At home, I have a small home server where there are backups, shared folders, etc. So, as I logged in via Remote Desktop (since the server is running headless), I noticed that the font on the desktop icons and generally the whole appearance appeared “blurred” and changed as you moved the mouse pointer.
My first move was to check the Remote Desktop connection settings in the login window. In the Experience tab, there is a Font Smoothing option but it was already activated. That’s strange.
After a quick check on both my computer display settings and the home server, the blurry font problem remained. However, a few google searches later, the cause of the problem was found and we can now blame the anti-aliasing setting of my graphics card.
My computer’s graphics card is onboard, ie Intel HD Graphics, and it seems that the problem is “known” in this type of graphics cards. If you are facing a similar problem, the solution is to disable anti-aliasing setting in the graphics card settings.
Right-click on the desktop and then click Graphics Properties.
In the Intel HD Graphics Settings window, go to the 3D section.
Finally, click on Turn Off at the Conservative Morphological Anti-Aliasing setting and then the Apply button to save your changes.
That’s it. The blurry font in Remote Desktop Connection is restored.
