Vizio's Reference Series is an extremely capable television, delivering more light output and sheer color ability than almost anything we've had in the lab. The only drawback is that it's a little ahead of its time.

It's too early to test it only for Dolby Vision compatibility or DCI-P3 color (the current/next steps in TV performance), so we ran mostly the same tests as we would on any other TV, including checking it for rec.709 (standard dynamic range/color) gamma, grayscale accuracy, and color production.

I tested the Calibrated Dark, Calibrated, and Vivid picture modes to get the best idea of how the RS65-B2 might look to most viewers. While we intend to eventually test for HDR/Dolby Vision, for the sake of timeliness and scoring parity we currently are only scoring the Reference Series against rec.709/standard performance margins.

Because it tested well out of the box, and uses a very specifically tuned gamma to compensate for FALD's effects on light output, I haven't yet calibrated the RS65-B2 to home theater standard performance.

Color Production

Calibrated Dark picture mode color gamut (uncalibrated)

CalibratedDark-Color-Gamut
Even in the Calibrated Dark picture mode, the RS65-B2 produces slightly more red/green than is necessary for Rec.709/sRGB digital color production. This isn't necessarily a bad thing, but purists will want to hire a calibrator.

Vivid/Rec.2020 color (uncalibrated)

Rec2020-Vivid-Mode-Gamut
In Vivid mode, the TV produces an unprecedented amount of color. While Vivid mode doesn't produce the next-level UHD Rec.2020 color gamut with 100% accuracy, it creates as much or more color than any TV we've had in the lab.

RGB Balance & Grayscale

grayscale
In the Calibrated Dark picture mode, the RS65-B2 tested with excellent grayscale tracking. DeltaE was less than 3 (meaning non-visible error) through the entire grayscale spectrum.
RGB-balance
The RS65-B2's RGB balance results were very impressive. Even without calibration, the TV's grayscale tracking is nearly flawless.

Gamma

gamma
While not entirely flat, the RS65-B2's 2.17 gamma is quite close to the 2.2 standard for average room performance. This is a great out-of-box result, for sure.
