I'd verify using an alternative cable first. HDMI employs specific pins to identify and exchange resolutions that both the graphics card and monitor can handle. If the cable is faulty, you might notice a disruption in this exchange, causing the card to attempt a resolution it thinks the monitor can support. Should another cable fail, it likely points to the monitor, as the problem continues between the PC and PS4, suggesting a repair or return merchandise authorization process.
