Hello Cenk,
Thank you for your message.
The name of the Viewer's machine that is displayed in the
Notification panel is determined by the
Device name that is set up on the Viewer's side. It's possible to rename the computer though, so the displayed name in the notification panel is more accurate.
In order to do so, please do the following:
1. Open Windows Settings (simply press
Win+I shortcut on your keyboard) and select
System section.
2. Navigate to the
About tab in the left section of the window.
3. Scroll down to the
Device specifications section and select
Rename this PC.
This should change the computer's name displayed in the notification panel.
Please note that the above instruction is meant for Windows 10, so if you use another version of Windows the steps might slightly vary.
Hope that helps.
