Thanks. The adapters do not work well (I tried them) and do not provide highest resolution that the CD can display.
The cards with MD-ports mostly are high end and require high power (> 300).
Here is one I was considering....http://www.amazon.com/ATI-FirePro-Mini-DisplayPort-PCI-Express-100-505610/dp/B003N75ZCA/ref=wl_it_dp_o?ie=UTF8&coliid=I2QJLG0CTEF8FT&colid=3BTTIS5JF2F77
I wonder if it will replace my current card (that is, will it fit the slot, use the right power, and be compatible)?
