It was replaced by the LG EG9100
The LG 55EC9300 OLED TV provides excellent picture quality and overall performance. The blacks and response time are perfect, but the uniformity of the colors could be improved. There is temporary image retention, but this should not be a problem for most people.
- Perfect blacks
- Perfect motion (although flicker free)
- Great viewing angle (but with a yellow tint)
- Not ideal in a bright room (purple reflections and doesn't get very bright)
- Varying luminosity depending on the scene (ABL)
- Poor dark colors uniformity
- Prone to temporary image retention after displaying static images
The LG EC9300 OLED TV has a curved screen. The borders are very small, and the stand is stable, with a small footprint.

With its perfect blacks, the LG 55EC9300 provides really good picture quality. You will need to play with the settings a little bit though, because by default it crushes shadows a bit too much. The uniformity is very good, and the picture quality remains good even when viewed at an angle. It supports a wide color gamut but unfortunately does not get very bright.
It is also only a 1080p TV, but given the 55" size, that's only a big deal if you sit relatively close.
Our luminance meter (Minolta LS-100) gave us a perfect 0.000 cd/m2 reading on a checkboard pattern, resulting in an infinite contrast ratio.
Of course, it doesn't have a backlight, so there is no local dimming. But for the sake of comparison, we ran our local dimming test. As expected, there is no blooming.
When HDR arrives, one of the elements that will distinguish the performance of TVs is how bright it can make the highlights of a picture. Like plasma TVs, OLEDs have an automatic brightness limiter (ABL). The less whites the TV needs to display, the brighter those whites will be. We measured the luminosity of a 2% white window at 342.7 cd/m2, which isn't particularly impressive. Due to the ABL, a white fullscreen is even less, at only a maximum luminosity of 94.6 cd/m2. See the Q&A section of our review for a full table of the luminosity of different window sizes.
The darker the color, the worse the uniformity gets. It is also constantly changing. More details in the Q&A section of the review.
The viewing angle is great, better than every LCD TV. We measured a drop of half the luminosity at 82 °, which is excellent. However, there is a yellow tint at an angle, something that our current test doesn't factor in.
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.
The blacks are also perfectly uniform. Note that this is only for a pure black. The uniformity isn't perfect for solid colors (more on this later).
You can increase the color gamut by changing 'Color Gamut'.
The glossy finish is very aggressive. It is actually very good at cutting the ambient reflections, but gives everything a purple tint. The curve of the TV also zooms in on the reflections. If you have a window directly behind you (facing the TV), it is really bad.
The maximum brightness of the screen varies depending on the scene you are watching, due to the ABL. At a 50% window, the luminosity is lower than what you would get from an LED TV.
Its passive 3D has no crosstalk issue, but it comes at the cost of half the vertical resolution. This is a bit more noticeable than on LED passive 3D TVs, due to the smaller pixel sizes (see pixel close up picture at the end of the review).
The EC9300 deals with motion very well. It is able to interpolate 30Hz and 60Hz content. The response time is almost perfect, resulting in very clear images with no following trail. Movies from a blu-ray player play smoothly.
That does not mean it is blur free, though. See the Q&A for more details.
It handles a direct 24 fps input without judder, which is good for movies outputted via a Blu-ray player. For 24p via 60i or 60p though, it couldn't consistently do the reverse 3:2 pulldown. Of course, if you enable 'TruMotion' it removes the judder, but at the cost of introducing the soap opera effect.
The input lag is quite good, and should not be an issue for most people. It is a 1080p TV and so doesn't support higher resolutions. It does have a wide range of inputs.
Under game mode, the input lag is 47.5 ms. If you label the HDMI input to PC, you can further reduce it to 40.7 ms.
Update 07/25/2016 We've received a report that the input lag is now 29.6 ms after the firmware update 04.01.00. We don't have that TV anymore to confirm this unfortunately.
- 20% 1080p @ 60Hz @ 4:4:4
- 20% 1080p @ 120Hz
- 20% 4k @ 30Hz @ 4:4:4
- 20% 4k @ 60Hz
- 20% 4k @ 60Hz @ 4:4:4
Chroma 4:4:4 is enabled if you set the HDMI input to PC.
The LG 55EC9300 has better sound than the average TV. It doesn't get loud and doesn't have a lot of bass, but at least the distortion is almost nonexistent.
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 frequency response at all levels and no pumping seems to be present either. However it doesn't produce a lot of bass.
Very good distortion results at all levels, but the TV doesn't get loud.
WebOS is a great smart TV platform and it is very easy to use. The remote can control the on-screen pointer, but it doesn't have a dedicated number pad.
