Respectfully, I think I'll just rely on the good advice from JVC users on AVS for now,
Then after I get ~100 hours on the fresh amp, I can fine tune it with JVC's AutoCal software and a Spyder5.
That way as the bulb ages I can make my own (IN ROOM) corrections
rather than having the dealer calibrate a fresh unit without any of my room's parameters/treatments or screen.
I've already owned my current screen for 8 years, so did not buy Eastporters "combo".
(I may be new to 4K, but certainly not to Front projection).
I'm actually thinking of adding a fixed scope screen where my current wall mounted Kuro sits,
and keeping the powered drop down screen for 16:9 content.
I appreciate the work that professional installers and calibrators do,
but I'm more of a DIY guy for everything around my home,
in addition to cars trucks jeeps and motorcycles.
If I buy the tools I need myself the job is usually cheaper
and there are many others with the same mindset and knowledge willing to help for nothing.
Most recent discussion on settings by Javs here:
I certainly have no need for High Lamp mode, and did not simply put it on low to save money.
With a minimum throw of 12' to a 1.3 gain 120" screen its so bright its actually eye straining already
in a dark velvet bat cave unless I clamp down the manual iris to -10
There's also no need to "kill" the auto iris,
When playing HDR content the JVC Auto Iris is disabled automatically on the 2015 and up models.
