What it is: Type of display technology used by the TV.
When it matters: Different technologies have different performance and are suited to different uses
Good value: IPS maintains good color accuracy at an angle, but has a poor contrast ratio from in front. VA has great picture quality in front, but loses saturation at an angle. OLED maintains good color accuracy at an angle without any of the other issues seen with IPS and VA, as they keep good brightness and contrast at an angle.
:
IPS
Resolution : 4k

The LG 65SK9500 Super UHD TV is a 4k IPS TV with great performance. The picture quality is good, but the TV is better suited to bright rooms with wide seating as blacks appear gray in dark rooms. The image remains accurate when viewed at an angle and the TV has full-array local dimming but it doesn't work very well and results in blooming. It supports a wide color gamut for HDR and also has very good motion handling with a excellent response time.

Design

Score components: Subjectively assigned
LG SK9500 Design Picture
Curved : No

The design of the LG 65SK9500PUA is excellent. It resembles last year's SJ9500. It comes with a metallic curved stand and premium feel. The back is plain and the inputs are accessible from the side if it is wall mounted. The build quality is great and there are no gaps or loose ends. Unfortunately, there is only very basic cable management and the stand prevents you from placing the soundbar directly in front of the TV.

Stand
LG SK9500 Stand Picture

The stand of the TV is metallic, curved and sturdy. It supports the TV from the center, and it will wobble when pushed or if your table shakes.

Footprint of the 65" model: 29.9 " x 11.2"

Back
LG SK9500 Back Picture
Wall Mount : VESA 300x300

The rear of the LG 65SK9500 is very similar to the SK9000. There is no cable management as seen here.

Borders
LG SK9500 Borders Picture
Borders : 0.51" (1.3 cm)

The borders of the TV are thin and look great. Similar to the SK9000, the bezel does not surround the LCD panel. The panel is attached on top of the frame and care should be taken when moving the TV, as it could be damaged if knocked, similar to what happened to our SJ8500.

Thickness
LG SK9500 Thickness Picture
Max Thickness : 2.48" (6.3 cm)

The TV is a little thicker than average but looks thin when viewed from the side due to the smooth angles of the back. It does not stick out when wall mounted.

Temperature

The LG 65SK9500PUA stays relatively cool. There are a few warm spots on the back but not warm enough to cause any issues.

8.5 Build Quality
LG SK9500 Build quality picture

The build quality is great. The TV is solid and there were no obvious gaps or other build issues. Care should be taken when moving the TV as the top is very thin.

7.7

Picture Quality

The LG 65SK9500 has a very good picture quality with decent native contrast ratio. As with most IPS panels, in dark rooms, blacks will look more grayish. It has a full array local dimming that manages to improve contrast a little. It is much brighter than last year's SJ9500, and small highlights are boosted well rather than dimmed like last year. Although it has an IPS panel, the viewing angle is mediocre; it is still better than VA panels, but worse than OLEDs. It also has great reflection handling and thus is a good choice for a variety of room types. The gray uniformity is decent, but there is some dirty screen effect present when watching sports.

6.8 Contrast
What it is: Brightness difference between white and black. This is the main component of picture quality.
When it matters: Always, but especially when watching dark scenes.
Score components:
LG SK9500 Checkerboard Picture
Native Contrast
What it is: Ratio of the white brightness divided by the blacks measured on our checkerboard test pattern with a white target of 100 cd/m².

Contrast with local dimming
What it is: Ratio of the white brightness divided by the blacks measured on our checkerboard test pattern with local dimming turned on (maximum) with a white target of 100 cd/m².
When it matters: Dark scenes in a dark room.
Good value: > 3,000
Noticeable difference: 500
:
2378 : 1

The native contrast ratio on the LG 65SK9500 is decent, but blacks will look more grey than black when viewed in a dark room. This is less noticeable in a brightly lit room.

Contrast improves when local dimming, is enabled but again blacks will fade in dark environments.

5.0 Local Dimming
What it is: The lights behind the LCD layer adapt to the picture displayed, improving the contrast ratio.
When it matters: Dark scenes viewed in a dark room.
Score components: Subjectively assigned
Local Dimming
What it is: Whether it has a feature that controls the LEDs behind the LCD layer, to match the picture and darkens the dark portion of it.
When it matters: On LED TVs only. Dark scenes viewed in a dark room.
:
Yes
Backlight
What it is: Configuration of the lights of the backlight.
When it matters: Effectiveness of the local dimming.
Good value: Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs.
:
Full-Array

The local dimming feature of the LG 65SK9500PUA is not very good. It reacts promptly to moving highlights, and dimming zones do turn on and off on time. The dimming algorithm is not too aggressive and thus clouding around highlights is obvious. It is quite similar to the performance of the SK9000 but slightly smoother.

We recommend setting it initially to High, but if the sudden brightness changes become unpleasant then Medium or Low can be a better choice.

Very good HDR peak brightness. Very small highlights are displayed with good brightness and real scenes are quite bright. This is an improvement from last year's SJ9500 and from SK9000 where highlights were dimmed. However, the brightness is still far from the target 1000 cd/m² to fully appreciate HDR content.

The gray uniformity of the LG 65SK9500PUA is decent and very similar to the SK9000. In brighter scenes, the screen is a little darker on the sides compared to the center. Some dirty screen effect is present when viewing sports. This is not noticeable though on darker scenes.

The black uniformity is mediocre for this LG SK9500. There is clouding all over the screen and only the corners look black. However, things are considerably better when local dimming is enabled. The clouding is only apparent around the center of our test cross.

Great reflection handling on the LG 65SK9500PUA. The semi-gloss finish does diffuse reflections slightly and provides a very similar performance to the SK9000. This should be fine for most rooms, but reflections may be distracting in a very bright room or if sunlight falls directly on the TV.

It is bright enough to overcome most glare and it is our best outdoor TV. However, since it isn't meant for outdoor installation, it is important to properly protect it from the elements with a proper enclosure.

The out-of-the-box color accuracy is very good. The most accurate results were obtained with the Expert (Dark Room) picture mode. Color dE was good, but white balance dE was slightly higher and some people might notice some gray inaccuracy. The color temperature was warmer than our target and, giving everything a slightly red/yellow tint. This was a surprise since it was a change from the out-of-the-box color temperature we measured on the SK9000 which was cold.

Gamma was slightly lower than our target and this might cause some shadows to be darker.

9.4 Post Calibration
What it is: TV's color accuracy after a full calibration with a spectrophotometer.
When it matters: All video on a TV that has been professionally calibrated. This isn't that useful, because most TVs can achieve a pretty good calibration if you spend enough time on them.

LG SK9500 EOTF

The TV is able to display a wide color gamut as it has a very good coverage of the P3 color space.

In the Cinema picture mode the HDR EOTF overshoots the target PQ curve at low stimulus levels, which will cause many shades in HDR scenes to be too bright. If users still find HDR content too dark, setting the TV's Dynamic Contrast setting to Medium raises the EOTF and brightens most HDR scenes. On the other hand, the EOTF in Game mode follows the target PQ curve very well.

The LG SK9500 IPS TV does present some image retention. After the 10 minutes burn-in scene, as we can see on our test picture, the image retention is easily noticeable, but after 2 minutes of recovery, the retention is non-noticeable.

This is result is slightly disappointing and we were not expecting it judging from the results of the SK9000 or the LG SJ9500.

Motion

The LG 65SK9500PUA has very good motion handling. It has an excellent response time, resulting in fluid motion and a short motion trail and low stutter with 24 and 60 fps content. The TV has good black frame insertion, and it can drop flicker frequency to 60Hz, which makes fast paced motion clear when watching sports or playing video games. It has excellent motion interpolation to smooth out low fps content and can display movies without any judder.

:
120 Hz

The LG 65SK9500PUA uses PWM to dim the backlight. This helps clear the motion slightly but also results in duplications following fast-moving objects as seen in the motion blur box photo.

In order to dim the picture the backlight starts flickering at any Backlight setting other than 100. People sensitive to flicker should consider a nearly flicker-free alternative, like the Sony X900F or the LG C8.

9.3 Black Frame Insertion (BFI)
What it is: How effective the TV's flickering capabilities are in making motion look clearer, when flicker is desired.
When it matters: When flicker is desired by the user. Flicker is especially useful to make motion look clearer when viewing 60 fps content (sports, video games) and when using motion interpolation.

The LG 65SK9500 has excellent motion interpolation. Its native 120Hz panel can interpolate lower frame rate content up to 120 fps. It is nearly perfect during slow-moving shots, and it has a pretty conservative algorithm as it stops interpolating as soon as there is too much motion. Very few artifacts were seen during testing.

To activate Motion interpolation, in the TruMotion menu, enable De-judder to interpolate 30Hz content to 60Hz. Enable De-Blur to interpolate 60Hz content to 120Hz.

Sound Quality

What it is: How well and accurately the audio is reproduced.
When it matters: When a good and accurate sound reproduction is needed.
Score components:

The sound quality of the LG SK9500 is above-average. This TV gets quite loud, has a decent amount of body and punch to its bass, and is able to produce clear dialogue. However, it doesn't produce any thump or rumble in the sub-bass region, and its room correction system wasn't able to adjust its sound to our test room. For a better sound, dedicated speakers or a soundbar is recommended.

Dynamic Range Compression
What it is: The amount of difference between the TVs frequency response performance at 70dB SPL and Max dB SPL. Too much compression will result in pumping in the sound.
When it matters: When an accurate and free-of-pumping performance is required at higher volumes
Good value: < 3dB
Noticeable difference: 0.5
:
4.15 dB

The frequency response of the LG 65SK9500 is decent. LFE (low-frequency extension) is at 76Hz, which is above-average. This means that this TV won't produce any thump or rumble, but will have a decent amount of body and punch to its bass. The response above the LFE point is quite well-balanced, which is important for producing clear dialogue. Also, this TV can get quite loud, but will produce some pumping and compression artifacts under maximum load. However, its room correction system (Magic Sound Tuning) wasn't able to remove the modes of our test room around 200Hz.

7.4 Distortion
What it is: Deformation of an output signal compared to its input, usually clipping, harmonic distortion, or inter-modulation distortion caused by non-linear behavior of the sound system.
When it matters: When a clean, pure and transparent reproduction is desired.

The remote is identical to the one found on all high-end LG TVs like the C8 and SK9000. It provides quick access to the most common functions of the TV. It can also be used as a pointer which is the fastest way to navigate the menus and even has a scroll wheel integrated in the d-pad.

The remote also works for voice commands and the TV understands basic commands such as changing inputs, opening YouTube, searching Netflix, etc... But it can not change the settings i.e 'Change backlight to 5' won't work.

It can also be used for setting a sleep timer and for more advanced searches, looking up weather or answering basic searches. Some searches are answered by LG's proprietary ThinQ AI; others were answered by Google Assistant, similar to Sony TVs like the X900F.

LG SK9500 Group Shot Picture
Top left: LG  C8 (OLED55C8PUA). Bottom left: Samsung NU8000(UN55NU8000 ). Middle: LG SK9500 (65SK9500PUA). Top right: LG SK8000 (55SK8000PUA ). Bottom right: Sony X900F (XBR55X900F).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The LG SK9500 offers good performance for most viewing habits and is very well suited for bright rooms. 

LG SK9000
55" 65"

The LG SK9500 is slightly better than the LG SK9000. The LG SK9500 has slightly better response time which is great if you watch sports, and better contrast ratio and black uniformity that produce marginally better blacks while watching movies. The LG SK9500 can get brighter and this is good as you can watch TV shows in a slightly brighter room.

Sony X900F
49" 55" 65" 75" 85"

The Sony X900F is better than the LG SK9500. The Sony X900F is better for watching movies or HDR content right in-front as it has better native contrast ratio, better local dimming along and better black uniformity. The Sony X900F also has a faster response time which is great for watching sports. The LG SK9500 has an IPS panel that gives better viewing angles, and this is good for wide seating arrangements and a lower input lag that makes it very responsive for playing video games. 

Samsung NU8000
49" 55" 65" 75" 82"

If you've got a bright room with wide seating, then the LG SK9500 is a better choice as it has better viewing angles and can handle reflections better and this is important when watching Sports or TV shows. For a dark room, however, with seating directly in-front, the Samsung NU8000 is better. The better contrast ratio and better black uniformity allow it to display deeper blacks in a dark room and thus you will enjoy movies and HDR movies more on the Samsung NU8000. Finally, it supports FreeSync VRR which is great for gamers.

LG C8
55" 65" 77"

The LG C8 is significantly better than the LG SK9500. The LG C8 has perfect blacks which is great if you watch movies or HDR content in a dark room and better viewing angles to accommodate wide seating arrangements. The LG C8 also has better reflections so you can place it a bright room and a faster response time which is great for fast action. On the other hand, the LG SK9500 has a lower input lag for video games and does not have the permanent burn-in risk. 

Samsung The Frame 2018
43" 55" 65"

The LG SK9500 is better than the Samsung Frame 2018, unless your main viewing area is in a dark room. The SK9500 uses an IPS panel, which has much wider viewing angles but a worse native contrast ratio. The SK9500 is brighter, and better suited for a wide, bright room. The Frame uses a VA panel which has a much better contrast ratio and better uniformity. The Frame has some features that should please most gamers, including FreeSync VRR support and auto game mode.

8.0Mixed Usage
What it is General purpose. The TV will be used for a variety of content and usages. Movies at night, TV shows during the day, video games from time to time, etc.
Score components:
Very good mixed usage performance for the LG SK9500. The TV has excellent reflections, and excellent brightness, making a good choice for a variety of usages in bright environments. The gray uniformity is ordinary and that might annoy some sports fans but it has a great response time which is good for games and an ok viewing angle so that it can be placed in moderately wide rooms.
7.4Movies
What it is Movies in the dark. The TV will be used for watching movies in a controlled environment, directly in front, in a home theater way. Mostly only high quality content, like Blu-rays, UHD Blu-rays, streaming and a little bit of HDR.
Score components:
Decent performance of the LG 65SK9500PUA when watching movies. Contrast is ok and blacks cannot get very deep especially in a dark room and the local dimming cannot help improve the situation. This is somewhat expected on IPS panels. Although the black uniformity is not great, it does a great job upscaling content from Blu-ray.
8.2TV Shows
What it is TV Shows in a bright living room. The TV will be used in to watch TV shows, in a bright room during the day, from multiple viewing positions at different angles. The content watched has an average quality: cable, streaming, SD channels, etc.
Score components:
Very good performance when watching TV shows. The TV gets quite bright to overcome glare and has excellent reflection handling, making it a good choice for bright rooms around the house. Viewing angles are ok. It is good at upscaling 720p and cable content so TV shows look great.
8.1Sports
What it is Sports in a living room. The TV will be used to watch sports during the day, like football or hockey. Usually watched with a group, so from multiple viewing position.
The LG 65SK9500 is very good for sports watching. It has the great response time to catch all the action. It handles reflections well and gets bright enough suitable for bright rooms. Also, the viewing angle is not bad so you can watch a game with a few friends, although you might notice some gray uniformity issues on panning shots.
8.6Video Games
What it is Video games. The TV will be used to play video games, directly in front, in a controlled light environment. Usually fast games, like online FPS, where motion blur and input lag is important.
Playing video games on this LG SK9500 is impressive. It has an amazing low input lag and excellent response time, providing an immersive gaming experience. It handles great a variety of input resolutions and although the contrast does not allow it to produce deep blacks, it will make most people happy.
7.4HDR Movies
What it is HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
Score components:
This TV is okay for watching HDR movies. The contrast ratio is not so great and local dimming cannot help the TV display deep blacks in dark environments. Small highlights in HDR content are boosted and shown well. Colors are saturated and accurate, however, some clouding is visible in very dark scenes and that might bother some people.
8.1HDR Gaming
What it is HDR Gaming. The TV will be used to play HDR video games using consoles that support it or on current generation gaming PCs. Xbox One S, PS4 Pro, GTX 10 series and AMD RX series graphics cards.
This TV is impressive for playing HDR games. Colors are accurate and rich, input lag is low and response time is great so that the SK9500 can handle fast action well. There is a variety of inputs including the 4k @ 60Hz + HDR allowing you to have a nice HDR gaming experience.
8.3PC Monitor
What it is PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
Score components:
Very good performance for this LG 65SK9500PUA as a PC monitor. It has excellent low input lag and feels very responsive to mouse movements. It does not have a permanent burn-in risk so one should not be afraid to use it as a monitor. Colors on the edges might look a little washed out when sitting too close to the screen due to average viewing angle performance.
