Cathode ray tubes are a thing of the past. Most people have been burning there eyes out on Cathode ray tubes for the last half a century. Just like margarine, Cathode ray tubes can cause retina detachment. So we are told too buy the new LCD monitor for use on the computer to avoid Cathode ray tubes. The AL2416WD wide screen is a cheap new-gen screen that isnt really cheap. Setting this non Cathode ray tube thing up was about as easy as smashing ones face against the mirror. Graphics card would not accept the display settings when installing the bundled program.
