DisplayPort version on Optiplex 790
I need to connect an Optiplex 790 to a monitor that only takes HDMI input. The cheapest DPort-HDMI cable I can find says it's a "Passive Converter Cable", and that it requires a Dual-mode DisplayPort (DP++) source. I can't find anywhere in the Optiplex 790 specs whether its DisplayPort output is DP++, so I thought I'd ask here. Will this cable work?

What model video card or integrated video? That determines what type port you have. Most monitors don't have speakers so the passive cable should work. See this cable description for more info about passive--
This DisplayPort adapter cable operates passively and is designed for use with dual mode graphics cards often designated with “D++”. HDMI audio is supported by this adapter cable when connected to a device that possesses dual mode and HDMI audio capability. Although the vast majority of source devices support HDMI with audio, some are incapable when using a passive adapter. If you are uncertain if your source device supports HDMI audio with passive adapters, please consult with your computer or graphics card manufacturer to verify.

I'm talking about the output port that ships with the Optiplex 790. I assume that's integrated video, but I haven't cracked it open to check.
