Brief description of what went wrong

Screen sizes, the ones I could measure (3840x2160 and 2560x1600) were incorrectly reported as (2560x1440 and 2048x1280) respectively.

Steps to reproduce the issue

1. Go to a computer with a monitor that has a screen size larger than 2560x1440
2. Go to mybrowser.fyi

The screen size is incorrectly reported across three browsers (Chrome, Firefox and Edge).

Any other notes

Imgur links (check image size in imgur to confirm true screen size) 3840x2160 2560x1600

2560x1440 works correctly.

Thanks for reporting this. I’ll look into it 🙂

Having a similar issue I think. It reports my resolution as being 1440px wide but my viewport as 1442px wide no matter how much I resize my browser window.

Me too: report here Please note that that my screen is not above the size mentioned in the title. Screen: 1600x900

I think this happens when I actually load the site with a small browser window. Resizing the window and then refreshing does not change the report.

The data won't change on refresh because you're looking at a report, which is a snapshot of the browser info on load 👍

Hey @gezibash, if you go to this (http://dpi.lv/), what does it report your PPI as?

[gezibash]

It's 331 ppi

[Andy-set-studio]

That'll probably explain why your screen sizes are off. A captured image will be at native resolution, but the screen will report itself @331 ppi.

A note for myself to keep an eye on #30 too.
