USB-C monitors
Hi guys, I am on -current and considering to purchase a USB-C monitor (power delivery to my Thinkpad over one cable). Do USB-C dislplays work on OpenBSD? Thanks in advance Jan
Re: USB-C monitors
Yes, I've used that with a couple different monitors, and a handful of usb-c to hdmi adapters. All worked fine, and behaved just like normal hdmi/dvi/vga monitors. Power delivery and usb also worked as expected.

Re: USB-C monitors
Hi Peter, thanks for your prompt response. I believe it should work (it is actually a usb-c monitor, no usb-c to hdmi adapter needed). Nevertheless I'll just take my laptop to the store and try it, just to be sure it really works.

Hi, My experience is the same as Peter's. No problem with various adapters USB-C to HDMI, in my case at 4k both 30Hz and 60Hz. I had no luck with DisplayPort output on a couple of docking stations. Will try next week with a direct cable USB-C to DP and will be able to report on that. Cheers, Paco. On Sun, 19 Sep 2021, Jan Betlach wrote: > Hi Peter, > > thanks for your prompt response.

Re: USB-C monitors
Just be aware that if you are looking at 4k monitors ; you will be likely be limited to 30hz refresh rate via most adaptors using DP mode over USBC. Thunderbolt3 and 4 can do 4kp60 as can DP 1.4 - but there are various factors involved including the adaptors SoC, your GPU/Motherboard output. Things can definitely go pear shaped if you are doing anything over 1080p. On Mon, Sep 20, 2021 at 4:25 AM Paco Esteban wrote: > Hi, > > My experience is the same as Peter's.
