Connect multiple LCDs to one PC

Welcoem to the forums!

You need 2 graphics cards with 2 ports each. Hook 2 monitors to each graphics card. Make sure your power supply is adequate. The cards have to be both Nvidia or both ATI. You can mix AGP/PCIe and PCI cards, if you do not have multiple video card slots.
Afterwards you can extend your desktop across multiple monitors or clone it in Windows.
