I noticed the Ghosting on my X220Tablet 4294CTO for the first time after doing a 75 minute system restore with Rescue & Recovery. The outline was so obvious that I noticed it without having to look for it. I also notice it when looking at images or pictures for any significant period of time. I heard about this problem being common in monitors before I was born... Never imagined I would experience it myself. Wow!!! it's like I opened a time capsule to another era.
In all seriousness though:
Lenovo,
Can you imagine if a radiologist, pathologist or other physician is viewing images from his/her laptop at home (not terribly uncommon) and the laptop happens to be this Lenovo X220? (again not uncommon, lenovos seem to be well represented at my hospital anyways) I know it's unlikely but the ghosting might cause someone to miss or over read something. This is particularly problematic if they are looking at a string of the same types of images (For example, a physician running through all the past EKG's or CXR's from home or their office to make sure they have a interpretation on record in the hospital computer system).
At the very least, a shadow here or there might raise an eyebrow or be annoying to the physician. If you're not going to fix it fine. I get it. It costs too much to solve this problem. But maybe put it in the manual (or other literature) that the screen is prone to ghosting and that this is "normal" for the screen. That way consumers can properly decide whether the product you are selling (flaws included, they are flaws stop denying it) is something that fits their needs.

(As a lowly medical student even I find the ghosting annoying particularly if I'm reviewing radiological anatomy on an XR for several minutes or if I leave an XR on my screen for more than 20 minutes).
