Monitors & displays

Text looks blurry or fuzzy on the monitor

Blurry text is usually a scaling or resolution mismatch rather than a monitor defect, especially common right after connecting a new display.

Symptoms

  • Text edges look soft, doubled, or fuzzy
  • Web pages and documents are hard to read clearly
  • Blurriness is worse on a second or external monitor
  • Text looks fine on one app but blurry in another

Likely causes

  • CommonDisplay scaling set incorrectly for the monitor sizeA 4K monitor at 100% scale, or a low-res monitor at high scale, both look wrong.
  • CommonResolution not set to nativeNon-native resolutions are stretched, which blurs text edges.
  • PossibleClearType or font smoothing turned off or misconfigured (Windows)Windows' font-smoothing tool can make small text look sharper when tuned correctly.
  • PossibleApp running in a legacy or unscaled compatibility modeCertain older applications don't scale properly on high-DPI monitors, making just that app's text blurry.

What to do

  1. Confirm the display resolution is set to the monitor's native/recommended value in Display Settings.
  2. Adjust the scaling percentage in Display Settings until text looks a comfortable size without being blurry, typically 100% for standard monitors and 125–150% for high-resolution ones.
  3. On Windows, search for 'ClearType' in the Start menu and run the ClearType Text Tuner to fine-tune font rendering.
  4. For one specific blurry app, right-click its shortcut, go to Properties > Compatibility > Change High DPI Settings, and enable 'Override high DPI scaling behavior.'
  5. Restart the affected application or the computer after changing scaling settings, since some apps need a fresh launch to apply changes.
  6. If using a second monitor with a different resolution than the main one, check that each display's individual scaling is set appropriately rather than matched to the other.

When to call a pro

This is a software settings issue, not something that needs a professional; if text remains blurry after adjusting scaling and resolution, double check the monitor supports the resolution you're using.
