Less than a year ago Youtube enabled full HD, 1080p, video resolutions on Youtube and most people thought that 1080p was going to be the top resolution on Youtube for a long time to come.</p><p>4K videos raise the bar by running in a resolution of 4096 x 3072, that&#8217;s almost four times the size of the full HD resolution.</p><p>But 4K videos raise the bar not only resolution wise. The hardware requirements to play those movies on Youtube have gone up a lot.</p><p><span
id="more-28092"></span>Youtube visitors need a ultra-fast broadband connection and a computer system capable of displaying the videos smoothly in the web browser.</p><p>First user comments in the <a

DVD sales do still top Blu-Ray sales by a large margin and it is not likely that this is going to chance anytime soon. But Blu-Ray is obviously not the only technology benefiting from full HD resolutions. TV stations all over the world are slowly (depending on your location very very slowly) beginning to offer HD TV. With all that said it feels surprising that TV developers are already showcasing the next generation of TVs that offer four times the resolution of full HD displays.</p><p>The so called 4K standard offers a resolution of 3840&#215;2160 which equals four times the resolution of the current full HD standard. This would theoretically mean that the 4K TV is capable of displaying four full HD screens at the same time.</p><p><span

href="http://ceatec.com/2009/en/download/index.html">Ceatec</a> convention in Japan last month. Other companies like Sony also showcased their 4K TVs already.</p><p>But who needs such a display? There are definitely some uses in the high-end professional market but what about end users? The main culprit here is that end users won&#8217;t have anything to watch or play on these devices for a very long time. Especially considering that the full HD standard has not even reached a critical level of distribution. But then again, who needs 4K if the next standard called Ultra High-Definition Video (with a proposed resolution of 7,680 × 4,320) is already in development?</p><p>What&#8217;s your opinion on the matter?</p> ]]></content:encoded> <wfw:commentRss>http://www.ghacks.net/2009/11/07/full-hd-that-is-so-yesterday-get-ready-for-4k/feed/</wfw:commentRss> <slash:comments>8</slash:comments> </item> </channel> </rss>
