Meet with RDP High DPI issue

I am connected to server 2006 from Win10 notebook with a High-DPI Screen (FHD) and 125% of normal size. Text is too small and blurry when I use Full Screen. If I use other remote desktop sizes, like 800x600 or other, I get a smaller window and can’t zoom it up. What can I do to make it be full screen and clearer?

It’s not hard to find that the screen is being fuzzy and small when we RDP with high DPI to a server with lower DPI. The icons, text, dialog boxes and so on are blurry, and the process of RDP is not full screen, making it impossible to read and operate effectively.

How to fix RDP High DPI issue?

To fix the issue, we provide you with 5 ways to get you out of trouble.

Solution 1. Log off the previous device and log on the new device

Before you log onto the new device, especially for the new monitor, you’d better to log off from the previous device you have connected to before. For the changes, log off and log in can fix most of the DPI problems.

Solution 2. Check the update

Generally, checking the update is also necessary. The lower Windows version may be one of the reasons for the blurry icon and text. If the local PC and the remote PC are not at the same Windows version, then the feeling of operation must be different.

Step 1. Press Win + I to open “Settings” and locate Update & Security.
