JVC DLA-RS1 and Sharp XV-Z20000 Home Theater Projectors: A Comparison Review – Overview
JVC RS1 and Sharp XV-Z20000 Remote Controls
I wrote in the RS1 review that it has an excellent remote, and found the Sharp also to be excellent. Between the two, for working the menu, arrow keys and enter functions, I’d have to give the XV-Z20000 a slight edge. (I favor the menu/arrows/enter to be near the top, like on the Sharp, while they are near the bottom of the RS1’s remote. On the other hand, the RS1 has more buttons offering direct access to adjustments, not only a separate button for each picture mode (Standard, Natural, Dynamic), while the Sharp has a single button for picture mode bringing up a menu. The JVC has a button for each saved memory, plus buttons for color saturation (up and down), contrast, brightness, gamma, color temperature, and so on. The XV-Z20000, does have some good buttons too, including iris, contrast and brightness, but in all cases, it still brings up menus, rather than direct control.
So from a feel standpoint, the Sharp remote has a slight edge, and from a functionality standpoint the JVC wins. Still, both are really good remotes, and both have no range problems in larger rooms. Lastly, both have backlights that are sufficiently bright.
Sharp XV-Z20000 and JVC RS1 SDE and Rainbow Effect Issues
Neither projector has an issue with screendoor effect. At normal seating distances, pixels just are not visible with either projector. The JVC with its D-ILA chips (LCOS) have much less visible pixels than the DLP chip in the Sharp if you get really close to the screen, but both are below visibility at normal seating, so a difference is a non-issue.
Rainbow Effect. A small percentage of the population is sensitive to what is known as the rainbow effect, caused by a single chip DLP projector’s spinning color filter wheel. There are no published numbers as to how many are affected, but it’s probably in the 1 to 5 percent range, and the amount of sensitivity varies. Myself, I occasionally spot rainbows around fast moving white or near white objects moving quickly across a pretty dark background, when viewing DLP projectors with 5X color wheels (the fastest currently used). I’ve lived with three previous single chip DLP projectors, but notice the effect only very infrequently, and more so if I’m moving my head, or am especially tired, late at night.
If it turns out you can spot rainbows on the Sharp, that’s a reason to favor the JVC as your choice. Having watched the Sharp and JVC back and forth for the last three weeks, the rarely visible rainbows are not enough for me to have picked the JVC for its lack of them, but, at the same time, the occasional spotting of them with the Sharp, makes me happy not to have to deal with them with my own home theater projector. Your projector is likely to be a family purchase, make sure none of your immediate family finds the rainbow effect to be significantly visible.
JVC RS1 and Sharp XV-Z20000: Light Leakage
The JVC definitely leaks more light out the lens than the Sharp, but the levels are so low, I don’t see it as an issue. The only time I notice it on my JVC is when I have first powered down my source and am looking at a fully “black” screen. Note, typically, projectors leak more light out their lenses, when lens shift is being used near its extreme. The Sharp XV-Z20000, by comparsion leaks very little light. Ultimately though this is another area where neither projector has a visible enough light leak, to be an issue.
