Out-of-the-box picture performance is relatively good on this JVC model. I selected the Cinema Image Profile, low color temperature setting and normal lamp mode to begin my evaluation, as they produced the most accurate picture available prior to any tweaking. Color decoding is accurate for HD and for SD sources, which I understand wasn’t the case with some of the earlier versions of the RS1. Black-level performance is also very good, with excellent shadow detail in dark material when black is set correctly. The RS1’s video processing is excellent, with 2:3 pull-down for film-based material and correct de-interlacing of 1080i HD material. This preserves all the vertical resolution in 1080i HD sources, which not all HDTVs and projectors can claim. Since we are on the topic of resolution, the RS1 delivers all of the resolution in a 1080p signal at the component video input, as well as the HDMI inputs. I have found on many 1080p-resolution projectors, both LCD and DLP, that a significant amount of resolution is lost at the component inputs.
While color decoding and grayscale tracking are both superb, overall color accuracy is adversely affected by the inaccuracy of the primary and secondary colors. Green is particularly offensive. It may be the most skewed to yellow of any green I have ever seen on a display device. Of course, JVC is not alone in this, as yellowish greens produce brighter pictures, and projector manufacturers have always been in a light output war. The good news is, this won’t show up with all program material. I noticed it mostly watching the YES-HD channel on my Time-Warner cable system with Yankee baseball in HD. I couldn’t help but notice that the grass on the field simply looked wrong.
The last chapter of Seabiscuit (Universal Studios Home Video) on HD DVD looked mostly excellent with the exception of the color of the grass, and the other primary and secondary colors that show up in the jockeys’ jerseys. Of course, I may be the only reviewer who cares this much about color fidelity. I can’t help it, though, as I always go back and compare these pictures on my reference Samsung SP-H710AE, which has nearly perfect primary and secondary color space. Blacks are deep, rich and clean on the JVC, with no visible false contouring or low-level noise, which means the perceived contrast ratio will be excellent if your room is dark and non-reflective. In recent years, manufacturers have added contrast ratio to the numbers war they wage against one another. The RS1 is rated at a difficult-to-believe 15000:1. You may be interested to know that the human eye can’t see more than about 1200:1, and so if you get a real-world contrast ratio of 500 or 600:1, that is simply amazing, even for the most expensive high light output video projectors. By way of comparison, a well-designed movie theater yields not much more than 200:1. Chapter 28 of the HD DVD version of Batman Begins (Warner Home Video) is a good scene to test black-level performance on a projector. In this scene where Batman races against the cops to save the girl’s life back at his cave, shadow detail was quite impressive.
Casino Royale (Columbia/TriStar Home Entertainment), an outstanding Blu-ray transfer, was incredibly sharp and detailed on my new reference Samsung BD-P1200 Blu-ray player. The chase scene in the beginning, a very bright and oddly-colored sequence, had all the snap and pop you could ask for, and overall looked exceptional. Chapter 3 from the incredibly kinetic Blu-ray transfer of Crank (Lionsgate Home Entertainment) also had mind-bogglingly good detail.
Picture quality was further enhanced when I routed all my video sources through the venerable DVDO VP50 video processor, which output 1080p to the JVC via the HDMI output. The biggest benefit of the VP50 addition came with SD material from my cable system, which appeared a bit cleaner through the VP50. Since the JVC holds its own as far as processing or scaling is concerned, the main benefit of adding a processor like the DVDO VP50 is the simplicity of routing all your A/V sources through it, and only having to run a single HDMI wire to the projector on the ceiling.
