Edit: 12/13/2015 - adding screen adjustment mode table
edit: 12/14/2015 - added link to Manni's excellent primer on 2016 JVC Autocal software.
JVC makes it hard to find the user manual - for those interested, here is a PDF of the full manual for the 2016 models.
Basic settings / Menu options
The first option you choose when setting up the projector is the 'Picture Mode
'. examples, film1, Thx, Natural, etc. I always go for 'User1' to start with because this becomes my '2D Low' setting (you can change the profile username unlike the Sony which is a PITA).
Once this is selected, you can then choose the 'Color Profile
', 'Gamma Setting
' and also the 'Color Temp'
From there, you can set user adjustments for each selection. So for Color Profile in 2D low, I select 'Custom1' with the CMS turned off. This is as close as it gets to an R709 setting with good saturation tracking. For Gamma, I choose the user mode where you can set a specific baseline such as 2.3. For the color temp, also a user mode where you can set a baseline of 6500K which then allows specific adjustments to the gains and offsets.
So when I'm done calibrating the projector, I end up with 3 picture modes. 2D Low, 2D high and 3D high. When going into 3D, you must manually change the picture mode or it will be in 3D, but in either 2D low/high picture mode, depending on what you were watching in 2D.
Here are some example screenshots to follow from the description above:
In this screen, you can see I renamed 'user 1' to '2D Low' - this makes it easier to identify which mode to select.
going into the picture mode menu, you will see the following options. If you would like to lower the iris, change the 'lens aperture' setting to manual - then adjust the iris to your liking - then turn 'auto2' back on. This will now use the dynamic iris, but only go as bright as your set iris level.
to understand what the 'Clear Black' setting does - look at the description and example below. I like to keep it on low or medium and iris set to 'Auto 2'
going back to the picture mode settings, here is what the 'Color Profile' setting looks like
Also for 'Color Temp' - you see I started with a 6500K baseline, this wasn't perfect out of the box and needed some adjustment as expected. I had to pull down some red and green for the gains and green and blue for the offsets. Greyscale tracking is good when adjusting 30/80 IRE but will need some help @ 5-20 with the help of the auto-cal software + meter.
Note: this is just for my specific JVC, most projectors will be different. Without calibration equipment, leave these settings at 0.
Gamma Setting - set it to 'Custom 1' and choose 2.3 as the baseline.
Details from JVC on the Picture Tone, Dark Level and Bright Level settings.
My recommendation - find a number of scenes in a movie you are familiar with and try the various adjustments. You'll quickly see what each setting does and can adjust to your liking.
This is obviously not a substitute for a full calibration, but a good general overview of how to get started - especially if you have never worked with the JVC menu system. If you have any questions, please post them in the thread for discussion.
** Please see this link for a detailed discussion on the JVC auto-cal software. Currently it requires a Spyder 4 Pro or Elite, Spyder 5 support will be added sometime in Q1/2016.
enjoy your new JVC!
