A user has installed a new USB port replicator for use with their notebook PC. When the replicator monitor port is connected to a monitor, the monitor will only display at its lowest resolution. Which of the following is the MOST likely cause of this issue?

Question

Accepted Answer

C. The drivers for the port replicator may not be current. Port replicators include hardware that translates USB signals to video output, requiring specific drivers to enable full resolution support. If those drivers are outdated or not properly installed, the device falls back to a generic low-resolution mode. Updating the port replicator drivers restores full resolution capability to the connected monitor.

Answer

A. The monitor self adjustment control must be configured. Monitor self-adjustment (auto-sync) corrects image centering and geometry, not the maximum supported resolution.

Answer

B. The monitor is failing and needs to be checked by a technician. A failing monitor would show distortion, flickering, or no image - not a consistent low-resolution output tied to a new device.

Answer

D. The notebook BIOS is not current and must be updated. Notebook BIOS updates affect hardware initialization and compatibility at the firmware level, but do not control the resolution output of an external USB port replicator.
