hp2710

I was given the HP 2710m monitor with built in speakers.

 I connected it to a Dell Studio 540S, Intel Core quad, 6 GB ram, 64 Bit Windows 7 computer. 

With the VGA cord connected, I have a great picture but no sound. 

With the HDMI cord connected I have sound but the font is terribly blurry everywhere, regardless of what program, browser or software i'm running. 

I just bought a DVI to HDMI cable to try, it gave me a good picture(didn't fit the monitor) and no sound.

I also tried plugging in a cable from the audio port on the monitor to the audio port on the computer.

Within the sound settings, unless the HDMI, cord is plugged in the monitor is not an option to use. 

Any idea how to get a good picture with good sound? 

Thanks in advance.
