Näyttöyhteys

Näyttöyhteys refers to the connection established between a display device, such as a monitor or projector, and a source device, like a computer or media player. This connection enables the visual output from the source device to be rendered on the display. The type of näyttöyhteys used can significantly impact the quality of the image, including resolution, color depth, and refresh rate.

Historically, analog connections like VGA (Video Graphics Array) were common. These transmitted video signals as continuous analog waveforms. However, analog signals are more susceptible to interference and degradation, leading to a loss of image quality, especially over longer cable runs.

Modern devices predominantly utilize digital näyttöyhteys standards. HDMI (High-Definition Multimedia Interface) is one of the most prevalent, supporting high-definition and ultra-high-definition video resolutions, along with multichannel audio and network data transmission over a single cable. DisplayPort is another digital standard, often found on computers and professional monitors, known for its high bandwidth and support for advanced features like variable refresh rates. USB-C, a versatile connector, can also carry video signals through protocols like DisplayPort Alternate Mode, allowing a single cable to handle power, data, and video.

The choice of näyttöyhteys depends on the capabilities of both the source and display devices, as well as the desired image quality and features. Ensuring compatibility between the devices and the chosen connection type is crucial for optimal performance.
