Question: Have you tried any 60 fps content at 60Hz on a raster scanning projector? I'm asking because I've read about distortion characteristics when objects move as fast or faster than the scan can complete it's downward path.
I've played many perfect 60 fps at 60hz games on my sample laser projector, and it rocks. I have zero complaints in terms of motion. CRT skew can be solved, too (stay tuned!)
But as Bailey mentions, and as I've written in my review of the Sony Pico model (which I briefly owned and then returned due to excessive banding), other aspects are more pressing, even IMO more than resolution. Like I said, banding is one. Speckle is another.
Resolution is indeed very important, but unless you have the lumens to make a super large screen, there's IMO other low-hanging fruit that should reap higher dividends.
I'm perfectly satisfied with my w1070's 1080p native resolution at 140 inch diagonal size.
At 80 inches or less, I think 720p is probably fine, especially when so much of what we watch is ultra-low-FPS 24p blur-fest anyway, which, even if you interpolate it to 60 or 120hz, would still be pretty blurry.
Removing blur that's baked into the content is an ill-posed, quote "hard" problem.
Reinforcement learning that hallucinates detail from many prior frames could be a win there.
De-blurring a frame priot to interpolating it (so that it's both smoother and sharper) is a similar, but harder, problem to 4K or 8K upscaling, and machine learning is kicking ass on the new 8K TVs apparently. The future really is bright for high res, but it's also very bright for high motion res, too. And IMO motion res is where both content and displays are lacking the most in, so to me represent the low-hanging fruit. Raster-scanned laser projectors are a natural fit to replace CRTs as the new King of motion resolution. The old king is dead, long live the new king! These little guys are really exciting and fun, even if they aren't capable of replacing your main display (yet).
With full-persistence displays, which virtually all traditional DLP or LCD or LCoS projectors are, since otherwise they'd be throwing away lumens to reduce blur, you're better off simply reaching for 120hz and using interpolation if you're concerned about motion res, then you get full lumens and good clarity with even reasonably fast motion vectors.
Black frame insertion is only a good idea on a projector if you're already so overwhelmed by lumens (say, a fresh bulb), that you would use an ND2 filter and can afford to throw away half the light. In this case, yes, use BFI and double your motion resolution (or halve the persistence / blur, same thing).
I desperately want a decent-performing 1080p 120hz DLP, but I think these little guys are going to fill a market niche for enthusiasts like AVS forum members and gamers, who appreciate the importance of good motion clarity (with or without frame interpolation), great contrast (despite comparatively lower lumens, vs a TV or even other LED pico projectors).
