Honestly the screen isn't so shit when you understand it's a 2012 era machine and get used to it. For comparison i had 2022 gayming laptop that had a terrible (45% NTSC~) screen which was so much more noticeable.

The only reason to go down the upgrade path of
>chink 1080p adapter (35$)
>FHD panel that fits your adapter (75$)
>100W type C to barrel plug (10$)
>chink 6 cell or extended 9cell battery
>maybe an upgrade to the i7 since it's a socketed CPU

Is if you *really* want the classic T420 thiccbox typing experience or already have one. Otherwise you might as well grab a cheap T490/495 or T14/P14 gen1/2 with one of the better display panels for about an equal investment.
