Considering some of the Stars Tours segments are the crispest 4D imagery I've seen across all the parks, I'm actually looking forward to seeing the screen work here.
It is the crispest because you are the closest to the screen and it is the smallest. I'm not sure which rides are 4K. Or even upscale 4K, like I think FJ is. But the new Star Tours I think is 4K, although when it opened 4K was rare, and even the back row is probably less than 20 feet from the screen. Front row on that ride is absolutely seeing full resolution, and it's not overblown.
Most other rides that are 4K (FoP) are on such large screens that it's more like 2 2k images on top of each other to make really tall images. So the resolution isn't that high. I thought it looked like a typical LieMAX screen.
Sorta like how Space's video was so incredibly high def when it came out, 1080p I believe. Because you were so close to it, and it was a resolution you weren't used to seeing at the time. Same with Shrek, which when it opened was amazing video, but now is simply standard 1080p projection.
This ride should definitely have 4K projections, but if they are as big as Spidey, they'll look like Spidey. Which isn't bad at all.
The only thing that could make a huge difference in picture quality at this point would be 4K at High Frame Rate like the Hobbit movies. I guess this could be that, but I sorta doubt it. I don't think there are any 4K HFR videos beyond proof of concepts. It will be interesting who brings that level of video first. I always find it weird that resolutions for new attractions are so hard to find.
And Yes, they are touting some ridiculous resolution for the Falcon ride, but that's on a huge, very wide, very tall dome. Most of that resolution will be peripheral for the front row and unseen for everyone else.
