T420 with some big combination of LCD parts.

#1 Post by Thinkpad4by3 » Sat Dec 09, 2017 4:26 pm

Ok, could I frankenstein something together working with the following parts?

T420 base w/ 768p panel
T430s 1600x900 panel
T410 LCD cable 1280x800p (tested to work on T430s panel)
Thinkpad4by3's Law of the Universe.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

Assuming pinouts are all the same:

I highly doubt that the T410's 1280x800 1 channel 6 bit cable will work with the T430s' 1600x900 2 channel 6 bit panel. You'd get the same display errors as using a T420's HD cable with an HD+ panel.

If it works 100%, all the pixels and colors look correct, then it's possible you actually have a T410's 1440x900 2 channel 6 bit cable, which would drive the T430s' 1600x900.

If you need a cheap 2 channel 6 bit cable from a fast-shipping domestic seller look into getting a T410s cable, because all T410s' used 1440x900 2 channel 6 bit LCDs and the connectors at the motherboard and the LCD are the same as the normal T420 / T430 panels. You will have to modify the tape going around the T410s' cable to get it routed correctly to fit in a T420, but it should be possible without mangling the wires.


EDIT: T410S CABLES ARE DIFFERENT DO NOT BUY
