The **TCL C79L** (or C7L) is a 55-inch 4K television with a 144 Hz refresh rate and Mini LED backlighting technology. It supports HDR10, HDR10+, Dolby Vision, and HLG formats. The model replaces the C79K and uses TCL's SQD-Mini LED technology, which combines Mini LED backlighting with a new generation of Quantum Dots and a refined filter. The C79L is priced under €1000, currently at €900 at Boulanger, and is available in multiple screen sizes. It is positioned below the more expensive and brighter C89L model. The design of the television is refined, with slim bezels and a central stand, although the plastic used gives it a less premium feel. The C79L has four HDMI ports, two of which are HDMI 2.1, a USB port, an Ethernet port, an optical audio output, but no mini-jack port. It runs on Google TV, featuring a full interface with apps like Netflix, Prime Video, Disney+, YouTube, myCanal, and france.tv. The remote control is black plastic and identical to that of the C79K, while the metal version is reserved for higher-end models. The screen of the C79L is of VA/HVA type with SQD-Mini LED backlighting, offering good contrast, although the blacks are not as deep as on OLED screens. In SDR mode, the calibration gave an average delta E of 3.9 and a color temperature of 7100 K, making the image slightly blue. The average gamma is 2.1, which is a bit low for cinema use in a dark room. The maximum brightness in SDR is 500 cd/m², suitable for use in bright rooms, although the viewing angles remain a weakness, with a 82% loss in brightness at 45 degrees. The C79L supports HDR formats, with a well-followed EOTF curve and a peak brightness of 1822 cd/m² in HDR. The color accuracy in HDR is excellent, with an average delta E of 1.9 and coverage of 97.2% of DCI-P3 and 89% of Rec. 2020. The average reflectance is 24.7%, which is typical for a Mini LED television. The blooming is well managed but still visible, a limitation of Mini LED compared to OLED. The C79L is suitable for gaming with a 144 Hz panel, VRR compatibility, and FreeSync Premium Pro. The input lag is 9.5 ms in 1080p at 60 Hz and 5.1 ms at 120 Hz. The motion blur is 16 ms, which can cause slight blur or ghosting in fast movements. The Game mode has a delta E of 3.9 in SDR and 2.8 in HDR. The audio system of the C79L, tuned by Bang & Olufsen, has a power of 60 W. The sound is adequate for television but lacks bass and spatialization. Adding a soundbar is recommended for optimal audio immersion. The average power consumption of the C79L is 71.5 W, with a consumption of 0.229 kWh for a 2-hour HDR movie. The reparability index is 8.3/10, placing the C79L in the upper range for a mid-range television. The C79L is not without flaws, but it offers a good price-to-performance ratio, good brightness, and solid performance in gaming and HDR. It is rivaled by the C79K, C89L, Hisense U7Q Pro, and other models, each with its own advantages and disadvantages.
