ANY high-speed HDMI cable will work with 2.0a, you do NOT need fancy cables for it.

yeah aware of that just saying bit hard to source a HDMI 2a cable.

For Ultra HD Premium certification the TV at minimum needs the following:

Image Resolution: 38402160

Colour Bit Depth: 10-bit signal

Colour Gamut:
Signal Input: BT.2020 color representation
Display Reproduction: More than 90% of DCI-P3 colours

High Dynamic Range:
SMPTE ST2084 EOTF

Contrast performance:
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.

Thanks Ken appreciate it!  :2thumbs:

What he's saying is there's no such thing as a 2.0a cable, you just need a High Speed (CAT 2) HDMI cable.

There are only two kinds of HDMI cable, Category 1 or "Standard" cables and Category 2 or "High Speed" cables - you want High Speed cables. Version numbers like HDMI 1.4 or HDMI 2.0 refer to the hardware, the cable remains the same.

hi all i have followed this thread with interest and may now be in the market for a new tv. I have a series 5 Samsung 50" plasma which has developed a line going down the screen on the right side...
Do you think this is repairable or am I gonna have to pony up for a new TV soon? (sorry if I'm hijacking this thread with my issue)

With all the talk of UltraHD etc etc how does it actually look - i bought a plasma as I felt the image was warmer than LCD - some LCD images looked a bit 'fake' or too real for me - does the new standard address this?

Each display technology has its own strengths and weaknesses, regardless of the content its rendering. Having said that, one display's image appearing warmer than anothers could be due to the colour temperature setting and images looking fake could be due to the engagement of post processing features - not necessarily the panel type itself.

What I can say though is that the Ultra HD standard's high peak brightness does play to that traditional LCD strength - though a deep black level still remains desireable. At the present moment an LCD coupled with an effective full array local dimming system offers the best Ultra HD performance - though I don't believe these panels are available in South Africa. For SD/HD content you're not going to find better than an OLED - which also does a fine job of Ultra HD, but doesn't have the pop or highlight range of its LCD counterparts

House of Cards should and most newly produced Netflix content bearing in mind you will need a stable line speed of above 20mbs (i read that somewhere so not confirmed by myself)
