Dealing with blurry images in Internet Explorer 11 can be a tricky task. The issue has several possible causes, including your browser settings, computer hardware, and even Windows 8's Web safety controls. However, with a little bit of troubleshooting and some careful attention to IE's settings, you should be able to find the cause and implement a solution.
Enable software rendering. Open Internet Explorer and press the "Alt" key to show the menu bar. Click "Tools," select "Internet Options," and then choose the "Advanced" tab. Click the "Use software rendering instead of GPU rendering" box and then click "OK" to save your changes. Check to see if the issue has been resolved.
Adjust Internet Explorer's zoom level. Zooming in or out on a website accidentally can make its images appear blurry or jagged. Press "Ctrl +"or "Ctrl -" to adjust the zoom level until the images look right.
Disable the Windows SmartScreen filter. Open Internet Explorer and click the "Settings" button. Select "Privacy" and then set SmartScreen to "Off" under "Web Services.
Reset Internet Explorer 11 entirely to clear out broken settings. Open IE, click "Tools," and select "Internet Options." Select "Advanced" and then click "Reset." Click "Reset" again and wait for the application to reset itself. Check the browser's images again after the reset.
Update your graphics card drivers. Outdated drivers could cause problems displaying websites, images, videos and more. Visit the official website of your graphics card manufacturer and look for the "Downloads" section to find appropriate drivers.
