To me at least, it seems like it has a lot of potential in it. Does it have drawbacks (i.e. Latency, cost of implementation, reliability, etc.), or is it just not needed at this current stage? Does Linux work well with it?
I live in an area where monitors with HDMI is not common, let alone DisplayPort, so I've never used it before.
People like paying for the hdmi license
DisplayPort is slowly making it's way in, maybe in 2yrs we'll have a different discussion
DisplayPort also has some features not found on HDMI such as the ability to daisy-chain multiple monitors to a single connection:
It also has increased bandwidth and allows for longer cable runs without as much degradation compared to HDMI:
As far as downsides go you can't transfer Ethernet over DisplayPort but you can do 100 Mbps Ethernet over HDMI, I actually have one of those cables in my house somewhere.

Yes, I am on Linux right now with 2 DisplayPort monitors connected to my GTX 970, one is a 28" ASUS 4K and the other is a 25" LG 2560x1080 Ultrawide and haven't had any major issues with it.
Thinkpads have had DisplayPort connectors on them for quite a while now, same goes for Dell Latitudes (and nope, for the longest time they didn't even have an HDMI port).
The main advantage of DisplayPort is that it's packet based as opposed to being a continuous signal. That's what allows for daisy chaining and switches (only the correct device will do anything with the packet), and also increasing the bandwith without breaking compatibility.
I think Apple were pushing DisplayPort adoption using Intel Thunderbolt, but other manufacturers didn't pick it up. Now it appears that Apple are going to be ditching the mini-DP-style connection across the board in favour of USB type-C.
It seems that most people with medium-high end setups use DP rather than HDMI. It's just a matter of preference/practicality really, considering how similar the two interfaces are.
He's talking about monitors, I think? Not laptops, desktops etc.
one most non techys do not have anything that can output DP.
two most of the market is using 1080P which is just fine over HDMI.
three america is so slow on the uptake of anything new that we will not get any DP until revision 5 or 6.
There are few markets where people massively buy stuff that has not been adopted by the enterprise market.
Most beamers in companies are still connected through a VGA D-connector, which means that enterprise grade laptops at least need a DVI-A connector to be bought, which can then be adapted to VGA and HDMI, but not to DP.
Very few people are interested in high resolutions than 1080x1920. It's something that is hyped a lot, but few people actually benefit from using it, only people that need more teal estate, like programmers, DTP-ers, digital artists, higher-than-broadcast-grade video editors, etc... actually need a higher resolution than 1080p.
Unless the Internet bandwidth for the majority of people in the whole world would rise considerably, this situation will just remain, because higher than 1080p video can't be sold to the public, so there is no need for higher resolution capable equipment. That means that HDMI will stay the de facto world standard for a very long time to come.
HDMI came earlier and took the market. End of story.
It also has "HD" in the name, so...
hdmi has audio
dipslapy port does not
Outside of PC like in entertainment things that like DRM DP does not currently support HDCP so will not be used there.
That is actually false.
Displayport does have audio capabilities
Q. Does DisplayPort also support audio?
A. Yes, DisplayPort supports multi-channel audio and many advanced audio features. DisplayPort to HDMI adapters also include the ability to support HDMI audio.
:)
;)
i guess we need to find those displays that have audio IO
Would be a treat to have a DP panel with audio IO! DP's been carrying audio for a good while now but with a lack of things to plug into it's just been a bullet point on the spec sheet.
As mentioned in @MichaelLindman's DisplayPort vs HDMI Link,
DisplayPort Doesnt support "Consumer Electronics Control (CEC)", which lets users control enabled devices with one remote control.
So you could control your DVD/Bluray player with your TV remote as long as you use HDMI.
@meetowl It is slowly making it's way in. The last batch of Optiplex 3040s and monitors that I deployed came from Dell with DP output on the Optiplex, DP input on monitors, and included with a DP cable. It is just going to take awhile for it to proliferate since most desktops are considered to have a 3-5 year service life and most work environments tend to replace only as needed.
In home use cases I feel like HDMI is more popular because not only is it a more mature technology, but also the game consoles, TVs, HTPCs, etc. can all use HDMI as a common video delivery technology.
Adoptation is so slow because most consumers have no real need for it. For 1080p @ 60Hz, even HDMI is overkill.
Hell, the only reason I'm using HDMI on one of my (two) monitors right now is because my 1070 only has 1 DVI output. On my previous 770s I was running dual DVI just fine.
That is because they do not know they are paying for it ! (lol)
