The LUM-430M2 is a 4K/UHD monitor with a 42.5" True UHD(3840x2160) resolution and True 10-bit drivers. It supports 12G/6G/3G-SDI inputs and an HDMI 2.0 input. It supports various professional functions including Waveform/Vectorscope, CC-608, 708 and HDR emulation function with HDR EOTFs of PQ, HLG and SLog3.
A true HDR monitor must employ a special display panel with high dynamic range and a wide color gamut, along with being calibrated for PQ and HLG. For example, the LUM-310X (dual layer LCD system) and LUM-310R (LCD with local dimming backlight system) are capable of reproducing a peak luminance of 1,000 nit and 2,000 nit respectively, and a contrast ratio of 1,000,000 : 1; in addition, they cover 99% of the DCI color gamut.
Other monitor utilizing displays with normal luminace range from 0.1nit up to 400nit or high luminance monitor with up to 2000nit with variable black level (0.1 ~ 1.5nit) is defined as 'HDR Emulation monitor' in TVLogic although they have HDR EOTF and related functions. Below is a simple example for your reference.
* True HDR Monitor : HDR Display (~1000nit, 1M CR, DCI gamut) + HDR EOTF & other related function
* HDR Emulation Monitor : Normal Display (~400nit, 1000:1, BT.709 gamut) + HDR EOTF & other related function
And in TVLogic monitors, HDR Emulation function includes the control parameters below;
* Standard Color Mode (HLG, PQ, PQ2)
* Video Range
* Display Luminance *
* HDR EOTF (PQ, HLG) or Camera Logs** (coming soon)
* PQ EETF (On / Off)
* HLG System Gamma (Fixed 1.2 / Auto)
* Color Gamut (BT.709, DCI-P3, BT.2020 and Native mode)
* White Point (D65, D93, DCI)
* Gamut Warning
* Shadow Mode *** (LUM-318G only)
1:1 Pixel Mapping Modes for SD/HD
Displays the original image resolution without scaling to match a certain resolution or an aspect ratio.
Audio Level Meter Display
Displays the level of the embedded sound signal together with the video signal input through the terminal such as SDI or HDMI.
Time Code Display
Displays the Timecode information on the screen.
Waveform Y: Displays the Luma(Y’), Cb, Cr component of the input signal into waveform.
Vector Scope: Displays the color components ‘B-Y’ and ‘R-Y’of the input signals onto the X-Y axis.
