NEC has noted that some higher resolution DisplayPort signals, HDMI signals, or signals via USB-C, can occasionally become
unreliable. The typical symptom is that no image is displayed or the image is corrupted. The described OSD menu option offers
additional firmware processing for DisplayPort signals to optimize the native resolution support and therefore improve signal
reliability.
