I recently bought a macbook pro 16 inch m2 but the usb-c to displayport won't show any signal after connecting the usb-c end to the macbook and displayport into my alienware aw3423dw. Does anyone know why this is happening? the specific cable I am using is linked below.
Hi Bao Long Speedy,
Thank you for using the Apple Support Communities! To connect a display to your Mac, you'll want to confirm the steps below:
Connect the display to power and your Mac
1. Use your display's power cable to connect the display to power.
2. Use your display's video cable to connect the display to your Mac, such as to a Thunderboltor HDMI port. Different ports might look similar, so it's important to identify the port correctly.
3. If the video cable requires a port that your Mac doesn't have, you might be able to use an adapter with the video cable. Or replace the video cable with one that doesn't require an adapter.
4. When your display has power and is connected properly, your Mac detects the display automatically. You should then see your Mac desktop on the display, and you can configure display settings.
If your display isn't detected or can't use its highest resolutions or refresh rates, learn what to do if your display has a dark screen (no video) or low resolution.
Hope this helps!
Have a great day.
