History and Development
Early Generation (2010‑2013)
The 42LCD was first introduced in 2010 as part of a broader strategy to diversify the mid‑range television portfolio. Initial models were powered by a standard T-CPU processor and featured a 1‑channel 20 W speaker system. During this period, the panel technology was primarily IPS, offering wide viewing angles but lower contrast compared to VA panels.
Mid‑Generation Improvements (2014‑2016)
Between 2014 and 2016, revisions to the 42LCD incorporated updated back‑light systems, moving from CCFL to LED. This transition reduced power consumption and allowed for a slimmer chassis. Connectivity options were expanded to include a second HDMI input, a component input, and the introduction of a 2.5‑GHz Wi‑Fi module. At the same time, manufacturers began offering the 42LCD with a 20 W stereo speaker system that included a small subwoofer to compensate for the limited low‑frequency response of the built‑in speakers.
Current Generation (2017‑Present)
The latest generation of the 42LCD, launched in 2018, introduced HDR10 support, 10‑bit colour processing, and an upgraded 2.4‑GHz dual‑band Wi‑Fi module. These changes were accompanied by an updated user interface that is compatible with a growing range of streaming services. The design has also shifted towards a more minimalistic aesthetic, with a thinner bezel that occupies less than 3 mm around the perimeter of the display. The device has been made available in a curved variant, offering a 120° viewing angle, as well as a flat‑panel version that preserves the original rectangular shape.
Design and Build
Case and Material Quality
The housing of the 42LCD is constructed from a high‑grade ABS plastic that has been coated to resist scratches and dents. The frame around the display is reinforced with a lightweight metal alloy that provides additional structural stability. Despite this, some users have reported that the rear panel is susceptible to deformation when subjected to prolonged pressure, such as placing a heavy object on top of the unit.
Dimensions and Weight
The flat‑panel variant of the 42LCD measures 96.3 cm in width, 57.0 cm in height, and 5.5 cm in depth. Its curved counterpart is 5.7 cm thick at the center of the curve, extending to 5.3 cm at the edges. The overall weight of the flat model is 9.2 kg, while the curved version weighs 9.6 kg, which is comparable to other 42‑inch televisions in the same price bracket.
Stand and Mounting Options
The included stand is adjustable on three axes, allowing for tilt, swivel, and height modifications. The maximum tilt angle is 20°, and the height range spans from 45 cm to 65 cm. For wall mounting, the 42LCD supports VESA patterns of 200 × 200 mm and 400 × 400 mm. The wall-mounting bracket that comes in the box is compatible with standard 4‑pin mounting hardware, though it is recommended to use a high‑load bracket for wall mounts exceeding 8 kg.
Display Technology
Panel Type
The base model utilizes an IPS panel, offering a typical viewing angle of 178°. In contrast, the curved variant employs a VA panel, delivering a more substantial contrast ratio. The IPS panel delivers colour accuracy in the range of 70 % of the DCI‑P3 gamut, whereas the VA panel reaches approximately 75 % coverage.
Resolution and Colour Depth
All variants support a native resolution of 1920 × 1080 pixels, with a pixel density of 53 ppi. Colour depth has been upgraded to 10‑bit, enabling 1,024 discrete shades per colour channel. This results in a theoretical maximum of 1.07 billion colours, an improvement over the standard 8‑bit 16.7 million colour range found in earlier models.
Refresh Rate and Motion Handling
The 42LCD operates at a fixed 60 Hz refresh rate, which is adequate for standard definition and full‑HD content. Motion smoothing options include a 2‑step frame interpolation system that can upscale frame rates to 120 Hz for high‑motion gaming or sports footage. However, the interpolation algorithm introduces a slight input lag, measured at 15 ms, which may be noticeable to latency-sensitive gamers.
HDR Implementation
HDR10 support is integrated via a 10‑bit DCI‑P3 backlight system. The peak brightness of the panel is 300 cd/m², which is below the 400 cd/m² threshold considered optimal for HDR content. Colour accuracy remains within ±2 % of the target for HDR10, although contrast ratios fall short of the 1,000:1 standard used by higher‑end models.
Viewing Angle
The IPS flat model maintains luminance levels within 90 % of the peak value at ±60° from the center axis. In contrast, the VA curved model shows a slight reduction in brightness at extreme angles, dropping to 80 % at ±70°. Both models provide relatively uniform colour fidelity across the viewing field.
