From the transcript and ai generated summary from Claude:
Here is a summary of the key points from the Linus Tech Tips YouTube video on why DisplayPort is better than HDMI:
DisplayPort has an embedded mode (EDP) used in laptops and tablets to drive internal displays in a simpler, thinner way vs HDMI.
DisplayPort has a USB-C alt mode to deliver signals over USB-C ports, enabling charging and video over one cable. HDMI's alt mode was discontinued.
DisplayPort is royalty-free while HDMI charges device makers a per-unit royalty fee.
DisplayPort supports multi-stream transport for daisy chaining multiple monitors from one output.
DisplayPort can easily convert to HDMI signals via passive adapters, but not the reverse.
DisplayPort cables often have latches to lock them in place, preventing accidental disconnections.
Key advantages of DisplayPort are higher bandwidth, more flexibility, lower costs, and convenience features over HDMI. But HDMI remains widely used due to broader consumer electronics adoption.
In summary, the video makes the case that DisplayPort is technically superior to HDMI in several ways, though market dominance of HDMI persists. Both serve an important role in connectivity.
Thank fuck for this ai summary, it took seconds to read. I opened the video just to see how long it would take to watch it. 5 minutes of life would be gone, god damn it.

Good human
Do you know why we generally don't use DisplayPort instead of HDMI? I'm always interested in how lesser technologies proliferate.
HDMI came from the TV manufacturers and was earlier than DP. While DP came from VESA and Computer OEMs.
HDMI being in TVs gave it a far wider penetration in the consumer market, and so when people wanted to hookup their laptops and other devices to TVs, they'd need HDMI.
Ironically, as ports have been simplified to almost just USB-C on many devices, DP's market share actually grows as it's cheaper and easier to include for OEMs, and if the consumer has to buy an adapter anyway, it might as well be on their dime to pay for HDMI, rather than the phone or laptop maker.
HDMI came around four years earlier than Display Port, so one of the reasons is that it has been around longer, therefore allowed mass adoption, first mover advantage.
Ahh makes sense. Seems like USB A vs C a little bit. Except C is so much better I get to deal with both lol
In that case, USB A came out right 20(?) years earlier than C - I'm guessing here, don't slay me.
There were USB patches for windows 95 to add the support in
Pretty close. It's debatable at exactly what moment a cable "comes out" (is it when the specification is finalized? When it's published? When device manufacturing starts? When a popular consumer device first has it?) but my personal opinion is 1996 and 2017 for USB-A and USB-C, so 21 years difference.
And here I was concerned about exaggerating...
Awesome!
