Use this solution for incompatible theme dimensions:
The DE Best Practices Guide (PD24868) recommends that you leave the default options on the Theme tab for easier deployment and management. After you've successfully deployed the default theme, change the DE policy at the ePO console to deploy the custom theme.
Create a new custom theme using the following custom theme requirements:
- Image dimensions: 1024 x 768
- File format: .PNG
- File size: approximately 600 KB
Allow the theme to replicate to distributed repositories before attempting to update the DE clients.
After creating a custom theme, to avoid a common theme deployment mistake, follow the advice documented in
KB84807 - Failed to unzip new theme file (custom theme not displayed at preboot when Product Update task not run), where the preboot custom theme isn't displayed because a product update task wasn't run.
For details about creating a custom theme, see the relevant DE or EEPC Product Guide.
