No idea why you’re getting downvoted. HDMI 2.1 supports 10-bit 4k 144hz with no stream compression. So the answer, unequivocally, is that yes it can.
DisplayPort 1.4 requires DSC (stream compression) to do the same. DisplayPort 2.0/2.1 supports higher bandwidth but it is not common on displays at this point in time.
People have other understandable reasons for preferring DisplayPort over HDMI (Open vs. closed standards), but there is no disputing the fact that HDMI currently outclasses DisplayPort in terms of bandwidth and thus the limits of what kind of signals it can carry.
Yeah, that sounds about right. Every time I look up HDMI vs DP it seems they are basically exactly the same. One of them is always sightly ahead in some niche regard - they keep leapfrogging each other, so maybe now HDMI is in the lead but soon enough DP will overtake it - but in 99.9% of real world use cases they are basically the same thing. They’re both plug-and-play, easy to use and will get you the best picture quality your hardware can show you. It doesn’t matter what you use. (But use DP if you can because it’s nicer)
Heck, you can send DP signals over HDMI cables and vice versa. It’s all a sham!
