Hey there,
I do own a nice new t470s bought by my employer. As I dont do any HPC locally and got most of my data in a storage server anyway I was thinking about replacing my desktop by an Ultra Dock (not the usb3/thunderbolt but the classic one).
Therefore I would need to power two different monitors, one UHD, one FHD upright.
Is this possible with the Ultra Dock running a current Arch?
The wiki states:
"We have tested with the Thinkpad Ultra Dock and are able to utilize multiple HiDPI monitors via individual connections (e.g. no display port chaining). "
(
https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_T470s )
while ThinkWiki states
"Linux does not yet offer explicit support for the DisplayPort MST hub built into this dock, so multi-screen support is not fully functional under Linux. A single screen works fine and is fully controllable, but multiple screens are handled by a some unconfigurable fallback mode, and appear a single display; they cannot be individually configured in terms of resolution, relative position etc."

I think the information at thinkwiki may be outdated heavily. I wonder what archwiki means by "utilze". It wont help me if both displays show the same content and I also dont want to connect to any of the T470s ports.
So my question is, can I use two different monitors connected to the Ultra Dock without them showing the same output?
Does anyone have experience?
I dont want to buy one and pay for it if it is useless to me.
Thank you in advance!
