What maximum resolution and refresh rate does DisplayPort support?

1920x1080 and 60 Hz
1920x1200 and 100 Hz
2560x1440 and 144 Hz
2560x1600 and 120 Hz

The correct answer is: 2560x1600 and 120 Hz

DisplayPort is a digital display interface that was developed to replace older interfaces like VGA and DVI. It supports a maximum resolution of 2560x1600 and a refresh rate of 120 Hz, making it suitable for high-resolution and high-refresh rate displays. The other options are incorrect because they either have a lower resolution or a lower refresh rate. Option A is a popular resolution for HD displays, option B has a higher refresh rate but a lower resolution than the correct answer, and option C has a higher refresh rate but a lower resolution than the correct answer. Therefore, option D is the best choice for optimal display performance.
