DJI has released new firmware for DJI Lightbridge


The new firmware includes the following updates:
  1. The video lag/stutter issue will be resolved in most situations. Delays caused by the use of third party hardware or software may not be resolved.
  2. The available options in Video Transmission Mode Settings will change to “Real Time Mode” and “Smooth Mode” (currently only “Resolution Setting” is available). In Real Time Mode there will be no apparent lag, but image quality may be affected. In Smooth Mode the image quality will be optimized, but the lag may increase.
  3. Support for customizing On Screen Display settings. You can adjust the location of the top, bottom, left and right side of the display, ensuring the OSD parameters will be visible.
  4. Support HDMI output 720p frame rate setting at 50HZ or 60HZ.
  5. Available transmission channels changed from 32 to 10. The frequency of these 10 channels ranges from 2395MHz to 2485MHz. Select appropriate channels within this range to comply with local laws and regulations.
