Hi Nick. I ran into a similar-ish problem about a year ago. Sat down at a desk at TPL and plugged my Mac into the Dell docking bay attached to a Dell monitor ... and nothing happened. I was informed by local staff that this was expected - because Dell uses a proprietary style of docking bay (standard USB-C port, non-standard behaviour). Essentially, it doesn't work unless you have a Dell laptop. Dell sometimes makes good products. But I've been bitten by their inclination to "proprietary and our way is best" often enough that I avoid their products on principle and assume that problems like this are a result of choices they made. This may not be true, but you should look into how that "engineering laptop" of yours is designed and what it supports instead of assuming that the portable monitor was at fault. I bet it would work with a Dell portable monitor ... Kind of hard for me to whinge about proprietary lock-in in the same sentence in which I admit I was using a Mac - but Apple has always been very clear that they have a walled garden (and they fully follow the USB-C spec). Dell doesn't make their proprietary behaviour clear. On Wed, 31 Jul 2024 at 15:05, Nick Accad via talk <talk@gtalug.org> wrote:

3. I ended up getting this: https://www.arzopa.com/collections/hot-deals/products/s1-table-15-6-fhd-port...
It worked.. "OK", niot great, my main complaint is that the USB-C connection is a hit or miss, it worked on an Android phone for example, but it did not work on my souped up Dell/Windows laptop, and the support response is "just use USB-C for power and use the HDMI for display". Yup, it's going back.
The display specs say: Input Interface: Mini HD(Video Signal), Type-C Full Function(Video Data, Power Supply ISDN),
I don't know what Mini HD is, but I would guess that it is really Mini HDMI. <https://www.howtogeek.com/745530/hdmi-vs-mini-hdmi-vs-micro-hdmi-whats-the-difference/>
Mini HDMI isn't that common. I think Raspberry Pi uses it.
USB 3.x can and often does support Power Delivery, and DisplayPort at the same time.
If your computer is new enough, you only need a USB C male-to-male cab.
If not, you need a Mini HDMI cable and a USB C charger.
Or did I misunderstand somehting? --- Post to this mailing list talk@gtalug.org Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
Nope you got it, the usb-c to my laptop didn’t even detect a device. And my laptop is really top of the line, we get what we call “engineering laptops” from Dell, mine is not even a year old.
I could technically get a usb-c to hdmi adapter, but I was hoping for a single cable a la thunderbolt.
I’ll check in later if I find something that works
