8204 grey lines on LCD

Thread Starter 
Hi I previously reported on this problem here:
http://forum.notebookreview.com/show...70#post1270370

..but thought I'd post it here since there seem to be alot of 8204 users and I was wondering if you could confirm if you have the same problem as me. Basically on the LCD every 2nd row of pixels horizontally is greyer than it should be.

Powerbooks had the same problem and Apple have begun replacing screens:
http://forums.macrumors.com/showthre...158751&page=55

This is the test to try if you are unsure if your screen has it: Go here http://www.crankycat.com/ and look at the blue box on the right side of the page. This picture has grey lines every 2nd row of pixels - if you look at it on another display you will see them. Now on your 8204 grab the scroll bar and scroll the page up and down a few pixels - notice when you scroll it a few pixels you can get the image to become clear. This is because the grey lines on the 8204's LCD compensate for the grey lines in the image and the result is a clear image with no visible lines.

Everyone else got this? Think Acer would take action like Apple did?

Another test:
http://www.cameraid.com/art/quadrants.gif

The top 2 quadrants are the same brightness on a normal display, but on my 8204 they differ.

Can't see anything on the Crankycat but on the cameraid I have 4 distinct quadrants and the top 2 are different in brightness but when I switch to the external monitor the top seems just like it is 1 section.

My 8204 has the same problem, ruins the machine for me as it makes the screen tiring to read and soft, hence being returned on Monday. Does anyone have a machine wihtout this problem as if so i may try another. My LCD is Samsung LTN154P1-L02 machine build date 01/06

What I don't understand is what is the problem? If we can only see it on those pages it's really not a big deal to me. I don't notice it at all unless I do that test.

If you dont notice it then I guess it doesnt matter. But for me I clearly see the rows of grey lines and they distract me in everything I'm doing, especially in movies and games. Even on the grey background in this forum the grey lines are clearly present. Its like my display is dithered.

I got the same issue - RMA'd once, the Acer maintenance said they have the issue on their reference laptop as well, so they didn't do anything about it. I would be very interested in hearing if you got a new screen as a replacement.

The issue is so clear, you'd have to be blind not to see it. Basically, alternating brightness levels every other pixel row. I noticed it the moment I finished the Windows installation - and no, I don't get used to it.

I sent mine back asking for either QDS003D or another model without the problem. I'll let you know what it's like when I get it back.

Maybe there's some way of darkening all of the lines which aren't dark...but then again, the screen is already dim so I don't know whether that is a solution.

****, Acer techs are as crap as everyone says. I received my laptop back today and although the LCD has been replaced, it's the exact same faulty model - the LTN154P1-L02.

I'll phone them and see what they say...

I'm assuming you are still getting the grey lines with the replaced screen?

Just as a data point my 8204 has a manufacture date of 0602 and has the Samsung screen but NO grey lines, uneven colors, splotches, or whatever. I've examined the screen with a 10X loupe and besides being dimmer than it should be on a laptop of this cost has no quality issues at all.

Second it's interesting that people say the new MacBook Pros have the same problems, meaning they are using the same screen model. Everyone who sees one remarks on how bright the MBP screen is, which could mean our "dimness" problem is really a settings issue which could possibly be fixed by an update. Hope springs eternal...
