Screen resolution looks wrong or blurry

Symptoms

• Text and icons look fuzzy or pixelated
• Desktop doesn't fill the whole screen, with black bars around it
• Icons and taskbar appear too large or too small
• Resolution option is missing the monitor's correct native setting

Likely causes

• CommonDisplay resolution set below the monitor's native resolutionEvery monitor has one 'native' resolution that looks sharpest; anything else is scaled and blurry.
• CommonOutdated or generic graphics driverWindows may fall back to a generic driver that doesn't list the monitor's full resolution options.
• PossibleWrong cable type limiting resolutionAn older VGA or low-spec HDMI cable can cap the maximum resolution the monitor can display.
• PossibleMonitor not properly identified by the operating systemA generic 'Plug and Play Monitor' listing often means the OS doesn't know the correct native resolution.

What to do

1. Right-click the desktop, choose Display Settings, and look for a resolution labeled '(Recommended)', which should be the native resolution.
2. If the recommended resolution looks wrong or blurry anyway, check the monitor's specifications (often printed on the back or in its manual) for the true native resolution.
3. Update the graphics driver from NVIDIA, AMD, or Intel's website, or via Windows Update, then recheck the resolution list.
4. If using an older VGA or low-bandwidth cable, switch to HDMI or DisplayPort if your ports support it.
5. On Windows, also check Settings > System > Display > Scale to make sure text scaling (100%, 125%, 150%) isn't set unusually high or low.
6. Restart the computer after changing the driver or cable, since some resolution options only appear after a fresh detection.

Tools and parts

• None

When to call a pro

If the native resolution still isn't offered after a driver update and a known-good cable, the monitor's EDID chip (which reports its specs) may be failing, which usually needs a technician or manufacturer support.
