Hi,
I have
this PG278Q monitor and a USB-C-to-Displayport cable, running from a Lenovo X1 Carbon 7th gen with USB-C/Thunderbolt3 ports, but I can't seem to get it to work.
I can see in the monitor specs that HDMI-to-DP adapters aren't officially supported by Nvidia and rarely works (found in my search one exception with an active adapter (w/power)), but it says nothing about using one USB-C-to-DP cable (it's not an adapter, though I suppose it might work like one).
I can find several different cases where an Asus monitor worked with such a USB-C cable, even when it wasn't specified that it was supported, though nothing about my own specific model. I'm aware that G-sync won't work, but that's irrelevant to my case.
My laptop is fully updated with both newest bios, drivers and firmware (drivers/firmware for USB, thunderbolt and monitor included), USB-selective suspend is disabled, nothing in my BIOS is disabling the feature.
I'm guessing the monitor doesn't support USB-C-to-DP, but I'm hopeful and reaching out for solutions anyway.
Hope anyone can help!
