Keby to bolo pre HDMI tak by to malo byt nejak sucasne s ovladacom grafiky, ten si instaloval ktory?
Daj sem link ak sa da na tie ovladace na www.hp.com (dufam ze to instalujes odtial)

BTW. nainstaloval si najprv ovladace chipsetu?
P.S. jaky to ma chipset? Stiahni ovladac chipsetu z webu vyrobcu chipsetu. Inac dobre by bolo nainstalit aj tie "Operating System - Enhancements and QFEs" obe.
