Horrible Display with New PC and Monitor

[C_Dub]

Hello. I'm new to this site so if I am posting in the wrong place then i'm sorry and I will repost in the correct subforum. Three days ago i received the Gamer Xtreme 1353 from CyberPower and the ASUS VG Series VG278H Monitor. The GPU is a Nvidia Geforce GTX 650. I have the monitor and gpu connected via an hdmi cable. The screen resolution is set to 1920x1080 (native) yet the screen is very blurry and text is quite distorted. I have the latest driver for the gpu, however the VG278H only has drivers for windows xp/7. I did attempt to download the windows 7 driver (not sure if this is a good idea anyway) however it said no system hardware could be detected. Any help would be very much appreciated

I have the latest driver for the graphics card, not exactly sure what else i can do.

Are you able to test either the monitor on another PC, or the PC on another monitor,. to determine which is causing the problem?  Alternatively does the monitor support a different input, like DVI or Displayport, which you could try to see if it's just the HDMI causing problems?
