VLC on 2nd screen only showing garbled lines + significant lag

Postby macvlcuser » 15 Sep 2019 16:09

Have a 2012 Macbook Pro Retina trying to play a mp4 on my TV connected via HDMI (see image below)

Video runs smoothly on my main screen, but when I drag VLC over to the TV (or change setting to auto full-screen on the TV), it only shows garbled lines + vlc player is extremely slow on 2nd screen.

Audio works perfectly on 2nd screen but no video (full screen or un-full screen).

Not sure how to make it work - any help is appreciated!

Troubleshoot methods:
  • Restart Mac
  • Update software/drivers
  • Reset VLC preferences
  • Reinstall latest VLC version
  • Tested video playback using youtube in 1080P on Chrome on 2nd screen + playing same movie in quicktime full screen (no issues)
  • Changed video output module to: MAC OS X Open GL, Core Animation Open GL Layer (Mac OS X)
  • Forced Open GL/GLES hardware converter to the Apple OpenGL CVPX converter
  • Increased file caching to 600, 1000, 3000, 6000 (all in ms)
  • Turned on/off Video Auto Scaling
  • Turned on/off Fix HDTV height
  • Turned on/off Deinterlacing

Are you running on macOS 10.14.6?

Additionally do you have a dedicated NVIDIA GPU? (You can check in "About my Mac" > "System information" > "Graphics/Displays")
