Re: The 4K Thread...
No, UHD is the proper TV industry term for 3840×2160 video resolution.
"4K" is the DCI cinema industry standard for 4096×2160 video resolution with certain specific requirements.
A compliant screen/projector needs to display the full 4096×2160 resolution, with the image cropped in width or height respectively for other aspect ratios.
A 4K image could be higher inside the work-chain for handling of anamorphic images scanned from 4:3 film stock.
Back a few years ago the TV industry talked about introducing a consumer variant of the 4K video format. They discussed back and forth and eventually they settled on pixel-doubling "Full HD" to avoid getting black bars on upconverted content. The home theatre-phile press had been following the discussions though and the video format was much discussed in relation to Cinema-4K. The official name is "Ultra High Definition" which can be shorted to "Ultra-HD" or "UHD".
Then Sony started calling it "4K UHD" in their marketing to make it clear to home theatre-philes that this is what had come out of the 4K-TV process. Then others manufacturers followed.
5K is not an industry-standard moniker.
However, I could also mention that while the 27" iMac screen has 5120×2880 pixels, the smaller 21.5" iMac has a proper 4K monitor, with 4096×2304 pixels.
Both of them have the DCI-P3 colour gamut used by the 4K standard.
I have seen people calling 1440p/2560x1440/2.5K (or whatever you want to call it) for "UHD".
When 8K becomes more popular, what will they call that? SHD, or maybe Super Duper High Definition :lol
I am well aware of Apple's different PROPER 4K monitors
tis' a shame not every retailer/manufacturer is equally proper
Well...
It sounds like the marketing geniuses are basically bull****ting us by comparing apples to oranges.
If "marketing" claims that 4K is 4x the resolution, then it appears they are lying, since they're not comparing the same dimension.
"4x the resolution" suggests a 3840 (or 4096) compared to the 1080. But it SHOULD be compared to the 1920, right...? So its really more like 2x the resolution.
UHD/2160p is 4 times 1920x1080/1080p, but they are calling it "4K", which is wrong. If it were true, then 1080p would be the same thing as 2K(2048x1152), which it is not. And yes they are lying to us when they market a TV as being 4K when it is not. It is a bit like what happened a decade a go, calling HD TVs "HD ready", and then when you want to plug it into a 1080p source, it doesn't work, because the "HD ready" TV is actually only 720p(1280x720). After that they started calling 1080p TV "FULL HD" :facepalm
Just stick with the p-value system then! The higher the number, the better. Simple. 720p, 1080p, 2160p etc
so, pardon me for not being quick to digest info..
but my first impression from that is that I should basically avoid things that say UHD, because it's not true, 4K. is that mostly correct?
Everyone learns in different ways, at different speeds.
You don't need to avoid it, just be aware of the specifics and the ins and outs of it. Saying 2 + 9 = 4, does not make it true.
3D is a fun gimmick, but I worry they might stop supporting it.
They already did, several manufacturers (Samsung for example)have stopped producing 3DTVs. I want to replace mine because of some issues, and there are almost none to be found. And finding older models from say 2013/2014 and so on, is next to impossible. So they are still producing 3D films, sell them and they sell 3D glasses, buuuut TVs - not so much :wacko :facepalm
I am guessing they will rise again, but at the moment..... WTF.
What happens with all the 3DTV that were never sold? Scrapped? Dumped in some hole in the ground somewhere? "
I want one!", "
Take my money"
