Replacing T430 screen with a better one
Thinkpad T430 laptops (as well as T430s, T420 and T420s) are equipped with awful screens. No matter if the screen is HD (1366x768) or HD+ (1600x900) and no matter if the screen manufacturer is LG, Samsung or AUO: every screen has been reported to show awful viewing angles, poor colors and weak brightness.
The subject of upgrading the screens of these laptops has been long discussed on forums, notably on Notebook Review Forum at the thread "X1 display on a T430?" and on ThinkPad-Forum at the thread "T420/T430 auf FHD-Panel umrüsten (wie Alienware 14" FHD matt) ... Gibt's schon Infos?". More than one screen has been considered as candidate for the replacement, nevertheless at this time (November 2013) it seems that only the X1 screen has been successfully installed.
At this time the principal aim of this article is to describe the successful installation of the X1 screen on my T430. Nevertheless, thanks to similarities between T430, T430s, T420 and T420s the information hereby presented could be applied to these other models too. Moreover, I've summarized some information available about one other panel considered as replacement so far. The article itself is written in order to be improved with future discoveries on the subject: any future contribution will be welcome!

The one of X1 Carbon

The HD+ display mounted on X1 Carbon is a 14 inches TN screen made by LG. This screen has been praised by reviewers3: it features good viewing angles, rich colors and high brightness. An interesting comparison between this screen and one of the awful screens mounted on T430 has been published by Laptop Reviews: "Thinkpad X1 Carbon screen comparison to other Thinkpads".
Talking about compatibility, this screen has the right connector (40-pin LVDS) and the right dimensions to fit perfectly in the T430. Besides, it can't be screwed (the original is screwed) and, most important, its connector is on the wrong side (on the right instead of left). In the following solutions for these problems will be presented.
The X1 screen can be purchased straight from Lenovo or from third parts for quite less money.
The one of T440p/T440s
T440p and T440s feature excellent IPS panels (HD+ and Full-HD), that by definition should be superior also to the screen mounted on X1 Carbon. They've been reported to have same dimensions but completely different connectors (eDP instead of LVDS). No consistent solution to this problem seems to have been put forward.
Swapping the LCD cable (if necessary)

If your screen is HD (1366x768) then your LCD cable is HD as well. In order to make an HD+ panel work in your T430 (the panel of X1 Carbon is HD+), you have to substitute also the LCD cable with an HD+ LCD cable. This isn't a trivial task: to do so it is necessary to remove, among the others, the keyboard and the keyboard bezel assembly. If you're a bit practical with this sort of things, it would take approximately 40 minutes. If this would be your first time opening something, maybe you should ask someone to help.
Instruction for replacing the LCD cable can be found on Lenovo website: "LCD panel and LCD cable removal and installation - ThinkPad T430 and T430i". As one proceed it'll be clear that some minor parts which are requested to be removed can actually be left unmoved (e.g. speaker assembly, LCD unit and integrated camera)
Removing the old screen
Removing the old screen just take five minutes. After having disconnected the power cord and battery, remove the bezel by pulling it from the interior edge (the edge that is in direct contact with the screen) using your nails. That's may be not one's natural approach, but Lenovo advised so, and doing the contrary is terribly difficult. Once the bezel has been removed, just unscrew the panel (it is fixed by four standard Phillips screws), and place it upside down on the keyboard. From this position you can now easily disconnect the LCD cable. Now, you will be probably tempted by finally crashing that awful screen onto the wall, but wait: keep it, in order not to invalidate the warranty. It's indeed my opinion that, if you swap back the original screen, you won't leave any significant trace of your hacking.
Extending the LCD cable
The cable connector of X1 Carbon panel is in the wrong position: on the right instead of left. In order to connect the panel to the LCD cable is therefore necessary an extension.
Many models of LCD cable extension can be found on the internet, but unfortunately the most spread were showed unfit for our application. Just one model has been proved to work after some important mods, nevertheless it is possible that one other model would work with no mods. In the follwing these three models and their installation are described.
