Question Monitor won't recieve any signal from GPU, not sure which part is causing it.

So just built a new PC, and everything was working fine until my monitors stopped receiving input from my GPU(GeForce RTX 2060). After plugging my specs into pcpartpicker, I got a note saying that my motherboard (Asus ROG Maxiumus XII Hero) had an additional 4-pin ATX connector that my PSU (Corsair RM550x) did not, and that it would be necessary for overclocking and larger GPU current draws. I feel like that may be the issue here, but I've seen many posts saying that the 4-pin connector is only necessary for heavy-duty overclocking, so I'm not sure. Do I need to find a replacement cable to fit the 8+4-pin connector, or is something else the issue?

Hello, it will be great to have a full list of components, including brand and model of the GPU and PSU.

What have you tried soo far?,

Are video and power cables tight enough (firmly plug) on the back of the monitor and the PC?,

Different video cables, different ports on the GPU, different ports on the monitor, PC into the TV?

Here's my parts list: https://pcpartpicker.com/list/CB7C3Z

So far I've tried:
  • Plugging the GPU into different PCIE ports on the motherboard
  • Changing out the HDMI cables
  • Using DP cables instead of HDMI
  • Reinstalling drivers
I know that the problem isn't the monitors or HDMI cables, since they both display fine when plugged directly into the motherboard.

If thats the case then there are a few things to try:

  1. See what Qled and Error code your motherboard show.... Or.....
  2. Clear CMOS using the button.... Or...
  3. Test your GPU on a differnte PC (always use the top PCIe port).
I think this is your mobo manual: https://dlcdnets.asus.com/pub/ASUS/mb/LGA1200/ROG_MAXIMUS_XII_HERO_(WI-FI)/E16575_ROG_MAXIMUS_XII_HERO_WI-FI_UM_V2_WEB.pdf
