The T420/T430 generally come with a 1366x768 HD screen. However, it is capable of using a higher resolution 1600x900 HD+ screen; the extra pixel density and vertical space is a game changer for programmers.
If you forgot to purchase the upgrade from Lenovo when you bought your computer, follow this guide to do so. However, the process requires quite a bit of disassembly, since the default HD cable must be replaced.
Note that both the HD and HD+ screens are both lame TN panels, and have the exact same viewing angles, colors and brightness.
If you want to try and install the X1 Carbon's beautiful panel instead, check out this guide. Unfortunately, with that mod the LCD cable has to be extended, so it's not practical for most people.
