LUM-240G : 24” UHD 12G-SDI Single Link Monitor

Whether you are capturing HD, 2K, or UHD the LUM-240G should be part of your workflow. The ability to connect to 3G, 6G and 12Gig links without compromise, provides you with confidence throughout the acquisition and post path.

The LUM-240G is a 24’‘ 4K(3840×2160) monitor with 12G-SDI interface - 4×3G-SDI / 2x6G-SDI & 12G-SDI. The LUM-240G supports various video formats including 12G/ 6G/ 3G/ HD-SDI and HDMI 2.0. The LUM-240G provides wide color gamut up to DCI and includes 3D LUT support and a full feature set.

The LUM series is an integral part of scores of productions. The LUM 240G brings to the discerning user support for the latest 4K capture modes. The key features include wide color gamut, color accuracy, up to 12G SDI support, HDR mode and waveform support.

HDR Emulation

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.
HDR EmulationHDR Emulation
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)

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.

Blue Only / Mono

Red and Green channels are not used and only Blue or Monochrome channel is used to display the screen. This function is used to adjust the color tones (tones and saturation) of the screen using the SMPTE Color Bar. For example, after displaying the Blue channel, adjust the Color (or Saturation) and Tint (or Hue) so that the original Magenta and Cyan are of the same brightness, and the original Gray and Blue are of the same brightness.
blue only

Focus Assist

Assigns a color to the pixels on the boundaries of the image to inform the user to achieve the best focus. With this function, user can easily differentiate the focused area from out-focused area especially when shooting with a shallow depth of field.

H/V Delay

Allows you to check the Blanking area and synchronize signals by displaying the horizontal and vertical intervals in the center of the screen.
H/V Delay


Displays various kinds of aspect ratios on the screen. Wide range of markers and security areas are available with line color and curtain transparency selection. A User Marker is available if any of standard markers fits your requirements.

Time Code Display

Displays the Timecode information on the screen.

Waveform/Vector Scope

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.
