Hi there, I have a Lenovo X1 Extreme Laptop (Gen4), the hardware probe looks like this: https://bsd-hardware.info/?probe=d19db2828c , and the Lenovo specs: https://psref.lenovo.com/Detail/ThinkPad_X1_Extreme_Gen_4?M=20Y5001DMX
It has two graphics cards: 1. Embedded - Intel UHD (Tiger Lake) 2. Discrete - Nvidia GeForce RTX 3050 Ti Mobile 4GB I am trying to connect an external screen via the HDMI port, but with no luck so far. The output of xrandr shows: eDP-1 connected primary 3840x2400+0+0 (normal left inverted right x axis y axis) 344mm 215mm ... HDMI-1 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) DP-3 disconnected (normal left inverted right x axis y axis) DP-4 disconnected (normal left inverted right x axis y axis) I have connected my Dell screen via a HDMI cable, but I am unable to get a picture, and the output from xrandr remains the same. I tried running also: xrandr --output HDMI-1 --auto --output eDP-1 --auto That made no difference either... I guess because it shows HDMI-1 as disconnected? I realise that Nvidia cards are not supported in OpenBSD, and I have read that some laptops only have the HDMI port connected to the Discrete graphics card (Nvidia), whilst some have it connected to both graphics cards. How can I determine under OpenBSD if the HDMI port is connected to one or both graphics cards please? Additionally, if it turns out it is only connected to the Nvidia card. What are my other options for powering an external display? I am often travelling so need a small cable based (i.e. not a Dock) solution. The laptop claims to export DisplayPort 1.4 over Thunderbolt 4 as well. Would such an adapter from Thunderbolt 4 to HDMI be supported by OpenBSD - https://www.sonnettech.com/product/thunderbolt-dual-hdmi-adapter/overview.html ?
