I think I need a USB-C hub that

  • gets power from the monitor
  • does PD to the laptop
  • routes DisplayPort between laptop and monitor

Don't really want to have a separate power supply when the monitor can provide the power.

@juliank a long while ago I wanted a good PD monitor and I ended up with a pair of Dell monitors that are:

  • low DPI
  • have USB hub with several USB-A (2-3) and ethernet
  • can be driven by single USB-C cable from a laptop, while charging the laptop at 100W
  • can be driven by DP cable while providing USB over separate connection (e.g. typical PC case)
  • can, I kid you not, pair with a 2nd monitor over DP (multi-stream) for a single-cable dual head setup
  • not crazy expensive

Interested?

@zygoon I just bought this 4K 27" Eizo a couple months ago for 800€ or something. It has the USB-C connection and two USB ports, and I have chained a cheap hub to the monitor's first port, but the USB ports are only USB 2 speeds (with USB 3 protocol) when running in 4K.

@juliank my screens have working 10Gbit USB and they were far cheaper.

@zygoon Yeah but my goal is as high DPI as possible, I have no use for ethernet :D

@juliank oh and I forgot to mention both screens have 3 USB-C ports: one full feature PD, alt mode and data, one data without PD/alt mode and one for downstream devices. I can plug any USB-C accessory to the monitor and both power it and have it attached to my system. You could use this for any non-thunderbolt hub with any number of extra ports.

@zygoon Oh and of course, automatic brightness is the absolute killer feature.

@juliank yeah, I use similar stuff on apple monitors. BTW: all the screens I have at home work correctly with DCC - screen brightness and all that. I only wish it was better integrated with the operating system. No need to touch any of the buttons :)

@juliank right, I explicitly didn't want that (all the usual Linux woes with fractional scaling, random toolkits and such).

juliank,
@juliank@mastodon.social avatar

@zygoon I would have prefered 5K so I can run at 2x scaling, which is flawless, but it doesn't yet work over a single USB-C connection, and there's no monitors outside Apple.

But to be fair 150% scaling in GNOME/Wayland seems to work flawlessly too right now. Apps scale themselves, everything is sharp af.

Font scaling is a bit faster and produces smaller UI elements which is nicer.

@juliank my apple studio display works this way and works on Windows/Linux/Mac as a regular display.

I suspect things like the camera and some of the more advanced features (face tracking) are exclusive to MacOS though.

@juliank my experience with 150 was so bad over the years that my family has a number of 150% monitors I just gave them to use with windows, where they really work fine.

It's always that one thing that pisses you off and makes the experience terrible. It did get better, and by far, over the years but last time I tried Linux HDPI steam was totally broken so I just gave up again.

@zygoon Well the 4 apps (Chrome, Terminal, Dino, and an Eclipse app in a flatpak) I use work alright.

zygoon,
@zygoon@fosstodon.org avatar

@juliank try steam, I'm curious if it works better for you

juliank,
@juliank@mastodon.social avatar

@zygoon Ah I also use Keybase and that's not sharp.

zygoon,
@zygoon@fosstodon.org avatar

@juliank yeah, there's always something for $reasons.

Having said that, not sharp is okay. Steam was just rendered at 1:1 and looked tiny/unusable in parts of the window. I cannot explain how they managed that.

@zygoon I could have waited for the new one with has always USB 3 speeds but ugh I think it's like 1300€

@juliank @zygoon So you use DisplayPort, which only leaves the usb2 connection unused. Not sure what you expect more.

The builtin hub on the Eizo is crap, and my webcam doesn't work if connected there.
