Functions implemented in this application 1) Query output mode list 2) Update properties of output (transform, scale, mode setting) 3) Position of output (leftof and rightof are supported.) 4) Custom a mode for output. 5) Delete mode of output. 6) Combination of above 2-5 in one shot.
Note: Does not support operations on multiple outputs in one time.
