You know, this might just be one of the easiest reviews I've ever had to do. Why? Because JVC's DLA-HD750 is designed to be even better than the already extraordinarily good HD350 we tested a few weeks ago. So if it lives up to its billing, really the only area that might require any sort of debate is whether it really justifies its £5,295 cost - a hike of more than £2,000 over the HD350.
Regular readers will be familiar by now with the groundbreaking Wire Grid optical technology that helps JVC achieve class-leading black levels from its proprietary D-ILA projection system, so I won't go into it again here. (If you're not a regular reader, I refer you to earlier reviews of the DLA-HD1, DLA-HD100 and HD350).
Instead, the best place to start would seem to be by looking at how the HD750 supposedly improves on the HD350.
The single most significant development is that the HD750's claimed contrast ratio is 50,000:1 versus the HD350's 30,000:1 - a potentially awe-inspiring difference considering that the HD350's black level performance was more or less immaculate.
Don't forget, after all, that the contrast ratio numbers described by JVC are, unusually, native figures, meaning that they're not dependent on the dynamic contrast systems employed by lesser projectors to produce a convincing black level. In other words, the JVC projectors can deliver their deepest blacks without having to reduce the output of their lamps and thus limit the brightness of any light elements a predominantly dark scene might contain.
Another potentially huge enhancement offered by the HD750 is a genuine colour management system. This allows you to tweak the hue, saturation, and brightness of the six main colour components of the image, and provides three memory slots for storing preferred colour arrangements for a variety of source types or, more likely, room light conditions.
While this is a decent enough system - and one that's long overdue on JVC projectors - it's perhaps still not quite as sophisticated as I would ideally have liked. It's certainly not in the same ballpark as the astonishingly flexible and accurate system supported by SIM2's C3X 1080, for instance - though that projector now costs £23,000! But more tellingly, I also felt like I had marginally more control over colour with both Panasonic's PT-AE3000 and Sony's recent VW80 - thanks in part to their more sophisticated user interfaces.
