Hi, I recently got a Dell 24" 2408WFP. I noticed that the image on the display is significantly better when my MBP's display is closed and off. Has anyone else noticed this? It seems as if the display it self gets a bit more blurry. Also, I double checked to make sure the resolution was 1920x1200 @ 60 Hz, Millions of colors with and without the MBP being open.
