External monitor is blurry

Monitor is a bit blurry

I just built a new gaming rig and am using an XFX 6950 and an ASUS 23.6" monitor. On some pages, I notice some fonts are a bit blurry and strain my eyes. Any idea how I can fix this? I am using windows 7, so please make the steps work for that. Thanks.
