TCL 1 Series/D100
TV REVIEW
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 TCL D100 is a basic 1080p TV with decent picture quality. It lacks many of the features found in higher end TVs to improve the picture quality further, and has sub-par motion performance. Unlike most other TCL TVs, it almost completely lacks a smart platform.

Design
Score components:
Subjectively assigned
Score distribution:
The TCL D100 is a very basic looking TV, and certainly won't be the centerpiece of any room. It has a wide plastic stand, with a similar design to other TCL TVs such as the S305. It appears a bit thick when viewed from the side, but the HDMI inputs are fairly easy to access.
Maximum Temperature

Score distribution:
The TCL D100 1080p LED TV has a decent picture quality. Dark room performance is very good since it has a great contrast ratio and an excellent black uniformity which in turn makes for very good dark scenes with deep blacks. When set in a bright room, the D100 doesn't perform as well since it can't get that bright and it can't deal that well with reflections. The gray uniformity is okay and dirty screen effect not too strong, which is good new for sports fans out there. The viewing angle is disappointing and unfortunately, it relegates the best picture quality to narrow zone right in from of the TV.

Contrast
What it is:
Brightness difference between white and black. This is the main component of picture quality.
When it matters:
Always, but especially when watching dark scenes.

Contrast with local dimming
:
N/A
What it is:
Ratio of the white brightness divided by the blacks measured on our checkerboard test pattern with local dimming turned on (maximum) with a white target of 100 cd/m².
When it matters:
Dark scenes in a dark room.
Good value:
> 3,000
Noticeable difference:
500
Score distribution:
The TCL D100 has a great contrast ratio and with a contrast ratio hovering around 4300:1, this means it can produce blacks that are very deep. When set in a dark room, the D100 can reproduce dark scenes very well.
0
Local Dimming
What it is:
The lights behind the LCD layer adapt to the picture displayed, improving the contrast ratio.
When it matters:
Dark scenes viewed in a dark room.
Score components:
Subjectively assigned
Score distribution:
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
:
Direct
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.
The TCL D100 does not have a local dimming feature. The video is for reference only.

Score distribution:
Okay SDR peak brightness. The brightness remains constant no matter the content shown, which is good (the real scene brightness is measured near the edge of the screen where it's not as bright). Unfortunately this brightness, while good enough for a dim room, isn't good enough for a very bright room. However few budget TVs like this are any brighter, in fact the D100 is brighter than the pricier TCL S305 and S405.

Score distribution:
The gray uniformity is average for the D100. Looking at our 50% gray uniformity picture, you can clearly see that most of the uniformity issues are from the corners being too dark. The center is more even though and although dirty screen effect is present at some level, is not too distracting.
Looking at the 5% gray test picture, we see that the edges are a bit brighter, but this is not very apparent in dark scenes with normal content.

Score distribution:
Poor viewing angle, not as good as TVs with an IPS panel but better than most TVs with a VA panel. Blacks turn grey and colors shift when viewed from a moderate angle, with brightness dropping to half soon after. This TV is not a good fit for a room where people often view the TV from the side.

Score distribution:
The D100 is decent at handling reflections. It has a semi-gloss finish which slightly reduces the intensity of direct reflections by diffusing them across the screen. It is okay for an average room, but for a room with a few wide windows or lots of light this may be an issue.

What it is:
The color temperature is a measure of the color of light. A colder color temperature (7000K) will look bluer and a warmer color temperature (4000K) will look yellower/redder. 6500K is the standard color temperature use in the TV and film industry as program, film, and photography directors usually work on monitors calibrated on the 6500k color temperature and do their color correction base on what they see on those monitors.

What it is:
The best value for the TV's color temperature setting. The setting name differs between brands; for some it's "Color Temperature", for others its "White Point".
When it matters:
All content on screen
Gamma Setting
:
N/A
What it is:
The best value for the TV's gamma setting; the setting name differs between TV brands.
When it matters:
Shadows, accurate grayscale performance.
Out of the box, TCL D100 accuracy is sub-standard and the white balance, even when set to the color temperature 'Warm', the final temperature color is cooler than what is usually preferred. With a white balance dE of 5.95, this level of inaccuracy is high enough that most people could notice it. As a result of the bad white balance, since the gamma and white balance are closely related, the gamma is also off our 2.2 target.
Unfortunately, the color dE is not better. With a dE 4.90, the color accuracy is high enough so that almost anybody could notice that the color are wrong. Most of the issues start with the fact that the white point is off target and the same drift can be seen for all the other color, resulting in a high dE for all of them.
4.5
Post Calibration
What it is:
TV's color accuracy after a full calibration with a spectrophotometer.
When it matters:
All video on a TV that has been professionally calibrated. This isn't that useful, because most TVs can achieve a pretty good calibration if you spend enough time on them.

720p Input
What it is:
Quality of a 720p input.
When it matters:

Score components:
Subjectively assigned
Score distribution:
720p content such as cable looks good (but a bit soft) once upscaled. The native resolution isn't a multiple of 720p, so the TV applies a zoom and it isn't possible to fit to the screen. This also causes some added softness, so it may be worth increasing the sharpness slightly for low quality content. An example of sharpness 10 can be seen here.

If the TV faces a risk of developing permanent burn-in after being expose, for a long period of time, to static images.
When it matters:
When watching TV shows with static logos or banners (news or sports channels), when playing video games with a HUD (head up display), and when using a TV as a PC monitors.

Motion
Score components:
- 53% Response Time
- 11% Flicker-Free
- 3% Black Frame Insertion (BFI)
- 5% Motion Interpolation
- 12% Stutter
- 11% 24p Judder
- 5% Variable Refresh Rate
Score distribution:
The motion handling of the D100 is lacking. The response time is good, resulting in a short trail of blur following fast moving objects and the response has some overshoot, resulting in a pale trail following dark objects moving against a lighter background. The TV flickers at 120 Hz to dim, so motion isn't as smooth as some other TVs but most people won't notice it. This TV is unable to play movies at 24p without judder, even directly from a 24p source such as a movie played on a DVD player. The D100 cannot interpolate lower frame rate content and is therefore unable to produce any soap opera effect.

Score distribution:
The TV uses PWM at 120Hz to dim the backlight, starting at 100/100 backlight setting. Lowering the setting shortens the duty cycle, while amplitude remains constant. Backlight PWM helps clear up motion slightly, but results in duplications following moving objects.

Auto Low Latency Mode (ALLM)
:
No
What it is:
Whether a source (such as a game console) can request the TV switch into a low latency mode (such as game mode).
When it matters:
Console gaming; both PS4 and Xbox One S/X support ALLM.
Low input lag, though not as low as many TVs with a 'Game Mode' option like the TCL S405. As the TV does not have a game mode and shows 4:4:4 color in any picture mode, the input lag is always the same.
One flaw is that the TV's input lag cycles by ~6 ms: it starts at 27.9 ms, increases to 33.5 ms then loops back to 27.9 ms. This isn't really a concern though, and should only be noticeable by very competitive gamers who are sensitive to input lag. Most TVs do not show this cycling, they maintain a constant input lag (though some take a minute or so to settle, like Samsung TVs).
Another interesting detail is that the TV refreshes the screen from the bottom to the top, so the bottom has the lowest input lag. This is the opposite of most TVs because they refresh from the top to the bottom. We always measure input lag at the center of the screen so this doesn't affect our measurements.

The TV's remote is rather large, but unfortunately it doesn't make very effective use of that size. Its buttons aren't as wide as on similarly sized remotes, and so aren't as easy to press; and there's a lot of wasted space between the buttons, so there's fewer buttons than on comparable remotes like the large Sony remotes. Also the LG basic remotes are smaller yet have more buttons than the TCL remote, because they make more effective use of space.

Amazon.com
Mediocre TV for a mixed usage. 1080p TV with decent picture quality when viewed from directly in front, but degrades at an angle. Lacks features found on higher end TVs such as local dimming, and unlike most TCL TVs doesn't have a smart platform.
Poor for watching movies in a dark room. Great native contrast so blacks appear dark, but lacks local dimming to improve this further. Picture is inaccurate and doesn't support high quality 4k content.
Decent TV for casual viewing in a wide room. Image degrades rapidly when viewed at an angle. Won't be able to overcome reflections in a bright room, and lacks a smart interface.
Okay for watching sports. Picture quality is decent, and response time is good so only a short trail follows fast moving objects.
Decent for gamers. Doesn't support higher 4k resolutions of new consoles, but has low input lag. Picture quality is decent and response time is good so only a short trail follows fast action.
Doesn't support HDR. Can't get bright, doesn't have a wide color gamut and doesn't support 4k content.
No support for HDR gaming. Doesn't support HDR features such as wide color gamut or high peak brightness.
Okay choice for PC monitor. Doesn't support resolutions higher than 1080p but picture quality is decent. Narrow viewing angle so the sides of the screen lose accuracy when viewed from up close. Feels responsive with low input lag and fairly good motion blur.
