I want to connect my monitor (Acer XF270H) to my Lenovo Yoga 920 4K laptop. I'm using a USB-C to HDMI Adapter with a normal HDMI cable running from the adapter to my display. My display doesn't work with my phone plugged in either so I have no idea whats happening. When I plug the adapter into my laptop my laptop goes immediately dark and I can't see anything on my laptop either? I know it's not the HDMI cable or the ports because I have a PS4 I plug them into and it works great and the adapter works great too when I plug the HDMI adapter into my TV in my living room. I really want this to work because I'm heading to college in about a month so if this doesn't work this blows.
