On the Surface Pro, Bonsai looks very small and no matter how you adjust the resolution. But not to worry, there is a FIX!
________________________________________________________________________________________________
FIX: Download the javaw.manifest attached to this article and drop it in:
C:\Program Files (x86)\bonsaipos-3.XX.X\jre1.8.0_102\bin
Once that is finished, open up regedit and navigate to:
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > SideBySide
Right-click, select NEW > DWORD (32 bit) Value. Give it a name: PreferExternalManifest, and then press ENTER.
Right-click PreferExternalManifest, and then click Modify. Enter Value Data 1. Click OK. Exit Registry Editor.
Restart the tablet.
Once its back up, right click on the desktop, select Display Settings, change the size of text/apps to 150%.
Start Bonsai and the resolution will be fixed.
