Screen & Display
Metrics
Sites read your screen size, pixel ratio and color settings to tell devices apart. This page shows those values live, so you can check that a profile looks like a real display.
Everything runs in your browser. Nothing on this page is sent to XProxy or anyone else.

What this check means
What websites read
screen.width, screen.height, availWidth, devicePixelRatio and colorDepth are available to every script with no prompt. Resolution is one of the most common values used to group visitors and it is part of every browser fingerprint.
Why antidetect browsers change it
A profile that pretends to be another computer needs another screen. Antidetect browsers override these values, but if the window keeps its real size the numbers disagree: the viewport can end up larger than the screen.
Typical mismatches
A 1920×1080 screen with a 2560-pixel-wide window, an available height larger than the full height, a mobile profile with a 1440-pixel-wide screen, or a pixel ratio of 1 on a profile that claims to be a recent iPhone.
How to fix it
Use real resolutions of the device you copy (1920×1080, 1366×768, 1440×900, 390×844 …), keep the window smaller than the screen, and set the pixel ratio the way that device does. Resize this window and watch the values update.
Questions
What is the device pixel ratio?
It is how many physical pixels make up one CSS pixel. Most laptops report 1 or 2, phones 2 to 3. Browser zoom changes it too: 200% zoom reports 2.
Why is my screen bigger than my window?
The window is just a part of the screen, so that is normal. Only the opposite, a window that is larger than the screen, is suspicious.
Why do the values change when I zoom?
Browser zoom changes the size of a CSS pixel, so the viewport and the pixel ratio change, and in some browsers the screen size in CSS pixels too. Sites compare these values, so keep zoom at 100% in your profiles.
Same device story on the network side
A believable screen is one signal. XProxy mobile proxies give your profiles real carrier IPs, so the network fits the device you present.
