Hi there, I just bought an Asus 2560x1440 monitor and I am trying to connect my MacBook Air 2009 to it. The fonts on the monitor are not super crisp. I have the Hdmi cable plugged into the back of the monitor. The other end of the HDMI cable is plugged into the Hdmi to Mini Display Port adapter. That adapter is plugged into my computer. What am I doing wrong in order to get grainy looking fonts and not crisp hi-res looking fonts?
