The only thing is, if you play back anything higher than that profile, it'll still be applied and your PC may not be albe to handle it (like 1440p or 4k video, or maybe 60fps).

I only watch Blu-rays and they are all 1920x1080p at 23.976 fps. with the exception of a few from the UK at 24fps.
Maybe at Christmas time when they actually come out with 4K discs, but the cost of upgrading everything would be so expensive, it wouldn't be practical.
The least expensive 4K projector right now is around 8,000.00$ US, then I would need a new MoBo and some sort of super processor to interpolate frames at 2160p. The least expensive piece of hardware would be a computer based Blu-ray reader to read the very small "pits" on a triple layer 4k disc. (I'm guessing about that)
Although things are supposed to be filmed at 60fps with 4k, so there won't be any need for interpolation anymore.
However I did read an article that they are still going to stick with 24fps (23.976fps), so I am guessing that even though the master may be at 60fps, they will be downscaling it to 23.976fps.
I could never understand the publics need to stick with such old technology _ 24fps. I occasionally turn the interpolation feature off and it becomes intolerable to watch, eg. The Tale Of Princes Kaguya _ the opening has a pan of a bamboo forest that is so irritating to watch with out interpolation that IMO, can't be watched and yet people do. The public has some how convinced itself that the director intended it to be that way _ really _ it looks like shit ! 

There is so little information about it, that I just can't concern myself with it now. 

The strange thing about that new Sony 4K projector is that it can't even accept a native 4K input, the specs clearly show this.
The only ones that can are not truly 4K either, they are 1080p, and they use a method to shift the pixels diagonally to increase their density.
That's JVC and the newest Epson.
So the Epson and JVC projectors would be downscaling the 2160p input and then applying the projectors hardware to upscale it to their pixel shift technology.

Anyways, I'm getting sort of off subject here...

Well, SVP itself has no specific profiles for video over 1920x1080@24.

Yeah, so what SVP does is that any video of a higher resolution and the like will use that profile, and your PC may not be able to handle it then.

The only thing is, if you play back anything higher than that profile, it'll still be applied and your PC may not be albe to handle it (like 1440p or 4k video, or maybe 60fps).

Well, SVP itself has no specific profiles for video over 1920x1080@24.

Having one profile keeps things simple. 

I noticed that SVP seems to work better (less artifacts) when it chooses a profile of 1920x800 as apposed to 1920x1080.

Sometimes it can choose one or the other for the same movie if I shut MPC down and restart it _ it's random. Sometimes it will change if I pause the movie.

I'm thinking if I delete all the profile except for 1920x800@24, that would be the better thing to do ???

For the most part things work quite well and I may be splitting hairs, but I would like an explanation to this, of possible.

Thanks...
