My GPU is Nvida Geforce GTX 1650 Super

A few days ago i bought a new HDMI cable to use an old TV as a second monitor on my pc, only to discover that my GPU only has 1 x HDMI port (already used by my monitor) and 3 x DisplayPorts.
So i went later and bought an HDMI-to-DisplayPort adapter and the first day all went well and i could use both my monitor and the tv at the same time.

However, when I turned my pc on the next day, only my main monitor had display and now my monitor only has display if i plug it on the first DisplayPort with the adapter. If i plug it in the HDMI port or any other DisplayPort, it doesnt give display after the bios screen.

The TV doesnt work as a display even when plugged in the first DisplayPort or plugging the HDMI cable in to another slot on the TV. The new HDMI cable works well, i have tried it.

Things that I have tried:
  • Removing CMOS battery and restarting
  • Starting the pc without the GPU, shutdown the pc and then connect the GPU
  • On device manager, uninstall device on the GPU and the monitors (even those that appear hidden)
  • Unninstall all display drivers using DDU

It could just be that the ports on the GPU don't work, but the TV should work as a display when it's plugged in the same place as the monitor was.

Any help is appreciated and thank you beforehand.
