Frequently Asked Questions
What's the difference between screen resolution and window size?
Screen resolution is your display's full pixel count. Window size is your browser's current dimensions, which is smaller when not maximized or when toolbars/taskbars take space.
What is Device Pixel Ratio?
Shows how many physical pixels equal one CSS pixel. 2x means Retina/HiDPI display with 4x the pixels (2× width, 2× height). Higher DPR = sharper text and images.
Should I use native resolution?
Yes! Always use your display's native resolution for sharpest image. Scaling to non-native resolutions causes blurriness. Adjust font size/UI scaling instead if things are too small.
Why does my resolution look wrong?
Check display settings in Windows/Mac. Update graphics drivers. Ensure proper cable connection (some HDMI versions limit resolution). Try different port if available.
