The Hisense A65K has an impressive color gamut, and it displays a wide range of colors with HDR content. Although this TV doesn’t use Quantum Dot technology, it achieves a similar color gamut to mid-range QLED TVs like the TCL Q7/Q750G QLED thanks to the inclusion of a PFS phosphor coating, as confirmed by the TV’s spectral power distribution (SPD). Similar to the Samsung CU8000, this results in a much wider color gamut than similar budget models.
Unfortunately, the tone mapping is poor with content mastered at a high brightness level, so some colors appear off. The results here are with a 75% stimulus corresponding to 1,000 cd/m² content. With dimmer content, the tone mapping is significantly better, as shown with this color gamut measured with a 50% stimulus instead, which corresponds to roughly 92.2 cd/m².
Overall, this means that the majority of HDR content is displayed well, with vivid colors that are displayed properly and accurately. Bright scenes, however, are less accurate, as the TV sacrifices accuracy to reach the brightest highlights it can display.
