The LG UN6950 is a basic entry-level 4k TV with limited features. It's sold in North America and appears to be only available at Walmart. The 50 inch TV we reviewed has a VA panel, while most of the other sizes have IPS panels, so they have better viewing angles and worse contrast. Our unit has an impressive contrast ratio to produce deep blacks, but the TV doesn't have a local dimming feature. It doesn't perform very well in bright environments because it doesn't get bright and struggles to handle reflections in rooms with direct sunlight. This TV should please casual gamers, as it has a quick response time and really low input lag. Sadly, HDR content doesn't look good because it can't display a wide color gamut and doesn't get bright enough to truly bring out highlights.
The LG UN6950 is an overall okay TV. The 50 inch TV's VA panel has an impressive contrast ratio, so the TV displays deep blacks. It's good for gaming because of its quick response time and low input lag, but the backlight's flicker may cause duplication in motion. Sadly, it lacks many extra features like local dimming and variable refresh rate (VRR) technology. It doesn't get bright enough to combat glare and its reflection handling is just decent. Lastly, it has narrow viewing angles, so it isn't suggested for watching TV with a large group of people.
The LG UN6950 is alright for watching movies. Its VA panel displays deep blacks, but it lacks a local dimming feature and it has uniformity issues. It upscales lower-resolution content well and removes judder from 24p sources, like native apps. Even though it has a fast response time, lower frame rate content doesn't stutter much.
The LG UN6950 is decent for watching TV shows. It performs best in dim rooms because it doesn't get very bright and reflections from direct sunlight may be too distracting. Unfortunately, the 50 inch model has narrow viewing angles, so it isn't suggested for wide seating arrangements. It upscales 720p and 1080p content, like from cable boxes or apps, without any issues.
The LG UN6950 is reasonable for watching sports. Fast-moving content doesn't have much motion blur because it has a quick response time, but its 120Hz flicker leads to duplication in motion. It's not a good choice for bright rooms because it doesn't get very bright and its reflection handling isn't the best. It isn't suggested for wide seating arrangements either because it has narrow viewing angles.
Good for video games. The LG UN6950 has a quick response time, but its 120Hz flicker may lead to duplication in motion with 60Hz games. The lack of VRR support may not please serious gamers, but the incredibly low input lag is ideal for casual gamers. It's good for dark-room gaming because it has an impressive contrast ratio, but it doesn't have a local dimming feature.
The LG UN6950 is mediocre for watching HDR movies. This TV can't display a wide color gamut for HDR content and it doesn't get very bright in that mode, so HDR content doesn't look all that different from SDR content. Even though it has an impressive contrast ratio, it lacks a local dimming feature and it has some uniformity issues.
The LG UN6950 is decent for HDR gaming, mainly due to its good gaming performance. It has a really low input lag and quick response time, but it doesn't have any extra gaming features like VRR support. Even though this TV supports HDR10, HDR content doesn't look all that different from SDR content because it can't display a wide color gamut and doesn't get bright enough to truly bring out highlights.
The LG UN6950 is a decent choice if you want to use it as a PC monitor. It displays proper chroma 4:4:4, which is important for reading text, and it has a really low input lag. Sadly, it has narrow viewing angles, so the edges of the screen may appear darker if you sit too close. It also doesn't perform the best in bright rooms because it doesn't get bright and reflections in really bright rooms may be too distracting.
The stand is almost as wide as the TV, so you may need a large table, depending on which size you get. The legs wobble quite a bit.
Footprint of the 50" model: 41" x 9.2"
The LG 50UN6950ZUF has thick borders that may be distracting for some.
The LG 50UN6950ZUF is thicker than the LG UM6900 but still shouldn't stick out too much if you wall-mount it.
Okay build quality. The LG 50UN6950ZUF is built completely with plastic that doesn't feel all that premium. The back panel flexes near where you would attach the VESA mount. The stand doesn't feel solid and wobbles fairly easily.
The LG 50UN6950 has an impressive contrast ratio, which is expected from a VA panel. Blacks are deep when viewed in the dark. Take note that the contrast ratio may vary between units.
Note: Only the 50 and 60 inch models of this TV have a VA panel. The 43, 55, 65, and 75 inch models have an IPS panel, and we expect them to have a worse contrast ratio.
The LG UN6950 has mediocre peak brightness. It doesn't get bright enough to combat glare in bright environments, but luckily, its brightness remains very consistent across different content.
We measured the brightness after calibration in the 'Expert (Dark Room)' Picture Mode with the Backlight set to 'Max' and all other image processing disabled. If you want the brightest picture possible, we were able to get 366 cd/m² in the 10% peak window using the 'Vivid' Picture Mode, and with TruMotion off.
This TV doesn't have a local dimming feature. The video above is provided for reference only.
Disappointing HDR peak brightness. This TV doesn't get bright enough to truly bring out highlights in HDR. Its brightness is consistent across different content, except really small highlights aren't as bright.
We measured the brightness in the 'HDR Cinema' Picture Mode with the Color Temperature set to 'Warm 2'.
If you want the brightest picture possible, we were able to get 395 cd/m² in the 10% peak window test in the 'HDR Vivid' Picture Mode with Dynamic Contrast set to 'High' and Dynamic Tone Mapping on.
Decent gray uniformity. The edges of the screen are noticeably darker, and there are dark vertical bands throughout the screen. There's also visible dirty screen effect in the center, which could be distracting during sports. In near-dark scenes, the uniformity is better, except there's backlight bleed along the edges.
Gray uniformity may vary between units.
Black uniformity is alright. There's backlight bleed along the edges, but there's not too much clouding around the center cross. This may vary between units.
If you want a similar TV with better black uniformity, check out the Toshiba Fire TV 2020.
The LG 50UN6950ZUF has bad viewing angles, which is normal for a VA panel. The image quickly loses accuracy when moving off-center, so this isn't suggested for wide seating arrangements.
Note: Only the 50 and 60 inch models of this TV have a VA panel. The 43, 55, 65, and 75 inch models have an IPS panel, and we expect them to have better viewing angles, similar to the LG UN7300.
The LG UN6950 has decent reflection handling, but it's much worse than the LG UN7300 in really bright rooms. If you have direct sunlight on the screen, reflections may become too distracting.
There's a beam of light appearing down the middle of the photo, which is caused by the tube light in our room.
Disappointing out-of-the-box color accuracy. Most colors are inaccurate and the white balance is off, which affects the way shades of gray are displayed. Gamma doesn't follow the target at all, so most scenes appear brighter than they should. Color temperature is also warm, so the image has a red/yellow tint to it. If you want a similar TV with better out-of-the-box color accuracy, check out the LG UN7000.
Out-of-the-box color accuracy may vary between units.
After calibration, the LG UN6950 has amazing color accuracy. Most colors are extremely accurate, except for red, which is still a bit inaccurate. Gamma follows the target almost perfectly and the color temperature is extremely close to the 6500K target.

Upscaling of 720p content such as cable TV looks good and there are no visible artifacts.
The LG 50UN6950ZUF displays native 4k content perfectly without any problems.
The LG 50UN6950ZUF has a decent color gamut, but it can't display a wide color gamut for HDR content. It has good coverage of the commonly-used DCI P3 color space, but it has very limited coverage of the Rec. 2020 color space.
The EOTF follows the target fairly well until it rolls off at its peak brightness, but most scenes are brighter than they should be. The 'Game' mode EOTF is very similar, as you can see here.
If you find HDR too dim, set the Dynamic Contrast to 'High' and turn Dynamic Tone Mapping on. The image is a bit brighter, as you can see in this EOTF.
This TV has a disappointing color volume, mainly because of its lack of a wide color gamut. It doesn't display colors at a wide range of luminance levels well.
Good gradient handling. There's visible banding in the darker shades and there's some banding in the lighter grays. Enabling Smooth Gradiation smooths out real content a bit, but it introduces strange horizontal banding in the test pattern.
There are no signs of temporary image retention on the LG UN6950, even immediately after displaying our static test image for 10 minutes. Temporary image retention may vary between units.
Note: The horizontal dark band in the center is likely caused by the flicker of the TV and the shutter of the camera not matching up. The TV doesn't actually display a dark band.
We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.
Good response time. Fast-moving content in most scenes has minimal motion blur, but there's significant overshoot in dark scenes, which can lead to motion artifacts. The TV's 120Hz flicker also creates a duplication in motion.
The LG 50UN6950 uses Pulse Width Modulation (PWM) to dim its backlight. It always flickers at 120Hz. If you prefer a TV with a flicker-free backlight, check out the Sony X750H.
This TV doesn't have a Black Frame Insertion feature.
This TV can interpolate content up to 60fps, but there's duplication in motion due to the backlight's 120Hz flicker. The motion interpolation feature works well and smooths motion out, but in busy scenes, there are visible artifacts.

Despite having a good response time, lower-frame rate content doesn't stutter much on this TV.
