Sub-Type
:
VA
✕
What it is:
Type of display technology used by the TV.
When it matters:
Different technologies have different performance and are suited to different uses
Good value:
IPS maintains good color accuracy at an angle, but has a poor contrast ratio from in front. VA has great picture quality in front, but loses saturation at an angle. OLED maintains good color accuracy at an angle without any of the other issues seen with IPS and VA, as they keep good brightness and contrast at an angle.
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 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.

Score distribution:
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.

Local Dimming
:
No
✕
What it is:
Whether it has a feature that controls the LEDs behind the LCD layer, to match the picture and darkens the dark portion of it.
When it matters:
On LED TVs only. Dark scenes viewed in a dark room.
Backlight
:
Edge
✕
What it is:
Configuration of the lights of the backlight.
When it matters:
Effectiveness of the local dimming.
Good value:
Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs.
There is no local dimming feature on the LeEco Super4 TV. The video is for reference only.

Noticeable difference:

Score distribution:
Mediocre HDR peak brightness. While the measurements are nearly identical to the SDR brightness, HDR content features 1000-4000 cd/m² highlights, so a brighter TV is required to get the best experience. While this TV can't come close to producing the full brightness of those highlights, most of the scene in HDR content is below 200 cd/m², so the brightness of this TV is still passable for watching HDR.

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.

Score distribution:
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.

The motion handling of the Super4 is passable. 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.

Good value:
0 Hz or very high frequencies (> 300 Hz). Frequencies that are multiples of 60Hz are better.
Score distribution:
The Super4 uses PWM at 180Hz to dim the backlight, starting at 99/100 backlight setting. Lowering the setting shortens the duty cycle, while amplitude lowers slightly. Backlight PWM helps clear up motion slightly, but results in duplications following moving objects. We haven't seen any other TVs with a frequency of 180Hz, but it provides good performance at an even multiple of the 60Hz frame rate but high enough not to be noticeable for most people.

The LeEco Super4 TV is not able to display movies without judder under any of the tested frame rates, unfortunately. Movies playing from a 24p source like a Blu-rays player or a native streaming app, and from 60p sources like cable box all suffer from judder. Note that few peoples can notice judder, though, so this is more important for people that are sensitive to it.

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.

Although the TV could accept 4:4:4 color as an input it did not display it properly. This test image shows how the TV was unable to show all the gaps between the lines for some color patterns. However this is only a concern when using the TV as a PC monitor while displaying text.
To play 4K @ 60 Hz the HDMI input in use needs to be set to 4K@60Hz Compatible in the TV's Input settings.
The TV also includes a PC input (VGA with 3.5mm AUX). One of the USB ports is located on the top of the TV for a webcam.

Smart Features
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.

Differences between Sizes and Variants
We tested the 55" (L554UCNN). For the most part, we expect our review to be valid for the 43" (L434UCNN) and 65" (L654UCNN) .
If someone comes across a different type of panel or if their LeEco Super4 doesn't correspond to our review, let us know and we will update the review.

Compared to other TVs
Top left: Vizio M Series 2016 (M70-D3). Bottom left: Samsung KU6300 (UN55KU6300). Middle: LeEco Super4 (L554UCNN ). Top right: Sony X700D (XBR55X700D). 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
50" 55"
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.

Questions & Answers

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.
We are not taking any more questions for this product because we no longer have it in our lab.
