Getting the display screen resolution

[Chethiya Abeysinghe]

Hi Devs,

Is there a way to get the screen resolution of the computer display? 

Thanks

With standard javascript

window.screen.availHeight
window.screen.availWidth

All properties:

availHeight	Specifies the height of the screen, in pixels, minus interface features such as the taskbar in Windows.
availWidth	Specifies the width of the screen, in pixels, minus interface features such as the taskbar in Windows.
colorDepth	The bit depth of the color palette available for displaying images in bits per pixel.
height	The total height of the screen, in pixels.
pixelDepth	Display screen color resolution (bits per pixel). Firefox exclusive property.
width	The total width of the screen, in pixels.

Hi Chris,

Thanks for pointing that out. Really a life saver for what I'm planing to do. It works in the browser action popup.

Can anyone recommend how to make "window" available in the service_worker for MV3?

[Stefan Van Damme]

Hi @nors...

The Chrome extension (in Manifest V3) service worker can not have access to the DOM.

A workaround is to try running your window.screen.availHeight code in your content script, and then send the message back to your background service worker.

Or you can use this code:
https://developer.chrome.com/docs/extensions/reference/system_display/

With chrome.system.display.getInfo() you can get the current screen width and height.

Thanks,

System.Display cannot be used normally - https://bugs.chromium.org/p/chromium/issues/detail?id=1303129&q=&can=4
