In exploring the realm of QLED televisions, it’s essential to evaluate models that set the benchmark for color performance.
The 2024 Sony Bravia 9 stands out as a notable option, priced at $2,500. This Mini LED TV incorporates quantum dots and boasts a remarkable 92.35 percent coverage of the DCI-P3 color space, as indicated by RTINGS’ evaluations. Their methodology for assessing color volume involves contrasting a TV’s Rec. 2020 gamut with a model capable of achieving peak brightness levels of 10,000 nits. According to RTINGS, a TV that performs well should exceed 30 percent in this category; the Bravia 9 impressively scores 54.4 percent.
Another competitor in the QLED space is the 2024 Hisense U8, which also employs Mini LED technology. This model offers 96.27 percent DCI-P3 coverage along with a color volume of 51.9 percent, according to RTINGS.
Interestingly, even earlier QLED models exhibit impressive specifications. The Vizio M Series Quantum from 2020, for example, reaches 99.18 percent DCI-P3 coverage and has a 34 percent color volume, reflecting the high standards established by RTINGS’ assessments.
As television manufacturers increasingly highlight quantum dots in their marketing strategies, concerns are arising regarding the authenticity of these claims. While QLED technology generally suggests enhanced color reproduction, there are models in the market that do not live up to this implication.
Guillaume Chansin, associate director of displays and XR at Counterpoint Research, commented on this issue, noting that while QLED should indicate superior color capabilities, some models have been reported to cover less than 90 percent of the DCI-P3 gamut.
Questions About QD Authenticity
Recent developments shed light on the authenticity of certain QLED television claims. Samsung has reported findings on three models from TCL marketed as QLEDs in the United States: the 65Q651G, 65Q681G, and 75Q651G, which are priced at $370, $480, and $550, respectively.
TCL defines QLED technology as a “type of LED/LCD that uses quantum dots to create its display.” According to their description, these quantum dots are nano-sized entities that emit specific colors when illuminated. However, the tests from Samsung raise questions about whether these specific models use cadmium or indium—two essential components typically associated with QD TVs. It’s worth noting that not all QD TVs require both elements; some utilize a mix, contributing to the ongoing dialogue about the true nature of QLED branding.
