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.
Excellent for watching TV shows in a living room. Great picture quality, even when viewed from the side and deals well with reflections. Unfortunately can't get very bright to compete with a light room.See our TV Shows recommendations
The LG EC9300 OLED TV has a curved screen. The borders are very small, and the stand is stable, with a small footprint.
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 here 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 detailshere.
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).
Standard TV content or DVDs looks good without any major image quality problems.
Upscaled cable and other 720p content looks good and is in line with other 1080p TVs.
Blu-rays and other 1080p looks good without any image quality problems.
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).
That does not mean it is blur free, though. See here 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.
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.
Chroma 4:4:4 is enabled if you set the HDMI input to PC.
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.
