Hi @osterek,

Welcome to the Sony Online Community! To prevent the TV from entering into screen saver mode follow these steps:

1. Find and highlight the option under [HOME] > [Settings] > [About] > [Build]
2. Press the [OK] button on your remote control 7 consecutive times to activate the Developer Mode
3. Find and enable the option under [HOME] > [Settings] > [Developer options] > [Stay awake]

Your TV won't enter screen saver mode, effectively bypassing the settings in your screenshots. If by any chance you would want to deactivate the Developer Options from appearing in the Settings menu you will be required to simply disbale the option under [HOME] > [Settings] > [Developer options] > [Enable Developer options].

Hope you find that useful.

Cheers,

Dutchice
