- Powering up your Player without a screen connected.
- Powering up your Player and screen at the same time (e.g. after a power failure). If you screen is slow on startup, it does not report it's resolutions in time to the Player.
If you are having constant issues like this, then you have two options for a permanent solution:
- Set the resolution of the Player to a standard one. Your Player will always use this resolution, regardless if you have attached a screen or not, or if the attached screen supports it or not.
- Increase the time the Player waits for detecting the screen. This delay is by default to 3 seconds. You can increase it, to allow your screen to properly start and allow the Player to detect it. To do this: 1) go to your Monitor entry in the Yodeck Portal, 2) go to the "Advanced" tab, 3) make sure the "Allow Raspberry config.txt Override" toggle is set to "ON", 4) add the following line to the "Raspberry config.txt Override Directives", using the number of seconds that works for you:
5) make sure you click the "Save" button, so that the configuration you did is saved.
