TCL 4 Series 2020 TV Review

The TCL 4 Series is an entry-level 4k TV in TCL's 2020 lineup and replaces the TCL 4 Series 2019. It sits above the TCL 3 Series 2020 and below the TCL 5 Series/S535 2020 QLED. Its main competitors are the Toshiba Fire TV 2020, Hisense H6570G, and the Vizio V Series 2020.

The TCL 4 Series is a basic TV with an okay design. It looks a lot like the TCL 4 Series 2019 with a different pattern on the back. It has wide-set feet and the overall build feels cheap.

The wide-set stand is made of plastic, and the TV wobbles a bit. The position of the feet can't be changed to accommodate smaller tables.

Footprint of the 55" TV: 42.6" x 11.7".

The back of the TCL 4 Series is different than the TCL 4 Series 2019. The back panel is made out of metal that feels a bit cheap, and the part where the inputs are is also made from cheap plastic. Sadly, there's no cable management. Note that not all variants have the same VESA mount size.

The borders are relatively thin, especially for an entry-level TV, and shouldn't be distracting.

This TV is somewhat thick, but shouldn't stick out too much when wall-mounted.

The TCL 4 Series has an okay build quality. The overall build feels cheap and there's some wobble. The plastic on the back has some flex and the metal doesn't feel premium.

The TCL 4 Series has an outstanding native contrast ratio. It displays deep blacks, which is expected from a VA panel. Note that contrast may vary between units.

This TV doesn't have a local dimming feature. The video above is provided for reference only.

The SDR peak brightness is poor. It doesn't get bright enough to combat glare in well-lit rooms. Luckily, its brightness is very consistent across different content.

We measured peak brightness after calibration in the 'Movie Picture Mode. If you don't care about image accuracy and want the brightest image possible, we reached 268 cd/m² in the 2% window in the 'Vivid' Picture Mode.

If you wat a budget-friendly TV that gets brighter, check out the Hisense H6510G.

The TCL 4 Series has bad HDR peak brightness. It gets brighter than in SDR, but it's not enough to make highlights stand out.

We measured peak brightness in the 'Dark HDR' Picture Mode with TV Brightness set to 'Brighter'. We got a brighter but less accurate image in the 'Bright HDR' Picture Mode, with everything else at their default settings. We achieved 267 cd/m² in the 10% window.

Our unit of the TCL 4 Series has okay gray uniformity, but this may vary between units. The edges of the screen are noticeably darker and there's dirty screen effect (DSE) in the center, which could be distracting during sports. There's less DSE in near-dark scenes, but there's visible backlight bleed along the edges.

This TV has narrow viewing angles, which is expected from a VA panel. You quickly lose image accuracy as you start to move off-center. If you want a budget-friendly TV with wide viewing angles, look into the LG NANO80.

This TV has alright black uniformity, but this may vary between units. There's a bit of blooming around the center cross and sadly, there's noticeable backlight bleed along the edges. This can be distracting in dark scenes.

The TCL 4 Series has decent reflection handling. It handles a moderate amount of light well but struggles if you place it in a room with a ton of glare.

This TV has excellent out-of-the-box color accuracy, but this may vary between units. There are hardly any inaccuracies with most colors and white balance. Gamma follows the target curve fairly well, but most scenes are too dark. Lastly, the color temperature is a bit warm, giving the image a red/yellow tint.

The accuracy post-calibration is simply incredible. Any remaining color inaccuracies can't be spotted without the aid of a colorimeter, and the color temperature is nearly spot on our 6500K target. Gamma isn't perfect, as some scenes are slightly over-brightened, but this shouldn't be very noticeable.

You can see our recommended settings here.

The TCL 4 Series displays 480p content, such as from DVDs, well. However, it has some trouble properly scaling 4:3 content, so the photo is taken in PC mode, resulting in over-saturated colors compared to other photos.

720p content, such as from a cable box, is upscaled well without any obvious artifacts.

1080p content, like Blu-rays or game consoles, looks almost as good as native 4k content.

There aren't any artifacts with native 4k content as this TV displays it perfectly. It looks more like the TCL 5 Series/S535 2020 QLED than the TCL 4 Series 2019.

This is a 4k TV that doesn't display an 8k input.

Some of the blue pixels appear dimmer but this doesn't result in any picture quality issues.

The TCL 4 Series has an okay color gamut, but it's not considered a wide color gamut for HDR content. It has good coverage of the commonly-used DCI P3 color space, but limited coverage of the wider Rec. 2020.

The EOTF follows the target PQ curve fairly well until it slowly rolls off at its peak brightness, but most scenes are slightly dark. The 'Game' mode EOTF is the exact same.

If you find HDR too dim, set Gamma in the Roku phone app to '1.8'. This results in a slightly brighter image, as you can see in this EOTF.

This TV has a disappointing color gamut. It's mainly limited by its lack of wide color gamut and low peak brightness. However, it displays dark colors well thanks to its high contrast ratio.

The gradient handling is impressive. Most of the banding is visible in the darker shades, especially in the grays and greens. There's a Noise Reduction setting available in the Roku mobile app, but it doesn't improve the gradients at all.

There aren't any signs of image retention, but this may vary between units.

We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.

This TV has a mediocre response time, and it's much slower than the TCL 4 Series 2019. Sadly, there's visible motion blur with most content.

This TV uses Pulse Width Modulation (PWM) to dim its backlight at any level below '18', and the 120Hz flicker may result in some image duplication. The backlight is flicker-free above that level.

There's no optional Black Frame Insertion feature. The TV flickers at 120Hz if you set the Backlight to '18' or below.

This TV doesn't have a motion interpolation feature.

Due to the slow response time, lower-frame rate content doesn't appear to stutter.

This TV automatically removes 24p judder from native apps or Blu-ray players. You don't need to adjust any settings for it to work.

The TCL 4 Series doesn't support any variable refresh rate technology.

This TV has a great low input lag, as long as you're in 'Game' mode. It's lowest at 4k, but it increases significantly at 1080p, which may be too high for reaction-based video games. It has an 'Auto Low Latency Mode' that automatically switches into 'Game' mode when a game from a compatible device is launched, and there isn't a setting to enable it.

It automatically detects when a computer is connected, switching into 'PC' mode. However, the input lag is a bit high in 'PC' mode, and you may notice a delay if you type really fast. If you want a TV with even lower input lag, check out the Hisense R6090G.
