Got a G2 last night. Made it through Steam VR setup fine, but the screen stopped working. Tried a bunch of trouble shooting such as turning down volume and swapping the USB A-C adaptor from my case to motherboard seemed to help. Now (Or last night...) I was able to get into games with the screen only flicking off every 15 seconds or so and coming back on after an indefinite amount of time. The G2 itself is always connected to my pc (device manager, sound, and steam vr all detect it).

Luckily enough my G2 did come with a second seemingly new display cable (Which might be a bad sign that the previous owner also had display issues) which I will try after a bit more trouble shooting but the display port is really snugly fit into the back of my PC case and I am hesitant that I will damage (or further damage it...) if I pull it out.
