I don't have an opinion on the scaling and deinterlacing in the recent Mits DLPs because I have never sent them a signal that was not either native 1080P, or was 1080P out of device with first rate scaling and deinterlacing.
Yeah, that wouldn't be very helpful to me unless my U-verse box had a 1080p mode, and even then, it would probably still have problems with 480i->1080p content. Although i suppose a scaler like that would
be helpful because I can only have 1:1 pixel mapping with progressive signals, because for some reason the 1:1 mode doesn't deinterlace properly, giving the "flickery" effect.
The way my U-verse box deinterlaces is like this: It takes the 480i image, separates them into two 240p images, scales those 240p images to 540p images, and then reinterlaces them to 1080i. This is wrong and causes bad jaggies and a fuzzier image. If it had a 1080p mode, it would likely upscale each 240p image to 1080p at 60Hz, causing a very flickery image.
It's best to adaptively deinterlace the 480i image first, only deinterlacing the pixels that have moved since the last frame, and then upscaling that to 1080p. My TV does this with a 480i signal. I was wondering if these models did the same. Also, if the TV detects film source material, it shouldn't deinterlace, it should decomb, resulting in a 24Hz stream, which then it should apply 5:5 pulldown to 120Hz.
Does anyone here who owns these TVs know how the deinterlacer works, and how good the scaler is?
