Fix thisWhat is this?
Every browser exposes the pixel dimensions of your screen (window.screen.width and height), the color depth, the pixel density (devicePixelRatio), the OS platform (navigator.platform), and whether you have a touch screen (navigator.maxTouchPoints). Websites use these values for legitimate reasons -- picking the right image resolution, deciding whether to show a mobile layout -- but the same values are also the top three contributors to a browser fingerprint, right up there with fonts and canvas rendering. A specific combination like 3840x1080 at 1x with Win32 and no touch is unusual enough that it narrows the room of potential users you could be by a huge factor.
So what?
Fingerprinting is how ad networks and fraud-detection systems track you across sites even when you clear cookies and use private browsing. Your IP might rotate, your cookies might reset, but your screen resolution + platform + touch capability rarely change from one session to the next. That is why hardened browsers like Brave, LibreWolf, and Tor Browser deliberately misreport these values -- they clamp the resolution, force devicePixelRatio to a common value, and lie about touch support so every user on that browser looks the same to fingerprinters.
Now what?
You are running a browser that misreports these values on purpose (Brave with Shields on, or similar). The resolution and DPR the browser is showing here are decoys, not your real hardware -- that is a good thing. No action needed. If you want to go further, install the Tor Browser for maximum-risk sessions (research, journalism, whistleblowing) where the extra latency is worth the near-perfect anonymity.
Your browser is faithfully reporting your real screen resolution, platform, and touch capability. If fingerprint resistance matters to you, the best moves are: (1) Switch to Brave (Chromium-based, one-click install, misreports screen + hardware values by default). (2) Switch to LibreWolf (Firefox fork, aggressive privacy defaults, no telemetry). (3) In Firefox, set privacy.resistFingerprinting to true in about:config -- this forces a standard 1000x1000 window size and rounds DPR. AVOID relying on Chrome or Edge alone for fingerprint resistance: they expose everything and have no equivalent setting. AVOID Safari on macOS for the same reason -- it exposes a very specific and stable set of values that fingerprinters love.
If fingerprint resistance matters, switch to Brave, LibreWolf, or Tor Browser. Chrome, Edge, and Safari expose these values with no way to hide them.
