Help upgrading Thinkpad T490 panel (kbin.social)

Ok, I'm a bit of a noob when it comes to hardware stuff. I have a Thinkpad T490 with the 1920x1080 non-touch screen. My complaint is that I ended up with the model with only 45% NTSC. I would like to upgrade to something with 72%.

AFAICT, my screen's model # is N140HCA-EAC. 30-pin connector. Is this - https://www.laptopscreen.com/English/model/Lenovo/FRU~01YN154/ compatible?

I already know there's no blocks or whatever in the bios preventing an upgrade, just want to make sure I buy the right thing. Would rather not ship from China so NA sellers are good.

(btw I obtained the model of what I have now by running "edid-decode </sys/class/drm/card0-eDP-1/edid", I'm on Linux)

Yes, I think so. I the T495 is - as far as I know - just the AMD version of the T490.

I think it's ok that you can't find the revision of your screen. Just check the different revisions on panelook. I suspect they'll match in dimensions and connector position. I Mena, they ought to, as they are the same model number, and the revision apparently is so unimportant that it doesn't get stated by the screen itself.
