Resolution 4k

The LG UN6970 is an okay overall 4k TV. It's a variant of the LG UN6950, but it's only available in a 75 inch size and sold exclusively at Best Buy. The picture quality is decent, and it displays 480p through 4k content without any issues. It has an IPS panel with wide viewing angles, but that comes at the cost of its contrast, so blacks appear closer to gray when viewed in the dark. HDR content also doesn't look good on this TV because it fails to display a wide color gamut and has low peak brightness, so highlights don't pop how they're supposed to. Casual gamers should be happy with its low input lag and quick response time, but it lacks many extra gaming features and is limited to a 60Hz panel. The LG WebOS interface is easy-to-use, the menus have smooth navigation, and there are a ton of apps available to download through the app store.

Our Verdict

6.8 Mixed Usage

The LG UN6970 is an okay overall TV. It performs best in wide seating arrangements as it has wide viewing angles. It displays lower-resolution content, such as from cable boxes, without any issues. It's good for gaming thanks to its quick response time and low input lag. However, it doesn't perform well in dark rooms due to its low contrast ratio. Also, it has low peak brightness and doesn't display a wide color gamut for HDR content.

Pros
  • No issues upscaling lower-resolution content.
  • Wide viewing angles.
  • Incredibly low input lag.
Cons
  • Low contrast ratio.
  • Doesn't get bright enough to combat glare.
  • Can't display wide color gamut.
5.9 Movies

The LG UN6970 is disappointing for watching movies. It has an IPS panel with a low contrast ratio and lacks a local dimming feature, so blacks appear gray when viewed in the dark. It also has disappointing black uniformity. Luckily, it upscales 1080p content very well and removes judder from native 24p sources.

Pros
  • No issues upscaling lower-resolution content.
  • Removes 24p judder.
Cons
  • Low contrast ratio.
  • Uniformity issues.
  • No local dimming.
7.4 TV Shows

The LG UN6970 is decent for watching TV shows. It has wide viewing angles so that you can walk around while watching your favorite series without losing image accuracy. It also upscales 720p content, such as from cable boxes, without any issues. Sadly, it's not the best choice to use in well-lit rooms as it only has decent reflection handling and doesn't get bright.

Pros
  • No issues upscaling lower-resolution content.
  • Wide viewing angles.
  • Decent reflection handling.
Cons
  • Uniformity issues.
  • Doesn't get bright enough to combat glare.
7.2 Sports

The LG UN6970 is decent for watching sports. You can easily watch the big game with a large group of friends because it has wide viewing angles. It also has a good response time, but there's still some image duplication with fast-moving content. Unfortunately, it doesn't get bright enough to combat glare and has only decent reflection handling if you want to use it in well-lit rooms.

Pros
  • Wide viewing angles.
  • Decent reflection handling.
  • Good response time.
Cons
  • Uniformity issues.
  • Doesn't get bright enough to combat glare.
  • Blacklight flicker results in image duplication.
7.6 Video Games

The LG UN6970 is good for video gaming. It has a good response time that results in smooth motion and the input lag is incredibly low. However, it has a 60Hz panel and lacks variable refresh rate (VRR) support. Its IPS panel means it has a low contrast ratio and doesn't display deep blacks, but it has wide viewing angles if you want to use it for co-op gaming.

Pros
  • No issues upscaling lower-resolution content.
  • Good response time.
  • Incredibly low input lag.
Cons
  • Low contrast ratio.
  • Blacklight flicker results in image duplication.
5.7 HDR Movies

The LG UN6970 is disappointing for HDR movies. It has a low contrast ratio, disappointing black uniformity, and lacks local dimming, so blacks appear closer to gray when viewed in the dark. It also doesn't get bright enough to make highlights pop in HDR and fails to display a wide color gamut.

Pros
  • Removes 24p judder.
Cons
  • Low contrast ratio.
  • No local dimming.
  • Low HDR peak brightness.
  • Can't display wide color gamut.
6.9 HDR Gaming

The LG UN6970 is okay for HDR gaming, mainly due to its good gaming performance. It has a quick response time and incredibly low input lag. Sadly, HDR content doesn't look all that different from SDR content. It has a low contrast ratio, low peak brightness, can't display a wide color gamut, and lacks local dimming.

Pros
  • Good response time.
  • Incredibly low input lag.
Cons
  • Low contrast ratio.
  • Low HDR peak brightness.
  • Can't display wide color gamut.
8.0 PC Monitor

The LG UN6970 is great to use as a PC monitor. It has wide viewing angles, so the image remains accurate at the sides if you sit too close. Also, it has low input lag, a quick response time, and it displays chroma 4:4:4. However, it doesn't get bright and has only decent reflection handling, so it doesn't perform well in bright rooms.

Pros
  • Wide viewing angles.
  • Decent reflection handling.
  • Incredibly low input lag.
  • Displays chroma 4:4:4.
Cons
  • Doesn't get bright enough to combat glare.
  • Blacklight flicker results in image duplication.

Market Context

The LG UN6970 is an entry-level 4k TV in LG's 2020 lineup. It's a large variant of the LG UN6950 that's sold at Best Buy in the United States for Black Friday. It competes with the Hisense H6510G, Samsung TU6980, and the TCL 4 Series 2020.

Style
Curved No

The LG UN6970 has a decent style. It looks like the LG NANO80, except the feet look similar to those on the LG UN6950. It's a simple TV made out of plastic and metal. The borders are thicker than most TVs in 2020 and may be distracting to some people but shouldn't be an issue for most.

Design
Stand

The stand is almost as wide as the TV itself, and the feet can't be moved inwards to accommodate smaller tables. It holds the TV fairly well, but there's still some wobble, which is expected from a TV of this size.

Footprint of the 75" TV: 60.4" x 13.2".

The back of the LG UN6970 is exactly like the LG NANO80 with smooth metal. Sadly, there's no cable management.

Max Thickness 3.50" (8.9 cm)

The LG UN6970 is somewhat thick, and like the LG NANO80, it may stick out when wall-mounted because the bottom portion bulges a bit. It seems that our unit tilts back slightly, but it isn't noticeable, and your experience may vary.

Build Quality

The LG UN6970 has a decent build quality. It's mainly made out of metal and there aren't any issues with it, but there's nothing special about it. The metal on the back panel flexes a bit, including near the inputs, and the TV wobbles a bit, but it's not too noticeable.

The LG UN6970's contrast ratio isn't bad for an IPS panel, but blacks still appear gray when viewed in the dark. Also, contrast may vary between units. The 50 inch LG UN6950 variant of this TV that we tested has a VA panel and a much better contrast ratio.

The LG UN6970 has mediocre peak brightness. It's extremely consistent across different content, but it's not bright enough to combat glare in well-lit rooms. It gets brighter with the test patterns than the LG UN6950, but it doesn't get as bright in real scenes.

We measured peak brightness in the 'Expert (Dark Room)' Picture Mode with Backlight at its max and all other image processing disabled. If you want a brighter image and don't care about picture quality, we reached 317 cd/m² in the 2% window using the 'HDR Effect' Picture Mode.

The LG UN6970 has disappointing HDR peak brightness. It's similar to the LG UN6950, except it's more consistent between scenes. However, it's not bright enough to make highlights pop how they're supposed to in HDR.

We measured HDR peak brightness in the 'HDR Cinema' Picture Mode with the Color Temperature set to 'Warm 2' and Contrast and Backlight at their max by default. We got the brightest image possible using these settings, as seen in the peak 100% window.

This TV has decent gray uniformity, but this may vary between units. The edges are visibly darker and there's dirty screen effect in the center, which can be distracting during sports. The uniformity is much better in near-dark scenes.

The LG UN6970 has good, wide viewing angles, which is expected from an IPS panel. The image remains accurate when viewing from the side, so it's a good choice for wide seating arrangements. The 50 inch LG UN6950 variant of this TV that we tested has a VA panel and much worse viewing angles.

The LG UN6970 has mediocre out-of-the-box color accuracy. Most colors are only slightly inaccurate, but it has a cold color temperature than results in a blue tint. White balance is off and gamma doesn't follow the target well, so most scenes are too dark, and really bright scenes are too bright. Note that out-of-the-box accuracy may vary between units.

Similar to the LG UN6950, the LG UN6970 has a decent color gamut, but it's not considered a wide color gamut for HDR content. It has very good coverage of the DCI P3 color space used in most content, but it has limited coverage of the wider Rec. 2020.

The EOTF follows the target PQ curve fairly well, but some dark scenes are too bright. The EOTF in 'Game' mode is nearly the same, except the image is slightly less bright.

If you find HDR too dim, set Dynamic Contrast to 'High' and enable Dynamic Tone Mapping in the 'HDR Cinema' Picture Mode. This results in a noticeably brighter image, as you can see in this EOTF.

The LG UN6970 has good gradient handling, similar to the LG UN6950. There's noticeable banding mainly in the darker shades, especially in dark gray. The Smooth Gradation feature doesn't do much on the test pattern but helps smooth out gradients in real content. However, setting it to 'Medium' or 'High' results in a noticeable loss of detail.

The LG UN6970 has an incredibly low input lag as long as you're in 'Game' mode. It's slightly better than the LG UN6950, but it's almost impossible to notice any difference. It has an 'Auto Low Latency Mode' that automatically switches into 'Game' mode when you launch a game from a compatible device. For it to work, simply enable Instant Game Response.

If you want to use this TV as a computer monitor and want the lowest input lag possible, set the input icon to 'PC' and be in 'Game' mode.
