Now that is something that I would never have discovered.
I nearly never discovered myself.
Luckily, I was fortunate to have 2 broken projectors last year. If my 8 YO plain HD PJ didn't break and didn't get a defected new projector I would never have discovered how amazing 3D BD's are. Also apparently I got 2 from one of the last batches of Vanity 1.4. So best breakage/silver lining my system ever had.
Last year I got a new JVC 4K projector. It came broken. The nature of breakage was with certain material, including Oppo's screen saver, would render the projector unusable.
JVC did one of the most honest things I have ever experienced in professed high end A/V. JVC sent me a second one so I would never be down. If only audio companies were that honest than we would probably not be in this MCH DAC mess.
I have never watched 3D because I have rule: A tech needs 1K sources for me to support. Learned my lesson with LP. I wasted hours auditioning until I realized the lack of sources.
Obviously I tested EVERYTHING with the replacement. The JVC 3D was amazing! I also never owned a movie in my life and still get my BD's from Netflix mail much to all my guests amusement. Mainly because I rarely ever watched movie twice. For 3D I'll watch twice. There are only around 200 non-cartoon 3D's and Netflix doesn't rent those so got them all. My kids liked around 30 cartoons. I have room in my rack for most. Very nice how BD's come with these slipcovers.
Broke 2 of my rules for 3D. Well, 3 if you include the Vanity mod. I never thought I would mod.
4K BD's have even fewer but they are trickling out about 2-3 new relases a month + a few old.
Wonder why Kaleidescape, the only other 4K high rez audio tech besides physical media, doesn't rent? I would probably get it. Good (plot wise) 4K movies I would still get the BD since it never uses HDMI and 4 digital devices vs 3.
My firestick is only 3.5 digital devices since it uses the Oppo's USB power. I upgraded the Oppo to more power much like Kirk's usual request. I got the Khan clone, um, I mean, Clones v2 powersupply.
