ATI HD5670 and 3 monitors

[macmarac]

I have ATI HD 5670 775M 1GB DDR3 DP HDMI DVI PCI-E graphic card and I can not rum 3 monitors at all...
I have 1 monitor on DVI port, 1 TV on HDMI port and 2nd TV on Display port via DP to HDMI adapter, and AMD Catalyst do not allow to connect 3 monitors...
I've been reading a lot about it and it should worked but it will not.
Does anyone know anything about it?
Thanx
Marac

I recommend these steps....
1) run amd autodetect and driver download
Obtaining Graphics Drivers Using the AMD Driver Auto-Detect Tool | AMD

2) make sure your issue is related to running three monitors at once, that is, make sure you can run each monitor one at a time. So unplug two monitors and boot just using dvi only, then reboot with one monitor using hdmi only, then reboot using just the displayport-to-hdmi using the adapter.

3) Assuming that works, then reboot with all three monitos plugged in and post a screenshot of start > run > desk.cpl > detect. If all three of your graphics card ports are workng, windows should detect three monitors
