Question 441 - 220-1101 discussion

The most likely cause of the issue is C. Physical cabling issues.

Physical cabling issues can affect the quality and stability of the display signal. If the cable is loose, damaged, or bent, it may cause intermittent connection, interference, or signal loss. This can result in slow, distorted, discolored, or blank display.

To troubleshoot physical cabling issues, the user should check the following steps:

• Make sure the cable is firmly connected to both the display and the video adapter.

• Inspect the cable for any signs of damage, such as cuts, frays, kinks, or exposed wires.

• Check the cable connectors for any bent or broken pins.

• Try a different cable or a different port on the display or the video adapter.

• If possible, test the display with another device or test another display with the same device.

The other options are less likely to cause the issue, because:

• Incorrect data source may result in no display or an error message, but not slow or distorted display.

• Incorrect resolution settings may cause stretched, blurry, or cropped display, but not discolored or blank display.

• Incorrect refresh rate may cause flickering or tearing display, but not slow or distorted display.

• Display burn-in may cause permanent image retention or ghosting on the display, but not intermittent or blank display.
