MAC36 - HDMI Panels - Optimizing graphics performance on MAC36 with HDMI display

Introduction

The issue involves performance discrepancies when using the MAC36 with an HDMI output compared to an Android panel over Ethernet. The core problem is the slower loading times for graphics on the MAC36, with the HDMI display.

Good Practice

To enhance the performance of graphics on the MAC36 when using an HDMI output, it is crucial to optimize the graphic components and system settings. Here are specific, actionable steps to achieve better performance:

1. Use Tabbed Pane Instead of Canvas Pane: Switching from Canvas Pane to Tabbed Pane can significantly improve rendering times. Tabbed Panes are more efficient in managing resources when displaying graphics through HDMI.

2. Optimize Resolution Settings: Lowering the resolution can reduce the load on the MAC CPU, thereby speeding up the graphics rendering. Adjust the display settings to a lower resolution that maintains usability but decreases processing demands.

3. Reduce Widget Count: Decrease the number of active widgets on each page. Each widget adds to the processing load, so limiting their number can enhance performance.

4. Consult the Manual: Refer to chapter 6.11.1 of the MAC36 Installation and Start-up Guide for detailed advice on HMI preparation. This section provides additional insights into optimizing system settings and graphic configurations for better performance. Access the manual here: MAC36 user manual.
