Hello, I am trying to connect my Macbook Pro (bought Fall 2009) to a external monitor - an Asus VW222. I use a VGA converter which I bought together with the mac, I plug a VGA cable in the converter and then I plug it into the display port of the mac. I do get an image on the Asus monitor, but it is not very useful. It is flickering between a yellowish color everywhere and normal colors. Moreover I cannot change the resolution. If I set the resolution to 1680*1050 (the Asus' native res) then the image still looks scaled/grainy and it doesn't fit on the monitor. The top menu for example is outside of the screen and the whole image is slightly moved to the right so I have a black bar to the left. If I set the resolution to the mac screens native res, 1440*900, the image fits on the Asus but is of course scaled. I tried go to system preferences and calibrate, but it did not help. Can someone help me identify the cause of this?
