31" Class 17:9 Digital Cinema 4K IPS LED Monitor (31" Diagonal)

  • 31MU97-B

Key Features

  • Digital Cinema 4K Resolution
  • IPS Display with Adobe RGB over 99.5%
  • Total Color Management
  • 10-Bit Color Depth
  • DCP-P3 Digital Cinema Color Standard
10-Bit Color Depth (1 billion colors)

10-Bit Color Depth (1 billion colors)

10-bit color depth that supports over 1-billion colors is 64 times richer than an 8-bit color display, re-creating colors softly and naturally without color banding. Now, all the details are right before you with the richer and wider color range that enables accurate, detailed, and natural-looking images. Also, with smoother transition in gradients, the more shades in between let you work with images in more detail.

IPS Display with Adobe RGB over 99.5%

IPS Display with Adobe RGB over 99.5%

By supporting Adobe RGB over 99.5% on the IPS Display, the 31MU97 minimizes color difference and color loss with the wide color gamut and color temperature that covers both the sRGB and CMYK color range. As a result, one can effortlessly retouch and image photos to create final products with vivid and vibrant colors that VA or other LCD panels cannot deliver.

DCP-P3 Digital Cinema Color Standard

DCP-P3 Digital Cinema Color Standard

Editing on-site footage with the full color expression is possible with the 31MU97’s DCI color standard support which reproduces digital
content color just like what you intended with the preview camera on site. Allows for accurate conditions such as shadow detail, color,
saturation, and brightness for finer editing and overall control in the post production stage.

Digital Cinema 4K Resolution

Digital Cinema 4K Resolution

The 31MU97 delivers 4K (4096 x 2160) resolution across a 31” display, providing crisp images with a significant amount of pixels on screen. 4K(4096 x 2160) resolution displays over four times the resolution of standard 1920 x1080 FHD, and over half a million more pixels than UHD resolution(3840 x 2160) which makes you view even the finest details clearly to carry out intricate work for higher quality output.

Dual Color Space

Dual Color Space

Compare the work done using both color modes simultaneously - half of the screen in one mode and the other half in another - color distortion and maintaining the original resolution are no longer a concern when it comes to output. With Adobe RGB and sRGB side-by-side, you can get an idea of how the final printable will look like with Adobe RGB mode and also can find out how the final output will be on websites with the sRGB mode at once.

Total Color Management

Total Color Management

Through detailed color calibration testing, the 31MU97 maintains the color standard with software calibration and a factory preset, minimizing differences in color space and expressions between the original images, monitor screen, and printed result.

MAXXAUDIO® + 5W Speakers

MAXXAUDIO® + 5W Speakers

With two internal 5W speakers and the MAXXAUDIO® functions,
there is no need for separate high-end monitoring speakers. The 31MU97 which supports MAXXAUDIO® delivers high quality sound with a wide range of vibrant, crisp, and clean high and low sounds while reviewing or editing 4K contents.

Pivot / Height Adjustment

Pivot / Height Adjustment

The 31MU97’s pivot function enables you to not reduce size of photos or drag and scroll the vertically long photos all the way down any more. It also lets you could rotate origin pictures up to 90° depending on the ratio of the work space, giving you the perfect conditions to work under. By activating pivot function on your needs, 31MU97 allows fast and efficient work without any discomfort.

What People Are Saying

Rated 1 out of 5 by from Total junk Bought it and when warranty was expired video board crapped. You did nothing for me so it went to recycle plant. I cannot afford to deal with manufacturers like LG

Rated 5 out of 5 by from LG won't disappoint Have had this tv for 5+ years. It's great, sleek and the picture quality and features are optimal for 2010. Consider this, all advanced features relevant to xbox one are compatible with this lg tv, even though the xbox was released years later. Lg products are competitively equal to other bands, and cheaper. They support all current generation features given the year of the product. I've never had a problem with my LGTV. It's served well and there has not needed to be any maintenance so far. The LG team knows quality as well as reasonable pricing on products.

Rated 4 out of 5 by from Almost Awesome it's now more than 6 months since i purchased the LG tv. it actually is far much better than my previous unit in terms of clarity and im spoilt for choice. i especially like the fact that the navigation is so simple yet precise. also the additional Bluetooth sound function is a plus. i however do have a couple of downside to it. the apps are limited (i wish they introduced KODI for this tv) also the storage is way way to small. i hope they introduce compatible 1tb disks that can be easily replaced, this will assist in strong downloaded movies and series to be viewed later and at leisure. this will also reduce the number of times that the apps have to stop in order for the tv to clear some space otherwise. i would highly recommend this to anyone.

The HDMI ports on this are version 1.4, not 2.0 correct? If so, can a 10 Bit color signal be transferred to this monitor using the unit's HDMI 1.4 port, coming from a Blackmagic Decklink card, which supports 10bit color export over HDMI (2.0)?

What wall mount is compatible with this model? I have purchased a few and none of them are compatible due to the 5x5 indentation on the back of the monitor where the wall mount is supposed to be attached .

Asked by: Jaywass
We appreciate your interest in this monitor. According to the information listed on page 13 of the owner’s manual, begin by installing the wall mount plate, followed by the RW120 mounting bracket, which is a VESA Compliant 100mm x 100mm connection.
