    Question HDMI input flickering between signal and blue after upgrade to 1911

    After we have upgraded various sparks (hardware: 1.7.15) to FW version 3.99.1911 we suffering with flickering images between the HDMI input (HD) signal and the default blue background the spark is giving when no signal is found. The NDI signal does not have any interruptions and the sound (jack) does not have any problems at all.

    Does somebody has similar experiences and does have a solution in place? A reboot of the spark does help for minutes, but the problem is occurring more and more after more time has expired.

    Thanks!

    I'd contact support to see if they have any suggestions on a solution. What is the resolution of the source going into the Spark? I've been using the 1911 firmware since it came out on my Spark HDMI (and SDI) unit without issue.

    The HDMI input is fixed on 1920x1080 25frames per sec

    I'm using NTSC frame rates here, but I would 1080p25 to work. Connect support using the link above.
