Hi everyone,

I want to connect my MacbookPro (Mid 2009) to two Dell monitors and close the lid of MacbookPro and use one monitor as main display and the other one as extend display. I've been looking around on the internet but couldn't find the answer. If you guys can help me with this, I appreciate it a lot. Thank you very much.

Update: I found this but I'm not sure if it works and preserves the image quality.

Might want to list how old your Macbook is because that will help people understand what type of connection to use.
 
Both mid 2009 13" and 15" have mini-display port. It depends now on what are the available connectors in your dell display. You could get a mini-display cable adapter to VGA, DVI, mini-display, display, HDMI, or Thunderbolt...

My question is how to connect to TWO monitors?

Oups, I didn't have my glass... :D

I am not sure but if you have only one mini-display output port, then your gpu supports only one external display. I don't think you could connect to 2 monitors, and even if you split the signal into two cables, then the 2 displays would be mirrored...

My 2cents
 
Use an Apple TV and air mirror the display to the second monitor?

Or wait for Mavericks which gives you the Apple TV as a second external monitor separate from the inbuilt display.
 
I think the cable you posted would display the same image on both displays.

You probably need one of Matrox's adapters:

The other option would be to plug in one monitor via the mini-displayport and get a USB video adapter for the second monitor. The performance on USB adapters is usually not very good (fine for spreadsheets etc. but not for high res video) and you have to make sure you find one that has Mac drivers.

I use to run tow displays from my 2009 MacBook Pro, one connected via the mini-display port and the other via a EVGA USB graphic adapter, older version of this http://www.evga.com/Products/Product.aspx?pn=100-U3-UV39-KR

In the end the performance of the UGA was not good enough for me.
