The JVC DLA-RS49/RS4910/X500R: Why They Won
We had the RS4910 version here. From a performance standpoint the three projectors are identical. The RS4910 goes though one distribution channel through the AVID distributor, the RS49 another channel, and the X500R still another. The RS4910 costs more than the others, but for that you are getting a longer warranty, not better performance.
In reviewing the RS4910 I was really surprised. I’m used to the top of the line JVC’s such as the X700R and X900R (essentially the same, but for quality control of the components, and a hefty price difference), being the king of black level performance, with the lower end models a definite step down. This year though, JVC upgraded the LCoS panels in their new models and added a dynamic iris! Those two improvements allow the RS4910 to produce outstanding black level performance, perhaps exceeding last year’s top of the line projector (at $11,999). In fairness those top of the lines last year did not have a dynamic iris, they did it natively.
Still, JVC now has a pretty smooth iris action and the resulting black level performance of the RS4910 is so good that I have to wonder if their more expensive projectors can be worth the extra since in theory, it’s better black levels that you are paying thousands of dollars more for.
