With the JVC's Cinema Image Profile and Low Color Temperature presets selected, its grayscale tracked within ±443 degrees kelvin of the 6,500-K standard from 30 to 100 IRE -a somewhat below-average level of performance. Adjustments to the red, green, and blue settings in the User color-temperature menu improved performance considerably, resulting in ±156-K grayscale tracking from 20 to 100 IRE. Color decoder tests showed 0% error for HDMI and only +5% red error on the component-video input. The projector's red and blue primary color points, meanwhile, measured close to the SMPTE HD specification. Green displayed a noticeable degree of oversaturation, however.
Overscan - the amount of picture area cut off at the edges of the screen - measured 0% for 1080i/p signals with the Mask option set to Off. The projector displayed 1080i/p and 720p test patterns with full resolution via the HDMI and component-video connections, although resolution test signals showed a slight rolloff at the highest frequencies. The projector was able to accept 1080p/24-fps signals via its HDMI inputs.
Screen uniformity was very good, with only a slight pinkish tint visible at the far right side of the screen on full-field gray test patterns. A degree of red color fringing could also be seen even after tweaking with the Pixel Adjust feature. Standard- and high-def Silicon Optix HQV test discs showed picture softening when noise reduction was applied, although no ringing artifacts were visible in motion sequences.
