Problem  

The screen resolution set by the installation process might be inappropriate for your system. This mismatch might cause screen display problems. Depending on your system hardware you can reconfigure your screen resolution during system setup. 

Solution  

After the initial Welcome screen is presented, the Installation screen is displayed. Perform the following actions: 

1. Press F2 immediately to verify that the resolution you want is selected.

2. Choose the desired resolution, then press Enter. If you choose a resolution that is above the capabilities of your display hardware the lower part of the screen is not visible during the installation. In that case, restart the installation and select a lower resolution.

3. Use the arrow keys to select Installation, then press Enter.

Only resolution values that are enabled in YaST are available in the screen resolution dialog.
