# Can't Zoom In/Out with the mouse wheel in TruView LIVE in a Chrome browser

### **Description**

In Chrome, scrolling the mouse wheel in the viewer doesn’t do anything. It’s not possible to zoom in or zoom out.

### Probable Cause

The number of lines to scroll with the mouse wheel must be ‘3’; otherwise, the mouse wheel doesn’t work correctly.

### Solution

To change the mouse settings:

1. Press the Windows key. Type ‘Mouse Settings’.
2. The Mouse Setting dialog will open.
3. Choose ‘Multiple lines at a time’.
4. Slide the horizontal scroll bar to ‘3’.
