So recently I picked up 4K TV and thought if I made the leap for that investment, why not make my existing blu-ray library look better? Since I've been breaking the bank lately, I opted for a 4K upscaling player vs an actual native 4K blu-ray player. This being because I don't have any Ultra HD movies anyway, and wanted to upscale all of my existing 1080P content for something a bit easier on the pocketbook.I ended up going with the Sony BDP-S6500 4K upscaling blu-ray player. My experience with it thus far has been mixed. I'm not certain the "4K upscaling" looks any better than my old Sony native 1080P blu-ray player! Has anyone else had this experience? Perhaps my settings on the new unit are not optimal, although I believe I've done my research and have selected the proper settings to get the best possible picture. One thing I'm unfamiliar with on newer Sony players is the SBM or "Super Bit Mapping". I have read that this is supposed to be enabled for a better overall picture? Does anyone know anything about this feature? Does anyone have any experience with 4K upscaling that could share some words of wisdom? Does it sound right that blu-rays upscaled to 4K look no better than native 1080P content? Perhaps there are some hidden settings or tricks I am unaware of. Needless to say I am a bit disappointed in the picture quality, as I was expecting a bit more. I mean, I didn't expect native 4K quality, but I thought there would be atleast a noticeable boost!
