DisplayPort is known for its higher resolution and refresh rate. After HDMI, DisplayPort is overgrowing because of its high refresh rate capability with great resolution. It gives more refresh rate and resolution than any other video interface.
But, there are different versions of DisplayPort, so all the versions have different resolutions and refresh rate capabilities. Thus, a buyer should have strong research before buying the DisplayPort.
To help you out by informing you which versions support what resolution and refresh rate, I’ve brought this article here, so let’s check it out and find out what version will meet your need.
Refresh Rate & Resolution of DisplayPort
After launching in 2006, there are many versions of DisplayPort, so all of them support different resolutions and refresh rates. With every upgrade, DisplayPort supports a better resolution and refresh rate.
| DisplayPort Versions | Resolution | Refresh Rate |
| DisplayPort 1.0 | 1080p | 144Hz |
| DisplayPort 1.2 | 4k 1080p or 1440p | 60HZ 144Hz |
| DisplayPort 1.3 | 4k | 120 Hz |
| DisplayPort 1.4 | 8K 4k | 60hz 120hz |
| DisplayPort 2.0 | 16k 8k 4k 2k | 60Hz 120HZ 144HZ 165HZ |
The refresh rate goes up when the resolution goes down, so you can increase the refresh rate by decreasing the resolution and vice versa.
DisplayPort will not just serve your higher resolution and refresh rate; firstly, the Computer [GPU] and DisplayPort should support a higher resolution or refresh rate.
Meaning if you’re picking a DisplayPort for 8k, but your Computer [GPU] and Display do not support that much resolution, then it is just a waste; you’ll only get the resolution as supported by your Monitor and computer.
Here I’ve listed a few good-quality DisplayPort cables of different versions; check it now.
DisplayPort Vs. HDMI Refresh Rate & Resolution
| DisplayPort Versions | Resolution & Refresh Rate | HDMI Versions | Resolution & Refresh Rate |
| DisplayPort 1.0 | 1080p @ 144 Hz | HDMI 1.0, 1.1, 1.2 | 1920×1200 @ 60 Hz |
| DisplayPort 1.2 | 4k @ 60 Hz | HDMI 1.3 | 2560×1440 @ 60 Hz |
| DisplayPort 1.3 | 4k @ 120 Hz | HDMI 1.4 | 4k [3840×2160] @ 30 Hz |
| DisplayPort 1.4 | 8K @ 60 Hz | HDMI 2.0 | 4k [3840×2160] @ 60 Hz |
| DisplayPort 2.0 | 16k @ 60 Hz 8k @ 120 Hz | HDMI 2.1 | 8k [7680×4320] @ 60 Hz 4k @ 120 Hz |
So if you’re a High-end PC user, DisplayPort is a better choice than HDMI, not because it will serve the best resolution and refresh rate, but because it also supports adaptive refresh technology like G-Sync and Free-Sync.
Moreover, you can connect multiple monitors only by using one DisplayPort cable, but the monitors should support the DisplayPort daisy chaining. However, you can also use an MST Hub to connect different monitors or to do daisy chaining.
If you’re gaming or streaming on a High-end PC, then DisplayPort can be a game changer for you. It also makes your setup future-proof, as various sources claim that high-end GPUs will only support DisplayPort in the future.
So if you’re investing a good amount, getting a DisplayPort setup rather than an HDMI is better. For normal use, you can definitely go with an HDMI.
