Submenu Setting [Gamma] (When HDR is enabled on the BVME171) Select the gamma when [User CH01] to [User CH30] is selected in the [Color Profile] menu. [CRT BVM]: Gamma curve of the BVM-D or BVM-A series [2.2]: Gamma curve 2.2 [2.4]: Monitor gamma provided by ITU-R BT.1886 [2.6]: Gamma curve 2.6 [2.4(HDR)]: HDR-compatible gamma curve 2.4 [S-LOG3(HDR)]: HDR-compatible log gamma, which is available for the F65 or PMW-F55/F5 CineAlta 4K Camera, etc. [S-LOG2(HDR)]: HDR-compatible log gamma, which is available for the F65 or PMW-F55/F5 CineAlta 4K Camera, etc. [SMPTE ST2084(HDR)]: Gamma curve provided by SMPTE ST2084 [ITU-R BT.2100(HLG)]: Gamma curve provided by ITU-R BT.2100 [S-LOG3(Live HDR)]: HDRcompatible log gamma, which is available for the F65 or PMW-F55/ F5 CineAlta 4K Camera, etc. When [ITU-R BT.2100(HLG)] is selected [HLG System Gamma]: Sets the system gamma of the HLG. Set from 1.000 to 1.500. Notes The gamma is preset to [2.4] that is provided by ITU-R BT.1886 at the factory. With this setting, dark portions may be seen darker than with conventional CRT or LCD monitors. If you wish to obtain the same gamma as that when using a conventional CRT or LCD monitor, set this item to [CRT BVM] or [2.2]. If blocked-up shadows are seen, adjust the brightness for optimum viewing of black portions. The [Gamma] setting is fixed at [2.6] when an XYZ format signal is input. The factory preset black luminance (luminance when no signal is input, or the 0IRE-level signal is input) of the [CRT BVM] setting in the Gamma menu is the same as the black luminance of common CRT monitors. Adjust the brightness (black level) according to the ambient light and the black level of the image to be reproduced. Adjust the contrast (white level) according to the ambient light. Submenu Setting About HDR display The HDR display is a method to faithfully display the brightness of signals in which 100% or more level is defined without compressing the high brightness parts. You can check the high brightness parts that exceed the displayable brightness of the unit by decreasing the contrast. In the HDR display, the cooling fan is forcibly rotated regardless of outside temperature. In the HDR display, the screen saver is forcibly set. [Off] cannot be selected. In the HDR display, [Flicker Free] cannot be selected. [On] is always set for signals of vertical frequency 24 Hz, 25 Hz, 48 Hz, and 50 Hz. [Off] is always set for signals of 30 Hz and 60 Hz. The protective function for the OLED panel activates and inserts the black level in one field according to the input signal. When the signal to display high brightness images on the larger part of the screen is input, blinking may occur due to the protection function. This is not a malfunction. There is no effect on the throughout. Using the unit with the high brightness display for extended periods may cause eyestrain or reduction of eyesight. Be sure to take an occasional break when using it. Follow RECOMMENDATION ITUR BT.1702 "Guidance for the reduction of photosensitive epileptic seizures caused by television" or other guidelines to use. In the HDR display, the display surface may emit heat when high brightness images are output. Do not touch the surface. Do not display static images that contain high brightness display, time codes, markers, or logos for extended periods to reduce the risk of burn-in. Consider applying a display method with low level signals, of 100% or less. When [Format] is set to [3G/HD/ SD-SDI Auto], [HD/SD-SDI Auto], [3G-SDI 444 XYZ 12], [Dual Link 444 XYZ 12], or [HDMI], and the XYZ signal is input, the optimum setting for the XYZ signal is fixed. 43 Adjustment Using the Menus
