Customer reported platform

linux

Steps to reproduce

1) Open Nuke Studio, import some footage and add it to the timeline

2) Open the Viewer Monitor Out Panel, and set the device to Monitor Out hardware, like a AJA or Blackmagic card, setting the display mode and pixel format to something custom.

3) Switch to the Node Graph and create a CheckerBoard node and view it, the Monitor Out display does not update with the new image. If you do enable monitor out on the viewer node, then is does not retain the settings from the timeline.
