You can use the WIN32OLE library (or similar) to call the
GetSystemMetrics() function:

Thanks Wilson!

require 'dl/import'
require 'dl/struct'

SM_CXSCREEN = 0
SM_CYSCREEN = 1

user32 = DL.dlopen("user32")

get_system_metrics = user32['GetSystemMetrics', 'ILI']
x, tmp = get_system_metrics.call(SM_CXSCREEN,0)
y, tmp = get_system_metrics.call(SM_CYSCREEN,0)

puts "#{x} x #{y}"
