How is the t440s screen? I heard that for some light bleed bad view angles

How is the t440s screen?

I read that lenovo at some point stopped using the good screens they had before and switched to cheaper screens

"The screen I actually got was quite different. Immediately, I noticed huge light bleed, terrible viewing angles, bad colour, screen door effect, etc. It was in fact a worse viewing experience than on my cheap 1366x768 VAIO.

Some quick googling brought up the reason: For some units, Lenovo ran out of the original good-quality AUO-manufactured screens (the ones that were reviewed), and substituted it with an inferior LG-made screen. The BIOS on the T440s confirmed that my unit had the LG screen. Bad luck."

There used to be a screen lottery (AUO vs. LG) for quite some time when these laptops were first introduced. Whether it's still going on is anyone's guess.

If you end up hating the screen, you can always return the machine.

Good luck.

 

I had the LG panel on my T440p and replaced it with the AUO panel (due to excessive light bleed). Both screens are very good for a laptop (the LG is IPS and the AUO is AHVA) and are in a different league to a 1366x768 TN panel in terms of brightness, viewing angles and color accuracy, so put all the complaints in perspective. I never really noticed the screen door effect on the LG for the few days I had it and the light bleed is less to do with the panel than the way the lid is assembled.

 

When I go on the lenovo website to order it, there does not seem to be a way to select AUO vs. LG)

AUO is better right? In general, if you wanted the better option in this case who would be the person to talk to or thing to do if you don't want to do what other people did: (buy it, find out after the fact it was bad, call, return, etc) just to avoid that hassle?

 

>> to do with the panel than the way the lid is assembled.

If you had that problem what is the best solution?

The lid is slightly open right? If I get a device like that what is the best option? I can't fix the lid myself can I? Superglue? Return the device?-> How could I ever prove that the device was faulty as opposed to me damaging the device?

Do you ever videotape yourself unboxing the device just to prove that a defect is a defect and not your damaging the device? Idk how to strap a smartphone camera to my head- that'd make it easier.

 

Because there isn't.

No one can guarantee what screen you'll receive. Period.

That's why I've previously referred to the process as "screen lottery".

 

Huh? My comment about the lid was specific to the T440p, which I requested repaired on day 1 of ownership when I started it up and saw huge patches of light bleed visible even after startup. I simply upgraded my warranty to onsite (as i planned to do anyway) then called Lenovo and reported the screen and fan faults. The problem with the lid I refer to is about the inherent stiffness of the design (or lack thereof), so it's nothing "fixable".

The T440s lid is supposedly stiffer than that of the T440p, but watching the tech take the lid apart I understood how pressure could build up on the edges of the LCD panel to cause light bleed -- there is no bracing inside the lid to speak of, so any flex from opening and closing is likely transferred to the frame of the LCD panel to some degree. I suspect this is also the case for the T440s, although the lid composite is perhaps inherently stiffer thanks to its carbon fiber reinforcement.

The AUO panel that was installed in my machine was perfect the first month or so -- zero light bleed detectable on startup. Within a few months there were already 2-3 patches of mild light bleed visible on start up, so it's been deteriorating and I find it hard to believe the LCD panel spontaneously does this without pressure being applied by lid flex. Hopefully it will not get worse.
