When is DisplayPort the best option?
DisplayPort cables can achieve a higher bandwidth than HDMI cables. If there's a higher bandwidth, the cable transmits more signals at the same time. This mainly has an advantage if you want to connect multiple monitors to your computer. Even when you game on your computer, it's better to use a DisplayPort cable to connect a monitor.
When is HDMI the best option?
