What is input lag, and why is it important for gamers?

Input lag is the delay between pressing a button on a controller and the action appearing on the screen. For competitive gaming, minimal lag is critical, as even 10–30 milliseconds can impact performance.

How do I enable 'Game Mode' on my TV?

'Game Mode' is typically activated manually through the picture settings. On some models (e.g., Samsung, Vizio), it can be applied to any profile, while on others, it appears as a separate menu option.

Does resolution affect input lag?

Yes, input lag can vary depending on the resolution. Testing revealed that 4K HDR sometimes shows different lag metrics compared to Full HD.

Quick answer

The best gaming TVs of 2026 offer minimal input lag and high picture quality for PlayStation 5 and Xbox Series X consoles.

CNET experts conducted a detailed analysis of gaming TVs available on the market in 2026, focusing on two key parameters: input lag and picture quality. Testing was performed in a specialized lab with controlled lighting, where models were compared under identical conditions. Scientific instruments, including the Konica Minolta CS-2000 spectroradiometer and Murideo Six-G signal generator, along with CalMan Ultimate software, were used to analyze brightness, contrast, and color accuracy.

Special attention was given to support for modern gaming features such as 4K HDR, 120Hz refresh rates, and VRR (Variable Refresh Rate) technology. Xbox Series X and PlayStation 5 consoles were used to verify compatibility with high graphics settings. The 'Game Mode,' which reduces input lag, was tested on all models: in most cases, it must be enabled manually, while on some devices (e.g., LG OLED), it only works at 60Hz.

Results showed that high-end TVs with advanced video processing benefit the most from enabling Game Mode, though it may slightly degrade picture quality. For most gamers, the difference between 10ms and 30ms of input lag is negligible, but in competitive games, even minimal delays are critical. It was also found that input lag can vary depending on resolution, with 4K HDR sometimes showing different metrics than Full HD.
