If a laptop with 720p display is connected to a monitor with a 1080p display will the image on the monitor be 1080p or 720p?

When a laptop with a 720p display is connected to a monitor with a 1080p display, the image on the monitor will typically be displayed at 720p resolution. The laptop's output is limited by its native resolution, so it will upscale the 720p image to fit the 1080p monitor, resulting in a lower-quality image that may appear less sharp. However, some settings or software may allow for adjustments to output at a higher resolution, but this depends on the laptop's capabilities.
