Hey there,
I have a HP compaq 2205 monitor that I have been trying to connect to my lenovo, but it won't work as it is telling me that no inout is detected. I use a "DisplayPort to HDMI adapter" as my PC only supports HDMI, and this adaptar had been working fine for many years.
I have tried:
-Reinstalling display adapters
-Switching HDMI cables
-Switching the power source cable
This is really frustrating as there is no reason it shouldn't work. My Laptop has integrated graphics, but that doesn't seem to be the problem.

Any help?
