The technician confirms that the appropriate HDMI cable is plugged into the user's computer and the TV has a blinking logo on the screen Which of the following is most likely causing the issue?

AThe user's laptop does not support screen mirroring

BThe television does not support screen mirroring

CThe wrong input is selected on the television.

DThe user does not have Bluetooth enabled on the laptop.

EThe television has a defective A/C adapter cable.

Show Suggested Answer

Suggested Answer: C

When a laptop screen fails to mirror to a television despite being correctly connected via an HDMI cable, a common issue is that the television is set to the wrong input source. Modern televisions have multiple input options (e.g., HDMI 1, HDMI 2, AV, etc.), and selecting the correct input that corresponds to the port the HDMI cable is connected to is essential for displaying the laptop's screen. The blinking logo on the TV screen typically indicates that the TV is functioning but not receiving a signal from the selected input source. Changing the TV's input to the correct HDMI port should resolve the issue and allow the laptop screen to mirror onto the TV. Reference: Hardware 1101.docx, 'Connecting External Displays' section.

Good point, Stevie. But if that were the case, wouldn't the TV just show a blank screen, not a blinking logo? I think the blinking logo indicates the TV is detecting the signal, it's just not set to the right input.

Hmm, I'm not sure. What if the laptop just doesn't support screen mirroring? I've had issues with that before, where the HDMI connection works, but the laptop can't actually mirror its display.

I agree with Theron. The wrong input on the TV is the most logical explanation here. The technician said the HDMI cable is plugged in, so it's probably just a matter of selecting the right HDMI input on the TV.

This question is a bit tricky, but I think the most likely issue is that the wrong input is selected on the television. The blinking logo on the screen suggests the TV is detecting an HDMI signal, but it's not displaying the laptop's screen properly.
