The JVC's Cinema picture preset with Low color temperature selected initially delivered the most accurate color reproduction. Grayscale tracking was ±219 degrees K of the 6,500 K standard from 20 to 100 IRE - very good performance. Adjustments made to the red, green, and blue controls in the Memory Color Temperature and Image Offset submenus improved grayscale tracking to an exceptional ±89 degrees K from 20 to 100 IRE. Color decoder tests revealed zero red and green error for both the HDMI and component-video inputs. As compared to the SMPTE HD specification for digital TV colors, the set's red, green, and blue primary color points showed relatively high levels of oversaturation - a situation that could be remedied to a degree by using the separate red, green, and blue adjustments in the Custom gamma setup menu.

The JVC's 15.0 ftL post-calibration brightness was about average for a projector in its price range. In my room, I measured native contrast ratio at 14,980: 1 - the highest number I've seen since I first started doing contrast ratio measurements on front projectors. Overscan measured 0% for 1080i/p-format high-definition signals with the Overscan Off mode selected. The JVC displayed 1080i/p and 720p test patterns with full resolution on both the HDMI and component-video connections. And picture uniformity was excellent: black and white fields showed no sign of uneven brightness, while gray field patterns were free of color tinting.

As with other displays I've tested that use a Gennum video processor, the JVC passed all the tests contained on the Silicon Optix HQV high-def test disc with the exception of Film Resolution. I saw no ill effects from this on any of the high-def reference discs that I use for testing, however, and the projector's upconversion of DVDs and standard-definition TV programs was crisp and artifact-free. The projector's video noise reduction processing worked well at the lower range of its settings, but it visibly reduced picture detail on both standard- and high-def programs when boosted beyond the mid-point.
