Does This Connector Even Do Anything? - DisplayPort Explained

DisplayPort has been around since 2008 and is still used in computers today, but is there a reason why we haven't fully switched over to only using HDMI?

I remember when you guys tested hdmi and displayport cables using your cable tester. To see companies lie about the hdmi version they were using for the cable is absolutely ridiculous while every displayport cable passed at the rated spec.

One currently unutilized feature of DisplayPort is the auxiliary channel, which can carry a single 480mbps USB2.0 signal, which in theory would enable things like pen/touch input displays needing a single cable to the PC.

Huge advantages to displayport that got left out of the video:
1: Locking connection between the cable and port ( HDMI is just a light friction ).
2: Open source free license to use the port ( HDMI requires paying a license fee to use the port ).

Another important factor are industrial applications. Companies in this area absolutely hate friction connectors. They even have USB with screws.

You did not talk about the fact that they nerfed the certification on HDMI cables.
A 2.1 HDMI cable from one manufacturer might not have the same functions as one from a different manufacturer.
Ad to that the problem with all the different versions of HDMI and the fact that makers of TV´s and other things that use the port, have no problem saving a buck by downgrading, make the Displayport the go to port in my book.

One thing to remember about DisplayPort resolutions getting crazy high, is that daisy-chaining means you are practically running every screen together from one port. That means that 16K 60Hz support also means you should be able to chain 4 x 8K 60Hz monitors off a single connector, or for a more likely setup in the future, 3 x 4K 120Hz.

Also remember that DP daisy-chaining is used on laptop and tablet USB-C docks to connect multiple screens plus power and USB data to a device with a single cable. HDMI has nothing like that available.

I will also recall your video where you tested every brand off HDMI and DP cable you could get your hands on
HDMI: Hit and Miss
DP: 100% Works 100% of the time.

I recently got a 165hz monitor and learned it was capped at 144hz because of my hdmi cable. It seems like display port is the only option for refresh rates above that.

DisplayPort is royalty free, hence HDMI is unnecessary. Due to the licensing situaltion with HDMI (parts of the standard and optional features are proprietary), it's not possible to supprt the full featureset in opensource drivers (i.e. on Linux, *BSD).

DP is by far the best one. Best compatibility with analog adapters and digital adapters, while HDMI seems like it was made to give the user headaches, worse compatibility, trash cables, slower updates to revisions, not open-source...

At one of the last instances of WinHEC, in Los Angeles, there was a seminar on DisplayPort. The presenter was formerly an ATI (before the AMD acquisition) engineer who was now at Microsoft. As he explained it, DisplayPort got started when a bunch of video engineers at ATI were having a conversation and came to the general agreement that HDMI was a hamfisted mess that would never have come out of the PC industry. So they decided to start work on their own video transport and soon had many major companies across the industry interested.

They are historically different. HDMI evolved from DVI which evolved from VGA which evolved over few stages from analog video which can be traced back well to the 1920's/1930's. It can still be seen as an digitized analog RGB signal. The requirement of a constant frame-rate persisted over all this time. Displayport on the other hand was an development more or less from scratch and instead of obeying to TV standards it was designed for computers from the very start. Its more of a block transfer of addressed data like PCIe and not a constant stream. That is why it doesn't need a constant frame rate (so this is where G-Sync comes in) and can support multiple monitors with one cable. Displayport is the better standard at least for PC's.

AFAIK HDMI's extremely proprietary nature (even the spec are proprietary and aren't supposed to be available to the public) result in it having a fairly spotty support in terms of available features on some devices due to difficulty/impossibility of implementing those features in software.

Life was simpler when you had a choice between VGA, VGA, and VGA.

DRM is very restricting to things you bought yourself. Maybe companies should find other ways to monetize and remove DRM. Maybe you could do another video on that.

You forgot the most killer features: Display Port can carry usb 2.0 (over aux), so you don’t need another cable. HDMI can carry ethernet at 1gbps, I still have a receiver that supports this and delivers Ethernet over HDMI to my tv, which no longer supports it. /s

On a PC I prefer DisplayPort, and HDMI on TV
Plus most good PC monitors will have at least one DisplayPort

How long before USB Type C with Thunderbolt/USB 4 are the norm?

DisplayPort also syncs and unsyncs to my monitor all night after my displays time out and go into power saving. It makes the new-device and disconnected -device sound each time. Big fan

Air Traffic Control, Military and Avionics segments detest HDMI for varying reasons. Some even prefer to stick to DVI.
There will always be a split in the protocols, Consumer vs Industrial, until we do away with video cables... (not talking wireless).

seems like displayport is the way to go. Even taking open standards and licensing/royalties aside, which make displayport much easier to implement, even just the specs make the only real strength of hdmi its audio management, which any computer user should have separate speakers/headphones anyways.
