HDMI not working

My Desktop PC can’t get a picture on my monitor. I have confirmed that it is not a problem with the monitor itself, as it works with other devices. I was able to use the PC with the screen fine just this morning, but now the signal won’t come through. My PC has a GTX 1070ti with the hdmi output that has the screws in it. I have tried plugging a different kind of hdmi into the card, restarted the pc countless times, tried a different monitor, plugged an Xbox into my current monitor (which worked), changing the monitors settings, cutting power to everything and restarting it, and using both hdmi 1 and 2. Please help.
