USB Type-C is such a mistake for video connectivity. It just doesn’t work most of the time and when it works, any tiny move of the USB Type-C cable breaks it do

USB Type-C is such a mistake for video connectivity. It just doesn’t work most of the time and when it works, any tiny move of the USB Type-C cable breaks it down.

This has not been my experience at all with DP in lightning and USB ports.

  Lightning doesn’t support DP, does it? There are lightning to HDMI adapters, but these fascinatingly run a full SoC that receives and decodes a compressed H.264 video stream over lightning, which I wouldn’t really call HDMI over lightning.

    Oops. I meant Thunderbolt. Terrible naming decisions were made.

      Never underestimate the amount of pain engineers will subject themselves and others to, all in service of a clever pun.

That's why you should buy an expensive cable that comes with shielding. Most likely the Type-C cables that said USB4 compilant would do

  Monoprice has relatively cheap USB4 cables in 3 ft (40Gbps) and 6 ft (20Gbps) versions. I've gotten a bunch to replace my previous mess of different cable types.

I use USB-C-to-DP cables as well as full Thunderbolt and haven’t had issues with them. USB-C cables can be garbage, so you probably need to get a better one.

  Well, here is one example. I use the cables that came with the portable monitor. When I use a miniHDMI cable, no problems. With USB-C the monitor drops the connection and blinks every so often. Here is another example. A coworker came crying that her monitor is dropping connection. We’ve tried an HDMI cable (this is a full size monitor connected to a laptop), problem disappears. It’s a difference between working reliably (like an HDMI cable) vs working sometimes, if you are lucky.

it's 2023 and I can't plug my phone into a dock or monitor without fancy bits. At least I can plug in a USB and and it can act as a host. The _only_ reason I want a linux based phone is so I can just use my phone like a normal device. The software implementations (who remembers MTP?) for phones kills its usability as a general purpose device.

  What do you mean by "fancy bits?". I can plug my Galaxy S23 into the same dock as my Macbook Pro and use DeX with video out and my keyboard and mouse without installing or doing anything other than clicking "ok".

I‘ve personally had similar issues with both “real” mini DP as well as USB-C to DP cables, adapters, or USB-C native monitors. Conversely, I’ve also used USB-C video without any hiccups in other device constellations. It depends much more on the combination of monitor, source, and cable, than on native DP vs USB-C, in my experience.

I have a portable USB C monitor that gets power and video from one cable. Why is it a mistake? This is my “universal” cable; https://www.amazon.com/dp/B093YVRHMB https://www.amazon.com/dp/B093YVRHMB - USB A and USB C on one end. - USB C, micro USB and lightning on the other end. - 100 W charging support - 10Gbps data transfer - supports video over USB-C

I've had the same experience. Especially when you're trying to daisy chain or use anything very high bandwidth. I've tried different cables too but the mating just isn't solid enough and small bumps kill the link.
