Projector Reviews

Al,you have finally reviewed a projector that I own. I too experience the pumping of the dynamic iris. This is my first dynamic iris projector and it is very annoying for the picture to flicker. Is this normal for a dynamic iris projector to do? Also can you provide the post calibration menu settings. Thanks.

I was wondering if there was a mistake in the contrast ratio calculation. With the indicated ratio of 1370:1, the black would need to measure at 0.02 ft-l instead of 0.002 ft-l. I wouldn't have noticed but I wanted to see how the contrast ratio compares to the Sony VPL-HW45ES (which I own) and its review indicates a slightly worse black level (0.004 ft-l) but a significantly better contrast ratio (5650:1).

The price of the two are reasonably close, so was wondering which would be considered to be the better bang for buck purchase at this point. I guess I'm thinking that the BenQ has 4K resolution and HDR capability but was curious if the HDR's impact is hampered by the low contrast ratio. The 45ES is a pretty old model at this point, but I still thoroughly enjoy it. I've been watching for the replacement model more for curiosity's sake than anything else and haven't seen anything to date indicating that a replacement model is expected soon.

Al, I was wondering why with LED and laser light engines supposedly becoming more evolved and affordable why is a conventional lamp used here? I'm guessing it may be the cost/performance ratio must be more compelling? If so what's keeping the more modern light engines from really taking hold?
