Here's a closeup of the building above.
Above is the Acer, below, the BenQ
While you are observing the two images above, also look at the sharpness. You can see that the BenQ is definitely the sharper of the two.
Ok, back to our black levels and shadow detail.
The satellite photo looks pretty good, but blacks are not as dark, "inky black", as more expensive projectors. Most of the dim stars are visible.
This overexposed (above) image of Clint Eastwood in Space Cowboys, reveals a respectable amount of shadow information in the wall on the right half of the image, but the blacks don't get black enough to bring out all the information.
Next is an image from Lord of the Rings. This image below is badly overexposed so you can see the details that the projector captures in the shed on the right, along the ground and the structure on the left. This image is available in most reviews done in the last couple of years.
Our last image is from Space Cowboys, and is an overexposed image of the re-entry scene. Click on the left thumbnail image. Look for subtle detail in the right side of the earth. The image to the right will be from the Panasonic PT-AX200U, a projector I am reviewing right now. It will be plugged in in a few days, and I'll update this content.
