The LeEco Super4 is a 4k LED TV. It has above average picture quality and will be best suited in a darker environment. Unfortunately, the picture quality degrades when viewed from a slight angle. On the upside, both motion and input lag will suit most people's needs and the aluminium frame has great build quality. It is also known by the model codes L434UCNN, L554UCNN and L654UCNN depending on the size.

The design of the Super4 is great, and the TV feels high quality. The wide stand provides good support but requires a very wide table. The build quality is great, and the aluminium frame is nice.

Stand
LeEco Super4 Stand Picture

The L554UCNN has the widest stand of a 55" TV we have seen. The legs support the TV well and are made of aluminum.

Footprint of the 55" TV stand: 10.6" x 47.8"

Back

Wall Mount : Vesa 400x200

The rear of the TV is quite simple. The top half is brushed aluminum, with visible screws holding the back together firmly. At the middle-top of the TV is a USB socket for webcam support. The cables are still easy to access if mounted to a wall.

Borders

The bottom of the TV gets noticeably warm to the touch after it has been on a long time, however this shouldn't be a problem during normal use. The backlight appears to be edge lit from the bottom as that is where it is hottest. The bottom is lined with vents to help keep it cool.

The build quality of the X55 is great. Torx screws on the back allow easily access to the internals if required, and all the machining feels high quality.

Picture Quality

The LeEco Super4 LED TV has an overall average picture quality. The high contrast ratio and the good black uniformity provide good dark room performance, but when set in a very bright room, the average SDR peak brightness will limit the amount of glare the TV can handle. The Super4 won't be the best choice if you have a wide seating area since the viewing angle is terrible. It won't be the best option for sports fans too since the gray uniformity is below average and dirty screen effect is present, even if it can handle fast motion without too much motion blur. The lack of local dimming and the low HDR peak brightness really hurt the HDR performance of this TV, even though it can display a wide color gamut and 10-bit content without banding.

The HDR peak brightness is also a little below average and is essentially the same as the SDR peak brightness. The brightness is the same no matter the size of the bright area shown, so small highlights do not get close to 1000 cd/m2 like some high end TVs with local dimming.

Update 05/08/2017: The peak brightness has been retested with the newest firmware, and remains about the same.

The gray uniformity of this LeEco is average. The top half of the screen is a bit darker than the bottom, and two large dark vertical bands also go from the top to the bottom. The bottom edge of the screen also seems a bit brighter than the rest of the TV.

On the 5% gray uniformity picture, you can see more easily that the bottom edge is brighter than the rest of the screen. You can also see that both right and left sides seem to be more bright, but this is due to the relatively narrow viewing angle of this TV.

The post-calibration color accuracy is excellent, and the calibration process was fast and easy to do. The TV as a 2 points and 10 points white balance calibration. Both were responsive and provided good enough control to make it a simple process. Even though it does not have a more advanced 'Color Management Systems', we ended up with a pretty accurate calibration.

The Super4 can display a wide color gamut, so deep colors in HDR content will be shown properly. However there is a problem with the tone mapping of very bright highly saturated colors, they sometimes clip and become a totally different color. This is shown in this color gamut test done at a higher brightness, the extreme blue point turns orange. Because of this we performed the color gamut testing at a less bright stimulus value of 70 rather than our usual 75, though this should not affect the scores very much relative to other TVs.

Update 05/08/2017: The color gamut has been remeasured with the newest firmware update. The tone mapping has changed slightly (and the clipping error still exists) but the results remain about the same.

This TV has a decent DCI P3 color volume, so HDR colors will be properly represented at various brightness levels. The TV's high contrast ratio allows it to show very dark colors better than most TVs. However this TV has poor Rec 2020 color volume so HDR content that uses the Rec 2020 color space will not have accurate deep color.

Update 05/08/2017: The Super4 has been tested with the newest firmware update and the color volume remains about the same.

The motion handling of the Super4 isn't very good. Fast movement appears quite good due to the fast response time, but the TV doesn't have any options to modify the backlight flicker pattern, and can't play movies without judder. This is not an issue for most people as it generally isn't noticeable. The TV has a 60Hz panel which can interpolate lower frame rate content.

When in game mode the input lag is lower than average and should be good enough for all but the most competitive gamers. All three HDMI ports have the same input lag. The input lag varies by +/- 5 ms every time the TV switches to and from the HDMI input.

Note that when the TV switches to HDR mode it retains the settings from the previous mode it was in, so when gaming in HDR be sure you are in game mode before playing HDR content as you will not be able to switch into game mode once HDR mode is activated.

Smart OS : Android TV

The LeEco Super4 runs Android TV with a skin called eui, Ecosystem User Interface. It comes preinstalled with many popular apps such as Netflix, YouTube and Hulu, and many more apps can be downloaded from the Google Play Store. The TV supports Google Cast so content can be cast to the TV from other devices such as smartphones. The TV has several USB ports that allow content to be played from a flash drive. The included remote is fairly simple but it does include a microphone for voice recognition which works well. The TV supports using a webcam and has a USB port located on top of the TV to make it easier to connect a webcam, though none is included with the TV.

Navigating through the interface is remarkably fast and fluid, with little lag or frame drops; however we did experience some picture glitches during normal use. Most were solved by turning the TV off then back on, but one glitch with the YouTube app required the TV to be factory reset before it was fixed.

Bottom right: Hisense H8C (50H8C).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

While the LeEco Super4 TV isn't a bad TV, it faces fierce competition in its price range that is most often a better choice.

Vizio M Series 2016
50" 55" 60" 65" 70" 80"

The Vizio M Series 2016 has been our top pick for a mid-range TV all year. It provides excellent picture quality in a dark room at a low cost. While it doesn't have as high a native contrast ratio and as wide a color gamut as the LU554CNN, it trumps it by having one of the best local dimming we've tested as well as having excellent response times and input lag. In most cases, it will be a better pick over the Super4.

Samsung KU6300
40" 43" 50" 55" 60" 65" 70"

The Samsung KU6300 performs very similarly to the LeEco Super4. It has a slight advantage for video games but is a bit worse for watching movies in a dark room. It's also more suitable to be used as a PC monitor since it supports chroma 4:4:4.

Sony X700D
49" 55"

The Sony X700D uses a different type of LCD panel (IPS) that has worse picture quality when viewed directly in front but maintains it much better at an angle. This makes it a better pick for those looking to watch TV shows or sports in a wide setting. Both input lag and motion are better than the Super4, so that also makes it a better gaming pick.

Hisense H8C

Provided you can find it, the H8C is a few hundred dollars cheaper than the rest of the competition. Its color gamut is a bit narrower than the LU554CNN so the LeEco is a step above when it comes to picture quality. Smart Features are also quite limited in comparison. It's not very far off everywhere else, though, so it offers equally good value if your budget is tighter.

7.3Mixed Usage
Show Help
What it is General purpose. The TV will be used for a variety of content and usages. Movies at night, TV shows during the day, video games from time to time, etc.
Score components:
Decent TV for mixed usage. It has a very narrow viewing angle but picture quality is above average thanks to its very good contrast ratio. The TV will perform best when used in a darker environment since it's maximum brightness is not very high.
6.8Movies
Show Help
What it is Movies in the dark. The TV will be used for watching movies in a controlled environment, directly in front, in a home theater way. Mostly only high quality content, like Blu-rays, UHD Blu-rays, streaming and a little bit of HDR.
Score components:
Average for watching movies in a dark room. Blacks are deep and uniform, but the TV lacks any local dimming feature to enhance them even further.
7.1TV Shows
Show Help
What it is TV Shows in a bright living room. The TV will be used in to watch TV shows, in a bright room during the day, from multiple viewing positions at different angles. The content watched has an average quality: cable, streaming, SD channels, etc.
Score components:
Passable set for watching TV in a brighter environment. Narrow viewing angles deteriorate the picture quality at even a slight angle. Acceptable amount of reflections, but the TV doesn't get bright enough to counter-act brighter environments.
7.3Sports
Show Help
What it is Sports in a living room. The TV will be used to watch sports during the day, like football or hockey. Usually watched with a group, so from multiple viewing position.
Score components:
Slightly above average for watching sports. Mediocre gray uniformity and poor viewing angle cause even colored fields to look blotchy and change color at the slightest angle change.
7.8Video Games
Show Help
What it is Video games. The TV will be used to play video games, directly in front, in a controlled light environment. Usually fast games, like online FPS, where motion blur and input lag is important.
Score components:
Good TV for gaming. Moderate amount of input lag and little motion blur, so everything feels fluid and snappy.
7.6HDR Movies
Show Help
What it is HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
Score components:
Decent TV for HDR Movies. Because of its low peak brightness, HDR content will not have much of a visual effect. It does have a wide color gamut which is good.
7.8HDR Gaming
Show Help
What it is HDR Gaming. The TV will be used to play HDR video games using consoles that support it or on current generation gaming PCs. Xbox One S, PS4 Pro, GTX 10 series and AMD RX series graphics cards.
Very good for HDR gaming. 4k input lag is not affected by having an HDR input. Peak brightness is limited, however, so the visual effect will not be the most impactful.
4.9PC Monitor
Show Help
What it is PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
Score components:
Poor PC monitor. No chroma 4:4:4 support and narrow viewing angles make this TV a bad choice for a PC monitor.

Hello! I recently purchased this (I am quite impressed with it thus far), can you confirm if your set was utilizing 5.8.050S_1028 firmware?

I'm looking forward to them releasing another firmware version here in April (they stated this in the forums) and they confirmed an Android Nouget update down the line.

At the time of review our Super4 unit was on EUI version 5.8.050S_1028 (same as yours), software version V2401RUS13C058050B10282S. When it receives the major update we will update the review if it changed anything.

Did you guys experience a lot of clouding while the screen was completely black? Also while scenes were really dark, did you guys encounter any problems? I personally own the 65" and have been waiting for this review for a while! Thanks.
We didn't experience a lot of clouding, although there was some. This is visible in our black uniformity test. The Super4 had fairly good black uniformity, as seen here. Black uniformity tends to vary a lot between units, so some Super4 TVs may have worse uniformity than we tested. Some black uniformity problems can be fixed manually, as explained in our black uniformity article in the 'How to Get the Best Results' section.

Is there a way to adjust HDR settings with this TV? I own it and when HDR is active it seems to give me very limited picture options, which is a pain as the HDR blu rays i've watched looked way too dark when I was viewing them. Night scenes in movies looked pure black.
The Super4 doesn't allow for more adjustments in HDR than basic settings like brightness, backlight, and contrast.
