My screen resolution is actually 3200x1800, but when I'm in a browser it acts like I have a smaller resolution. How do I get my browsers to use my full resolution?

On Chrome it's using 1280x720, and on IE it's using 1600x900. According to whatismyscreenresolution.com, which is showing different values for different browsers. I took a screenshot of them and verified that my resolution is 3200x1800 as that is the pixels in the bitmap.

I'm on a laptop with no monitor plugged in. My zoom in both browsers is at 100%. I've tried zooming out below 100% but then the text is unreadable and pixellated. I've tried restarting. Windows 8.1. I've tried the chrome extension OptiZoom and it does nothing. document.body.clientWidth gives 1247, and I want it to give 3200.

Possible Problem

This is most likely an issue caused by Window 8.1 "Display Scaling" feature. See a relevant post in the Google Chrome forum.

Possible Solution

Try disabling this feature for your browsers. For example, locate the Chrome executable which is commonly found in %ProgramFiles(x86)%/Google/Chrome/Application/. Right click the file, select "Properties" and then under the "Compatibility" tab tick the box saying "Disable display scaling on high DPI settings"

Well, it’s pretty obvious this is yet another example of DPI scaling gone horribly wrong.

Chrome is party to blame too. According to this article, there are (well, were) some possible workarounds.

  • Disable DPI scaling in Chrome’s compatibility settings (Properties on executable or shortcuts)—last resort “solution”
  • Go to chrome://flags and enable experimental Windows HiDPI support. (Gone now, apparently)
  • Load the following .reg file:

    Windows Registry Editor Version 5.00

A word of warning though: HiDPI is under development and has issues. If you cannot live with that, I suggest you try an alternate browser like Firefox. It’s supposed to have better DPI scaling support.


For those who are using Windows 10,

  1. Go to Start button > Settings > Ease of Access > Display.
  2. Set "Make everything bigger" to 100%.

See here the screenshot of above Settings page.

(Note: However keeping it to recommended settings gives you more readable texts across different applications.)


Remember that display resolution is configurable, it's different from native resolution.

Another better choice is http://myscreenchecker.com, not only check for screen display resolution, but also for checking your screen color, screen health with 15 basic color, including: black, white, red, green, blue, ...
