Samsung sparks a long-standing 8K standard competition with LG, achieving 8K Association certification for their QLED TV.
1. Samsung QLED TV Achieves 8K Association Certification
In an ongoing battle for 8K standards, Samsung secures 8K Association certification, reigniting the competition with LG for their QLED TV.
This translates to Samsung's range of QLED 8K TVs featuring a minimum screen resolution of 7,680 x 4,320 (double that of UHD TVs). They boast a maximum brightness of 600 nits and support HDMI 2.1 connectivity standard and high-performance HEVC (H.265) video encoding.
While the announcement appears uncontested, behind-the-scenes issues persist. At IFA 2019, LG declared that Samsung's 8K TVs fail to meet true 8K TV standards, despite accurate pixel counts. LG argues that pixels on Samsung's QLED screen lack clear distinction, resulting in lower-than-actual 8K resolution. In contrast, LG claims their 88Z9 OLED and LM99 LCD TV models are sharper and genuinely meet 8K standards. The certification is deemed crucial as it allows Samsung to advertise their 8K TVs endorsed by the 8K Association, guaranteed with a certification logo. Hyogun Lee, Deputy Director of Samsung Display, states, 'Our goal is to help consumers easily identify premium 8K displays compared to others when making purchase decisions.'
Resolution experts don't entirely agree with this test. This measurement overlooks color data, and Samsung states that the construction of their 8K TV is not based on pixel counting but on examining real images. ICDM recently issued a statement 'cooling down' LG's complaints. While Samsung, Panasonic, and Hisense are part of the 8K Association, LG is not. Instead, LG relies on measurements from the International Committee for Display Metrology (ICDM). This group proposes a 'contrast modulation' test, displaying alternating black and white lines with the width of a pixel, then evaluating the effectiveness of these lines. The more distinct the lines, the better the image on an 8K TV.
While debates on standards need not be so intense, this information raises consumer concerns. The majority of users rely on associations like the 8K Association to decide on purchasing 8K TVs, similar to relying on the UHD Alliance for buying 4K TVs. Therefore, it's crucial for these associations to be neutral and act in the consumer's interest, not the manufacturers'.
