T440p 768p display upgrade to 1080p

#1 Post by Natakranta » Sat Apr 23, 2022 6:32 pm

Hi Guys, I've just got a T440p with malfunctioning 768p display - a dozen or more vertical lines over the screen. Do you know what eDP cable is with this screen? My blind guess is 30pin, right?
I'd like to replace it with FHD IPS screen, preferably with one of the low power (igzo ?) FHD displays from T490, I read once they can be retrofited as far as to T440p. Could you let me know model/type of these IGZO (if that's what they are called) to look for? Are they 30 or 40 pin? And what would be a FRU for eDP to match them in T440p.
I spent some time searching through the old threads, but I couldn't find anything relevant to my questions.

Edit:
T490s IGZO IPS Full-HD found on eBay, says 30 pin. Would that work to replace 768p display in my T440p. I don't mind missing brackets, I'll get some brackets stick to it, done that in my T480 4K mod few months ago.

I don't have a T440p, but a quick look at the T440p's FRU listing gives me one of its FHD panels, the LG LP140WF1-SPK1.
A quick web search shows that it's 30-pin, and based on image results, has the connector on the right side (looking from the rear of the screen).
The IGZO screen you linked to seems to have its connector at the same location.

Conclusion: there's a good chance it will work. :D
