The Amazon Fire TV voice remote has some undocumented tricks up its sleeve. If you aren’t aware, holding SELECT and PLAY for 10 seconds causes the Fire TV to restart. Similarly, holding RIGHT and BACK for 10 seconds triggers a prompt to factory reset the Fire TV. These hidden options seem to be designed to help you get back to a usable state if, for whatever reason, you are unable to access the Fire TV’s menus. Yesterday I stumbled on some new hidden resolution options triggered from the voice remote.
If you hold BACK and REVERSE and RIGHT and SELECT simultaneously for 10 seconds, the Fire TV will begin to cycle through various resolution settings. It will stop at each setting for 10 seconds and cycle to the next option if you do not press SELECT. Pressing SELECT will save the current display setting. This can be useful if somehow your Fire TV is set to a resolution that your TV doesn’t support.
Interestingly, using this hidden option allows you to select 480p even though the option is not available in the Video Resolution options found in the Settings menu. When 480p is selected, it will appear as the current setting, but it will remain missing from the available resolution options in the settings menu. One thing worth mentioning is that I believe the Fire TV is always rendering at a resolution of 1920 by 1080 regardless of what resolution is selected and just downscaling the video output. I think this is the case because taking a screenshot of the Fire TV results in a 1920 by 1080 file no matter what resolution is selected in the options menu.
For the final version of Fire OS 5, the button combination to bring up resolution cycling has been changed to holding REVERSE and UP
