ok found it, one of my osd menu choices is auto, it is one of 5 menu choices,
Empowering: Press the Empowering Key to open the Acer eColor
Management and access the scenario modes.
Auto: Press the Auto button to activate the Auto Adjustment
function and the monitor will automatically optimize the
display position, focus, and clock of your display.
Menu: Press the Menu button to activate the OSD menu.
Volume: Press the Volume button to adjust volume. (Optional, only
Audio-Input Model)
Input: Press the Input button to select from different video
sources that may be connected to your monitor. (Optional,
only Dual-Input Model or HDMI-Input Model)
when press and holding the auto button, it flashed by "configuring" and voila it results in a full screen, ie. on the laptop system it is the screen on the laptop screen
there is one thing that is still very weird but I can live with at this point, I can still slide a window past the edge of the screen bevel if I keep moving it beyond the edge it eventually flashes back onto the screen with its original width and full vertical size from top to bottom bevel and all the other windows that were on screen are made smaller all the same size. when I click on any of them they also change size to a full vertical size and some predetermined width. from there I can resize them to what I want. as I create new windows and move them around, I will probably notice if they go beyond the bezel and I will put them back.
I will have to check the behavior of other monitors. I seem to remember that when the screen showing is full size within the bevels, that any windows on the screen are contained to that size, ie, if I move to any of the 4 edges of the bevel, I will be stopped there and not be able to literally move the window past the bevel, which IMHO is the best solution. If you can check this on your monitor and post back I would appreciate getting the feedback.
