Samsung South Africa has warned that some of its competitors are marketing their televisions as “4K” or ultra high definition (UHD), but do not comply with overseas certifications for the standard.
“True UHD” televisions offer resolutions of 3840 x 2160 and higher using red, green, and blue subpixels for every pixel.
However, the fake UHD TVs on the market in South Africa add an extra white subpixel to increase the resolution on the spec sheet, but at much lower definition.
Samsung said these fake UHD TVs offer resolutions of 2880 x 2160, which it is calling 3K or “pseudo-UHD”. It added that the panels of these 3K TVs are at least 25% cheaper to make.
“In Germany and America there is a certification process to be able to call your TV UHD or 4K,” said Samsung.
Until similar certifications are in place in South Africa, Samsung said consumers should ensure they know what they are buying when purchasing a 4K TV.
“Testing the TV is quite easy. All you need to do is find white on the TV, take a picture, and zoom in.”
When you zoom in, the subpixels on a true UHD TV will line up in a straight line. The subpixels of an RGBW pseudo-UHD display will appear more scattered.
“Frankly we think this is false marketing. Consumers are being conned,” said Samsung, adding it is going to raise the issue with standards authorities in the country.
