That said, it's not like 4-5 years ago, when seeing the darkest shadow details was easier, because those older projectors had (compared to projectors like this Sony), inferior blacks, and everything was lighter. Just remember, rarely is the important stuff in the darkest details, rather, you mostly want to avoid having large "flat" areas where all detail is lost. That's something, generally, I only really encounter today, on entry level home projectors, but, that tendency years ago, is what put "black level performance" in the forefront of enthusiasts attention. (If the projector is just flattening the near blacks, and all that detail is gone, then you want that area to be "black" not medium dark gray, making black level performance important.) But, let's move on to the images.
The night train image does a great job for checking out shadow detail. This is a very dark scene overall. Look to the shrubs on the right, especially behind the tracks, and also look for shadow detail in the wood behind them. Click, as usual, for a much larger image.
