Laptop refresh rate at 75 Hz native res - damage?

At 60 Hz my laptop bugs the crap out of my eyes, at 75 Hz... just fine. I want to run at native res 75 Hz, but been reading that this will/might damage my laptop's display. Is it really a danger?

BTW: I know I've been posting like a madman today, I appreciate your guys' help, verily.

 

No, you'll be fine.

Although, that doesn't make a lot of sense since LCD's do not function the same as CRT's and the refresh rate shouldn't make any difference to your eyes.

 

Definitely there's a difference. At 60 Hz it seems like it hurts to watch, but just barely. Then I switch it over and it really seems like whatever it was is gone.

 

so, would it be fine to set the laptop refresh rate to 200hz? why aren't higher refresh rates made available if they dont hurt the laptop?

 

High refresh rates don't hurt anything, there are just limitations to how quickly the screen can refresh the image. You can't get a 200Hz refresh rate because it can't physically do it and you wouldn't be able to tell the difference anyway.

 

Then setting the refresh rate frequency to 75Hz as a standard would be appropriate.

I personally don't experience issues at 60Hz on my laptop (then again, it's possible I grew accustomed to it), but it would be nice to have a slightly higher refresh rate available as a standard since they know 60Hz is the bare minimum for some people's eyes to tolerate.

 

In what environment are you experiencing this? If the lights/power are pulsing in sync with your screen, then yes it will hurt to look at the screen.

In a naturally lit environment (or a completely dark room), do you still notice this from your screen?

If you do (and you also notice this with other screens/notebooks too), then it is that you are super sensitive to this phenomenom. If you don't, then it is an interaction with the pulsing of the lights in the room/environment you are in.

If you only notice it with your notebook/screen, then it is defective and I would look at replacing it instead of running it at a higher than nominal refresh rate.

Good luck.

 

But the thing that troubles me with what the OP is saying is that there should be nothing noticeable on an LCD screen when changing the refresh rate. People being sensitive to lower refresh rates was a real issue with CRT's. When each pixel is hit by the electron beam, it gets lit up. This doesn't last for long and it stops glowing quickly. At lower refresh rates, the delay between hits of the electron beam would allow one to see a very fast flickering of the screen. At higher refresh rates this flickering would be unnoticeable however.

With LCD's it is a totally different story, as each pixel is continuously lit and maintains its color and shade until told to change. In this case the refresh rate is just how often this change command can be given. Higher refresh rates are preferable for 3d shooters, but not for much else. Movies are always far below 60fps, and they appear smooth for the most part, so there is really no advantage to higher refresh rates outside of a few uses.

 

Put it that way - you can run your laptop on any refresh rate that is supported - and only the supported ones will show up.

On another note - my laptop runs at 60Hz normally - and in energy saver mode at 40Hz - looks the same to me, 40Hz needs less energy

 

the question is, why does windows limit the refresh rate when it doesnt have any adverse effects?

btw, when i change the refresh rate on my desktop from 75hz to 120hz, (although the monitor only supports up to 75), windows becomes MUCH faster, everything from opening windows, closing windows, to menus appearing

 

Actually if the screen supports it 75 Hz is much better. The reason is the eye recognizes about 24 Hz. in real life as things move they will motion blur within each optical refresh. Computers display fixed pictures without motion blur but instead a pixel shift. At 60 Hz the eye gets to see an average of 2.5 pixel shifts per refresh. With 75 Hz that goes up to about 3 shifts per refresh and the higher the screen refresh the more pixel shifts per optical refresh.

The more pixel shifts it can get per optical refresh the more it then mimics natural motion blur with the appearance of pixel overlay. This makes motion appear more fluid and is less stressful to the eye itself.

There are other important factors too, such as the off time for the pixel before it refreshes its color as a higher refesh usually has to go in hand with a faster responce time etc..........

 

i feel like .. if windows is synced to the screen at 60hz, then "how" the elements within Windows load, like how fast menus appear, are also synced to 60hz, and if you set windows to 120hz despite the screen not supporting it, then frames are skipped, and things appear quicker than if it were set to 60hz (this is even without Window's animations)

i think by having windows synced with the screen at 60hz is sort of like having vertical sync on in games, everything is more sluggish, and when you turn it off, everything is snappier

back when i used to play around with refresh rate on my desktop (years back) i know for certain that everything was snappier when i increased the refresh rate to something higher than the recommended refresh rate of the monitor, the higher i set it, the snappier, menus and windows would literally appear significantly faster. but i kept my "refresh rate overclocking" to a minimum because i was afraid it would damage the monitor

 

i really can't tell the difference in between 60 and 75Hz but i certainly prefer 60Hz.. 75Hz on CRT gives me headaches... anyways if ur display's max supported refresh rate is 60Hz, how can u go above it? Its really illogical...
