60HTz 120Htz eye

[pedroluizcs]

Hi.
I already did a search at Tom's Hardware forum and google but I never found a place that explain it.

I would like to know what hurts more the eye, a 60Htz LCD or 120Htz LCD monitor.
Or is it the same?

I am going to buy a notebook and will use it a lot so if 120Htz hurts more our eyes I will buy a 60Htz.

Thanks in advance,
Pedro Luiz

for the majority of people brightness and ambient light are more common problems than refresh rate on lcd monitors. any flicker percieved by the remaining minority is due to the backlight and not the screen itself.

if you are one of the minority that is succeptable to the flicker of the CCFL/LED backlight from pulse width modulation (PWM) then just about the only thing you can do is get a model that disables PWM at 100% brightness (normall not LED backlit ones) and put a filter screen on it to reduce the brightness, though this does give it a more faded look.

i've heard that someone replaced the backlighting with incandescent to solve their problem but with a laptop that is not feasible. even on a normal monitor it wouldnt be for the average joe.

if you are one of the majority that is unaffected by PWM then the best thing to do in order to avoid eye strain is to set the brightness at a comfortable level, use ambient lighting, use a resolution that doesnt require straining and taking 20-30 second breaks every 20min or so. this doesnt involve getting up, instead just focus on objects 10+ feet away to let your eyes focus on something else.

to answer your question simply: i've never heard of a study that compared 60/120hz eye strain. i've noted problems i've seen & solutions.

Thanks ssddx. Helped a lot. =)

I am going to set this the best answer but if anyone who enter this forum know more things about it pls post.

Thank you.


A long time ago I read something on internet that said if you have a 60Htz monitor and choose other Htz (the wrong value) at your configuration It could hurt a lot our eyes. But I think this information is wrong.
