Would USB-C to DVI work?

[Yefee]

May I ask if the USB-C to DVI works? Have no chance to test it on my own.

I have tested USB-C to DP with a samsung 4k monitor.
Always get Kernel Panic when you plug this monitor in or boot with this monitor plugged in:

Thanks! I will try. Forgot to mention that mine one is UHD internal display. Internal screen won't work while using FB_id = 0x0100518A.

I have noticed one thing, when external monitor stays connected and laptop goes to sleep mode (same thing with HDMI), OS will be restarted.

Hi @wzygadlo, could you please let me know if USB-C to DVI works?

Unfortunately, I do not have cable usb-c to DVI so not able to test it, I do HDMI to DVI and that works...

@wzygadlo Thank you! It is enough.
