This is a great value monitor for getting the full desktop experience out of your Raspberry Pi.
The 21.5" full-HD screen is LED backlit, lowering power consumption and your energy bill at the same time.
The screen features built-in speakers with an optional line in/out for external speakers/headphones, a HDMI and VGA port to the rear, and VESA mounting points - great for our Raspberry Pi VESA case.
A HDMI cable is included in the box which will plug straight into a Raspberry Pi 3/3A+. Combine with a mini-HDMI adapter to use with a Raspberry Pi Zero. To use this screen with a Raspberry Pi 4, you'll need a micro-HDMI cable - available here.

HE225HPB Datasheet
You power on via power button. It will then display its HDMI input. In the absence of activity on HDMI it will fall asleep. Activity will wake it up. May be able to change this but haven't tried. Hope this helps
