vb.net - AutoScaling WinForm Display (Small, Medium) -
first , foremost, please forgive me screenshots in french due windows installation @ work. still easy understand though. i'll include screenshots make more visually appealing.
here's background information:
- windows 7 64bit
- visual studio 2010
- default display 100%
- autoscalemode: dpi
- autosize: true

my application windows form developped in default (small - 100%) display. so: 
as can see, "petite" or small display default selection.
small display - 100% (default)
here how application looks setting. this correct display 
medium display - 125%
the red rectangles point out unwanted empty space. 
i have tried:
- anchoring / docking controls such split containers, table layout panels, list views on form_load and via ui. didn't work.
- adding split container form, , controls respectively separated it
- adding table layout panels, textboxes , buttons located in respective cells
i thought having scaling problem because of anchoring , docking. although didn't seem problem ... seems having trouble tab control , listviews ...
some users (most) have settings default (100%) there few have @ medium setting, causing scaling issue. there way fix this?
i cant see screenshots or links reason cannot visualize problem. if scaling problem, try setting autoscalemode none.
i had because winform app image intensive , not render correctly on medium settings because built using default small settnigs display. changing scale mode none worked me.
