The monitor won't show anything through the display port unless another signal is active.

This seems to be the last update since performance on the monitor has deteriorated. I attempted to use DisplayPort from my older PC (GTX 1050Ti), which previously worked, but now it fails completely—shows no image, then hangs with a no-signal alert before shutting down repeatedly. Until I force a power cut, it suggests the cable may be faulty, the connector is damaged, or the monitor’s DisplayPort module has failed. As discussed earlier, this screen will likely be taken over by a backup unit once a replacement arrives.
