8K TV War As New Association Formed With Brands Taking Sides
Hours out from LG moving to trash Samsung’s 8K TV’s a new 8K TV Association with their own global standards has been announced, missing from the membership line-up is LG who claims that Samsung TV’s “do not comply”.
the new 8K Association has not embraced industry-wide nor do they have Philips, Sony or LG on board with some insiders claiming that Samsung is the brand that has pushed for the new standards which LG for one is not accepting as being the “right standard” for “high quality” 8K TV output.
Back in 2016 Samsung was highlighting the importance of ICDM measurement as a standard for 8K TV’s, this is the same measurement that LG is adopting.
The basic 8K standards set by the new Association claim that 8K TV’s should have a resolution of 7680 x 4320 pixels, input frame rates of 24, 30 and 60 frames per second and peak display luminance of more than 600 units.
The 8K Association also sets HDMI 2.1 as the interface and HEVC as the main codec.
A transparent compliance test to determine if these standards are being lived up to has been established.
LG has a different view of what the 8K standard should be, the Korean Company claims that any 8K standard must meet and surpass the stringent Information Display Measurements Standard (IDMS) for 8K resolution set by the respected International Committee for Display Metrology (ICDM).
Industry experts point out that for a “real 8K” experience, pixels must be easily distinguishable from one another. According to the ICDM, Contrast Modulation (CM), which measures precisely if neighbouring pixels are distinguishable from one another- is the relevant way to measure and describe display resolution.
LG claim that for a TV display to deliver the resolution as indicated by its pixel count, its minimum CM value must exceed 50 percent as well as having a width of 7,680 pixels. Therefore, an 8K TV with a CM value of under 50 percent is not delivering real 8K, even though it may in fact have a width of 7,680 pixels. Tests are run in accordance with industry standards, both LG SIGNATURE OLED 8K and LG NanoCell 8K recorded CM values in the 90 percent range.
Back in 2016 it was Samsung that was highlighting the importance of ICDM measurement as a standard for 8K TV’s. They posted to the Samsung News web site information on what they then described as ‘The new methods for measuring display resolution quality”.
Samsung went on to claim ‘Once the new measurement methods are established, contrast modulation will be the only method to describe display resolution,
giving users a better understanding of display performance”.
