5040, not 5030.
I've had JVC's in my room on two separate occasions. The first time I compared a professionally calibrated rs500 vs a 5040 and when calibrated I liked the rs500 better due to better blacks (although it wasn't as big of a difference as you would think). However... here is the thing - I didn't like either one of them when calibrated. They were both too dark and I would never watch them like that so it was kind of a wash.
Fast forward a year and I found a great deal on a rs600. Unfortunately it was damaged in shipping so I had to return it but the damage was all cosmetic and the dealer told me I could try it out for awhile while we sorted out the claim with UPS. So, I assumed I would like the 600 better and would soon put the 5040 in the classifieds. I tried every video setting possible including many gamma settings recommended by owners of the JVC's but I just couldn't get it to look as good to my eyes as the Epson.
The JVC is indeed brighter when both are calibrated but since that is irrelevant to me, what really matters is if the JVC has a mode that is as bright as Epsons "Bright Cinema" mode and I just couldn't re-create that with the JVC.
IMO bright cinema right out of the box looks better than any of the user settings on the Epson 5040 thread (ha, and I've tried them all I bet) and it also looks better than anything I could get out of the JVC. To my eyes bright cinema maintains very acceptable blacks (even compared to a calibrated JVC) and the colors still look great while at the same time easily giving me all the brightness I would want on a 12' 3" wide scope screen. The image just really pops, even beyond 2000 lamp hours.
I also liked the tack like sharpness of the Epson compared to the more filmlike look of the JVC, movement looks better/more natural to me on the Epson, and the down time between switching sources on the JVC is ridiculous prompting my wife to ask me if I broke it when I switched sources.
I know I'm an outlier and even though there are others on the forum I have found that like Bright Cinema out of the box better than anything else, I really don't care about that. I could be the only person on earth with these preferences and that's all that matters to me since it's my eyes.
