JVC DLA-HD750 D-ILA Projector:
The color gamut and color tracking were both quite good for out-of-box measurements in THX mode, but both needed work. There’s a bit of a dance that goes on between the color points and the color luminance values, and the results I preferred weren’t always what I expected. (See “Color Me Accurate?” sidebar.) Also, it’s a little disappointing that the THX mode locks users and calibrators out of the user-menu adjustments for gray scale and the Color-Management system. You can select one of the User modes and adjust the CMS, but then the THX mode will no longer be the standard for accuracy. My last issue with this PJ’s implementation of the JVC’s THX mode is a real how-did-they-miss-this-one head-slapper. JVC’s remote includes direct, single-button access to every picture mode, save one. You guessed it. You have to dig in and manually select THX mode in the user menus. A single button push to THX rightness would’ve been swell.
Setup and Tests
As noted, the DLA-HD750 features a 16-step adjustable iris. The default Lens Aperture setting is 0, which is wide open. A setting of –15 offers the least light output and ostensibly the highest contrast. On my 80-inch screen, the white-window output at 100-plus hours on the bulb ranged from just over 20 foot-lamberts at 0 and 13.22 at my preferred –12 setting. I measured very carefully and found that I could open the iris to –12 without sacrificing contrast, so that’s where I left it. The DLA-HD750 isn’t a light torch, but it will produce plenty of punch on a screen that’s quite a bit bigger than mine in a room with solid light control. It looked terrific on Kris Deering’s 120-inch-diagonal screen in his black hole of a room, for example. (My testing was performed in the Normal lamp mode, but it also has a High mode that was not tested here.) There’s just no substitute for deep blacks. The HQV Reon-VX video processor performed as I expected it to, which is to say excellent. Over HDMI, it did an outstanding job scaling standard-def signals to the PJ’s 1080p resolution, and it passed all of our 1080i high-def deinterlacing tests with flying colors, so virtually all incoming signals will look their best.
At the Movies
While I note that the DLA-HD750 didn’t focus quite as tight or eke out quite as much small object detail as the DLA-HD100 (or the very best single-chip DLPs I’ve seen), I do have to note that it always looked more three-dimensional when you took the whole image instead of focusing on its smallest parts (something that often escapes we reviewer types). The sensation of depth was a continual marvel. Chapter 6 of The Chronic: Prince Caspian had the spooky clarity and dimension that’s usually associated with material originated on HD video. The colors looked gorgeous. The pasty English complexions, bright red arrow feathers, blue water, and green foliage all looked superbly right and convincing. Caspian might have disappointed at the box office, but on Blu-ray, it’s some of the most sensational HD eye candy I’ve consumed. Next, I moved on to a different world, literally. Werner Herzog’s peculiar and fascinating documentary of life in Antarctica, Encounters at the End of the World, also revealed more of the JVC’s might. Spectacular HD footage abounds here, but I was particularly struck by the lively but natural colors of the fleshtones and the North Face gear that everyone is outfitted with. People wear that stuff all the time up here in the Pacific Northwest, so it’s another real-world reference that the DLA-HD750 is just aces with. This projector feels very organic and is never digital looking when the material is up to the task.

After calibration, color tracking across the range was exceptional, and the custom gamma curves tracked their targets to virtual perfection. I dialed up a 2.3 gamma curve and found the results to be seductively film-like. White- and black-field uniformity, which is a bugaboo of some three-chippers, was also excellent. I looked at ramps and some computer animation known to accentuate banding or false contouring, and these revealed performance that was at least as good as the DLA-HD100 if not a little better. However, as with previous D-ILA designs, horizontal camera panning at the right speed causes an artifact that’s similar to false contouring. It only occurs with certain program material and with some test material that shows response-time issues with LCD flat panels. Other projectors, including some DLPs we’ve tested, are entirely free of these artifacts. This is seldom visible, so it wasn’t a deal-breaker for me.
