LG has announced a new kind of IPS liquid crystal panel that features an improved color reproduction. The Nano IPS technology will be used for LG’s upcoming high-end displays due in 2018 and will enable professional-grade DCI-P3 color space coverage on consumer models. One of the first monitors to use Nano IPS will be the 32UK950. The 32UK950 will be LG’s new flagship consumer 4K LCD, and will feature the VESA HDR 600 badge along with an integrated Thunderbolt 3 dock.

Nano IPS and HDR 600

LG’s Nano IPS technology will be used on numerous high-end monitors by the company, so it makes sense to examine what manufacturer tells us about it before jumping to the actual product. LG says that it applies nanoparticles to the screen’s LED backlighting to absorb excess light wavelengths and improve intensity, purity as well as the accuracy of the on-screen colors. Controlling spectral output of backlighting is a method generally used to improve IPS LCD panels — quantum dots and Panasonic’s light modulating cells do just that.

Adjusting backlighting spectral output not only enables to improve color reproduction, but also contrast ratio, but this is where LG’s press release gets vague. It never discloses or even mentions static contrast ratio, yet to get the HDR 600 badge (which is what the 32UK950 has), you need to get a black level of 0.1 nits max, which VESA believes is impossible without local dimming. However, neither local dimming, nor pixel-by-pixel control of backlight intensity, are mentioned in the press release.

Wrapping things up, we know for sure that LG’s Nano IPS enables the company to offer an improved color gamut by controlling the LED backlighting. The contrast ratio is something that is expected to be improved on new monitors as well, but LG does not say whether its Nano IPS is responsible for that.

The LG 32UK950

Among the first monitors to feature the Nano IPS technology will be the LG 32UK950. Its 32” panel has a 3840×2160 resolution, can reproduce 1.07 billion colors and cover 98% of the DCI-P3 color space. The HDR 600 badge clearly points to HDR10 processing capabilities along with up to 600 nits brightness, but LG does not disclose any information regarding its LUTs (look-up-tables) for HDR. LG’s current-generation consumer flagship display (the 32UD99-W) can cover 95% of the DCI-P3 gamut, which was a bit lower than 97% DCI-P3 coverage by the 31MU97-B, a professional display with a 4096×2160 resolution. The upcoming 32UK950 will surpass both models when it comes to gamut coverage.

Preliminary Specifications of the LG 32UK950
Panel 32" IPS with Nano IPS technology
Resolution 3840 × 2160
Refresh Rate 60 Hz (?)
Viewing Angles 178°/178° horizontal/vertical
Color Saturation 98% DCI-P3
Display Colors 1.07 billion
3D-LUT supported
Inputs 1 × TB3
DisplayPort 1.2 (TBC)
HDMI 2.0a (TBC)
Audio Integrated speakers

Another major selling point of the LG 32UK950 will be an integrated Thunderbolt 3 connectivity with daisy chaining support (enabling to connect two 4Kp60 displays using a single TB3 port on the host). Apart from TB3 headers, we expect the LG 32UK950 to feature regular DisplayPort and HDMI inputs, a USB 3.0 hub and other essential features.

LG plans to show the 32UK950 at CES trade show early next month. The company does not reveal when it intends to start sales of the new product, or its MSRP.

    On a 5X5 grid of pixels, turning all pixels red except the center pixel which is blue, do you measure the center pixel as blue or purple?

    How many separate shades and colors can you measure on the center pixel when you change the 5X5 grid from white to black to red to green to blue?

    How good or bad is the fidelility of the center pixel to the source when measured?

    Go look up Sampling Theory: for captured (non-synthetic) images "1:1 pixels" means absolutely nothing whatsoever unless your software is broken.

    Likewise, replicating the emission spectra is pointless if you are looking at a screen with human eyes rather than spectrometers.

    When will we ever get a IPS 34 inch 4k monitor or 36 inch? They jump from 32 inch to 43... That's ridiculous! Reply

    LG is releasing a 5k display at 34" with the same nano-IPS tech. Reply
  • Sergiocrz - Saturday, December 23, 2017 - link

    It's not really 5k. It's a odd ultra wide 5120×2160 21.33:9.
    Real 5k is 5120×2880 16:9.

    They're both marketing terms that are bandied about by fools instead of stating the resolution of the product. Reply

    Very close to my ideal monitor, all it needs now is a >60Hz refresh rate and adaptive sync. Reply

    As soon as that comes out you'll have a new spec that is ideal. Reply

    I doubt it. I've been waiting on the same preferred specs for about 5 years now. It seems a much bigger challenge than I would have imagined to put it all together. Reply

    "Very close" would be 1000nits and while the Gamut is okey i struggle to see 4K making a run point until atleast 2021 since the performance gap to 2K is so big for average ~90 FPS gaming, which is where adaptive/Gsync starts to shine.

    As an example: AC Origins - GEFORCE GTX 1080 Ti 11 GB - min 40 / average 45 FPS
