I have never been overly fond of projectors that require alignment of multiple panels due to pixel registration issues and the resulting fringing and softening of the image. I therefore tend to gravitate to single chip DLP projectors and currently use a THX professionally aligned (ISFTV, Kevin Miller) BenQ W10000 that meets REC709. While the ultimate black to peak white contrast ratio of most home DLP projectors cannot match that of many three panel devices, they do generally have a good ANSI contrast ratio which provides me with an excellent image. In low level scenes, the picture doesn’t provide the inky blacks of many three panel projectors, however, I still prefer the overall performance and sharpness of the DLP despite it occasionally showing the rainbow effect.
I am not rushing into purchasing any native 4K projector due to their limitations in meeting the various 4K HDR, WCG, possible Dolby Vision support and their pricing. However, as of now I am most likely to purchase a JVC DILA as it is the only cost effective projector that has the potential to meet many of the 4K requirements; more about this topic later.
My screen is a tab tensioned, matt, unity gain Da-Lite, with dual masking for 2.35:1 and 16:9 – 106”Wx45”H (115” diagonal for 2.35:1). In order to fill the widescreen I use constant height and a Panamorph UH380 on an ATH2 motorized sled. This lens may ultimately have to be upgraded once a 4K projector is installed as even though it is set for its optimum distance to gain its maximum resolution and performance. I think that it may de-grade a 4K image.
