NETFLIX 4K GRAINY 1080P

Our tests were carried out with the Samsung 48HU7500, Sony 55X8505 and Samsung 65HU8200 to look at a spread of different screen sizes. As we love both, this task has proved no hardship but to keep comparisons simple, weвЂ™re concentrating on the second series of House of Cards, as thatвЂ™s what weвЂ™ve spent most time with. The Netflix 4K catalogue is not large but if youвЂ™re a fan of either/or House of Cards and Breaking Bad, youвЂ™ve got a fair bit to go at with both series of the Netflix original, HoC, and all five series of Breaking Bad available to stream via the Netflix service. Still, that would suggest you would want 60-70Mbps to view 4K at its best. Step forwards HEVC (High Efficiency Video Coding), aka H.265, which uses around 50% of the bitrate of the video codecs typically used on Blu-ray discs.

There is four times the resolution information compared to 1080p (Full HD) and when you consider a typical Blu-ray will replay at somewhere in the 30-40Mbps range thereвЂ™s a gap that needs to be filled in the compression techniques. This is all well and good but there are questions over just how much benefit 4K can bring when streamed, at what are considered relatively low bitrates. Those kinds of speeds are readily obtainable for many, however, and the network infrastructure can only improve. There are some provisos, of course, the biggest of which is the need for a minimum broadband speed of around 16Mbps and ideally youвЂ™ll want more like 20Mbps to ensure youвЂ™ll not have to endure buffering issues. The UHD TVs released in 2014 by Sony, Samsung and LG all have this capability and Panasonic promises the upcoming AX900 series will also carry the 4K Netflix app, after rather dropping the ball with the AX800/802.
