9. User Tips

• Optimal Viewing Distance: For best visual clarity of images and text, view the curtain lights from a distance. Close up, individual LEDs may make patterns less distinct.
• Text Readability: When creating custom text, using capital letters can significantly improve readability due to the pixelated nature of the display.
• Image Limitations: While the app offers extensive customization, some complex images or very detailed text may have limitations in definition due to the LED resolution.
• Outdoor Use: The product is certified for indoor holiday use (LIVING ROOM, Valentie's Day, Wedding, Birthday). There is no explicit rating for outdoor weather resistance (rain or sun exposure). It is recommended to use them in sheltered outdoor areas or indoors.
• Customization: The app allows for DIY patterns and text. While you can draw your own designs, direct upload of any image from the internet is not a stated feature.
• Controller Customization: Some advanced users have modified the controller for custom setups, but this voids the warranty and requires soldering skills.
