Instructions for those of you who have trouble with BS resolutions (860x720). Example: the main window is resized, but the contents are still large. The issue with the original reg file was that it was missing the height/width keys. Here's how to create your own file if you are wary of downloading it:
1. Open notepad.
2. Paste the following code in the window:
Code:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\BlueStacks\Guests\Android\FrameBuffer\0]
"WindowWidth"=dword:0000035C
"WindowHeight"=dword:000002D0
"GuestWidth"=dword:0000035C
"GuestHeight"=dword:000002D0
"Depth"=dword:00000010
"FullScreen"=dword:00000000
"WindowState"=dword:00000001
"HideBootProgress"=dword:00000001
"Width"=dword:0000035C
"Height"=dword:000002D0
3. Save file on the Desktop as "860x720.reg"
4. Double-click on the file and click OK Twice.
5. Restart BlueStacks by right-clicking on the icon in your taskbar and clicking Restart.
