DisplayPort on 60hz monitor

[taranclan]

i have a 60htz monitor hooked up to my laptop (via hdmi), i'm wondering if dp supports 60htz cause u have a raspberry pi 2 i tinker with and it's can only do hdmi, i'm currently having to unplug/replug the hdmi into my pi, is this possible?

Well this is the sort of thing I'm tempted to say, "when you tried it, what happened?"

But the short answer is yes. Depending on the specific revision of displayport and hdmi, display port can display higher refresh rates at higher resolutions. Unless you're on an ancient revision and using an 8K monitor, then 60hz isn't going to be an issue.

Also, you could also see about getting an HDMI switch, something along the lines of https://www.amazon.com/Splitter-TeckNet-Bidirectional-Switcher-Supports/dp/B07SWJG2DY

Although on PC I prefer to use DisplayPort whenever I have the option, but the latest versions of both inputs are pretty similar/equivalent for most users and will support a wide range of refresh rates and resolutions.

You say that both the laptop and the pi 2 have HDMI. Does your laptop also have a Displayport connector? If so then it depends on the resolution of the monitor as well as the version of DP supported by the laptop and cable. You will need DP version 1.2 or above to do 4K 60Hz.

Edit: nullable's advised HDMI Switcher is best if you don't have DP on the laptop.

You should be okay as long as your display is no higher than 4K resolution. Still you should consider nullable's suggestion. The reason being that when you want to switch between displaying the laptop and Pi 2's output on the display, you will need to fiddle with the monitor's controls which may be embedded in menus. Plus there will be wear and tear on display buttons. A small inexpensive and easily replaceable switcher with just one button, may be more convenient and easier to use depending on the monitor controls. The only drawback might be reliability of the switcher and the need for a total of three HDMI cables.

Edit. A lot depends on the resolution of your monitor. It occurred to me that your laptop might only have HDMI 1.4 which cannot do 4K 60Hz uncompressed. If that is the case then you will need to try the DP output. However, at lower resolution such as 1440p or 1080p, HDMI 1.4 will do just fine.
