Samsung is set to introduce two new UHD televisions, each with a resolution of 3,840 x 2,160 pixels. The new 55in and 65in UE55F9000 and UE65F9000 models will be positioned next to the 85in model that's already out. The new TVs will cost £4,300 and £6,020, respectively. The UE55F9000 is already listed for pre-order at Curry's for £4,299. They will compete with the 55in KD-55X9005 and 65in KD-65X9005 UHD TVs from Sony. Sony's 55in model is slightly more affordable, while the 65in model is at the same price point. They're still not cheap, but at least no longer as ridiculously priced as the 85in model (which is more expensive than the average annual income of many people).
The problem with current UHD televisions is that they don't support HDMI 2.0, since the standard is still being developed. Because of that, it's not possible to view 3D footage in UHD resolution, and the framerate is limited to 30 frames per second. Future UHD broadcast with 50 or 60 frames per second won't look entirely smooth, in other words.
Samsung has created an interim solution by using separate modules. The new 55in and 65in TVs are equipped with a separate inputbox. It contains most of the processor power, the tuners and the HDMI ports. The box connects to the rest of the TV by means of a cable.
As soon as HDMI 2.0 has been finalised, Samsung promises to release a box with the new connectors, and when you hook that up to your F9000 TV you will be able to enjoy 3D UHD and 50 or 60 fps.
It's not the same as the Evolution Kits for the 7000 and 8000 series TVs - that's a module that's attached to the back of those TVs. For the F9000, the entire input box will be replaced. You can read the rest of Samsung F9000 'upgradable' UHD TV preview on Hardware.info.
