The LG UH9500 is a high end 4k LCD TV offered by LG. It is only available in large sizes, and has pretty good picture quality. When viewed at an angle, the image keeps its contrast and color which is great. Unfortunately the dark room performance is poor due to the low native contrast ratio, and the motion handling could be better.
- Picture remains accurate when viewed at an angle
- WebOS smart platform works well
- Poor dark scene performance
- Peak brightness is below average
The UH9500 has a sleek design, which is very similar to the slightly lower model LG UH8500. The biggest notable difference is the thinness of the top 2/3 of the screen. Unfortunately for a large TV the center stand doesn't provide as much support as the dual supports on the cheaper LG models.
The back looks good, with a brushed metal finish. This is the biggest difference when compared to the slightly bulkier UH8500. The stand also includes a hollow area for cable management. If wall mounted some of the inputs may be difficult to access.
The TV is extremely thin for the top 2/3, and even at the widest point where the inputs are it is thinner than average. This looks very similar to the LG B6.
The UH9500 provides good picture quality in a brighter room, but unfortunately can't get deep blacks to improve dark scene performance. It is limited by the low native contrast ratio. Although it has local dimming, it doesn't work well enough to improve dark scenes. Like most LED TVs it has poor gray uniformity. The wide color gamut and 10 bit panel are very good for HDR content, and when viewed at an angle the picture quality is retained well.
The contrast ratio is below average, which is to be expected from an IPS TV. In a dark room the blacks appear gray, but for a brighter room this is not an issue.
The black uniformity of the UH9500 is good. Like most IPS TVs, some clouding can be seen on our test picture, but luckily it is very hard to notice when watching normal content.
The UH9500 is an edge lit TV that features local dimming. Like most edge lit TVs, the local dimming is not as effective as some other full-array LED TVs. Blooming can be seen in large vertical bands where small highlights are situated.
When set on 'High', the smaller highlights in the video can be seen getting darker and brighter every time a zone gets turned on and off. We recommend that you set it on a lower setting if you notice this behavior when playing video games, or when watching normal TV shows and movies.
The peak brightness is below average. These measurements are consistently lower than the lower end UH8500, which is a bit surprising. Although the whole screen can get quite bright, the local dimming significantly reduces the peak brightness of smaller windows. This test is performed with a HDR10 signal.
The gray uniformity is below average for the LG UH9500. A multitude of vertical bands can be seen throughout the screen. Also, the color on the right side of the screen is also a lot warmer. Dirty screen effect is visible when watching sport or any other media with large panning shots over a uniform color surface.
When viewed at an angle, the contrast decreases a little bit but the colors remain quite accurate. This is about the same result as the LG UH8500 which is good for an LED TV.
Prior to calibration, the results are quite good. The white balance is a little bit off, but this should not be an issue for most people.
Calibration is performed with the 2 and 20 point system on the TV. It works well to remove small errors in the white balance. Even with the color space settings, the blue was undersaturated. You can see our recommended settings here.
The UH9500 supports a wide color gamut, which works well to produce very saturated colors. This is a good result for those who want to watch HDR content.
The LG UH9500 can display a 10 bit gradient pretty well. There are no particular banding or shade problems when analyzing our test picture.
The LG UH9500 do have some image retention, but the retention is present only right after the static scene of the test video. After 2 minutes of recovery, the LED screen is back to normal, without any image retention at all. When compare to others LG high end LED TVs like the UH8500, this is much better and should not be too much a annoyance when watching normal TV content.
The higher end UH9500 has a slightly more glossy screen than the UH8500, but it is still semi-gloss. It should be fine for a room with a few windows. Some faint rainbowing can be seen around direct reflections.
The TV supports passive 3D which means that although there is no noticeable flicker, the number of lines of horizontal resolution is decreased. Due to the size of the TV, this can be noticeable from up close. There is a little bit of crosstalk visible when viewing off-axis.
Although the motion blur is better than average, fast movement isn't as clear as some other TVs. The LG UH8500 which is the model below actually has a shorter trail following moving objects, but this still shouldn't be an issue for most people. The UH9500 has a 120Hz panel which is able to interpolate lower frame rate content, so those who like the soap opera effect will be happy. Movies watched on a bluray player appear smooth.
The motion blur is better than average, but noticeable worse than the slightly lower model LG UH8500. This shouldn't be an issue for most people, however. The backlight uses PWM flicker to dim, and so duplicating images can be seen behind the logo.
Movies playing from DVDs, Blu-rays or from streaming apps play without judder when the 'Real Cinema' option is turned on. Movies playing from 60p/60i sources like cable/satellite/set-up boxes or a computer do have some judder. For most people this is not an issue.
Judder can be removed by setting 'TruMotion' to 'User' and setting 'De-Judder' to a low value. Note that even at a low value, it will introduce a bit of soap opera effect.
The UH9500 has a 120Hz panel, and is able to interpolate lower frame rate content. For those that enjoy the soap opera effect, enable motion interpolation with the 'TruMotion' setting.
The LG UH9500 has good input lag and can accept most of the usual PC resolutions. Traditional gamers will find it responsive enough for fast paced games. HDR gaming is a bit less responsive, but will still be good enough for the casual gamers out there. When used as a PC monitor, it will still be a good choice, since it can easily display the most demanding resolutions with maximum details without any problems.
Input lag is good for SDR content, but more competitive gamers may notice a slightly delay when playing HDR games. For most people, this should not be an issue.
Update 12/08/2016: With the newest firmware update (04.30.19) there has been the addition of a HDR gaming mode. In this mode the HDR input lag is lower, and should be fine for HDR gaming. Note that although the TV accepts a 4k @ 60Hz @ 4:4:4 + HDR signal, it can't accurately display the chroma subsampling in any HDR mode, even with the 'PC' icon selected.
- 20% 1080p @ 60Hz @ 4:4:4
- 20% 1080p @ 120Hz
- 20% 4k @ 30Hz @ 4:4:4
- 20% 4k @ 60Hz
- 20% 4k @ 60Hz @ 4:4:4
To enable chroma subsampling support, change the input icon to 'PC'. It is also necessary to enable 'HDMI ULTRA HD Deep Color' in the 'General' settings menu to allow 4k @ 60Hz @ 4:4:4. Although it has a 120Hz panel, like other LG TVs it is not able to support a 120 fps input.
Average sound performance from the TV speakers. The frequency response is good at lower volumes, but for louder listening has some issues. It also gets loud, which is good. For someone who cares about sound though, a soundbar is an improvement.
Average performance. Frequency response is good at lower volumes. However, under heavier loads compression and pumping will be present. Additionally, this TV does get quite loud and does produce a decent amount of bass, for a TV.
Average harmonic distortion performance. The overall amount of harmonic distortion at 75 is relatively low. The rise in distortion at 85 and maximum volume isn't too much either, and the values remain within decent limits.
The UH9500 features LG's latest iteration of WebOS (3.0). It is very intuitive and easy to use, especially with the included smart remote. It also includes support for popular streaming services such as Netflix and Amazon Video out of the box, with many more applications available from the 'LG Content Store'. It is one of the most stable smart platforms, and is always fast to navigate or load apps.
Even if this is LG's top-end LCD TV, it has ads in the content store.
The included smart remote is the same as provided with other high end LG TVs this year, such as the OLEDs and the UH8500.
Differences between Sizes and Variants
We tested the 65" (65UH9500). For the most part, we expect our review to be valid for the 86" (86UH9500).
If someone comes across a different type of panel or if their LG UH9500 doesn't correspond to our review, let us know and we will update the review.
Compared to other TVs
The LG UH9500 is a good all-round TV, but can be hard to recommend for those looking at the 65" variant due to its similar performance to the cheaper LG UH8500. In some cases, the LG UH8500 actually performs better due to the lower response time and higher peak brightness. For those interested in the 86" variant there is very little competition and it could be a good choice depending on your usage. Keep this in mind when viewing our recommendations below.
The LG UH8500 is the series below, but offers very similar performance. It handles motion a bit better due to the quicker response time, but overall is almost the same TV. For this reason, we recommend the LG UH8500 for the lower price.
The Samsung KS8000 is one of our top recommended TVs of this year, and for good reason. It has much better picture quality from directly in front, due to the higher native contrast ratio and better uniformity. This picture quality degrades rapidly when viewed at an angle, so the LG UH9500 is a better choice for those with wide seating.
The LG B6 uses a different display technology to produce excellent picture quality, from any angle. It has great dark scene performance due to the perfect blacks. Unfortunately this improved performance comes at a higher price, but for anyone with the budget the LG B6 is the way to go.
The Sony X930D is available for about the same price and has excellent picture quality, especially in dark scenes. Unfortunately when viewed at an angle the colors lose accuracy and the contrast drops dramatically. It gets very bright and handles motion very well. As such, it's a better choice for a dark room but if you have wide seating go with the LG UH9500.
