Brief personal explanation:
I just recently completely a 157" screen in my garage I use in conjunction with a 1080 Panny PJ, as some are aware. Now, I'm not here to beat my chest about it- there are a TON of other executions on AVS and elsewhere that outperform it in every regard- just sayin' FYI.
That said, I simply could not ignore the reality that at 20 or so feet, I was/am extremely challenged to extract all of the detail. Basically, if I begin to move closer to the screen, I discern more of the content. Simple as that.
Now, before anyone makes the determination that I'm crazy, blind, near-blind, or any combination of the aforementioned, please understand I just had my vision checked 7 months ago and I'm 20/15 according to my doc. I am 100% confident my sight is at least as acute as most and certainly that of the "normative" 20/20.
SO then, after being substantially unmoved by the 4k displays I've seen in various arenas...crucially, that's at a REASONABLE viewing distance, I am to the point where I'd really like to partake in a controlled A/B A/B/X of both 1080 and 4k if it is at all doable. Ok, maybe just for fun as we may discover.
Again, I realize this could/will be extremely arduous, for many reasons. Still, I'd like to lend the ear/wisdom of the many experts here to ascertain if such a project could be undertaken with anything resembling an equitable playing field.
I'm just going to throw out the problems/areas-requiring-attention that I see and their possible resolutions...heck, if we really don't have interest in this to begin with there's no sense in wasting mine or anyone else's time in the first place.
Here I go...gulp.
I. Source material:
A. Blu ray sounds nice and easy...with of course the massive distinction/exception that it's 1080, natively.
1. Reality: for now and the foreseeable future, there will be little to no 4k media, so blu ray as a comparable source is fine.
2. Still, doesn't it have to be native vs native? The upscaling of 1080 onto a 4K display surely puts the 4K PJ/display at a bit of a disadvantage. Shall it be native 4k material for the 4k display device or nothing?
Your thoughts? I realize there is indeed 4k media available so the latter could easily be done. Heck, we could do BOTH.
II. Display/PJ Selection and Calibration
A. To me this seems to be the largest obstacle. How on earth do you select "comparable" 1080 and 4 K display devices? Of course common sense dictates it should be an identically tech'd PJ vs PJ or an identically tech'd flat panel vs flat panel.
B. But then, stay within one manufacturer, right? That way you can (likely) calibrate them much closer/have much more similar screen types? I realize this is a bit of an "obvious" assumption, but many more here know much more than I in this regard.
C. Most imperatively: can we achieve: indistinguishable color, brightness, contrast, etc? Or at least nearly indistinguishable- especially from a 2.5 PH (or whatever we decide upon) distance?
Even more basically: can we dial in two identically-sized displays extremely closely so that they can be fairly judged JUST from a detail/resolution standpoint? This of course may be impossible. Asking nonetheless.
III. Viewing distance/comparison methodology
A. I of course cannot speak for anyone else but the 2.5 picture height distance is a winner for me. I realize some sit closer. I also realize some won't ever sit that close in their life. Still, it seems to me that it's a very reasonable starting point...splitting the difference between the aforementioned while getting pretty close for a good number more.
My 157" screen for instance puts me at 17.5 feet for the 2.5 PH which is the THX "recommended" distance for my screen. Honestly, many times it seems too close to me, but, there you go. Thoughts?
B. Are their any drawbacks to the screens being equidistant from our defined viewing distance for the sake of comparison? Thoughts?
C. Darkened room seems obvious to me. Thoughts?
A. I'm running a bit short on time but I wanted to get this out there. I am convinced these mono e mono comparisons are going to be popping up everywhere at some point so I guess I/we could let others do the heavy lifting and simply enjoy (ok, let's be honest, as this is AVS: ARGUE ABOUT) the results, but where's the fun in that (using someone else's results, that is )?
I'm sure I left much out in the above, please feel free to add other obvious and not so obvious hurdles.
This could be very fun AND put absolutely nothing to rest...what else could we ask for on AVS?!
thanks for listening and contributing!
