Your laptop would have to be Miracast or WiDi certified. If it's not you can't do much about it as software can't bridge the lack of hardware.
For example no matter what driver or software you install, there is no way in Hell you can print to paper without the printer itself.
-EDIT-
According to HP, 4440s supports WiDi (Intel computers will support WiDi, not miracast). Go to HP support page for your computer and in multimedia driver section download and install "Intel Wireless Display Software". After you install it it should scan arround and offer you any wireless capable display to project to.
Some systems will simply detect the display as it was plugged in via cable - Windows 8 and Windows 10 will see it available if you simply press Windows Key + P, not sure about 7, don't have any left.
