Me neither. I play at 1440p/120hz. Both cables can manage that resolution and frame rate.

The only difference I get is when I use DisplayPort and leave my computer alone for 20 mins, the GPU goes to sleep and the monitor won't display anything although I hear background apps/games running.

Without changing any settings, using a HDMI cable solved that.

HDMI it is.

its starts i matter more when you do more exotic connections. display port is more friendly for merging it into another form factor, and between the two, the only one capable of tech like daisy chaining monitors.

hdmi also requires a licensing fee to use, which technically add a cost to the end user.

In a multi monitor set up, when a screen connected to display port goes to sleep my computer treats it like that screen was disconnected - meaning all my open applications get shoved from one screen to another. I've also used HDMI to avoid that.

On the other hand, when I turn off my second monitor (on HDMI), all my apps stay on that screen, meaning I have to manually move them over to my main monitor where I can actually see them.

And if my DisplayPort monitor is off and everything's on my second monitor, when I turn the main one back on all the windows go back to where they used to be (al least on Plasma Wayland).

That's interesting, though not my experience. If a monitor is turned off then the PC picks up that it has disconnected.

The scenario I described occurs when the OS (Windows) sleeps the screen after inactivity. It could be a function of the laptop, of the monitor, or of the cables. In my set up using HDMI over display port solves it.
