😂 Oh, joy, another thrilling tale of a guy connecting his fancy #MacBook Air and prehistoric #FreeBSD desktop to a monitor! Thank heavens he discovered that #USB-C can do it all in one cable while his FreeBSD still hobbles along on good old #DisplayPort. 🖥️ Truly groundbreaking stuff, Ruben! 🌟

Gadget Review: DisplayPort to HDMI Showdown
https://shkspr.mobi/blog/2025/05/gadget-review-displayport-to-hdmi-showdown/
From crummy old S-Video, through SCART, VGA, and HDMI - the world of video connectors has never been entirely cross compatible. Oh, sure, with enough boxes and adapters you can usually get an old device to talk to a new one. But results are never guaranteed and quality can take a hit.
HDMI was supposed to be our saviour, but now DisplayPort threatens its dominance. What's the difference? For the average user - nothing. They both carry high-fidelity video and audio at resolutions higher than the human brain can interpret. Unless you are trying to pump 8K streams 5cm from your eyeballs at 200Hz, you're not going to notice the difference between the standards. They both do surround sound which your home cinema speakers are woefully under-specced for.
The main differences boil down to:
- DisplayPort has a spring-loaded latching mechanism which prevents cables coming loose.
- Lots of laptops and phones support DisplayPort via USB-C's DP Alt Mode.
- DisplayPort monitors can be "daisy chained" to each other.
- HDMI supports ARC (Audio Return Channel) which means your screen's sound can be sent back down the HDMI cable to an amp.
- DisplayPort uses Packetized Data Transmission which, in theory, is more efficient than HDMI.
But, in the end, it all comes down to this:
- What port your screen has.
My USB-C Docking Station has two DisplayPort outputs and a single HDMI socket. My 4K Vertical Monitor has DP, but my older monitor is stuck with HDMI. Is there anything I can do to convert the DisplayPort signal from my USB-C hub into an HDMI signal the monitor will understand?
Yes!
The good folks at Benfei have chucked me a couple of their adapters to test out. Let's put them through their paces.
Here's their 4K one:
And their 1080p one:
Rather handily, there are little instructions on the dongle to tell you which end is which.
The important thing to note is that they are both "plug and play", no drivers needed.

The main difference between the cables is that the lower-resolution one has a locking latch on the DisplayPort end.
I just couldn't get the lower-resolution one to work. My laptop saw it, it identified the monitor and its available resolutions, my sound output could be routed to it - but no video appeared. Yes, I tried rebooting and updating, and unplugging, and sacrificing a chicken - no dice.
The other one worked perfectly. Video came through crisp and clear. Instant detection. Like any modern electronics, it did get a little warm with constant use - but nothing too serious.
Bonus Flipmo Selekta!
What if you want to go the other way? Converting HDMI to DP? Let's go!
Wait? Why is there a USB plug on this thing?
The standard DisplayPort can supply 3.3V @ 0.5A. That's usually enough to power a converter chip. However HDMI can only do 5V @ 0.05A which is insufficient to power anything useful0.
Does it work? Yes! The USB plug is only used for power - it doesn't require any drivers or configuration. Plug it into your laptop or hub, plug the HDMI jack into your port, run a DisplayPort cable from it to your monitor. Done.

HDMI 2.1b will support higher power - but those are pretty rare. So a USB plug is needed to power the converter. ↩︎

General Purpose Media Interface (GPMI): китайский ответ HDMI и DisplayPort. Что это за технология?
Представьте технологию, благодаря которой один-единственный кабель способен передать изображение в 8K, звук, данные, интернет и даже зарядить ваш ноутбук мощностью до 480 Вт. Это не фантастика, а реальность. У нее есть даже название — General Purpose Media Interface (GPMI). Китайские разработчики представили новый стандарт в апреле 2025 года. Разработала его не одна компания, а крупный альянс Shenzhen 8K UHD Video Industry Cooperation Alliance , куда входит более 50 технологических гигантов, включая Huawei, TCL и Hisense, GPMI. Но что это за зверь такой и сможет ли он действительно вытеснить привычные нам HDMI, DisplayPort и даже USB-C? Давайте разбираться!

Alle Buchsen haben 40 Pins bei 2,1 cm. Die des 1. Boards haben die Kontaktfläche scheinbar hinten direkt, die des zweiten hat nochmal Einzelbuchsen für die oberen Stecker. Die Display-Buchse ist metallisch.
Was zur Hölle kauft man da für ein Kabel?!
Finde solche metallischen Stecker:

If anyone is working with a JetKVM and needs a DisplayPort to HDMI adapter that works then this lower cost device seems to do the trick:
https://www.amazon.co.uk/dp/B081GMCNNF
~£7 or so and seems to work with the test machine I have here (an HP Prodesk G4) which only offers Displayport output on the unit I have (an HDMI module for the HP is available).
You might come across USB issues with the HP Prodesk devices and the JetKVM but you can alter the USB HID setting for the JetKVM via the Settings -> Hardware -USB Devices section 😊
Not having a Grub boot menu to switch between Kubuntu and Windows 11 would probably help here 🤷♂️🤭
The KVM seems to be working in Windows 11 and Kubuntu.
As much as I dislike Apple no idea why #Mini_DisplayPort #DisplayPort is not more used considering its free to use, would be SO MUCH better for #SBC computers, instead of shiddy #HDMI

Es gibt ~aktive Adapter von DP auf eDP. :D
Ich bräuchte gerade aber anders herum…
@jherazob TBH, I think we all should standardize to #USBc with #PowerDelivery & #DisplayPort!
OFC it would've been cheaper and easier to stick with HD-SDI over Fiber, 7,9*5,5mm barrel jack @ 20V DC, PoE++ (802.3bt Type 4) and USB-C but sadly #Marketing wins over #TechSuperiority.

Mit #GPMI hat China einen neuen Standard für #Kabel entwickelt, der eine hohe #Bandbreite bei gleichzeitiger #Stromversorgung verspricht. Dagegen sehen #DisplayPort, #USB oder #HDMI alt aus. https://winfuture.de/news,150138.html?utm_source=Mastodon&utm_medium=ManualStatus&utm_campaign=SocialMedia
Well, I should have thought of this before but the USB 4 ports on my new X870E mainboard do offer DisplayPort output from the AMD 7000 CPU onboard Radeon Graphics.
It's only Displayport 1.4 with HBR3, so a maximum of 4K 60Hz, but I'll take it. Working fine at 2K 144Hz. Two monitors now up and running.
In an surprising display (to coin a phrase) of forthought I even have the correct DP to USB C cable on hand!
Sometimes the odds really are in your favour 😊
Now to work out why the Nvidia GPU isn't working very well with Windows 11 and the correct drivers installed.
Does anyone have experience running #DisplayPort signals over a FPC flat cable?
I want to reuse this laptop panel...
Dear single board manufacturers and designers
You know that #DisplayPort is a thing, do you?
Niche request. Does this "tablet as monitor" tech exist to buy yet?
- a tablet device;
- with USB-C;
- that supports DisplayPort over USB-C;
- as an incoming audio-video signal;
I.e. a tablet that can double as a monitor. Does this exist?
