PC randomly stopped displaying to my TV

[spamcan]

I have used my VIZIO TV for quite some time now as a second display, but only recently has it stopped working. I tried moving some cords around and have found out that one of my HDMI ports, the one my TV was plugged into, may be damaged. that HDMI port does not display anything to my TV or my main monitor. But the weird thing is, when I plug my TV into the working HDMI port (main monitor is using rn), it doesn’t display anything either. But I have tried plugging another monitor into the working HDMI port and it displays properly. Is the issue my TV, GPU, or both? I’m going to get a DP cable for my main monitor but that wouldn’t even solve my problem because my PC doesn’t display to my TV when it’s plugged into the only working HDMI port. This situation is very confusing and I would like some advice on why it stopped working suddenly and how to get my TV working as a second display again. Below is more misc information I have found out to help solve this situation. -

• My switch displays perfectly fine to my TV with the same HDMI cable and port on my TV
• drivers are all up to date.
• the main monitor does not work in the seemingly damaged HDMI port
• TV does not connect to the working HDMI port
• another monitor doesn’t connect to the damaged HDMI port

I have used my VIZIO TV for quite some time now as a second display, but only recently has it stopped working.

Does it work when connected to any other devices, a notebook or used as a standard TV.

Golden rule when asking for help on tech forums, post as much information about the PC and/or associated hardware as you can, no one can help you when knowing zero about your computer etc.

Sorry about that, that totally slipped my mind. here are my specs:

• GPU: NVIDIA Geforce GTX 1060 3gb
• CPU: ryzen 5 3600
• MotherBoard: ASUS prime B450 plus
• RAM: corsair vengeance pro X2 8gb 3.2ghz
  and my main monitor is an acer ED273 and my TV is a VIZIO D32hn-E0
  Also, to answer your main question, my TV does work as a standard TV and also displays my Nintendo switch. I am unable to test any other devices besides the cable box and my switch.

Based on the symptoms and the additional info you could be 100% correct in that the GPU has a bad HDMI port, two things that you mention suggests that there could be something else going on;

The TV works fine as a TV and your Nintendo.

The TV does not work when connected to the known good HDMI port.

Missing from your list of specs are the PSU details, post the brand and model name or number + how old the supply is.

my PSU is the ASTRAPE M1 750B 80plus bronze psu and its around 3 and a half years old, which is the age of my GPU and motherboard as well.

ASTRAPE M1 750B 80plus bronze

Rated as Tier D • Recommended only for very cheap, iGPU systems here this basically means that the PSU should not be used anywhere near an add on GPU.

oh okay, I see. thank you for your help!

See if you are able to borrow a known good 500W or above Bronze efficiency rated PSU from either EVGA or Seasonic, both of these brands are capable of supporting your GPU being that it is an older card.

You are welcome btw
