Why My External Monitor Was Blurry—and How I Fixed It
1 min read
Summary
A common cause of a blurry monitor is a loose or improperly connected HDMI cable, so ensure it is properly connected to both ends.
The cable itself might be the issue, especially if it is old or generic, so check if it supports your monitor’s required resolution and refresh rate.
Restarting both your computer and monitor can resolve temporary glitches or configuration issues.
Setting the correct display resolution and scaling is crucial, as your monitor has a native resolution that matches the number of pixels it can display.
Scaling adjusts the size of elements on the screen, and if it is not set correctly, elements can appear blurry.
Windows often recommends the ideal resolution and scaling settings, which you can access and apply.
Manually adjusting these settings to match your monitor’s specs closely can also help.
A tool built into Windows, the ClearType Text Tuner, can improve the appearance of text.
If Monitor Drivers are outdated, updating or reinstalling them could fix the issue.
This can be done via the Device Manager, where you can also unistall the driver if it is corrupted.
