient light, even in less than ideal rooms.
The nice thing about having a bright projector is that it can handle some amount of ambient light pretty well. It was a usual sunny day here on So. California.
I started shooting the sports and other HDTV, early afternoon the shutters over half way open for the hi-def sports viewing.
Since most of the modes on the Optoma HD131Xe are relatively similar in brightness, the key element here is that I did all the normal sports images with Brilliant Color set to 10.
Room conditions - exposure set to show the room
Note that with minimal Brilliant Color (1), the projector surrenders over half of it's total brightness.
Exposure matched to the projected image
The image above was taken with a good exposure for the room to give you an idea of the ambient light. For this second image, the ambient light is the same, but the exposure is several f-stops darker, to show what the screen looks like, when properly exposed, but it makes the room look very dark, much darker than the reality.
For the non-sports images, the shutters were about 3/4 closed allowing in only a fraction of the light into the room.
Back of the room shutters just about wide open + light from skylight in outer room
