it sounds crazy but find a cable that actually has the official stamp from the industry group that rates hdmi/displayport cables. it actually makes a huge difference!It probably helps explain issues I've had with flickering, static, and outright loss of signal trying to play or even just start games at 4K. The cable I've been using is likely from when I built this PC's predecessor. In 2011. Beyond time to upgrade.
