Can a flatscreen LCD monitor with a low refresh rate cause blindness?

Q. My brother has been convinced (by a computer salesperson, surprise surprise) that his flatscreen LCD computer monitor is going to cause him to go blind because its a couple of years old and has a slower refresh rate. My husband and I think thats bunk and that the salesperson is trying to pull one over on him. Anyone know for sure?

A. I would report that salesperson ... he's trying to use scare tactics to make a sale ... the one thing that was noticeable about early LCD monitors with slow refresh rates was that they tended to "flicker" a little under florescent lighting which in some cases caused headaches ... but if this isn't a problem with your brothers ... use the old adage ... if it aint broke don't fix it


What is the best frame refresh rate for a 19" LCD wide screen monitor?
Q. I just purchased a new AOC 19" LCD widescreen monitor for my pc, and every view seconds I see diagonal lines over the screen. Should I change the refresh rate of the screen or is it something else?

A. you should check in the manual, or on the box, you may need to install the drivers in some cases..

the manual should have the best settings "resolution, refresh rate etc" for your monitor.
