[QUOTE="KenMasters, post: 723868, member: 517"] For Ultra HD Premium certification the TV at minimum needs the following: [b]Image Resolution:[/b] 3840?2160 [b]Colour Bit Depth:[/b] 10-bit signal [b]Colour Gamut:[/b] Signal Input: BT.2020 color representation Display Reproduction: More than 90% of DCI-P3 colours [b]High Dynamic Range:[/b] SMPTE ST2084 EOTF [b]Contrast performance:[/b] More than 1000 nits peak brightness and less than 0.05 nits black level; or More than 540 nits peak brightness and less than 0.0005 nits black level The max refresh rate TVs accept is 60Hz, as the HDTV standard refresh rates are 24Hz/30Hz/50Hz/60Hz (to round off). Panels that advertise higher refresh rates than that are not talking about what they can accept but rather what they output. The reason why they have these higher refresh rates is because of their motion resolution improving systems, "Motionflow", "Auto Motion", "Smooth Motion" etc. They take the existing signal and merge each consecutive frame then insert that interpolated frame between the original frames. The extra "Hz" are where those frames slot in. If you don't make use of those features then you don't benefit from the 120Hz aspect of the panel. LG uses IPS panels which are not known for their contrast, my guess is they fall short of the minimum spec in that regard. LG's OLEDs make certification though (but I do feel the low peak brightness requirement for OLED is something of a concession to the technology). Yes, the JS9500 on paper makes the cut, but I couldn't tell you if everything was properly implemented. [/QUOTE]
