Sony X77L/X77CL Review (KD-43X77L, KD-43X77CL, KD-50X77L, KD-50X77CL, KD-55X77L, KD-55X77CL, KD-65X77L, KD-65X77CL, KD-75X77L, KD-75X77CL, KD-85X77L, KD-85X77CL)

The Sony X77L has an okay color gamut, but it can’t display the wide range of colors that HDR is intended for.

Unfortunately, like the Hisense A65K, 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.

Ultimately, colors are displayed accurately in most HDR content. Bright scenes, however, look worse, as the TV sacrifices color accuracy in favor of brighter highlights instead.
