Buying Guide for 42 Inch TVs

Display Technology: OLED vs. LCD

The most critical factor is the panel type. OLED TVs, like the LG C6 and C5 series, use self-lit pixels to deliver perfect blacks, infinite contrast, and vibrant colors from any viewing angle. They excel in dark rooms and for HDR content. LCD models, such as the Sylvania LC420SS8, are more affordable but rely on backlighting, which can lead to less deep blacks and narrower viewing angles.

Smart TV Platform and Features

LG uses webOS with Google Gemini and Microsoft Copilot integration in its 2026 models, offering intuitive navigation and voice control. Samsung relies on Tizen with Alexa built-in, providing a robust app ecosystem and seamless connectivity with other Samsung devices. Both platforms support major streaming services and offer free ad-supported channels. If you prefer a traditional LED backlight, the best LED TVs guide covers alternatives with different smart systems.

Gaming Performance

For console and PC gaming, look for high refresh rates, low response times, and HDMI 2.1 inputs. The LG C6 series supports up to 165Hz, while the Samsung S90F offers 144Hz. Both feature NVIDIA G-Sync and AMD FreeSync Premium for tear-free gameplay. The Sylvania LC420SS8 is limited to 60Hz and lacks VRR, making it unsuitable for competitive gaming.

Connectivity and Ports

Ensure the TV has enough HDMI ports for your devices. Most modern OLEDs include four HDMI 2.1 inputs, supporting eARC for high-quality audio. The Sylvania model offers two HDMI and one PC input, which may suffice for basic setups. USB ports, Wi-Fi, and Bluetooth are standard on all models here.

After careful comparison, we believe the LG 42-Inch Class OLED evo AI 4K C6 Series stands out as the ultimate choice for cinephiles and gamers who want cutting-edge picture quality and the highest refresh rates, while the Samsung 42-Inch Class OLED S90F 4K Smart TV offers a slightly more affordable yet still excellent OLED experience with robust AI upscaling and gaming features. Both deliver outstanding performance, and your final decision should hinge on whether you prefer LG’s webOS ecosystem or Samsung’s Tizen platform.

OLED TVs use self-lit pixels for true blacks and vibrant colors, while LCD TVs rely on a backlight, which can cause grayish blacks and narrower viewing angles. OLED is generally more expensive but offers superior contrast and response times. LCD models like the Sylvania are more affordable and still provide decent picture quality for casual viewing.
