What initial picture setting should be checked on a TV after it has warmed up for 30 minutes?

When evaluating the initial picture settings on a TV after it has warmed up for about 30 minutes, checking the color temperature is particularly significant. This is because the color temperature affects how warm or cool the colors appear on the screen, and it can shift as the TV warms up.

During the warming process, the display technology, such as LCD or OLED, may experience changes in its color performance. By checking the color temperature setting, you ensure that the colors remain accurate and natural, reflecting proper white balance and overall color fidelity. Additionally, achieving the right color temperature is essential for a comfortable viewing experience, as it can greatly influence the visual perception of content.

While other settings like contrast, brightness, and sharpness are also important for picture quality, color temperature most directly addresses the dynamic nature of image display influenced by the TV's operational state.
