I've recently uploaded the UI to the Dwin platform, but I'm encountering an issue where the display orientation is vertical instead of the expected horizontal layout. This is affecting the overall user experience, and I need assistance in resolving it. Additionally, I've confirmed that my screen resolution is set correctly at 480×320, so I suspect there may be a misconfiguration or setting that's causing the display issue. Could you please provide me with a comprehensive solution to switch the orientation to horizontal? It would be helpful to include any specific steps or adjustments I might need to make in the Dwin settings. I'm looking forward to your prompt response, as this is critical for moving forward with my project. Thank you!
