Driving a high-resolution monitor at a high refresh rate will consume more power regardless of whether it’s connected via DisplayPort or HDMI.
However, DisplayPort can potentially offer some power-saving advantages in specific scenarios. DisplayPort’s Panel Self Refresh (PSR) technology allows the monitor to refresh its display less frequently when the image is static, which can reduce power consumption. This benefit is monitor-dependent. Ultimately, the impact on battery life from using DisplayPort versus HDMI is usually negligible compared to other factors like screen brightness and overall system usage.
What is DisplayPort Alternate Mode (DP Alt Mode) over USB-C, and how does it work with my Dell laptop?
DisplayPort Alternate Mode (DP Alt Mode) over USB-C allows USB-C ports on your Dell laptop to transmit DisplayPort video signals directly through the USB-C connection. This means the USB-C port can function as a DisplayPort output in addition to its other functions like charging and data transfer. This functionality requires both the laptop and the monitor (or adapter) to support DP Alt Mode.
When a Dell laptop supports DP Alt Mode, you can connect a DisplayPort monitor using a USB-C to DisplayPort cable or adapter. The laptop’s graphics processing unit (GPU) directly sends the DisplayPort signal through the USB-C port, providing the same video and audio quality as a standard DisplayPort connection. This simplifies connectivity and reduces the need for dedicated DisplayPort ports, especially on thin and light laptops. Check your Dell laptop’s specifications to confirm if its USB-C port supports DP Alt Mode for video output.
