If it indicates "No display connected", there may be two applicable situations.
If this is a laptop or all-in-one (AIO) PC (computer integrated into display chassis):
Laptop displays are not connected to their dedicated GPUs, instead using the integrated GPU on the CPU. If your laptop model has a MUX switch, you can use it to bypass the iGPU. If it does not, you'll have to make the adjustments you want in your iGPU's control panel instead ("Intel Graphics Command Center" / "AMD Software: Adrenalin Edition"). Some higher-end gaming laptops may expose Advanced Optimus settings in the NVIDIA App, too.
AIO PCs are usually built similarly to laptops, and the same applies to them.
If using external displays for some laptops, it may be possible to still bypass the display output by having it go through a video port that is wired directly to the dGPU. You can check if this is the case by going to NVIDIA Control Panel > Configure PhysX, where a display topology will be shown. If there are any video outputs wired directly to the dGPU, they will be shown here within the box of your dGPU.
If this is a desktop PC:
Make sure all of your monitors are connected to the ports of your graphics card, not to the motherboard. If you are unsure or don't know what this means, take a picture of the back of your PC and send it into this channel.
