JVC DLA-X790R D-ILA Projector Review Settings

Unit-to-unit sample variations, the viewing environment, and the source — and, particularly for a projector, the screen size and gain, the distance from the projector to the screen, and the lamp age — might render these settings less than optimum. They are provided here only as a potentially useful starting place.

The settings that are most likely to translate reliably from one sample to another are those involving specific features with only a few selections, such as Gamma and Noise Reduction. The ones most likely to be subject to sample variations are video controls offering a wide range of adjustment, such as white balance (grayscale) and color management (where available). Even relatively small differences in the common control settings — such as Contrast, Black level, and Gamma — can shift the white balance, though the resulting visible change may be minor. Production tolerances can do the same.

We strongly recommend that you find the optimum basic video settings for your sample by using one of the many available display setup discs, such as Digital Video Essentials HD Basics (Blu-ray). These will help you to correctly set the basic controls: Brightness (Black level), Contrast, Sharpness, and sometimes Color and Tint. Experimenting with the more complex color calibration and other controls in the user menus will do no harm; the changes may be easily reset. But adjusting these by eye is unlikely to produce an accurate result and is no substitute for a full calibration. The latter is best left to a trained and properly equipped technician such as those certified by the Imaging Science Foundation (ISF) or THX.

The settings here are for 2D only. The display was not calibrated for 3D.

Great review Tom on the excellent JVC-DLAX790R projector.
But you floored me with the revelation that your reference screen is a StewartFilm widescreen, 8' wide no the less.
I'm afflicted with a serious case of screen envy.

While I'm not ready to migrate to 4K yet I've yet to decide on a tv or projector when I do. I've always been an early adopter of new technology - but it has also bitten me in the butt a few times - and that's why I'm not jumping into 4K yet since it seems that the dust has not yet settled on that. Right now I'm more inclined toward OLED than all other technologies. With the size of screens getting larger and larger (excluding the high price), the size of my room, why pay for a projector, a screen, installation, and more "parts" to worry about?

I was curious if you ran your review with the iris in Auto 1 , Auto 2 or with it off ? Auto 1 tends to crush blacks and seems to add more processing or treatment to the image. i prefer Auto 2 for HDR and Auto 2 or no iris for SDR.

In the settings section for HDR, the configured review setup had
"Maximum Manual for Lens Aperture". Does that mean 0 (the mathematical maximum) or -15 (the aperture maximum, if that is even true)? I am confused which one it is, so any feedback would be very helpful. Thank you.
