After connection, Samsung Dex will come up, which can help with displaying to a big screen TV.

Dex is a Samsung option that allows the smartphone to act like a standard computer on a monitor.

It will have a desktop and other options much the way a PC has.

If Dex is not used, the screen will mirror the phone screen with no changes.

Wither option works with is a personal preference for how the screen is laid out.

If the Dex option does not work for you, change the option to screen mirroring, which usually solves the issue.

Samsung Dex is not required and can be ignored if you do not want to use it.

Also, turning the phone sideways into portrait mode will display a full screen on a TV.

    I have the same issue as a few others here. Looks so simple but my phone does not have an HDMI option. I did a search in settings but it’s not there.

      It does have hdmi mode because I have a s21 as well and it’s under Settings / Connections / More Connections / Than you’ll see it. Or you can simply go to setting from your notification panel and simply search settings by typing hdmi. If you are not seeing it. Make sure your s21 has the latest system updates. If your not seeing it after that. Than you don’t have an s21 or you have a knock-off (fake) s21.

    I connected my new S21 to my TV. I have a good HDMI cord and adapter. TV set to correct HDMI port. I have no picture on the TV at all- NOTHING! I use YouTube Premium, and want to show a video on the TV.

      I would test out another HDMI cable since it is the only component that can be bad.

      I’m having the same problem and it’s not the cable.
      Did you ever find out what the problem was?

        i believe that with Android 12 update we have to enable Samsung Dex feature in Advanced features to get the HDMI working.
