Turn off "Power Saving Mode" for the Android device you're using to cast content. Enabling "Power Saving Mode" can limit the processing power of that device which could affect the performance of the Cast Screen feature.

What is CEC?
CEC, or Consumer Electronics Control, allows for HDMI devices to be controlled with one remote control. If your television has CEC support, you may be able to turn on and change the input on your TV using your phone, tablet or computer while using Chromecast. Please note that in order for CEC to work (if CEC is supported by your TV), your Chromecast must be powered by a power outlet.

Manufacturers often call CEC by different names, including Anynet+ (Samsung), Aquos Link (Sharp), BRAVIA Link and BRAVIA Sync (Sony), HDMI-CEC (Hitachi), CE-Link and Regza Link (Toshiba), SimpLink (LG), HDAVI Control, EZ-Sync, VIERA Link (Panasonic), EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).
What is HDMI?
Chromecast requires a display device that has an HDMI input, which is common in newer TVs. HDMI stands for High-Definition Multimedia Interface. Inside the Chromecast box, you will find an HDMI extender which is not required for use with Chromecast, but can be used if your Chromecast does not fit directly into your TV. It may also be used to improve your WiFi reception. The HDMI extender should be connected to your TV and your Chromecast.
