  • What you might not know about the 4K/Ultra HD TV


    Everybody is talking about the latest advancement in TV technology, the 4K TV, also known as the Ultra HD TV. Sooner or later, you are bound to own one of these, so this is a sneak peak of the facts behind the entire buzz.

    High Resolution

    UHD’s minimum resolution is 3,820 x 2,160, which is around four times the 1080p resolution. The higher resolution is not the only great thing about the improved picture that 4K TV brings to the table. There is talk of the Rec 2020 which will be an improvement in the current 4K TV standards. It will bring improvements to the image color and frame rate to bring an entirely better picture to TV. This new standard will be introduced to TVs sometime in the future so that is something to look forward to.

    What is the difference?

    The extra resolution will probably not have so much impact if you are getting the average 50” TV and sitting around 10 feet from the screen. But sitting closer to the screen or getting a larger TV or projector, around 80” gives you the high quality view that you most probably desire from a 4K TV.

    Ultra HD Vs 4K

    The two terms are used interchangeably for the new high resolution TVs. Officially, 4K is the cinema equivalent for the high resolution picture, around 4096 x 2160.

    Most people will probably use 4K instead of the more appropriate Ultra HD because it is easier to say and type. But as long as the message is clear, I don’t think it matters which name is used for the TVs.

    HDMI 2.0

    This is the new HDMI standard coming, moving from the HDMI 1.4. The current HDMI cable will work with your 4K TV but the HDMI 2.0 allows higher frame rates (60 frames per second) from the 4K signal, a double of what HDMI 1.4 can support.

    Finally

    The development of the Ultra HD televisions has led to the abandonment of plasma TV. TV production companies are finding it increasingly difficult to make Ultra HD plasma TVs.

    Although there is still not enough content for Ultra HD, the displays are clearly the future of TV seeing that prices are already coming down, making it more affordable day by day.

    In a few years, Ultra HD TVs will be more affordable, better, and there will be a lot of content for the displays. Even if you do not get one now, they will probably be a much better investment in the near future.

  • Panasonic: High hopes for 4K TV


    Panasonic has come out to strongly support their latest technological advancement in the 4K TV technology, claiming that it is bound to succeed as there is more drive to it as compared to the 3D that has really failed to gain attention in the market. Although Panasonic 4K TV costs approximately $4100, which is quite a large amount to be spent on a TV, they are optimistic that the 4K TV will rise.

    The product manager of Panasonic, Craig Cunningham on being questioned by Trusted Reviews  on whether the drive that is behind the 4K is greater than the 3D  revealed that the race to shift to 4k and to get it out there where more and more content is going to be shot in 4K. According to him, 3D still has a place in home entertainment and that they have learnt from the failings of 3D in that there was lack of content  when the 3D was unveiled hence causing the technology  not to rise. He pointed out that the main concern for the customer is if the 4K TV is great and whether they would be able to get content to play on it.

    Despite this concern the Japanese manufacturer hopes that the 4K TV will be an easy sell especially in the UK market. This is because it is easy to see the deference in picture quality between the HD TV and the 4K TV.

    Despite the fact that the lack of 4K content will make the rise of 4K a little bit slow, Panasonic is confident that by the end of the year there will be a lot of 4K content  available . They are also taking measure to facilitate this by enabling their cameras to shoot 4K so that more 4K content can be created. He also added that sporting events could play a major role is the rise of 4K.

  • A bigger screen for less money: use a 4K TV instead of a monitor


    A 4K TV could be your best chance of getting great and efficient monitor service without spending an extra coin. According to Brian Hauer who wrote a piece on Tiamat, programmers will be happy to discover the $500 Seiki 39” 4K TV which works very well as a high-output display. Anybody else who works with many windows open will appreciate the productivity enhancement that the TV will add to your work considering other good and affordable 27” or 30” monitors will cost you $400 – $650..

    Just like the other imperfect HD-TVs in the market, the Seiki 4K TV has its set of set – backs according to Hauer.

    One of the most notable draw – back with the TV is that at the 3840 x 2160 resolution, only 30Hx can be supported by the HDMI 1.4 ports. The 30Hz limitation also applies with the Lower end GPUs at the same signature resolution. A GPU belonging to an old desktop PC does not have the capacity to support 3840 x 2160 so if that is what you are using, you will need to stick with it for a while.

    Trouble with the 30 Hz is mainly experienced in screen mouse movements and that is not a big enough issue for most of the users out to exploit its good resolution. The Seiki might not also be the best screen to use for gaming but many other functions perform great with the screen.

    Either way, the Seiki 39” 4K TV is much better than the regular monitor because of the larger number of pixels that the TV offers.

    At this point I think it would be safe to say that 4K TV is definitely built for programmers.

  • 4K: Is Ultra HD the Next Big Step?


    The next advancement in the TV sector is already here and when compared to the standard HDTV, it makes it seem faint and overrated. The new technological format known as 4K was primarily designed for digital cinema projections due to its high resolutions. Compared to a 1080 HD TV, 4K offers up to four times the HD resolution. Due to this high resolution, 4K TVs are very expensive but the prices have already started rationalizing.

    According to CES 2014 show, 4K is the next big thing in the TV sector and that is why many manufacturers are trying to shift to this new product so as to attract the demand market. When used in digital cinema projections, 4K delivers up to 4096×2160 pixels of quality images. However when put in a TV, the resolution changes to 3840×2160 pixels which is 4 times more than the standard HD resolution. Since its resolution is more than that of the standard HD TV but less that 4K resolution, it is termed as the Ultra HD TV.

    With the 4K resolution and the Ultra HD resolutions being slightly different, the 4K cinema pictures will have to be scaled down or chopped off at the sides. This means that you will lose 6 percent of the image on both sides of the screen. In spite of the differences between 4K and Ultra HD, It has been noted that Ultra HD provides a certain leap from the standard TV in terms of image sharpness and detail. Switching to Ultra HD is the next step in the industry, profiting not only to the buyers but also the manufacturer.
