Question #: 27
Topic #: 2

A technician has been called into a conference room to help with a video call setup. The user is unable to get the laptop screen to mirror to the in-room television. 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.

Haha, can you imagine if the problem was that the user forgot to turn on Bluetooth? That would be the most embarrassing tech support call ever. 'Did you try... turning it on and off again?'

I dunno, guys. What if the laptop just doesn't support screen mirroring? That would be a real bummer. But I guess we can rule that out since the technician is already on the case.

Yeah, that's a good point. I'm leaning towards option C - the wrong input is selected on the television. The technician confirmed the HDMI cable is plugged in, so it seems like the TV just needs to be switched to the right input.

Hmm, this is a tricky one. I'm not sure if the issue is with the laptop or the TV. The blinking logo on the TV screen makes me think it's trying to detect an input signal, but can't seem to find one.
