You can use 2 monitors if you buy yourself a secondary GPU (Graphic Processing Unit -- or -- Video Adapter) depending on the model of GPU you purchase. Some GPUs come with 1 x VGA and 1 x DVI port and some come with 2 x DVI port (Use VGA to DVI convertor in case your LCD does not have a DVI connector). As for secondary adapter disabling built-in X3500, you have the option in BIOS to switch to either of the Video Adapters i.e. On-Board or External

I have my DG35EC Hooked up like it has 2 monitors (Dell Video and HDTV).
Keep in mind that there are improved video drivers.
1-DVI - HDMI (converter) => HDMI Cable (Audio Separate).
I usually watch Koren movies with English Subs, Youtube, etc.
The integrated video will not do full HD, just around 720p.
I think if you put a video card in the slot it disables the built-in Video.
