The 42-inch model is LG's most compact OLED TV. It matches the performance of its larger counterparts for gaming, but its true strength lies as a PC gaming monitor. Unlike most TVs which are too large for a desk, the 42-inch display is a practical size. The combination of a smaller screen with native 4K resolution delivers a solid 104ppi pixel density. It features four HDMI 2.1 ports supporting refresh rates up to 144Hz at 4K. Additional gaming-centric specs include variable refresh rate (VRR), a 0.03ms response time, G-Sync compatibility, and 4:4:4 chroma sampling for razor-sharp text clarity.
The C4 is the 2024 entry in LG's popular mid-range C-series OLED family. Against standard LED/LCD TVs, an OLED display provides superior overall image quality, near-perfect black levels, an almost infinite contrast ratio, and incredibly fast pixel response. These attributes make the Evo OLED exceptional for showcasing 4K HDR content in all its detailed glory. The C4 utilizes LG's proprietary Evo panel, which achieves higher brightness and contrast compared to conventional W-OLED technology, similar to the QD OLED panels found in Samsung TVs. LG's OLEDs are highly regarded due to their long-standing market presence and continual refinements over multiple generations.
The LG Evo C-series is our top-rated gaming TV for 2025, thanks to its brilliant OLED picture and a robust set of features that maintain a reasonable price point. This model offers enhanced contrast and clarity over the already impressive previous-year C2. The visual experience is stunning, characterized by inky blacks, well-calibrated colors, and a crisp 4K picture. Once you experience OLED, it's difficult to consider any other display technology.
