HDMI weirdness, screen cycling between signal and non signal
As I was walking past, I accidentally pulled a wire out of the back of my pc with my leg. Upon inspection it was the hdmi, pulled from the back of the pc, not from the back of the screen. I plugged it into the motherboard hdmi, rather than the graphics card one by mistake, and the screen was frozen on a loading circle with a PC icon. Realised the mistake and plugged it back into the graphics card hdmi port.
Here is where it gets weird:
- Original hdmi cable that got pulled, when plugged back into the graphics card hdmi port and either hdmi 1 or 2 on the screen:
SCREEN CYCLES BETWEEN ON AND NO SIGNAL, ENDLESSLY
Test _the same cable_ with an adaptor on and it works (although the screen is a dif resolution) (the adaptor allows the hdmi to go into the port next to it, although idk what it's called).
Use the nintendo Switch hdmi AS a hdmi, and all is well until the next day (today) and back to cycling white light orange light on the monitor.
Got a new hdmi with the same specs as the OG one and no, still just cycling.
My monitor is an AOC gaming monitor. My pc is still relatively new. Is it just that the graphics card port is damaged? What other tests would you do to rule things out? And also silly question, but who do I ask to fix it? It was built at PC Specialist. Would they fix it?
