Changing the Menu Resolution
When we ship our devices, they are set to 720p resolution, one of the most common HDTV formats supported by essentially every television made in the past decade. However, some AV systems prefer lower resolutions and some people prefer to get the maximum out of their device by setting it to a higher resolution like 1080p. Our menus are created to support any 16:9 ratio resolution like 720p (1280x720) or 1080p (1920x1080) but they can support other resolutions upon request.
Changing the Resolution
The first step is to find a USB keyboard and mouse so that you can control the device. When the device boots up, click the configuration button and you should see a screen like this one where you can set the WiFi, change the orientation or in this case change the resolution. The list of resolutions is read from the resolutions the TV that the device is hooked up to supports and so the list of resolutions may not be the same as the one in this screenshot. You can select a resolution and click save. After saving, a reboot button will appear and you will need to reboot to see the new resolution.
Note: The "Auto" resolution will read the supported resolutions when the device boots up and choose one. If your TV is off when the device boots up, no available resolutions are seen and it will default to a really low resolution until it is rebooted.
Note: If you set your resolution to something like 1080p (1920x1080) and you later hook the device up to a TV that does not support that resolution, you may have to hook it back up to a TV that supports 1080p resolution and set the resolution back to something lower (like 720p) before hooking it back up to the other TV.
