I want to play a video file on two different screens connected on an HDMI splitter which is connected itself to the video board.
The problem is that these two screens take a different amout of time to process the signal before displaying it.
I can measure a delay between 40 and 100ms to display a frame from one monitor to the other.
Usually this problem come with audio and the solution is to delay the audio but that is not the point here since we're only dealing with video signal.
I think the only solution it to delay the signal going to the fastest screen but I can not find any capable device.
