Getting headache looking at lcd screen z70v?

Ok here is a weird issue i have heard of this on crts with a low refresh rate but never an LCD. Ok i just got my z70v yesterday i love this damn computer so much and ive never had an issue like this with any monitor i work in IT so ive used every kind imaginable, i dont think its my imagination but when i look at my z70v i start to feel umcomfortable like a little but sick and small headache. i thought it might be the small font but makes no difference but as soon as i look away from the screen i like feel better. am i going nuts anyone head of this and if so is there a solution? i really dont want to send this pc back i love it.

 

Yes its called uncalibrated predetermined Hi-res small screen sickness. Options? Get a new laptop with a lower resolution, try to adjust or lower the resolution. Also try to restrain you sel from over usage. _

 

What are you coming from? - Screen type, size, res

Have you played around with the refresh rate at all?

 

my main pc has a 20.1in widescreen with 1680 by 1050 and i had a 14 in laptop SXGA with 1400x1050 i think. and a 1280 by 800 compaq. And as for the gear2play guy i got this laptop from u i didnt like the z63a screen so u guys were nice enough to switch for z70v. i would hate to have to send it back to you guys its a hassle for u and me. And as for chaging the refresh rate the only option it gives me is 60hz any way to bump it up?

 

and as for over usage i havent i mean i feel it after like 5 minutes on it. i mean im one of those people that can pretty much tell what refresh rate a monitor has by looking at it. i have lowered the res. but no luck. i have read sometimes the type of back light used can cause it but again never had this issue.

 

What's your backlight level? If the text may be bothering you, I suggest using the program "eyerelief". Google it and you'll be able to find a place to download it. It lets you keep the resolution you bought, while increasing the size of the text without distortion.

 

Its not the font though its the screen itself. and i do use eye relief. and have been using all different back light levels. is there anyway to bump up the refresh on the lcd.

 

No, 60hz is normal. What was your last laptop?

 

my last laptop was a compaq R3000z glare type 1280 by 800 and a dell D600 1400x1050 i think it. it was sxga it was given to me i wouldnt buy a dell. my desktop refresh is 72hz but thats a desktop lcd so no comparison there. but the other laptops were set to 60hz as well.

 

It might be worth checking out your eyesight.You may be having longsightedness(reading lenses)

Just my 2 cents --

 

my vision is fine i dont have any probs using sxga infact i prefer them. its very hard to explain. anyhow im gonna use it for a week see if i can get used to it id hate to part with it.

 

Hi SRD,

I have a Z70V as well. My last laptop was an Inspiron 8100 w/ 15" SXGA+ screen like your Dell... my only issue is I found max brightness to be a bit of an eye torcher so I keep it down somewhat low, but it seems you've already tried that.

It might just be psychosomatic - something about the screen at first impression sent your head into a loop... you thought it was off somehow, and now your brain is continuing to hold onto this impression, even if there's no real sensory basis for it.

I had this problem not too long ago with my first set of IEMs (in ear monitors) for listening to music at work. My ears were unused to the amount of clarity and the treble produced seemed excessive. I was worried about damaging my ears so I kept them really low. Over the next several days it seem tinitus symptoms were beginning to wear on me, a very large hum developed and I couldn't sleep by the end of the week. So I put them away. A couple weeks later I read this is fairly common experience people go through and there is no basis for what I was experiencing, I tried them again and not a problem since, even using at pretty decent volume all day long.

 

BTW, the refresh rate on a LCD is not the same as on a CRT. An LCD does not consistently scan a new image, it's just a restriction on how fast it can update under animation. IOW, if you're looking at a static image it doesn't matter if the refresh is 1 hz or a million hz, it's not doing anything.

OTOH, with a CRT the image is drawn, then it decays, then drawn, decays... so refresh rate is important no matter what the situation. If the refresh rate is low you get a flicker effect due to seeing it do this.

 

I Know the difference in crt and lcd tech and the whole refresh rate difference. i just want to try anything i can to be able to keep this laptop since i like everyting about it. I really dont think its in my head i, it might just need an adjustment period because even though i use svga on my desktop it is a much larger screen so it might make a differnce but we will just have to see. the monitor is very sharp and clear. oh well.

 

Maybe try using it for a bit once in a while.

I used to get massive headaches and get 'woozy' when I change my CRT resolution, from a 15" to a 17". But I got used to it after a while.

I don't know how this can help. but keep it at 'em

 

Umm... you wrote "And as for chaging the refresh rate the only option it gives me is 60hz any way to bump it up?"

If you did, you wouldn't have asked this. In case what I said wasn't clear, basically the refresh rate is not responsible for your issue.

As to an adjustment period due to the actual resolution itself I disagree - you came from a 14" SXGA+ laptop, right? That has a higher pixel density.

 

i just wanted to try changing the refresh for the placibo effect of it. i know i came from a 14in sxga yes the pixel density was high er but i havent used that one in a few months. ive been using a 1280 by 800 laptop lately. i was just saying i had a 14in sxga and i never had an issue with it. just maybe not using it for a few months was the prob.

 

LCD's, unlike CRT's and Plasma screens, do NOT flicker. So there is no need to increase your refresh rate more than 60hz, unless you have a very responsive LCD and it refreshes faster than 60hz (like some of the very latest LCD's with 6ms refresh). With CRT's you want to set your refresh rate to AT LEAST 85Hz or you'll get bloodshot eyes and headaches. If you're getting headaches from staring at your LCD, it's probably because you're straining your eyes to read it (and your forehead). If you click on ADVANCED where you select your resolution (which should be as high as your LCD supports to have a sharp image) you can increase you DPI to make everything bigger. Try setting it to 120dpi and see if this alleviates the problem.

 

That's my guess. The mind truly is amazing at what it will adapt to, or conversely adapt against. The retina actually sees things upside down which are flipped at the brain itself. There have been studies where, when the subject was given a pair of glasses which inverted the image, within a week of major discombobulation the person was able to see upright again - essentially telling the brain to stop flipping the image. Then walking around without the glasses everything is upside down!

One other thing I'm not sure has been mentioned is to play around with the color. There's color calibration software out there that may help. What I perceive as a super bright screen could very well be in part to a bit too much vibrance in the color palette.

 

I heard about that study as well... it kind of makes me want to put on those glasses. Man that would be cool.

 

I would love to wear those glasses and walk into a bar

 

Ive been using the z70v more and it doesnt give me a headache anymore. but it is still uncomfortable looking at it i put my14in dell D600 on the side with both pcs on and the dells fonts are smaller and so is the screen but i can read and view it very comfortably from farther away. its like i have to strain to read the z70v screen even though the font is bigger. the dell i have no issue at all with. even when viewing videos on the z70v it bothers my eyes like i have to try extra hard to make out the screen it reminds me of a crt on low refresh rate but i know that should now apply to a lcd. this is driving me nuts. and the dell monitor is dimmer and less sharp and i view it alot easier. didnt some people complain a while ago about using the z71v?

 

At this point i would say there is absolutely nothing you can do with this screen short of making your self like it. I tried emailing you back for your return request but your for some reason i got postmaster replies. Honestly there is nothing wrong with your screen. You had already exchanged your z63a. It doesnt have a perfect screen but so far your about 1 in 100 that did not like it and could not deal with it. There was nothing wrong with the screen it was the same as the others like it. I gave that one to my brother in law. I figured if you were picky about screens then z70v would surely be the winner.....GUess not. For your next laptop go to best buy or any showroom and pick one out. 2 different screens (one that got alot of praise) and no luck i would say picky is an nderstatement but i am not judging. I am very used to this kind of thing by now. Thats why we have a no hassle exchange policy. I will be glad to send you a partial refund but i cant seem to reply to your email. Please check your inbox and email me back again. just need your confirmaton that you will take a 10% loss and i ll send the return label. You have 15 days from delivery to part with it but make sure its in original condition. Sorry it didnt work out.

 

Z71V is a completely different screen the only thing the same is the resolution. There is nothing perfect about any notebooks on the market. As long as that remains true there will always be someone who doesnt like a very popular and largely praised screen. I fully understand that. I can be picky my self about certain things.

 

the thing is i cant say anything bad about the notebook not even the screen its a great a screen. it just makes me ill looking at it its obviously me as other people dont have the issue.i cant help the way it makes me feel. but i really have no complaints about the notebook in fact it is better than i thought. just that issue i cant get passed

 

SRD seems to be sufering from some form of allergy.

He seems to have some real problem.Seek professional help.

 

Thanks lapboy thats some great advice. allergies wow wish i thought of that. I dont know why this particular display affects me. just like im sure people that cant look at crts effect them. or some people that look at the DLP tvs can see the rainbow effect from the color wheel in it. the thing makes me sick is that my fault no. did i want to keep this laptop yes. i just dont see the point of leaving dumb comments.

 

Hmm... have you tried playing with the colors yet, soften the tones? Perhaps there's something weird about the backlights tone itself?

 

Ive tried everything adjusting all the colors brightness gamma backlight level. something about the back light seems to effect my eyes. its feel like being in bad office lighting like when the certain flouresant lights bother your eyes alittle.

 

Doing a quick google it seems flourescents are common in laptop screens, which makes some sense due to the need to conserve power. That said the backlight could simply be faulty - as you see in many flourescents long before they die they can give off heavy flicker as gas escapes... just _maybe_ that's what's happening. Certainly this would give the sensation of a poor refresh rate.

Maybe you should show it to others for second opinions - if others agree I would think it to be faulty and worthy of a screen replacement. The light quality on mine is fantastic and I am certainly the type to notice and complain about something like this... I can't tolerate a refresh rate under 85 hz on my desktop 20" CRT.

 

I work in IT so ive used more monitors than anyone could imagine. I can tell you what the refresh of a crt is just by looking at it. Ive been using lcds since they first became popular and i have even used crap bottum of the barrel ones. I have never had the feeling i feel when looking at this. i cant say i can see it flicker but it does feel like a crt at a low refresh or like you put it flouressant lights when they are near dying they give that pale uncomfortable glow that makes you tired. im gonna have my friend take a look at it tonight he works in it to i havent even said to him anything about it. Im just gonna let him see my new laptop and see if he notices after 10 min. i had one other friend take a look she said it didnt make her sick or anything just felt strange looking at it she couldnt explain. i personly think it just seems to bother me which everyone is different so we will see.

 

OH and Beau10 i appreciate your responces. they seem to be more constructive than others. Im a picky person with anything electronic, cars etc i notice things that others would never notice but its more that i know about about electronics and most things so i know what to expect.i originaly ordered the z63a and it was great to but i did have the issue some w3v owners had the display didnt have a sweet spot it would invert colors just by a head nod. but its a 14.1 in screen limitation not a defect i know that. other pcs with the same screen size had the same issue so i returned it. this is not a case of me being picky its a sharp screen bright enough and good colors. i have to struggle just writing this email and im someone who could spend 10 hours straight looking at any monitor without blinking.

 

Not a prob, please keep the list updated on the issue until it's resolved. I started some threads over the past week or two on battery and keyboard issues myself, good to resolve these problems for the benefit of other customers. At this point I would put money on your screen being a lemon.

 

Well i had a friend use the pc for an hour tonight it didnt seem to bother him as much as me but he said it had a strange glow to the screen kinda had to try harder to view it then other laptops he had he felt kinda like double vision . but ive decided to return it for a 10% restocking fee. i dont want to go through the trouble of replacing the screen or something just to have the same problem because i feel its prob a good screen just doesnt agree with me for some reason. so i wouldnt be able to return it if i had the issue again. sucks though now i have no idea what pc to get? there really isnt anything similar at all maybe an acer but i dont want that garbage. im looking for something 7lbs and under with a 15.4in and is pentium M. there really arent that many to choose from that are good. im screwed
