What is my screen resolution?

Everything this device says about itself.

100% LocalFree

Everything above was read from your browser on this device and stays here. Nothing is sent anywhere, which is also why a few values say not reported: browsers keep some details back, and this page does not go looking for them.

How to read the report

  1. 1 Screen resolution is the whole screen in the units the operating system uses. The browser window is the part this page can draw in, which is smaller and changes when you resize or open a sidebar.
  2. 2 Pixel ratio explains the gap between the two. On a scaled or high-density display, one reported pixel covers two or more real ones, and physical pixels is that multiplication done for you.
  3. 3 Copy the report when you need to tell somebody what you are working with. It is plain text, so it pastes into a support ticket without turning into an attachment.
  4. 4 The graphics line is what your browser is willing to disclose. Some browsers give the exact model, others give a generic name or nothing at all.

Frequently asked questions

Why does the resolution here differ from my display settings?
Because of display scaling. At 150 percent scaling a 3840 by 2160 screen reports 2560 by 1440, since that is the space software actually lays out in. The physical pixels line gives the number your settings show.
Why is the window smaller than the screen?
The window excludes everything outside the page: the browser toolbar, the taskbar, scrollbars and any sidebar. It is the number that matters for a web design; the screen resolution is the number that matters for a wallpaper.
Can you see this information about me?
No. The values are read in your browser and rendered on your screen. The page has no server to send them to, which is worth saying because most pages that show this list do collect it.
Why is memory or graphics missing?
Both are optional. Firefox and Safari report memory not at all, and browsers with fingerprinting protection often mask the graphics card. Missing here means withheld by the browser rather than absent from the machine.
