That's great news, would we be able to have the part ID of the new screen?

Mark,

 

Thank you and the rest of the team for a great job!

 

A couple of questions though:

 

1) Can you please elaborate on the different specs between the old and the new panels? Is there any technical info?

 

2) If I were to order a new X220 now, how can I make sure that I get the new panel?

 

Best regards,

Alex.

I'm not sure whether my X220i has the new panel. I have noticed image persistance, but it was very faint and it only happened after several hours of having the same content displayed. In my opinion the issue is negligable, at least on my laptop.

 

If you are debating whether to get the IPS display, don't. It is hands-down the best display you can get on an affordable laptop right now.

I'm actually not fully sure if my panel is the new IPS panel either (X220 was manufactured early to mid August.

I haven't noticed any image persistence however I definitely notice a change of contrast (and the Dynamic contrast control is off in the Intel Graphics settings).

For example when I am watching a movie in full screen, then I switch to the desktop; the desktop will look washed out for about 10 seconds or so then slowly return to normal. Not a huge issue compared to image persistence, but still enough to be a little annoying in everyday usage.

I can not see your attached picture

 

@jeff3yan

 

In "battery mode" there is another checkbox under dynamic contrast. Have you seen it ?

@Mark

That is great news. Thank you, and send a "thanks" to whoever finally decided to man-up to this problem at Lenovo.

I honestly like everything about my x220t's except for their bad image persistence. I'm glad to know that I will be able to get properly working screens.

That's thanks to the crappy forum software -- you have to be signed in to see hosted images (or you just get a singularly unhelpful error triangle image), and even then you may have to force a full refresh of the page to see it (because page age isn't maintained properly). I've now switched the image to external hosting to avoid the sign in problem, but you may still have to force a full refresh of the page (Ctrl+F5) to see it.

Ok i see it now.

 

I was talking about this checkbox : "Technologie de réduction du courant consomé par l'écran" ;)

That's what make my screen brightness/contrast (not only backlight) vary in real time when i was on battery. (It was enabled by default) and sometime it make the screen look dull

In English that's Automatic display brightness (not contrast), not enabled by default (on my system at least).

What display driver are you using? I'm using Lenovo-supplied 8.15.10.2342 (3/25/2011).
