I got this adaptor for outputting video from the Apple laptop's USB-C port to a TV's HDMI port but some of the time the video output just refuses to appear on the TV screen. Don't know why this happens every now and then. So I regard this as a reliability issue. Maybe the adaptor has a poorly manufactured or faulty pins in its USB-C plug? What options do I have for resolving this issue by Thursday next week (01 May)? The product has a two year warranty.

Thanks in advance for your assistance with resolving this issue.

Take it back to where you bought it for warranty.

I bought a tech inc. product (usb-c to microUSB with lightning and usb-c end adapters) on a whim about a year ago for about $20, and holy shit that thing never worked right out of the box. The end ports would get really hot, close to burning temp. The adapters were also a struggle, and felt like they're about to break everytime its put on or off.

I honestly expected better quality for such a generic product, especially for that price. So lesson learned and just buy the quality items, even for the small stuff like this because the expectancy difference is significant.

Thanks, bought the USB-C to HDMI CDP2HDMM2MH adapter and it works well :).

However, had a major piece of misfortune last month. My MacBook’s screen was water damaged on the night of Thurs 5?June when torrential rain fell down that night which must have penetrated my briefcase and got into the screen’s internal electronics.

Now the internal screen won’t show anything.

For some time I was able to show the laptop’s output via that reliable adapter to my TV till I inadvertently turned on mirroring which stopped output from showing on my TV to my frustration. What can I do about that? Try showing output on another large monitor? Or something else?

I was told that there’s a $500 excess under my contents policy to repair or replace the internal screen.

I need to be able to show PowerPoint slides (I have the PowerPoint slideshow files) to students on a large monitor when I resume community education teaching work in the week starting Mon 21 July.

What options do I have for getting suitable hardware to show the PowerPoint slideshows on a large monitor again? Leasing a PC laptop? Renting it? Borrowing it? Getting the repair of my MacBook screen completed? Photograph the slides with my iPad, connect it to a large HDMI compatible monitor with a suitable output cable? The USB-C to HDMI adapter I have won’t plug into my iPad.

Thank you for any help you can give me there.

Isn't there a hotkey you can use to change the screen mode?

Command - F1 swaps it between mirroring / extending on my MacBook Air.
