On my E773c monitor my screen is blurry and you can't read it at times. It will be fine then turn blurry then be fine again. I did the monitor self test, that didn't work. I have my brightness and contrast controls low, it's better put still is blurry. I went to dell solution center and they said to perform a monitor reset and or lower my video resolution or increase font size. But they don't tell me how to do this. I don't know much about computers so could someone please help me. Thank you.
