close / restore / minimize button / Monitor upgrade

Hello
I upgraded my monitor, from 27" 1920x1080 to 32" 2560x1440
The visual style i use it looks great, except the close / restore / minimize buttons. They are too small now.
So i tried to modify them from the Windows settings, but they look worse ( see attached image, please )
My OS is Windows 7 Ultimate x64

My question is : if i try to modify ( make them bigger ) with the software Windows Style Builder, do i have a chance to make those buttons to look better ?!
Thanks

Nobody can't advice me, guys ?

Windows Style Builder can make them larger but you will also need to edit the glyph images for the higher dpi that you are using.

Windows & Caption Buttons > Aero > DWM Window > Controls > Captions > Window > Close Button > Close Glyph > 120dpi
Windows & Caption Buttons > Aero > DWM Window > Controls > Captions > Window > Close Button > Close Glyph > 144dpi

and so on, either blank those images out or use what ever image you want to have there.

Could you, please, help me ?
I don't know what to export / import, from those glyph images.
