Question

Can I use the USB port on my Mac?

Community Answer

The USB port will not help with an HDMI connection to your TV. You have to use the port designated for that HDMI connection.

Question

I'm hooked up and have a picture, but the picture goes blank on my TV intermittently. Why?

Community Answer

First try a different image file. Go to files then right click the image, go to properties and change the image file type. If it's a jpg/jpeg then change it to png or vice versa. If that doesn't work then see how big the image file is. If the image is 100x100 then it might be too small to display and you should try to find a larger size of the image.

Community Answer

First try to connect your Mac and your TV using a different HDMI cable. If the problem persists, it may be an issue with your HDMI port. Check to see if there are any system or driver updates available for your computer. Otherwise, you may need to repair the port on your computer.

My desktop background shows on my Roku tv when I have my Mac hooked up with an HDMI cable and the sound is transferred to the tv but the video image will not come through.

Community Answer

Ensure that you have adjusted your Screen Mirroring settings so that you are mirroring your display and not extending it.
