I just bought a Lenovo ThinkCentre M75s-1 SFF with an AMD Radeon 520 graphics card. Lenovo assured me repeatedly the PC would be able to drive 3 independent monitors even if I used my existing monitors which I'd have to connect with DisplayPort to DVI Adapters. The card has 2 DisplayPort Ports so those monitors work OK.
Problem is, the VGA port (not on the AMD card) seems to have been disabled by the AMD Radeon 520 adapter. That port was supposed to drive the 3rd monitor, but even with the DP ports disconnected, Windows 10 doesn't see it.
So, can anyone tell me if it's possible to use the 520 to drive 3 independent monitors? Can I get some sort of splitter or hub? Can teh 520 even do that? Do I need to tweak the BIOS? Have I been ripped off?
Thanks in advance.
