Troubleshooting

Video playback does not start on the Video-Wall, while I can see it working on the “Master” Player
  • You need to have a video with an audio track working on the “Master” Player to start playback for the other Players. This is a restriction that we are working on and will be removed in a future release.
Video playback is not smooth. There are stuttering and glitches.
  • The whole system needs to work in the same FPS and Hz. It would help if you did the following:
  • Check the FPS of the video content you are showing. It should either be 30 FPS (or 60 FPS) or 25 FPS (or 50 FPS).
  • If you have a mixed set of content (both 30/60 and 25/50), select one of the 2 to start a test and see which setting looks better.
  • If you have 25/50 FPS content, then you need to set the output resolution of all Players (including the “Master” Player) to 25Hz (or 50Hz).
  • If you have 30/60 FPS content, then you need to set the output resolution of all Players (including the “Master” Player) to 30Hz (or 60Hz).
  • Use these instructions to change the resolution of the Players. In the standard case, you should use 1080p or 720p resolutions (depending on your screens).
  • Evaluate and, if the result is not satisfactory, start over with a different setting.
The video seems of low quality.
  • Check the original video source on your PC and make sure that it is true of better quality.
  • Check that the HDMI source (in most cases, the Player) runs in Full-HD resolution.
  • Check out the next guide on upgrading the firmware on the LKV373A to have a Full-HD resolution (1080p) instead of HD-Ready (720p).
The screens on the Video Wall are not 100% synced.
  • Check that the screens do not have any picture processing activated. A lot of brands have advanced features that process the image to appear smooth and have great motion. Try deactivating as many similar features are possible, reduce image “clarity,” “smooth motion,” and things like that. Make sure you do this on all TVs.
  • If the TV has a “game” mode (used for console gaming), try using that – it should eliminate lags. Make sure you do this on all TVs.
  • Power off the LKV373A for 2 minutes and then power it up again. Players should restart playback and should be synced. If the issue is corrected at first and then happens again, try using a different network switch. The switch might be inducing delays.
