The only projectors that are truly sharp, are the high-end single-chip DLPs, since they do not suffer from convergence issues, and high-end glass optics put out a pretty sharp image with little chromatic aberration.
There was a really nice Samsung a few years back that Joe Kane worked on - one of the best examples of this.
It's still much softer than a flat-panel of equal size though, and SDE is a common complaint with DLP. (since they're actually sharp)

That's true and probably why I like projection, it is more like 'going to the movies'...or maybe I'm just old and the new resolution craze doesn't do it for me
I used to make projectors when LED was only (commonly) in computer applications, and commercial pj's were really expensive. I've experimented with many optics and such, back then there was no 1080 content so the quest was always getting the best DVD image. I guess I just don't care about infinite resolution very much, film always seemed so "real" to me and DIY projection was my only tv source for many years

It's a lot easier to build a rollable display (like a motorized projection screen, only it's the TV) than it would be to have you "paint" your display on the wall—unless you're talking about painting a projection surface.

You misunderstood (because I didn't explain) what I meant by more likely. I didn't mean "more likely to come first". I meant "more likely to completely replace current tech".
Large-scale rollable displays, used as wall coverings, are likely to be developed. They ARE in development now (as are self-organizing nano-paints). Unfortunately, they will also be incredibly expensive, not just in the short term, but likely permanently. There are a variety of issues, but the main one is:
They will almost certainly be incredibly fragile and easy-to-damage during installation. Once installed, I think they'll be able to make them quite robust (eventually), but because of the power delivery and control requirements for building a large-scale array of "strips" it is very unlikely that we will see "install it yourself" versions of these anytime remotely soon. Of course, some revolution could happen, but the stuff in development now certainly has these issues.
That means, professional installation is required.
That means, it'll be a < 1% of households thing, for the foreseeable future.
Paintable displays could solve this issue, by and large. Of course, we're talking about things nowhere near production ready, so they may never come to fruition at all. But... It isn't as far-fetched as it sounds. All I can say is people I trust, who would have reason to know, have told me as much.

The logistics of being able to literally paint a display on a surface seem like something which is unlikely to ever happen.
I just can't fathom how that would work at all.

Think of it like a motorized, tab-tensioned projection screen.
All the electronics are in the base, and the screen rolls down from it. (or up)
If you can hang a roller blind, you could install one of these displays. It would arguably be easier than wall-mounting a flat panel.

I think something like flexible OLED will make a lot of interesting things possible.

If they can pull that off, perhaps. But the current tech is flexible only to a point, and certainly cannot be rolled even once, much less repeatedly. Each pixel needs wiring.
I could certainly be wrong. Very little of this is based on first-hand knowledge, but... As I said, people whom I know and trust well have worked on these exact technologies in research, are pretty skeptical that flexible OLED will ever get there, like people widely envision.
I don't profess to fully understand how the paint thing would work, but I believe the designs are for a self-organizing mesh network of individual pixels. They organize themselves into a "display" after application. I don't understand how power would get to the pixels at all, though (and perhaps that is the biggest stumbling block, in addition to simple miniaturization and manufacturing process, which is always the rub).
