Start Display Devices PracticeA user reports that their external monitor connected via HDMI shows a blurry image and the text is hard to read. They have tried a different HDMI cable and the issue persists. What is the most likely cause?
Explanation: This scenario tests understanding of display resolution settings. The most common cause of blurry text on an external monitor is incorrect resolution scaling, not a cable or driver issue. Adjusting the display resolution to the monitor's native resolution will usually fix the problem.
A technician is troubleshooting a monitor that displays a 'fuzzy' image with ghosting. The monitor is connected via VGA. The technician has already tried a different VGA cable and the issue persists. What should the technician check next?
Explanation: VGA is an analog signal that can be affected by electrical interference. Ghosting and fuzziness are classic symptoms of interference from nearby power cables or other electronics. Moving the VGA cable away from power sources is the next logical step.
A technician is configuring a dual-monitor setup for a stock trader. One monitor is a 24-inch 1080p display, and the other is a 27-inch 4K display. The user wants the mouse to move seamlessly between them. What setting must the technician configure in the OS display settings?
Explanation: When using monitors with different resolutions, the OS must align the virtual displays correctly. The technician needs to arrange the monitors in the display settings to match their physical layout, ensuring the mouse moves smoothly across the bezels.
A user reports that their monitor displays a 'No Signal' message when they turn on their computer. The monitor is connected via DisplayPort. The technician checks that the monitor is powered on and the cable is secure. What should the technician check next?
Explanation: DisplayPort cables can sometimes have issues with the locking mechanism or be partially unseated. The next logical step is to try a different DisplayPort cable or port on the GPU to isolate the issue.
A customer wants to connect a laptop to a 4K TV for a presentation. The laptop has an HDMI 1.4 port, and the TV supports HDMI 2.0. What is the maximum resolution and refresh rate the customer can expect?
Explanation: HDMI 1.4 supports 4K resolution at 30Hz, while HDMI 2.0 supports 4K at 60Hz. The bottleneck is the laptop's HDMI 1.4 port, so the output will be limited to 4K at 30Hz.
