The maximum length of a DisplayPort (DP) cable depends on various factors, including the version of DisplayPort, cable quality, and resolution/refresh rate requirements. In general:
DisplayPort 1.1 and later versions support cable lengths of up to 15 meters (about 49 feet) without the need for signal boosting or other active measures.
For longer distances, active cables or signal boosters may be required to maintain signal integrity. Active DisplayPort cables can extend the maximum length to 30 meters (about 98 feet) or more, depending on the specific cable and setup.
Fiber optic DisplayPort cables can extend the maximum length even further, up to 100 meters (about 328 feet) or more, making them suitable for long-distance installations in commercial or professional settings.
Ultimately, the maximum length of a DisplayPort cable will depend on your specific requirements and the capabilities of your devices and cable infrastructure. It's essential to choose the right type of cable and consider factors such as resolution, refresh rate, and signal integrity when planning your setup.
