Always, when I want to resize the window to one of the bigger resolutions (bigger than my screen resolution), it resizes only to the screen resolution.
For example: I want to see my webpage project working on the 1680x1050 resolution, but if I want to resize it, the screen resizes only to the 1378x780 (my screen resolution is 1366x768). All resolutions bigger than 1378x780 always resizes only to this resolution and no more.
I have Google Chrome 29.0.1547.62 (latest stable) with default settings on Windows 7 (completely updated). It is on the notebook (screen 15,6'' and max 1366x768). I remember, that my PC (about two years ago) resized the window perfectly, but on my new laptop it has this bug. (Sorry for bad english)
