# High DPI issues

There are multiple problems that can be caused by high DPI in RDP sessions, the most commons are the following:

* RDP connections are tiny
* RDP connections are big
* RDP connections always have a scroll bar
* Remote Desktop Manager is blurry
* 4K resolution issues

### Solution

There are multiple methods on how to solve these issues.

#### Method 1

1. In Remote Desktop Manager, go to ***File – Settings – User interface*** and change the ***Display scaling*** to ***DPI unaware***. If you cannot see the setting because of display issues, you can add the line in your config files directly.

{% hint style="info" %}
To locate your config file refer to [Configuration file location](https://docs.devolutions.net/rdm/installation/client/configuration-file-location/).
{% endhint %}

2. Once you have found the right folder, open **RemoteDesktopManager.cfg** with your preferred text editor.
3. Under the line `XXXX-XX-XXT00:00:00-00:00`, change the ***Default*** to ***None*** and save.
4. Restart Remote Desktop Manager.

#### Method 2

1. Close Remote Desktop Manager.
2. Right-click on your Remote Desktop Manager icon.
3. Go to ***Properties***.
4. In ***Compatibility*** tab, click ***Change high DPI settings***.
5. In ***High DPI scaling override*** section, check ***Override high DPI scaling behavior*** and click OK.
