a21p screen on t43

#1 Post by ggiglio » Wed Oct 11, 2017 8:14 am

My very first thinkpad was an A21p which sported a fantastic 1600x1200 screen that I still regret.
I was just wondering if I can install it on a 15" T43 (currently with a 1400x1050 panel).
Has anyone ever experienced such a mod ? And what about critical points (connectors, cables, video ram etc.).
Thanks

If you still have the A21p, get the model # of the screen from the label at the back of the panel, then search for its datasheet.

As long as the T43/T43p has an ATI-GPU, the 15" UXGA will work, if you also find the UXGA LCD-cable 91P6858.
SXGA+ and UXGA inverters are the same.
You can also put in a Sharp UXGA, see here: viewtopic.php?p=779362#p779362

Isn't the IDTech IAUX14S the better option here, if you can get such a panel in nice working condition that is. I got one with red backlight for $50 and stick a new backlight in, and it works well aside from some pressure marks from my questionable assembling skills. :lol: Though in a T4x you need some cable folding to make it connect properly.

It is.

That being said, it's a very nice panel for a TN. The very LCD that got me into higher resolutions some 15-16 years ago.

Now, I wouldn't swap a good IPS SXGA+ for a TN UXGA, but that's me.

I'm not sure how it compares to the W700s 400nit TN display. If it is atleast half as good, thats a [censored] good display right there. Probably similar to my X220's or T500's TN display, also a very nice TN display.

You being the FlexView farmer, I'd be worried if you didnt pick the IPS display over the UXGA first :D .
