Hello! I have a notebook with Intel Core i5-3230M. I read in specs and this proccessor has GPU which could work with 3 monitors. I want to use laptop screen and two external monitors (connected to HDMI and DVI) but I can't do that.

Intel graphics control panel allows to work only with two displays simultaneously. https://drive.google.com/drive/folders/1HFUOx40bs4dFG58Hm3wO-2RKwdrzBWQe?usp=sharing

Whether the three monitors can all be exposed simultaneously is dependent upon how the monitor ports were implemented in the laptop. It actually has nothing to do with and is not a bug in the Control Panel applet, which simply exposes whatever monitors are enumerated (i.e. no enumeration = no support). What is the exact model (full part number string please) of this laptop?
