I am going to take a dive and swap an IPS screen from a lesser X220i into my other X220.

1. I have expressed my concern elsewhere (http://forum.thinkpads.com/viewtopic.php?f=43&t=99779) about the low-brightness of the IPS screen and the creamy/yellowy tinge - are these the norm? the brightness seems a lot lower than my current TN and at max 15, it is the equivalent of the TN's 11-12. But at least there is no ghosting or visible bleed as some have reported.

2. Is that a straightforward physical swap? The HMM seems to suggest so - it appears the different LCD's all use the same connector (a 40-pin one?).

Pls let me have your opinion as tomorrow is a public holiday over here and I was planning the swap then, rather than be at the beach!

The IPS screen is rated at 300 nits while the TN screen is rated at 200 nits, which is about average for a notebook screen. I haven't noticed any yellow or creamy tone on my X220i.

My guess would be it's a straight swap. They use the same cable and tend not to re-invent the wheel, but I suppose you won't know until you open it.

Fred, thx for your opinion.

For what's it's worth, I have this morning done the swap, which is in fairness quite straightforward and everything fell in place nicely; one just needs to be careful with the bezel so as not to break the clips - but the x220 is a marked improvement over previous models when it comes to disassembly and reassembly.

As regards my yellowish tinge, I have played a lot with the colour enhancements page in Intel HD settings and I have been able to get something closer to my liking, so my whites look whiter and not creamy but I just wished that a 300-NIT screen would have a colder colour temperature and be a bit brighter - although I know IPS is not as efficient as TN in terms of light transmission.

I can therefore now confirm that the IPS/TN swap is a simple conversion . The x220i is on the other hand happily running fine with its TN panel too
