Pixelation Problem

I'm encountering a persistent issue in Adobe Illustrator where everything I create, including vectors, text, and shapes, appears pixelated. No matter what I do, the final output is not crisp and sharp as expected.

Here are the steps I've taken to troubleshoot the issue:

1. Checked document settings to ensure proper dimensions and resolution.
2. Confirmed that anti-aliasing is enabled in preferences.
3. Reset Illustrator preferences to default settings.
4. Verified view settings and ensured I'm viewing artwork at 100% zoom level.
5. Checked document raster effects settings and adjusted resolution as needed.
6. Ensured proper export settings when saving artwork.

Despite these efforts, the pixelation issue persists and occurs consistently across different documents and projects.

Has anyone else encountered a similar issue? I would greatly appreciate any insights or suggestions on how to resolve this issue and achieve crisp, high-quality output in Illustrator.

Thank you in advance for your help!
