I wonder if running a 4k source to a 1080p plasma will yield enough of a benefit to get enthusiasts to adopt the format before a suitable technology(ie, NOT edge-lit led's) is used for 4k displays.
you may be right, that there will be some improvements with UHD that has nothing to do with pixel count. I just think it's too bad we couldn't get those with a 1080p resolution so it'd still maybe fit on a currently available BD disc. there's also already a bunch of 1080p displays that support rec709(I think that's the new one?) so maybe we wouldn't even need to buy a 20k tv to see this.
I am not talking about upscaling of course. Upscaling brings poor quality because of interpolation that must be done to create new pixels and I do not like it. But downscaling is different story. You're not permanently losing the pixels. The pixels blend giving more details on even lower resolution display. So, for example, if you play future 4K Bluray movies on your F8500, such movies do not automatically become a 1080p BD just because yours is only 1080p. You will also get FAR superior bitrate, same as those playing on native 4k TVs. Sure, there will be a slight reduction in detail because downscaling can only go so far, but the result still will be far closer.
figo123 is not wrong stating he prefers 720p over the 1080p. (I apologize if that's not what you said, figo123) Having used both an LG 720p plasma and 1080p Panasonic plasma, I'd say a 720p plasma still handles today's majority of contents better than the 1080p ones. For the 1080p displays, Bluray is the absolute minimum to enjoy optimal picture. Unfortunately, vast majority of today's contents have less bitrate than BDs, and that's where the 720p displays shine. Youtube for example offers 1080p music videos, but their bitrate is a far cry from a proper 1080p such as BD. Sure, my Panasonic S64 can pixel match those 1080p Youtube videos, but will also get nasty compression artifacts it doesn't even matter whether it's pixel matched or not. My previous LG plasma in comparison, handled Youtube videos with beauty. Because those 1080p videos had low bitrates in the first place, downscaling only loses extremely slight details, but keeps out all the nasty compression artifacts to minimum too. Many people make mistake assuming 720p displays has to choose 720p option, and 1080p display 1080p option. That's wrong. Both displays should choose 1080p. Youtube has a restriction on bitrate depending on the choice of resolution, so a 720p video will have far smaller file size than the 1080p one, they are not equal. Heck, even a regular song with a single picture uploaded to Youtube sounds the best when uploaded at 1080p.
Unfortunately, this is exactly what will happen when 4K videos get mainstream over NetFlix and iPhone. They will simply blow up the resolution to 4K without any regards to bitrate and consumers will be tricked thinking they are getting far higher PQ than what they are actually getting. Fortunately, that's where the H265 comes into rescue. These next generation codecs have twice as better compression ratio, so even the bottom of the barrel will still look much better than what we're seeing today, but bitrate will always remain important and I doubt streaming will reach a point where we wouldn't need a 4K BD anytime soon.
So, my future plan is as follows. 1. Get a 64 inch Samsung plasma wtth proper HDMI 2.0 support. 2. Let the TV downscale 4K Bluray to 1080p.
Even if this method is not attainable, I can still do the same on my Panasonic S64 as long as I use my PC. There may be a future 4K BD player that will properly downscale a 2160p movie to 1080p. Or I can use an external video processor. The choices are endless. I've already seen what the 4K video is capable on my Panasonic S64, and will be anxiously waiting for the 4K BD. A 1080p plasma plus 4K BD combo will be what I will be using to tide over until a 4K OLED gets affordable.
