Question
I'm experiencing a visual issue with Tizen TV models from 2014 and 2015.
The problem occurs when:
- I set a full-screen background image using CSS (properly sized for the resolution)
- Place a white div element on top of this background
- Notice white bands appearing on the left and right edges of the white div
- The wider the white element, the more prominent these bands become
I've tried various layout approaches but haven't found a solution that eliminates this artifact.
Answer
Problem Understanding
This appears to be a known rendering issue specific to earlier Tizen TV models (2014-2015). The problem manifests when displaying white UI elements over dark background images, causing unwanted visual artifacts at the edges.
Solution Methods
-
Use Background Color Instead of Image
- Try replacing the background image with a solid color background
- This often eliminates the rendering artifacts completely
-
Apply CSS Blend Modes
- Experiment with different blend modes for the white element:
.white-element { mix-blend-mode: screen; /* or try other blend modes like overlay, lighten, etc. */ } -
Add Padding or Margin
- Increase the padding/margin of the white element to move it away from screen edges
- This can sometimes minimize the visibility of the artifacts
Additional Tips
- This issue is specific to older Tizen TV models and has been resolved in newer versions
- Consider testing your application on newer Tizen TV models if possible
