The monitor displays a "no signal" message, despite having both male connectors in the port securely. It's been plugged into the motherboard Display port with the Intel integrated graphics as I don't have a GPU. I don't have another computer with a DP port, nor do I have another cable, so I can't really test that. I've tried installing newer display drivers, but that didn't help. The motherboard is a Gigabyte z590 Vision G and the monitor is a Samsung CT550 27".
