Samsung emphasized at last week's IFA Global Press conference that none of the current 4k UHD (Ultra High Definition) televisions from the other manufacturers are really future-proof, as none of them are equipped with HDMI 2.0. HDMI 2.0 is still in development, and will make it possible to play UHD video at 50, 60 and even 120 frames per second. The HDMI 1.4a ports on current UHD TVs from Samsung, LG, Toshiba and Sony are able to receive full resolution UHD signals (3840x2160), but at no more than 24 frames per second. This is sufficient voor movies, but no enough for television broadcasts which uses 50 of 60 fps.
Future UHD broadcasts will therefore almost certainly be in 50, 60 or even 100 or 120 frames per second. The UHD TVs that are being sold now will not be compatible with those signals without an upgrade. Samsung says it will offer an upgrade kit with HDMI 2.0 port(s) and the option to retrofit UHD TVs sold this year with HDMI 2.0. Samsung is currently the only manufacturer to offer the possiblity to add hardware modules with new features and/or connectors to existing televisions.
Samsung feels that current UHD TVs aren't future-proof...
... but offers a solution in the shape of the Evolution Kit.
At a 4K press event currently held in LA, Sony suggested that it will offer a solution to make its televisions compatible with the higher framerates when the new HDMI standard is officially unveiled. While none of the Sony reps were able to go on the record, they stongly hinted that consumers that are now buying 55, 65 or 84-inch UHD televisions won't be left out in the cold. That likely means that the input board in the TV could be replaced, but Sony did not want to get ahead of itself.
Sony is hinting that its 55, 65 and 84-inch X9 UHD TVs will be made compatible with HDMI 2.0.
