The Variable Refresh Rate (VRR). For gamers, the TCL C7K supports a refresh rate of up to 144 Hz, but consoles typically work up to 120 Hz via HDMI 2.1. The great differential is the VRR (Variable Refresh Rate), which synchronizes the TV’s rhythm with that of the console to make the image smoother and prevent issues like ‘tearing’—the famous image breakage.
In the games I tested on the C7K, Street Fighter 6 and Spider-Man 2 stood out with 120 Hz. For instance, Street Fighter ran at 120 frames per second, reducing command latency. Spider-Man 2 offers two modes—one with a free FPS and another running at 40 FPS but ‘tripled’ to appear smoother. In this mode, the TV uses its 120 Hz to display each image three times, creating a smoother gameplay even with fewer actual frames per second.
The VRR, combined with high frame rates, is essential to unlock the maximum potential that next-gen consoles like PlayStation 5 and Xbox Series have to offer.
Points of attention
Limited built-in speakers. Despite having a 6.2.2 channel system, 60W of power, and a partnership with the audio giant Bang & Olufsen, the C7K’s speakers are only decent. The sound is loud and clear, but the bass is almost non-existent. For those who enjoy listening to music, movies, and series, a soundbar is highly recommended.
Screen uniformity and residual blooming. The Mini-LED panel still lags behind OLED in this aspect. This is evident in the presence of light leakage in high-contrast scenes—when light from bright areas ‘leaks’ into dark areas, causing unwanted spots or glares, such as in white subtitles.
