C20 HDMI Video Issues

I’m having video sync issues with my new C20 and my 24’ HP monitors. I’ve replaced the HDMI cables, but it’s affecting both monitors and all the cables I’ve tried.

Resolution is only 1200x1920, so that shouldn’t be the issue. Has anyone had similar issues or have I just got a bad unit?


Hello Jamie,

Thanks for contacting AV Access,we are truly sorry for the trouble caused.
“Video sync” issues is the laptop output to two monitor no sync? Happened on both two laptops?

  1. Couly you try reset the monitor to have a test?
  2. Double check do both two monitors work in the same “Picture Mode” : Picture/ Picture Mode

Best Regards,
