Sony BVM-HX310 Calibration Overview
The BVM-HX310 is a 31-inch 4K HDR reference monitor from Sony, designed for professional post-production, mastering, and broadcast applications. It features a dual-layer LCD panel with a 1,000-nit full-screen peak brightness and true 10-bit panel processing, providing accurate color reproduction.
The BVM-HX310 is a high-end choice in the professional display market, ideal for color suites that require a Grade A display for HDR and SDR content.
Below is an overview of the display's performance before and
after professional Sony BVM-HX310 calibration.
The display is ultra-reference grade in SDR after calibration.
Equipment, software and target used in the calibration:
- Calibration software: DCM
- Colorimeter: CR-100
- Spectro: CR-300
- Patch generator: DaVinci Resolve, SDI out
- Calibration target: Rec 709 D65 G2.4 110 nits (SDR)
Native Gamut
This is the native gamut (before calibration) of the Sony BVM-HX310 compared to the Rec 709 color space calibration target. The display's native gamut fully covers the target color space, making it ideal for precise display calibration.
White Point
This is a close-up of the native white point (before calibration) compared to the calibration target of D65. It shows slight deviation from target and a blue tint. The display has CMS controls to manually adjust lower/upper Greyscale, if desired.
RGB Balance
This is the Greyscale RGB balance before calibration, it has a blue tint.
Spectrum Analysis
This is the spectrum of the Sony BVM-HX310 in native gamut for full white, with the red, green and blue primaries
spectral output overlaid to identify color channel issues. The R, G, B color channels match the white
response closely, this is ideal.
Notice the spiky spectral response and narrow peaks, a high-end spectrometer is needed to measure this panel accurately.
Calibration
After display preparation and configuration, the display was then calibrated using the internal CMS controls, which allow very fine adjustments.
Gamut & White Point (post)
Gamut (post calibration) compared to the Rec 709 D65 target - both color space and white point are on target.
RGB Balance (post)
This is the Greyscale RGB balance post-calibration, excellent result.
EOTF: Gamma (post)
This is the gamma and luminance response of the Sony BVM-HX310 after calibration compared to the reference calibration target G2.4. The display now tracks the reference very closely.
Color Error: delta E 2000 (post)
These are the dE 2000 stats post calibration for a 1,100 point stress test validation profile. With an average dE 2000 color error of only 0.21, the Sony BVM-HX310 now performs exceptionally well given that the JND (just noticeable difference) for human vision is set at a dE 2000 value of 2.3.
