If you're seeing garbled text or characters on your desktop computer, it can be a frustrating experience. Fortunately, there are a few steps you can take to troubleshoot the issue and get your computer back to normal. The first thing to do is to check if the acceleration function is enabled. This allows Chrome to transfer part of the graphic work to the computer's hardware, such as the graphics card, instead of forcing the browser to do all the work.
If this isn't working properly, it can cause unreadable text and characters. To fix this, simply disable the acceleration. It's also possible that your computer is not compatible with certain encoding formats. Many of the first operating systems don't support multiple encoding formats, so they may display mojibake if you try to display non-standard text.
To fix this, make sure that your operating system is localized for the country in which you're using it and that it supports the coding standards relevant to that country. If you're seeing blurry text or images on an external display device, such as a TV or projector, it could be because you're sending an image with an incorrect resolution to that device. To fix this, set the image resolution as that of the external screen. If you must use mirrored display mode, make sure that each screen works at its original resolution. If none of these solutions work, you may need to consult the Dell Knowledge Base for more information on solving display or video problems on Dell monitors.
