===== JVC DLA-X7 ===== {{:grupub:jvc.pdf|JVC manual}} Tested on 2/7/2011. We first tested the HDMI inputs, but things were a bit funky. Each color channel saturated at the top output, and the test for a 12 bit gamma table came up with garbage (i.e. no increase in luminance as we stepped the luminance in the gamma table in steps of 1/4096). Also the yellow value does not appear to be on the line connecting green and red. The luminance saturation was ok with the VGA input, although the output does not seem to reach quite the same maximum luminance. The temporal frequency of the monitor can be set to 85Hz, but the display tested with a photodiode does not seem to refresh that fast - in fact, if you flicker the screen there seems to be a high duty cycle in which the screen is bright for longer than expected. This is very clear at 60Hz and if you flicker at 30Hz it is almost but not completely gone (i.e. the display appears bright for longer than 33.3 and dark for less than 33.3 ms. The transitions are very fast though. ==== HDMI calibration 1 ==== We tested with 1024x768 resolution at 60HZ bitDepth=32.

Matlab calibration is {{:grupub:0003_JVCTEST_110208.mat|here}}. Note that the output does not saturate at high values. Spectrum of RGB KW CMY

===== Notes ===== JVC D-ILA projectors. Model [[http://tv.jvc.com/product.jsp?modelId=MODL028599&pathId=140&page=10|DLA-HD950]] can do 85Hz at 1024x768 (see [[http://resources.jvc.com/Resources/00/01/33/PC007182399-1.pdf|Instruction manual]] costs about $8000. There are also some display modes called MAC13", MAC16", and MAC19" (Mac specific?) THe top is 1024x768 and clocks just under 75Hz. DLA-X9 has no manual so there is no info on what display modes are driveable. Note that "Clear motion drive" is an interpolation technology that creates 120Hz from 60Hz by interpolating the other image.
