You are troubleshooting a display issue in an office where an older desktop computer is connected to a monitor using a DVI cable. The monitor occasionally displays a "No Signal" message. Upon inspection, you notice that the computer's graphics card has both DVI and VGA ports, and the monitor supports both DVI and VGA inputs. Which of the following analyses BEST identifies the potential cause of the issue and suggests an appropriate solution?
The monitor's resolution might be set too high for the DVI connection; lower the resolution to match VGA standards.
The monitor might not support digital signals; switch to using a VGA cable to ensure compatibility.
The graphics card might not support dual-link DVI; check the DVI cable type and replace it with a single-link DVI cable if necessary.
The DVI cable might be faulty; try replacing it with a new DVI cable to see if the issue persists.
