The LG OLED EF9500 4k TV has a very sleek design and excellent overall picture quality, especially in a dark room. Motion handling is excellent, and smart features work very well. It isn't perfect, though. Notably, the input lag is higher than average.
The EF9500 has a flat screen (the only one in LG's OLED lineup). The back of the TV is a white cream color. The borders around the screen are really thin.
With its perfect blacks, the picture quality for movies is really great. The color uniformity could be better, especially with darker shades, but the issues aren't really noticeable with normal content. The TV can be enjoyed from anywhere in the room, and 3D is a nice bonus.
The blacks are really black on this TV, because the pixels self-emit the TV's light.
For reference, we took a video of our local dimming test.
The SDR peak brightness is bellow average and is similar to the HDR peak brightness, and the same comment about the 'ABL' apply. The overall peak brightness is a bit less than what you can achieve while in HDR mode, though.
Like other OLED TVs, it has ABL, which means the maximum luminosity of the screen varies depending on the content of the image. You can see a table of our full measurements here.
In terms of uniformity, this is the worst OLED TV we've seen so far. Even the edges are slightly darker than the rest of the screen. This varies by unit though, so don't look at this number meaning there will be a definite problem, but more as a general indication.
It can maintain its picture quality at an angle without major problems (the colors change slightly, though).
Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.
On a purely black screen, the uniformity is perfect. However, dark grays are not as good (more on this later).
Lower quality content like DVDs or SD channels are displayed without any problems. You might want to turn on 'Noise Reduction' though, to reduce a little bit the noise.
The screen finish has a purple tint, which is a little bit annoying, but not a deal breaker. The screen is glossy, though, so if you have a window directly opposite the TV, your eye will be distracted.
The varying luminosity is not as bad on this OLED as the others we reviewed. With half the screen displaying white, a luminosity of 219.9 cd/m2 is not bad. See here for a table of measurements at different window sizes.
The passive 3D on this TV is great. You don't see the alternating lines the way you do on the 1080p OLED TVs.
The motion performance on the EF9500 is excellent. There is absolutely no motion blur trail following fast objects, and the TV can interpolate 30fps and 60fps content. Most movie sources play without judder.
The TV supports a wide range of resolutions and supports chroma for sharp text. There is a slightly higher input lag time than average. There is a wide range of inputs to plug devices in.
The good news is you don't need to be in any special mode to get lower input lag. You simply need to make sure 'TruMotion' is disabled.
As with all LG TVs, it doesn't support a 120 fps signal. To get chroma 4:4:4, you need to set the input icon to PC. For 4k @ 60Hz @ 4:4:4, you also need to turn on UHD Color.
The sound is pretty good, for a TV. The sound is pretty accurate, has good bass, and gets relatively loud. There also isn't much distortion.
Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.
Good bass extension and loudness. The frequency response is good too, and no pumping is present.
Very good distortion results all-around.
LG's WebOS smart platform is great and very user-friendly. You can control the onscreen cursor with the remote by pointing at the screen. See our full review of WebOS here.
Great all-round TV. Excellent picture quality and motion handling for a range of different content. Unfortunately the screen can't get very bright and fluctuates depending on the content.
Great movie performance. OLED panel provides perfect blacks and great dark scene performance. Picture quality is excellent.
Great for watching TV is an an open room. Excellent picture quality can be enjoyed from all angles. Deals very well with reflections. Unfortunately can't get very bright to overcome ambient light.
Excellent sports performance. Almost perfect motion handling to minimize blur. Uniformity of screen could be better.
Very good video game performance. Excellent picture quality, and motion handling. Unfortunately the input lag is above average for fast-paced games.
HDR looks great. Supports a wide color gamut and brighter highlights. Unfortunately the whole screen can't get bright.
Works well as a PC monitor. Supports a wide range of resolutions at up to 60Hz. Unfortunately there is some temporary image retention after static images.
