The LG SM9500 is a good UHD IPS TV with good picture quality and impressive motion handling. It can get very bright in SDR and has excellent reflection handling, suitable for bright rooms with plenty of light. The contrast ratio is mediocre, as expected from an IPS TV, and the local dimming is bad at improving the dark scene performance in a dark room. It has a wide color gamut, can get very bright in HDR, and can display rich colors and bright highlights. The gray uniformity is mediocre and the noticeable dirty screen effect might bother demanding sports fans, but the viewing angles are good and the image remains accurate when viewed from the side. The SM9500 has a very low input lag, even for the most demanding gamers, and the response time is very fast so that fast motion has only a minimal blur trail.

Our Verdict

7.7 Mixed Usage

The LG 65SM9500 is a good TV for mixed usage. It has excellent reflection handling, can get very bright, and has wide viewing angles, so it's a great choice for large bright rooms where people might be watching from the side. It has a fast response time and motion is crisp to please sports fans. The SM9500 has a very low input lag, great for gaming, but can only deliver decent dark room performance, which will disappoint movie fans.

  • Can get very bright.
  • Image remains accurate at an angle.
  • Very low input lag.
  • Blacks look gray in a dark room.
7.0 Movies

The LG SM9500 is a decent TV for watching movies. Unfortunately, it does not have a high native contrast ratio and its poor black uniformity and the poor local dimming feature don't help much. Therefore, blacks tend to look gray in a dark room and this hurts the overall picture quality in a dark room. It can play movies judder-free from most sources and has a motion interpolation feature to please the soap opera effect fans.

8.2 TV Shows

The LG SM9500 is a great TV for watching TV shows. It has excellent reflection handling and a remarkable SDR brightness so you can easily place it in a very bright room. Also, you can move around when you casually watch your favorite TV show, and the image will remain accurate thanks to the wide viewing angles. Cable content is upscaled well and the TV has motion interpolation for those who enjoy the soap opera effect.

7.8 Sports

The LG 65SM9500PUA is a very good TV for watching sports. It has excellent reflection handling and a very fast response time that only leaves a small blur trail behind fast-moving content. Unfortunately, the gray uniformity is only mediocre and there is some dirty screen effect that might bother demanding sports fans. On the upside, the image remains accurate when viewed from the side so you can invite a group of friends to watch the big game, without worrying who will sit on the side.

8.1 Video Games

This is a great TV for playing video games. It has a remarkably low input lag and feels very responsive. Gamers will also appreciate the fast response time that only leaves a small blur trail in fast-moving content. The SM9500 also supports HDMI Forum VRR for a nearly tear-free gaming experience, but currently, this is only supported on the Xbox One.

7.1 HDR Movies

This is a decent TV for watching HDR movies. The TV has a wide color gamut, can get very bright in HDR and can display a vivid image with bright highlights. HDR content on this TV looks best in a dim room where blacks don't matter as much. When viewed in a dark room, blacks tend to look like gray due to the TV's poor dark room performance.

7.9 HDR Gaming

This is a very good TV for playing HDR games mainly due to its low input lag and fast response time. If you play HDR games in a dim room where deep blacks are not that important, then you will enjoy a great HDR gaming experience. Unfortunately, the low contrast ratio and poor local dimming don't allow for deep blacks in a dark room.

8.4 PC Monitor

This is a great TV for use as a PC monitor. It has a very low input lag and a very fast response time. When you move the mouse, the arrow on the screen responds instantaneously and you won't see much blur. The SM9500 can display proper chroma 4:4:4: so text looks crisp. As an IPS panel, the SM9500 doesn't have the risk of permanent burn-in but there is some temporary image retention.

The LG SM9500 is a 2019 upper mid-range UHD LED TV in LG's NanoCell series. It's the replacement of the LG SK9500 in LG's lineup and its competitors are the Sony X950G, the Vizio P Series Quantum, or other LED IPS TVs like the Sony X850F. Some might also compare it to some higher-end VA panels with the new wide angle technology, like the Samsung Q80R or Sony Z9F.

Curved No

The design of the LG 65SM9500PUA is excellent. The stand is plastic with a silver finish and supports the TV well. However, if you nudge the TV, it wobbles significantly. The back is very plain and made of good quality plastic. Cable management is serviced through the hollow neck of the stand. The entire construction feels solid and looks premium, and you shouldn't have any issues with the build quality of this TV. It's almost identical to LG's flagship Nanocell TV, the 75SM9970PUA, though it has an 8k resolution.


The stand of the TV is plastic and resembles this year's SM8600, but with a metal finish. Although the stand supports the TV well, the TV wobbles a lot if nudged.

Footprint of the 65" TV stand: 32.6" x 12.5".

Wall Mount VESA 300x300

The back of the TV is plain with a horizontal line texture, and it's made of high-quality plastic. Just like the SM8600, the stand's neck is hollow (has a removable cover) and you can guide a few cables through to help with cable management.

Borders 0.47" (1.2 cm)

The borders have a nice metal finish that give the TV a premium look.

Max Thickness 2.56" (6.5 cm)

The LG 65SM9500PUA is a thin TV. It's in the same ballpark as last year's SK9500. It won't stick out much if you wall-mount it.

Build Quality

The build quality is great. There are no gaps or loose ends, but the TV wobbles more than last year's SK9500. You should have no issues with the TV's build quality.

The stand has a plastic cover and in our case, the metallic skeleton was slightly exposed as you can see in the stand picture. We fixed this easily by clipping it back on, and it did not affect our testing in any way.

The LG 65SM9500PUA has a decent contrast ratio. This is expected for an IPS panel TV. When local dimming is enabled, the contrast ratio improves significantly. This is a very similar performance to last year's SK9500. Note that the contrast ratio can vary between individual units.

If you want a TV with deeper blacks, then check out the Samsung Q70R or the Vizio P Series 2018.

Picture Quality
Local Dimming
Local Dimming

The local dimming helps improve the appearance of blacks on the TV. The performance, however, isn't very good and is in the same ballpark as last year's SK9500. When LED Local Dimming is set to 'High', it's very aggressive and there's both a lot of blooming and crushing of highlights at the same time. In dark scenes, this creates a lot of flashing and makes the TV almost unwatchable.

We recommend setting LED Local Dimming to 'Medium' where the blooming and the crushing of highlights is milder.

The LG 65SM9500PUA has excellent SDR peak brightness and can easily fight glare in a bright room, brighter than the LG SK9500.

We measured the peak brightness after calibration, using 'ISF Expert (Dark Room)' Picture Mode, with Backlight set to '100', LED Local Dimming set to 'Medium', and Color Temperature set to 'Warm2'.

If you don't care about image accuracy, you can obtain higher brightness levels. We were able to momentarily reach 1590 nits with the 10% window using the default settings of the 'Vivid' Picture Mode and LED Local Dimming set to 'High'.

The HDR peak brightness is great. The LG SM9500 can get brighter in HDR than last year's SK9500.

We measured the peak brightness before calibration, using 'Cinema' Picture Mode, with Backlight set to '100', LED Local Dimming set to 'Medium', and Color Temperature set to 'Warm2'.

If you don't care about image accuracy, you can obtain higher brightness levels. We were able to reach 1743 nits with the 10% window using the same settings but using LED Local Dimming set to 'High'.

The LG 65SM9500PUA has good viewing angles, as expected for an IPS panel TV. The image remains accurate for wide angles and the TV is a good choice if you have a wide seating arrangement. This performance is better than last year's SK9500 and the SK9000. For even wider viewing angles, check out an OLED TV like the LG C9.

The LG 65SM9500PUA has excellent accuracy with our pre-calibration settings. There are only minimal inaccuracies that are hard to notice without a colorimeter. Some enthusiasts might notice the inaccuracies in the pure white. The gamma does not track the target very well and thus most scenes are a bit brighter than they should be. The color temperature is almost on the target of 6500K. Note that color accuracy can vary between units.

After calibration, the LG 65SM9500 has almost perfect accuracy. The white balance dE is significantly improved, whereas the color dE is better but not by much. The remaining inaccuracies are hard to notice without the aid of a colorimeter. The gamma follows the curve very well and the color temperature is close to the 6500K target.

The TV features an auto-calibration feature which still requires the use of colorimeter.

You can see our recommended settings here.

Picture Quality
480p Input

The LG 65SM9500PUA upscales 480p content, like DVDs, well without any obvious upscaling artifacts. When compared to other TVs, the SM9500 has very similar performance to the SK9500.

Picture Quality
720p Input

720p content, like cable TV, is upscaled well on the LG 65SM9500PUA with no obvious artifacts or softening. This is an almost identical performance to the SK9500.

Picture Quality
1080p Input

Just like last year's SK9500, the upscaling of Blu-rays and 1080p content looks almost as good as native 4k content.

The LG 65SM9500PUA has a great wide color gamut. It is very similar to last year's SK9500. The EOTF is slightly over-brightening some very dark scenes, but, in general, it follows the input stimulus well until it starts a smooth roll off towards the TV's peak brightness. The 'Game' mode EOTF is almost identical as you can see here.

If you find HDR too dim, check out our recommendations here. With these settings, the SM9500 is significantly brighter in HDR, as shown in this EOTF.

The LG 65SM9500PUA has excellent gradient handling. There is minimal banding in some colors, but this is not very noticeable.

The Smooth Gradation feature can help reduce banding, especially when there are large areas of banding. There are cases, however, like the pattern in the photo above, where banding is visible throughout most of the colors and shades and Smooth Gradation can not help. Note that enabling this feature can cause some loss of fine details in some scenes.

The LG 65SM9500PUA has some noticeable image retention that is visible immediately after the 10 minutes burn-in scene. The retention is no longer noticeable after 2 minutes of recovery.

We had measured similar performance on our SK9500 unit, but lower retention levels on our SK9000 and SM8600 units. Temporary Image Retention can be unit specific.

Excellent response time for the LG 65SM9500PUA. It is almost as fast as last year's SK9000 but slightly slower than the SK9500 and this year's SM8600. Nonetheless, the response time is very fast and only a small blur trail can be seen following fast-moving content.

PWM Dimming Frequency
120 Hz

Just like the LG SK9500, this TV uses PWM to dim its backlight. The flicker frequency is 120Hz and this causes some duplications and might bother some people. The backlight flickers at any Backlight setting other than 100.

Black Frame Insertion (BFI)

The LG 65SM9500PUA has an optional black frame insertion feature to help make motion crisper. To enable BFI in the Tru Motion menu, set Motion Pro to 'On'. This changes the backlight flicker to 60Hz but at the same time, you might notice some drop in luminosity.

Some people find 60Hz flicker bothersome.

Motion Interpolation
Motion Interpolation (30 fps)
Motion Interpolation (60 fps)

The LG 65SM9500PUA can interpolate lower frame-rate content up to 120fps. Although the TV continues to interpolate in fairly demanding scenes, when it's displaying very fast scenes, it stops interpolating to avoid creating too many artifacts. When the TV is set to higher levels of motion interpolation, and suddenly stops interpolating due to the very fast scenes, most people will notice a sudden "jerk" in motion. To enable motion interpolation, enable the TruMotion setting.

See here for the settings that control the SM9500's motion interpolation feature.

Frame Hold Time @ 24 fps
28.3 ms
Frame Hold Time @ 60 fps

The LG 65SM9500PUA has some stutter due to the very fast response time. It is, however, not as noticeable as the stutter you will observe in an OLED like the C9. If you find that stutter is bothering you, then motion interpolation can help.

Update 07/12/2019: The SM9500 is now able to remove judder from 60i sources with update 03.60.04. Different settings are required, however, as Trumotion "User" must be enabled with de-judder and de-blur set to "0" as well as Real Cinema "On".

The SM9500 is judder-free from most sources. It can't, however, remove 24p judder from 60i signals. This is similar to what we observed in the SM8600. Last year's SK9500 is able to remove judder from any source.

To remove judder, the Real Cinema option must be enabled in the Picture Option Settings menu.

Update 11/28/2019: Although not officially supported by NVIDIA, the LG SM9500 works with NVIDIA's new G-SYNC compatible mode when connected to a recent NVIDIA graphics card. Unlike officially supported TVs, like the LG C9, this must be manually enabled from the NVIDIA Control Center.

The LG SM9500 has a native refresh rate of 120Hz. The TV doesn't support FreeSync, but we can confirm that it supports HDMI Forum VRR. It's compatible with NVIDIA's G-SYNC, but since it isn't officially supported, you have to enable it manually in the NVIDIA Control Center.
