X220 new IPS panels

Ok, just got my screen replaced.

Manufacturing date: 110820

Observations:

1. White point temp is slightly warmer. (Not an issue for me)
2. Backlight bleed is less on the bottom, now almost unnoticeable when the brightness is maxed, and the screen is black.

3. I can still make the screen ghost... Sorry to report this. The issue is MUCH reduced now, but in grey gradients, in high contrast situations, there will still be a slight ghosting issue.

At this point, I think I'm about done with this issue. It's hardly noticeable.

 

No need to apologize. Image persistence isn't exactly unique to the X220's IPS panel. It tends to happen (to varying extents) on many, many non-TN panels.

 

Well, whether or not this is the case, the only time I've ever experienced ghosting is with this specific LG panel. And I have a bunch of other various types of IPS and VA screens in my office here...

 

I've got a T43p that displays some image persistence as well as an (old) Dell IPS on my desk at work which has some *very* noticeable ghosting.

I will grant that it's a lot less common with most modern IPS/AFFS panels: the X220's is definitely an outlier in that it has noticeable image persistence yet is a new panel.

 

I just sent in my X220 for repair to resolve the light bleed issue (IPS panel on mine), and we'll see if I get one of the newer IPS panels. I'll report back on this.

 

Got my screen replaced. I concur with your observations on ghosting for the new panel.

 

How do you know if your screen has ghosting problem?

 

If you notice it, the screen have ghosting problem. If you don't notice it, there no need to worry it's not bothering you.

 

If you have to ask then don't worry about it at all!

 

Got my screen replaced, still suffers from the backlight bleed-through at the bottom. After reading more about it, turns out there's not much I can do.
