Tired of the awful OEM screen on your T420? Want FHD (1920×1080) resolution with the full colors and deep blacks of IPS screens? Having a hard time deciding which to order? Then this page might help you.<\/p>\n

There are several screens available for the non-S T420 laptop which have performance characteristics on par with true IPS screens. This page<\/a> has a good explanation of how the various panel types differ.<\/p>\n

This thread by RMSMajestic<\/a> seems to be the origin of the screen upgrade for the non-S Thinkpad T420 and T430. The first post explains why flickering is a common problem.<\/p>\n

There are several eBay sellers carrying FHD IPS controllers. The one sold by moe-tech<\/a>, for example, supports the following screens:<\/p>\n

There are also 40-pin controllers that support 2560×1440, such as this one by e-qstore<\/a>. It lists the following screens:<\/p>\n

I chose the AUO B140HAN01.3 from eBay seller neidersch, and the LCD controller from moe-tech. Why that particular screen? Because I wanted a matte finish, and it appears to be identical to the B140HAN01.1, aside from being 0.2mm shallower. Both have been working great for around nine months.<\/strong><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
