raingrove Posted May 22, 2006 Share Posted May 22, 2006 Guys, please go here: http://raingrove.net/mbp.html and take a simple test for your LCD screen.. Do you notice the pulsating screen on the left side? Mine does... If you notice the problem, please digg it, so that more people will hear about it.

Timyang Posted May 22, 2006 Share Posted May 22, 2006 Ouch! My 3-year old Dell laptop is showing flickering, but I thought it was normal before... Link to comment Share on other sites More sharing options...
staticuxo Posted May 22, 2006 Share Posted May 22, 2006 weird. how'd you find that out? mine blinks on that page. i've not noticed a problem anywhere else though... Link to comment Share on other sites More sharing options...
raingrove Posted May 22, 2006 Author Share Posted May 22, 2006 It seems like a (yet another) problem with the LCD inverter, I am not too sure... but nonetheless it is not something I would expect from a $2.5k "professional" notebook that I use for graphics design and stuff.. Please digg the page if you don't mind. Thanks. Link to comment Share on other sites More sharing options...
munky Posted May 22, 2006 Share Posted May 22, 2006 uhh.. my 12'' powerbook g4 1.33ghz is flickering (well, more like shimmering) on left AND right on that page. i think its just moire effect, and will probably affect most if not all notebook screens.

quixos Posted May 22, 2006 Share Posted May 22, 2006 i think the page is a hoax. someone find a way to download that background gif. it does the same thing on my non macbook lcd. and on no other page or situation has it done this. Link to comment Share on other sites More sharing options...
raingrove Posted May 22, 2006 Author Share Posted May 22, 2006 it's not a hoax. the URL for the background image is http://raingrove.net/bg.gif ... btw the flicker also happens on my cheapo Acer, but not on my LG LCD Link to comment Share on other sites More sharing options...
quixos Posted May 22, 2006 Share Posted May 22, 2006 a blank screen? where is the background image? by the way, this isn't some sort of personal attack on you. if i'm wrong, i'm simply wrong. Link to comment Share on other sites More sharing options...
raingrove Posted May 22, 2006 Author Share Posted May 22, 2006 It's a tiny 2 by 2 pixel image...not a BLANK image. Link to comment Share on other sites More sharing options...
quixos Posted May 22, 2006 Share Posted May 22, 2006 oh please right back at you. thanks for pointing it out though. i i guess it is that moire effect. i'll edit my post above to reflect the fact that i didn't understand what i was talking about.

raingrove Posted May 22, 2006 Author Share Posted May 22, 2006 i got that image off http://www.fandango.com/ Link to comment Share on other sites More sharing options...
quixos Posted May 22, 2006 Share Posted May 22, 2006 i don't think it's a macbook problem so much as that image and lcds don't like each other. really didn't want to appear in attack mode, but it was the oddest thing to see, and i have no problems with my lcd so i assumed it was a purposeful misdirection. no hard feelings i hope. setting it as my desktop background tiled, the same thing. interesting.

Swad Posted May 22, 2006 Share Posted May 22, 2006 Is there any way for us to reproduce that effect to show non-MBP owners? Link to comment Share on other sites More sharing options...
raingrove Posted May 22, 2006 Author Share Posted May 22, 2006 Well, cheap LCD screens seem to exhibit the same problem. Some MBP users pointed out that their screen doesnt have the flicker though. But majority, including all my friends seem to have the flicker... Basically...the left part of the screen will blink.. on 50% fill patterns of high contrast. Quixos> i am cool.

quietglow Posted May 22, 2006 Share Posted May 22, 2006 FWIW, I get no flicker on my laptop (see sig). It doesn't get really hot either. And now it has an apple on the lid too (but you can peel it off) :-) Just don't ask me to start it in target disk mode. Link to comment Share on other sites More sharing options...
-TiLT- Posted May 22, 2006 Share Posted May 22, 2006 Just tested on ma MBP and there is flickering. But it depends how I look on the display. It is never at the point where I look at, only in the outer parts of my range of vision. I think what we are experiencing here has something to do with humans eyes. Our visual organ is evolutionary developed to produce maximum sharpnes in a small angle (1-2°) in the middle of the range of vision, but to have a faster response for movements in the outer range of vision. The reason is simply to have a faster response when something attacks from the side. The image set as the background of the testpage might propably hit the point where LCDs electronic gets in trouble and their refresh rate becomes viewable by humans outer range of vision. Maybe I am totally wrong Link to comment Share on other sites More sharing options...
Chrysaor Posted May 22, 2006 Share Posted May 22, 2006 No flickering on my laptop. Specs in sig. Link to comment Share on other sites More sharing options...
quixos Posted May 22, 2006 Share Posted May 22, 2006 i changed my LCD refresh rate from 60 Hertz, to 75 and that removed the oddness. Link to comment Share on other sites More sharing options...
Ouch Posted May 23, 2006 Share Posted May 23, 2006 It's an optical effect - i think caused by the inability of your eyes to focus on all the dots at the same time so as you try to focus on a small area the area at the periphery of your vision is out of focus and appears to flicker.
