• New TV and Home Theater

    From Al Kaiser@1:142/926 to All on Thu Mar 15 10:08:19 2018
    Looks like I'm being forced to join the 4K revloution. My 3D HD TV crapped out and I have to buy a new TV. I went with 4K because it would not make any
    sense to stick with HD because everyting is slowly switching over and even the "small" 32 inch screens are going 4K. The TV manufactures stopped making 3D sets in 2016 and there is no "old stock", (with the exception of one 65 inch screen which is too big for the small room here).

    This also means a new 4K player and 4K receiver. The HD ones will not pass a 4K signal. I went with the Sony 49 inch screen which is only 8 inches bigger than my 40 inch that I have now. Also went with an Onkyo receiver and LG player. A mix of brand names but the best combination for what I am doing. It all arrives Friday and I'm sort of excited.

    The 3D TV's main board "went". It keeps jumping out of "Cal Day" into Dynamic mode. Put it in Cal Day and it jumps out in about 20 minutes. This is the second time the main board went, the first time was replaced and recalibarated under waranty. Wonder if they will get it at the recycle center plug it in and "save it"? I'll bet someone there will get a cheap find. (How much stuff at the recycle centers gets repurposed)?

    So why did they stop making 3D TVs? For a while you could buy a 3D 4K TV. And if this had happened a year or so ago there proabably would have been some stock around and I could have had a 4K 3D system. 3D failed for a number of reasons.

    The biggest was that the glasses that each manufacturer needed to supply were not compataable with different sets. You could not watch a 3D movie on a Samsung with a set of glasses from a Sony or LG set and visa-versa. Another reason was brightness. They did not address the brighness issue with 3D movies. You always were looking through a set of darkend glasess. Even in the theater the movie is "darker" than a normal film, tho the darkness of the theater compensates some. They would have had to overly brighten the Blu-ray for home theaters which would have meant two version on a disc because the
    2D version would be over saturated by just showing "one eye" for 2D. Finally media. The meadia was not promoted outside of Blu-ray releases of theater versions. And even some of the theater versions were never released in 3D. Also the movie industry made relativly few 3D releases compared to "Real D" as it was called. And lastly the broadcast industry never supported 3D outside of a few sport specials.

    So what is the future of 4K? Will the broadcast industry pick up on it? Will HD die a slow death like the 8 Track, Cassett, and even standard the DVD which, though you can still buy the media, players are becoming harder to find in stores because the price of a Blu-ray player has come down to the same price level as many bargain DVD players?

    High end, large screen 8K TVs are supposed to be out for the Christmas season in either 2019 or 2020, manufactures are being tight lipped about when but have been actively working on the technology and like 4K will be introduced with a price tag in the thousands. But look how little time it took for 4K to come down in price and screen size to where HD is now. In 5 years you may be unable to buy an HD screen or DVD player.

    Technology is always moving forward.

    So, wait... I thought 4K was just a high-end HD. Is it something that
    replaces it instead?

    4K is the next step up in the pixel resolution. While HD is 1020 X 1080 pixels and somtime referred to as just 1080P or more commonly known as HD. HD can also be 720 X 960 if you rmember when HD TVs first came out they were all 720 Plasma screens, (That's where the "P" came from when the flat screens were being introduced). The glass screens which still had the gun are interlaced, my brother still has a 1080I TV which throws off the COX Tech because he sets the box on 1080P and wonders why there is no picture.


    4K is also known as UHD and all those new names you see in the store is 3840
    X 2160 pixels. I have not heard it referred to as 2160P it is better known as 4K or UHD.

    I have not seen any specs on 8K but I'll bet it will probably be 7680 X 4320 pixels if they follow their current standard of thinking. Problem is they can only go "so far" within reason because the media like Blu-rays are 50 GB max and you would have limits on how large a movie could be put on a disc. Also the cable companies and broadcast media only have so much bandwith to fit a signal and audio they may not have the ability to to transmit an 8K signal without compressing it to fit the bandwidh now. Cable companies are compressing the HD signals now and that is why if you look side by side at a cable's HD signal and the same broadcast signal the broadcast signal is noticibly better.

    We will have to see where the technology takes us.
