LG says Samsung’s 8K TVs are not 8KChristian Fernsby ▼ | September 9, 2019
LG Electronics went on record to claim that Samsung’s 2019 8K TVs do not meet the international standards for 8K resolution and that the company is effectively deceiving consumers.

“We believe Samsung’s 8K TV is not really 8K,” Park Hyoung-sei, executive vice president at LG Electronics’ TV Business Operation Center, said Saturday at a press briefing at IFA 2019.
“Consumers need to know the truth and know what value they are getting for the price they pay.”
LG representatives including Park said tests of commercialized 8K TVs from Samsung, LG and Sony by product-testing and certification bodies Intertek and VDE showed that Samsung’s QLED 8K TV had a contrast modulation level of 12 percent, far below the 50 percent threshold to qualify for the 8K standard.
The company stated LG’s NanoCell 8K TV has 90 percent CM and Sony’s 8K TV has 70 percent contrast modulation.
Contrast modulation, or CM, is the level of distinction between the luminance of white and the luminance of black on a screen. The higher the CM the clearer the distinction between white and black, therefore producing sharper images.
ICDM set the threshold for CM levels for text-displaying screens at 50 percent and image-displaying screens at 25 percent.
In 2012, the ICDM said that contrast modulation is “the best way to describe display resolution” and made it mandatory for companies to report it.
Global tech companies, such as Dolby, Apple, Microsoft, Panasonic, Samsung and LG, had agreed on the guidelines as members of the ICDM.
Therefore, 8K resolution must not only have 33 million pixels - the result of having 7680 by 4320 pixels - but also have a CM of above 50 percent, LG stressed.
Samsung’s TVs had previously abided by this CM level guideline. Samsung supported the importance of CM in its in-house newsroom article dated June 20, 2016.
“You’ll have to ask Samsung what happened (for their 2019 versions),” Park said. “The fall in the Samsung QLED 8K TVs’ CM happened so abruptly and drastically, we only suspect something Samsung did to improve other features, such as improving the viewing angle, to have resulted in negatively affecting the CM rate.”
Samsung QLED 8K TVs still boast ultrahigh definition when seen with human eyes.
LG admitted it is almost impossible to distinguish between 4K and 8K resolutions, but that consumers are entitled to know what product specifications they are paying for. ■
