LUM-318G : 31.1” True 4K Monitor with 12G-SDI, HDMI 2.0 and enhanced luminance

The LUM-318G is a 31.1" native 4K resolution(4096×2160)monitor with maximum luminance of 850nit, contrast ratio of 1450:1, wide color gamut and wide viewing angle. Equipped with 4 BNCs (2×12G-SDI + 2×3G-SDI) and HDMI2.0 interface, it supports various video formats upto 4K/60p through single-link 12G-SDI, Quad 3G-SDI and HDMI 2.0. In addition to various professional features such as Waveform monitor and Vectorscope, the LUM-318G provides HDR emulation function with HDR EOTFs of PQ, HLG and SLog3. More camera-specific HDR logs and gamuts will be supported by firmware update.

Blue Only / Mono

blue only

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.

H/V Delay

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.



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

Adjusts the Width /Height display ratio.

Various Scan Modes

Various Scan ModesVarious Scan ModesVarious Scan Modes

Controls the size of the image. Overscan: Extra area around the four edges of the image that may not be seen reliably by the viewer. Underscan: Constrains the size of the image so the monitor shows everything the camera is seeing. 1:1 pixel: Displays the original image resolution without scaling to match a certain resolution or an aspect ratio.

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.

1:1 Pixel Mapping Modes for SD/HD

Displays the original image resolution without scaling to match a certain resolution or an aspect ratio.

HDR Emulation

[Release Notes]
Date : 20.01.06
[LUM-318G [CPU Firmware Update :V004-15 -> 005 / GPU V003-02 -> V0003-09 / FPGA V36 -> V39 ]
1. Debugged the screen issue when input the camera 4K 60Hz signal
2. Improved CC / HDMI Color
3. Debugged showing Grey pattern when using Output Pattern

Date : 19.04.15
[LUM-318G [CPU Firmware Update :V004-15 / GPU V003-02 / FPGA V33 -> V36 ]
1. FPGA: Improved color error of the Ch 3,4 when PQ set with Quad mode.
2. CPU and GPU
- added CC(CC708ANC, CC608ANC, CC608Line21)
- added the OSD position function.
- modified the issue of gamma value which was unchangable.

Date : 18.08.03
[LUM-318G [CPU Firmware Update : V11 -> V18 / GPU V06 -> V09 / FPGA V28 -> V33 ]
1. Improved HDR features
2. Improved by Dolby and Netflix test
- When you set 100nit or 200nit as in SDR or HDR, the nit will be shown as it is.
- When the monitor is set [Local Dimming] ?[Off], the set luminance from 100nit to 1,000nit. If you increase peak luminance, ABL will be automatically activated and it will make backlight level down. After 30 min, backlight will be 1,000nit.
- Highlight was not reproduced well but now it is fixed.
- Peak luminance of Local Dimming (Strong) is 2,000nit as in 4% of white box. More than 2,000nit part of a video will be displayed but ABL will be activated. And, it is going to be 1,000nit.
- Peak luminance of Local Dimming (Soft) is 2,000nit as in 49% of white box.
- Preset value as in Standard is changed.
- Video range setting value is changed. Narrow 100% and Narrow 109% are added in Video Range setting. Preset of HD, UHD, and HLG is changed as 109%.
