The TCL 4 Series 2019 Roku Smart TV is a decent TV overall. It delivers decent picture quality and displays deep blacks in a dark room thanks to its high native contrast ratio. It can't get very bright, and although it has decent reflection handling it isn't suitable for a bright room. It lacks a wide color gamut, and due to its low HDR peak brightness, it can't deliver HDR content with vivid colors and bright highlights. The response time is fast and the TV displays fast-moving content with very little blur trail. It offers a responsive gaming performance thanks to the low input lag but unfortunately, it lacks any support for advanced gaming features like FreeSync.
The TCL 4 Series 2019 is a decent TV for mixed usage. It has decent picture quality but can't get very bright, so it's more suitable for dim rooms. It has decent motion handling and a fast response time that leaves only a small blur trail behind fast-moving objects. It has a very low input lag, and it's very responsive, making it suitable for gaming or use as a PC monitor.
The TCL 4 Series 2019 is an okay TV for watching movies. It delivers deep blacks in a dark room but lacks a local dimming feature, and black uniformity is just decent. There's no motion interpolation feature and unfortunately, the TV can't remove judder from all sources. On the upside, it upscales 1080p content, like from Blu-rays, really well with no artifacts.
The TCL 4 Series 2019 is an alright TV for watching TV shows. It's more suitable for an average-lit room as it can't get very bright, but it can handle reflections fairly well so a few more lights won't be an issue. You would enjoy your TV shows more if you sit straight in front, as the image loses accuracy when viewed from the side. It has decent gray uniformity and the Roku TV smart interface gives you access to a large number of streaming channels.
The TCL 4 Series 2019 is decent for watching sports. It has a great response time, so fast-moving content has minimal blur trail, and it has decent reflection handling. Unfortunately, it doesn't get bright and it has poor viewing angles, which isn't ideal if you want to watch the big game with a group of friends. There's also visible dirty screen effect in the center, which is distracting during sports.
The TCL 4 Series 2019 is a good TV for playing video games. The input lag is very low and you'll enjoy a responsive gaming experience, while the response time is fast and delivers crisp motion. Unfortunately, there's no support for any advanced gaming features like FreeSync that more serious gamers are usually looking for, but there's an auto low latency mode that is great for casual gaming.
The TCL 4 Series 2019 is mediocre for watching HDR movies. It delivers deep and fairly uniform blacks in a dark room where HDR is meant to be watched, but there's no local dimming support to improve performance. When in HDR, the peak brightness is low and since the TV can't display a wide color gamut either, HDR content doesn't display the vivid colors and the bright highlights it's supposed to.
Decent for HDR games. This is mainly due to the very low input lag that makes it very responsive, and the fast response time that leaves only a small blur trail behind fast-moving content. The HDR performance of the TCL 4 Series 2019 isn't very good as it can't get very bright and it doesn't have a wide color gamut, so it lacks the means to deliver a great HDR picture.
The TCL 4 Series 2019 is a decent TV for use as a PC monitor. It has a very low input lag, and it responds immediately to your actions. It has no risk of permanent burn-in and the response time is fast and leaves only a small blur trail behind a fast-moving object. Unfortunately, the viewing angles are poor, and there are some uniformity issues on the sides of the screen.
The design is simple and in line with other TCL TVs. It's mainly made out of plastic and doesn't have a premium look to it, but its build shouldn't cause many issues. It's a bit different from the TCL S Series/S405 4k 2018.
The stand is made of plastic and supports the TV well. It's almost as wide as the TV and looks like the stand from the TCL S Series/S405 4k 2018, but with a black finish. The legs can't be reversed, and the TV wobbles if nudged.
Footprint of the 43" model stand: 32.2" x 7.3"
The back of the TV is plain. The top part is metal, while the bottom half and the rest of the body are plastic. The TCL 4 Series is available in many sizes and not all of them fit the same VESA mount size. Check here to see which VESA mount size is suitable for each TV size.
There isn't any cable management.
The borders are a bit thicker than most TVs, but won't distract you.
The TV itself isn't very thick and shouldn't stick out when wall-mounted.
Decent build quality. There aren't any gaps or loose ends, and although the TV doesn't have a premium look, we don't expect you to have issues with it.
Excellent contrast ratio, which is expected from a VA panel TV. It's able to produce deep blacks, but unfortunately, there's no local dimming feature to further darken those blacks.
This TV doesn't have a local dimming feature. The video above is for reference only.
Poor SDR peak brightness. It's okay for a moderately-lit room, but it isn't suitable for a bright room as it can't combat glare. On the upside, the brightness remains unchanged no matter the scene, except for small highlights.
We performed our measurements after calibration with the Picture Mode set to ‘Movie.’ Different settings may produce a brighter picture.
You can check our settings page to see how to set the brightness.
This TV has poor HDR peak brightness and can't display bright HDR highlights. Just like in SDR, the brightness remains unchanged no matter the scene. This is almost as bad as the TCL S Series/S405 4k 2018.
We performed our measurements without calibration with the Picture Mode set to ‘dark HDR' and 'brighter.' Different settings may produce a brighter picture.
You can check our settings page to see how to set the HDR settings.
This TV has some uniformity issues as the corners of the screen are darker. There's also visible dirty screen effect in the center, which could be distracting during sports. In near-dark scenes, uniformity is worse as there's backlight bleed along the edges.
Bad viewing angles, which is normal for a VA panel. You quickly lose image accuracy when viewing from the side.
If you want an IPS TV with better viewing angles, check out the LG NANO85.
Decent black uniformity. There's visible backlight bleed at the edges which is only noticeable when you watch a very dark scene in a dark room.
The TCL 4 Series has decent reflection handling. The semi-glossy finish limits indirect reflections, so you shouldn't have issues if you place the TV in a room with lots of small lights. However, if you place it across from a large window, reflections might become distracting.
Disappointing out-of-the-box color accuracy. Most colors are inaccurate and the color temperature is warm, giving the picture a red/yellow tint. The gamma doesn't follow the target well as most scenes are darker than they should be. The colors red and white also clip quite a bit, unless the TV is in 'PC' Picture Mode. Lowering the contrast also helps with this issue, but it worsens the overall picture quality, so we don't recommend doing that.
Excellent color accuracy post-calibration. It's almost impossible to spot any remaining white balance inaccuracies. On the other hand, some color inaccuracies, mainly in the reds and the greens, remain after calibration and some enthusiasts might be able to spot them. Just like with other TCL TVs, calibration is only possible via the mobile app, but you still need to use a colorimeter.

1080p content, like Blu-rays or game consoles, looks great with no obvious issues.
This TV doesn't have a wide color gamut. The true color gamut of the TV is shown by the maximum red, green, and blue in the Rec. 2020 gamut picture. Unfortunately, all other colors in the Rec. 2020 picture and all the DCI P3 colors are under-saturated. We assume that this happens because the TV is prioritizing brightness over color accuracy because it's so dim. These tests were done at 75% brightness stimulus. When we performed the same tests at a dimmer 50% stimulus, the accuracy was much better as can be seen in the following images:
The TV's EOTF is dimmer than the PQ curve, and at about 50% stimulus gray it starts to roll off very early to smooth the transition to the TV's low peak brightness. The same performance is found in 'Game' mode as you can see here.
If you wish to make the HDR brighter, you can set gamma to 1.8 in the phone app. This will result in this EOTF which is a little brighter than before.
Mediocre color volume. It's limited by the lack of a wide color gamut, and it can't display dark, saturated colors.
This TV has impressive gradient handling. A little banding is visible, especially in darker shades of green and gray, but this shouldn't be a problem with real content.
There isn't any temporary image retention on this TV.
We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.
Great response time. There's some overshoot in the darker transitions, but overall, there's minimal blur trail behind fast-moving objects. This is a big improvement over the TCL S Series/S405 4k 2018.
The TV uses pulse-width modulation (PWM) to dim the backlight, but only below 17/100 backlight setting. Backlight PWM dimming results in a 120Hz flicker which might bother some people. This is very different behavior than the TCL S Series/S405 4k 2018, which used PWM dimming throughout the entire range of its backlight levels.
There's no black frame insertion feature to improve the appearance of motion. However, at lower brightness levels, its 120Hz PWM backlight does help somewhat to make motion look clearer but causes duplications.
Unfortunately, this TV can't interpolate lower frame rate motion, which won't please the fans of the 'Soap Opera Effect'.
There's a little stutter due to the fast response time that results in a higher frame hold time of 24p content, like movies.
Unfortunately, this TV can only remove judder from 24p movies when they are played from 24p sources like DVDs or Blu-rays. 24p movies played from 60p/60i sources like cable, satellite boxes, or even through the native apps have some judder.
There's no specific option to remove judder as the TV does it automatically.
