Does anyone use this monitor alongside their Macbook or Macbook Pro? http://accessories.us.dell.com/sna/...etail.aspx?c=us&l=en&s=dhs&cs=19&sku=320-5629 I realize it is a low end display with very few options, but I am having a hard time getting it calibrated. I have tried many times and I can't get a nice, sharp picture. If you have this monitor, can you let me know what calibration settings you use to make it look decent? Thanks.
