If you measure the color temperatures of different types of display, such as CRT, LCD, or OLED, by using a probe and adjust the xy chroma to the same value, the appearance may be different. This may be caused by the different emission spectrum of each display device. When you adjust the target xy chroma value by adding an offset, you can set to almost the same appearance for different types of display. The following offset values are standard.

Adjusting Bias (OLED Monitor, BVM-HX, PVM-Xxx00)
This software does not adjust the bias on OLED monitors and the BVM-HX/PVM- Xxx00 series monitors. This is because when the gain is adjusted on Sony OLED monitors and the BVM-HX/PVM-Xxx00 series monitors, the monitors automatically correct the internal digital data to correspond with the white balance of the gain based on gamma tracking, even in the dark regions. When the bias is adjusted to improve the accuracy, adjust manually using the following recommended color analyzer which calibrated the matrix.
Recommended color analyzer · Konica Minolta CA-410 (Probe: CA-VP427) · Konica Minolta CA-310 (Probe: CA-PU32,
CA-PU35)
The adjustment procedure is as follows;
1 Perform zero calibration of the probe as required.
2 Input the black signal from the external device to
the monitor.
3 Set the probe to the screen center of the monitor.

4 Checking the brightness display of the color
analyzer, set the brightness of the monitor lower than 0.05 cd/m2 as possible.
5 Set the bias adjustment value of the monitor to the
same color temperature with the gain adjustment value.
6 Set the brightness of the monitor to the original
value which was changed in Step 4.
7 Confirm that there is no change in the chromaticity
and the luminance compared to before the adjustment.
Note
· Performing the manual adjustment in a darkroom is recommended.
· When measuring or adjusting the monitor, set the measurement speeds, synchronization modes, and other settings correctly following the operating instructions of each color analyzer. EXT synchronization mode is recommended. In this case, measure inputting the vertical sync signal of the external device in Step 2 above to the sync input terminal of the probe.
· For details of operating the color analyzer, the matrix calibration, or zero calibration, refer to the operating instructions of each color analyzer.
· Referring to the operating instructions of each monitor, adjust the monitor’s bias following the procedure when adjusting with an external input signal.
· When adjusted with other than the recommended color analyzer, the dark part of the image may get colors or the image may float.
· When the matrix calibration is not performed on the recommended color analyzer, the absolute value of the chromaticity points is not displayed correctly. Before using the recommended color analyzer, measure the target monitor using the high accuracy spectroradiometer, and perform the matrix calibration of the analyzer using the measured value.

Color matching between BVMHX310, BVM-HX3110 and BVMX300
Ver1.02 September, 2023
1. Introduction
After the launch of Sony’s first OLED (Organic Light Emitting Diode) professional master monitor in 2011, it was found that the colors between CRT and OLED displays, even though they were calibrated to have the same xy chromaticity values, did not match based on human visual perception. At that time, an investigation was conducted following research documented in various academic papers on color science and the Sony display group carried out several experiments on color matching in cooperation with color probe providers. It was found that a Judd modified Color Matching Function improved the color matching between CRT and OLED for human visual perception. As a result, Sony has been applying an xy offset calculated by the Judd modified color matching function to Sony professional OLED monitors in order to match the display characteristics of CRT monitors (Refer to Sony White Paper: “Color Matching OLED and CRT”). In 2019, more recent market-driven requirements led Sony to release BVM-HX310, a new master monitor compatible with 4K HDR, this time using a new type of LCD technology. This model has been positioned as the improved successor to BVM-X300, our 4K HDR compatible OLED master monitor released in 2015,that achieves 1000 cd/m2 1 in full screen and includes new 12G-SDI interface, Quad View display mode, and User 3D LUTs support. In 2023, BVM-HX3110, the 4K HDR-compatible master monitor, was released. This monitor has a high peak brightness of up to 4000 cd/m2 1 and high-speed video response capability, and it is also the first Sony monitor for professional use that supports the standard IP interface for SMPTE ST 2110 standard signals. The monitor also has new functions such as WF/VS, HDR/ SDR conversion, and User-LUT signal output, and it has been established as the flagship 4K master monitor model. This model also achieves the same color gamut and spectrum as BVM-HX310 monitors, allowing for seamless coordination between these monitor series.

· 2023: BVM-HX3110 new LCD panel (peak 4000 cd/ m2 1, IP, new functions)
This section describes the techniques for color matching BVM-HX310 or the new model HBV-HX3110 and BVM-X300.
1 Luminance value is the standard value measured at D65 (x, y = 0.3127, 0.329) and not a guaranteed value.
2. Offset value calculated by a Judd modified color matching function for the BVM-HX310
The BVM-HX310 employs a newly developed LCD panel. The LCD panel has high power color-rendering LEDs to realize a wider color gamut resulting in a spectrum characteristic different from that of OLED (Figure 1).
Figure 1. Spectrum of CRT, BVM-X300 and BVM-HX310
Based on the technical background for the development of the Judd offset for the BVM-X300 to match to CRT, Sony also tried to use the offset values calculated by the Judd modified color matching function with the BVM-

HX310. However, the result was that the colors between BVM-HX310 and BVM-X300 did not match human visual perception. The CIE-170 color matching function was also tried, but the result was not acceptable. The results of these experiments indicated that the use of Judd offsets and CIE-170 do not work well when implemented with the BVM-HX310. The most important factor leading to unmatched colors is the variations in individual eye characteristics. It is difficult to assume the use of a single color matching function as a typical value of spectral sensitivity for the human visual system (As described in the white paper “Color Matching Between OLED and CRT”).

3. Recommended offset values for color matching BVM-HX310 and BVM-X300
The white point of D65 for the BVM-HX310, at factory shipment, is adjusted to be the same xy target as used in the BVM-X300. Please, see chart below.

This offset value was determined by color matching experiments between BVM- HX310 and BVM-X300 display devices carried out by Sony’s display group. These experiments showed variations of the best offset value as experienced by each person participating in the tests. Hence, it was decided, at the time, to select and average value of the various results. However, since the release of the BVM-HX310 Sony has received feedback from many customers indicating that the BVM-HX310 appears more reddish than the BVM-X300. It was recently decided to conduct a new series of experiments for evaluation of the color matching between BVM-HX310 and BVM-X300.
