When connecting a laptop with an Intel Iris Xe GPU to a ViewBoard or other display via HDMI, a "no-signal" message appears on the display.  The connected pc detects the display but is unable to display an image. 


This behavior can be caused by the incorrect Color Format setting of the Intel Iris Xe Graphics.
