I have a HP laptop I hooked 2 external monitors up to the lap top using a HDMI to DVI double splitter. I can ot figure out how to split the monitors setting is only detecting 2 monitors one being the laptop screen and one of the additional monitors I connected. so its only detecting 1 additional monitor and only working in clone. Do I need to buy a different splitter or is there a setting to fix this I was to be able to use both external monitors as separate screen I do not even want to sue the lap top screen
