There have been prototypes demonstrated of completely rollable OLED displays - not just flexible ones.
And it only has to roll up/down once every so often when you actually want to move the display, not every time. (though I can see why people might want that too)
Obviously durability needs work, but this was 4 years ago: https://www.youtube.com/watch?v=9OvTLg4i2_U
LG demonstrated an 18" rollable display earlier this year.

I watch TV and movies in our theater with a 110" (diagonal, 8' wide) Stewart screen, with a JVC RS-2 DILA projector. Long before that I had three (different) of the Sony SXRD's which I eventually ruled as unacceptable due to convergence issues on each one.
The screen is a micro-perf type so that the center channel speaker system can be behind it. At my ten foot viewing distance, the detail is excellent. At that, if you concentrate you can see the pattern of the micro-perf in the background of the projected image, at roughly the same visibility of the 1080p screen matrix. It doesn't seriously interfere with picture detail, the difference between 1080i and 1080p (upconverted or originating) is significant and obvious. Blu-Ray or other 1080p full bandwidth source is spectacular and obviously superior to any lesser format. 480p is all but unwatchable, as are regular DVD's, tapes, etc.
As Jim said, the good 4k's are quite superior. Even if only correctly upsampled 1080i/p is the source the pixels are so much smaller the detail appears to improve considerably. Quality of and the algorithms used in the upsampling are key. And native 4k can be amazing if the originating source is top quality.
But what I've noticed over the years, is that of all the people we've had over to watch a movie or three, none but one of them could actually read text on the screen from a Windows desktop at 1080p. Glasses or not. To me (I wear HD lense-type glasses), everything is sharp, clean and perfectly readable, (the movie info overlay on MC's Theater mode, for example, or text under desktop icons).
I don't think many folks realize how limited their vision is, and many of the docs doing the vision exams don't really press for detail (astigmatism correction as well) from their patients. It slips away from you slowly and until you can really A/B what you're missing, your evaluation/opinion of the difference between 1080i/1080p/4k on good display equipment just isn't going to be accurate. You just can't see the detail.
For me, 4k on the projector is next up, and I'd *really* would like to get rid of the micro-perf screen for a solid one, but the center channel presents quite a problem, since it would have to be relocated somewhere else (there just aren't that many options). We have an older Philips rear-projection 64" set in the living room, but it's 1080i only and while really nice in its time (1998) it's not up to snuff now. It can be replaced with a Sharp 70" 4k flat panel in the same opening, and that would be really nice. Soon.

Nice post. Thanks.
I looked at 4K at Best Buy again today. They had two TV's, side by side, 4K and 1080p. I looked at them from about 10'. It is a very clear difference. There is no question whether the difference can be seen. One has pixels. One doesn't.
My vision is uncorrected, and it's pretty good for an age challenged person. I can still pass the flight physicals without glasses for distance. Reading is a different thing. I'm lost in a restaurant with dim light unless I have glasses.

If you aren't already, you should use Red October HQ/madVR.
Configured to the higher quality scaling settings (i.e. NNEDI3) the results with lower quality content can be quite surprising.
Your SD material has to come from a good source though and be unconverted. (DVD to MPEG4 is an obvious degradation at this size)

At least part of this is your projector.
3-chip projectors, the older JVCs in particular, are very soft.

That's just due to age (Presbyopia) so there isn't much to be concerned about.

I had the same dilemma. I ended up using 4 centre speakers - 2 above the screen, and two below. They're wired in series-parallel, so they present a total 8 Ohm load to the receiver. Dialogue sounds like it's coming from the upper centre of the screen
