How do I increase the resolution of BlueStacks? Presently, my BlueStacks appears slightly blurry. By blurry, I mean 'not sharp'. 
Compare BlueStacks with my desktop:

The difference is subtle, but I don't like it. I think it's got something to do with the resolution. How do I increase it so that the items in BlueStacks appear sharp?
To change the Resolution of BlueStack:


Open ‘regedit': Start->Run->regedit
Navigate to: 'HKEY_LOCAL_MACHINE/SOFTWARE/BlueStacks/Guests/Android/FrameBuffer/0/’
Double click the value ‘GuestHeight’
Change Base to Decimal
Input your desired Height resolution 
Double click the value ‘GuestWidth’
Change Base to Decimal
Input your desired Height resolution 
Restart your PC, Open BlueStack [It will open up with New Resolution.]
