firepro w5100 don't find two monitors

Hi everybody

I dont speak English well but I hope you will understand me

I have computer HP EliteDesk 800 G1 TWR and videocard FirePro W5100 with four DisplayPorts.

OS Windows 7 64bit. I want to use 2 monitors - first is AOC 2365 (with dp-dvi adapter) and TV LG (with dp-hdmi adapter). If I connect two displays simultaneous I see desktop only on monitor AOC. If I connect or monitor or TV - I see desktop on monitor or TV. Screen property dont find two displays, so I cant change display mode. Driver version for card is 17Q3. How can I get two displays?
