I recently purchased a Mini DisplayPort | Thunderbolt to HDMI with audio support for my MBP to hook up to my external monitor so I can dual screen. Here is the cord: http://www.monoprice.com/products/p...=10428&cs_id=1042802&p_id=5311&seq=1&format=2 Now my question is... my external is capable of 1680x1050 however in the system preferences the best I can do on it is 1024x768. Does anyone know a fix on how I can get better resolution? Here is a link to the monitor if it helps at all. http://www.newegg.com/Product/Product.aspx?Item=N82E16889107035 Thanks!
