Pics of T60 WS light uneven backlighting/screen weirdness

Is this what others are seeing? Is this the light "leakage" issue?

Pic #1 - shot of the blank screen saver, screen perpendicular to the camera (camera on tripod). Notice the uneven lighting especially at the bottom. Lights were out in the room, so no reflections. From the thumbnail, it looks like the band at the bottom is the task bar. It is not! It is extra brightness at the bottom.

Pic #2 - shot of a dead-pixel test screen, lower left corner of the screen. Notice the brightness drop-off towards the top. (black and white pattern)

Pic #3 - shot of a the same dead-pixel test screen, upper left corner. Notice the drop off towards the bottom (though not as bad as towards the top)


edit: I mangled the title of the post.

 

that's impossible! ibm makes the worlds best laptops how could the screen not be good :S. i even ordered one and if i get that i will be mighty pissed. therefore, i believe that what you have posted is a prank! rooooooar

 

I do have exact same problem of light leakage with my T60 WS. But I dont have dead pix.

 

pmc123, I'd be happy to take pics of my Z61M Samsung screen so that we can compare. I don't think I have the same issues as you, but I'd like to see how it looks when looking at pics taken on the exact same tests.

1. Blank screen saver, dark room, no flash, right?
2. Where can I get the software you used for pics 2 & 3?
3. So you took pics of the lower right quadrant and upper right quadrant, correct? In a dark room with no flash, correct?
4. I haven't posted pics on this forum before...did you host them on a picture hosting site and link to them or can you attach them to this forum directly from your computer?

Please give me any additional details you can and I will try to replicate exactly what you have done to help you get to the bottom of this. Alternatively, perhaps you could just set your desktop background picture to "none" and then choose "white" as the color, hide the taskbar (drag it down) and take pics of a white screen that way? If you can post those pics, I can do the same and we can compare that way. That would be easier than me installing software and trying to get the same screens.

 

Hi jkozlow3,
I used a DSLR, dark room, no flash, on a tripod, lens perpendicular to the screen. F2.5, 1/30 second, ISO 400.
1. correct - blank screen saver.
2. The dead pixel test was just a web page with different patterns. Nothing to install This is the site. Scroll down about midway in the page. The one I used was "Black&White" under "Normal".
3. actually I typed it wrong in the original post - it was the upper and lower left quadrants. I'm directionally impaired I think
4. I just attached them directly to the post. There is a button on the new thread window that says "Manage Attachments". Fairly straight forward from there.
In fact, I did try with a black desktop and the toolbar hidden, but there is still a tiny portion of the toolbar that shows and the brightness kinda masks the problem. I tried putting the toolbar at the top too, but finally decided the blank screensaver was the best way to go.

 

OK, my pics with my point and shoot came out pretty crappy. I tried auto mode as well as manual modes. I think I need some lessons in photography!

Anyway, I'm not sure the pics are good enough to show anything really. I don't think my screen is as bad as the pics you posted, but I did notice some variance from picture to picture.

Here's 1 pic of the black sceen with some light leakage. It didn't come out nearly as well as yours (no tripod, F stops, etc), but I don't think my light leakage is very bad.

 

I think any lcd backlighting uneveness is unacceptable on a $~2000 machine. I'm contacting lenovo tomorrow. I'll let you know what the outcome is.

 

hmm, this is common...
It's very hard to prevent and can be found in pretty much any LCD monitor for desktops. And laptop displays are much worse so if there weren't any backlight leakage I'd be quite surprised. Of course the amount varies alot but there are bound to be some leakage, especially (I've come to suspect) on the bottom of laptop displays.
LED displays doesn't suffer from this I guess but they are not common.

Also taking pictures of this is quite hard and the outcome is only compareable to the exact same camera and light setup. Otherwise they are quite useless.

Also, do thinkpads really have that great monitors?
Mine does not and I know of quite a few tests that have come to the same conclusion.

Of course there are the superbright monitor or whatever lenovo is calling it that is much better but you have to pay quite a bit for it.

I read a test of laptops and in their test I think only Sony had good displays. While pretty much all others (including thinkpad) didn't.

EDIT:
I'm not saying that your monitor is fine, but it's impossible to tell from your pictures.
The second pic. doesn't seem to be perpendicular to the screen which would explain the gradient. Also you can't take photos close to the screen, the bad viewing angles will screw up the images.

 

Sorry to hear about the problems you are having. I have a T60 ws 8741-49u and I couldn't be happier with it. I think that it is better than the T41 that I had. My only compliant is that **** high pitched noise. I doubt Lenovo will exchange your notebook but I would suspect your could get it replaced under warranty.
Good luck,
Scott

EDIT:
I get a kick out of what they sensor. darn high pitched noise.

 

Why yours is only 5.5lb, but my 87445bu is 6.2lbs? The specs look almost the same! And yours is Samsung panel or LG/Philips panel?

 

My screen is
Mfg part # FRU part #
13N7019 13N7020

I would guess my T60 is around 6 pounds. It's lighter than my MSI 1029 and that's about 6.5 pounds.

= LG/Philips screen

 

Thank you...My screen has minimal light leakage. Like I said I'm very pleased with my T60.

pmc123, how did you make out with Lenovo?
