Black levels on the HW40 will be slightly better than the HT5550, but the Benq achieves this with an active iris. The HW40 has around 5000:1 native contrast, no iris. Native is better.
Although the walls are not treated, that setup will be suitable for a projector with ok black level.
Those Optoma 50/51 mentioned don't have good black level, compared to what the Sony can do.
If you want to go with a projector with mediocre blacks, go with the HT3550. It at least has an iris.
The two UST's are ok black level wise.
The Optoma UD50/51A are considerably brighter than the HT3550, which helps with the perceived black levels and, of course, with 3D. Dynamic Black works as an Iris and also considerably extends bulb life. My opinion is to consider the HT3550 as a top choice for higher gain screen sizes of ~100in or less.
From Erbele's ( reviews: https://hometheaterhifi.com/reviews/...ay/projectors/
In HDR mode with the lamp on Bright mode and Dynamic Black on, I measured 224 nits peak, .1308 nits black, and 1711.7:1 contrast.
224 nits on a 92in screen = ~1630 lumens which is why I can use my UHD50 on a 145in low gain grey screen.
In HDR mode, with the lamp on Normal and the Dynamic Iris on High, peak white was 90.6794 nits, black was .0434 nits, and contrast was 2090.4:1.
in a less than optimal room, a brighter projector will give a better perception of black because the eye judges blacks relative to the the brighter portions of the image. Actual, on screen, contrast is always just a fraction of contrast measured directly from the projector. High output is especially important for HDR content.
