W701 Screen Question

I recently ordered a W701 workstation from Lenovo. I chose the 1920x1200 RGB option. I noticed on the boot screen before any Windows 7 menus are loaded and while the screen is still dark, that when viewed from above at an extreme angle, the screen has what I would call patches that are darker than the rest of the screen. Those patches look a bit like slightly darker stains on the screen. These patches are present throughout the surface of the screen. When viewed from the front, i cannot notice these imperfections and the image is fine. As I said, this is not noticeable unless I view the screen from above, so my normal screen viewing is not affected.

Nevertheless, I would like to know is this is normal for this type of screen or whether I should worry.

 

I would not worry.

 

does it occur at the very start of the starting process?

 

I am able to see it when I start the computer because that is the only time when the screen is dark enough and these 'stains' are somewhat illuminated by the backlights. Once I am in Windows mostly everything has a white background or something similar so it cannot be observed.

I was thinking that this problem is not really a problem but an inherent part of the screen illumination, perhaps something to do with the RGB screen but I am not an expert.

 

can you take a picture of this? also put the laptop into black screen saver mode, and see whether you can see it after a while.

 

You gotta be kidding, right?

 

lead-org thank you for following up. I managed to take two pictures, although they are not very clear. It can be seen though, that the screen illumination is not entirely even when viewed from above.

 

Laptop TN LCD screens are not made for viewing from above, they made for viewing from the front. IPS technology-based screens being only rare exception. This Samsung panel is not IPS by any means, and it's quite angle-sensitive.
At weird angles you will see all kinds of weird artefacts, like backlight unevenness, gamma, extreme color shift or even inversion, etc. I don't see how this can alarm - after all, you subjecting screen to out-of-spec viewing conditions.
At such extreme angle you are starting to see bottom backlight strip directly refracted in front polarizer, instead of seeing reflection of it through backside diffuser. Hence the blotchiness (due to it being made of several discrete LED elements). At normal viewing angles you are not even seeing this light, so nothing to worry about.

 

that is normal, laptop LCD uses edge lighting rather than direct backlighting, so inconsistent in backlight is quite common.

 

Also I noticed that you have a pixel that is out as well (I was able to notice it on both photos (in the center of the screen, about 1.5-2 inches down. It's a TINY red "dot". I THINK that's a dead pixel).

I noticed it because back in the day, I bought a Compaq laptop. I must have bought it back 4 different times for new ones because each new laptop had at LEAST 3-4 dead pixels in the screen. That would drive me MAD.

Not trying to be a ____, just wanting to point it out to ya (unless I'm mistaken, anyone else notice it too ??)

 

Thank you lead_org and everyone else for the advice.

The dead pixels are actually coming from my camera, which is old, has dirty lens and a few scratches.

 

Ahh, cool ! (well, not cool, but you know lol).

Congrats on the W701 ! A 17" Thinkpad is next on my "Thinkpad Wishlist"

 

Thank you. And if you ever get the W701, enjoy.
