I use mozilla firefox and changed the font size...am now quite happy with the result. Have not been able to get the digital connection to work. Dell is sending me another monitor - we'll see. Dell's tech service is absolutely horrible. For example, i spent 3 hours - yes 3 hours yesterday with them as i had not gotten the replacement monitor. They had no record of such and it took 3 hours with too many people to count. An awful experience. I found reading posts here and doing a google search helpful. Good luck.

To find out what card you have, go to the device manager and check what it says under display adapter. It will give you the name of the adapter.
