Näyttöviiveen

Näyttöviive, often referred to as input lag or display lag, is the delay between an action initiated by a user and the corresponding visual update on the screen. This delay is an inherent characteristic of electronic displays and the systems that drive them. It is measured in milliseconds and can be influenced by various components in the signal path, including the display's internal processing, the graphics card, the operating system, and the interface connecting them.

In practical terms, high näyttöviive can manifest as a noticeable lag in video games, where quick reactions are crucial. It can also be perceived in general computer use, making tasks like typing or moving a mouse cursor feel less responsive. Different types of displays and technologies have varying levels of näyttöviive. For instance, high-end gaming monitors often feature significantly lower näyttöviive compared to standard televisions or older display technologies.

Several factors contribute to the overall näyttöviive. These include the time it takes for the graphics card to render a frame, the time for the signal to travel to the display, and the display's internal processing time to interpret and show the image. Users sensitive to this phenomenon often seek out displays and hardware configurations that minimize this delay to enhance their user experience, particularly in fast-paced applications.
