Non-"s" 2560x1440 QHD WQHD - any news?

#1 Post by mydreamlaptop » Tue Jan 22, 2019 6:50 am

I did the 1920x1080 FHD mod a few months ago but it still isn't quite enough pixels for me.
Any updates on the 2560x1440 ("QHD"/"WQHD") mod for T420/T430 Non-"s" availability in the U.S.?
Last I checked there was:
1. Apparently soldered kit made by 51nb member KingKongLue (who also goes by K.K) but only offers preassembled motherboard or whole machine.
2. Alternatively one that uses the LVDS claimed to be in development by others.

I may be willing to risk ruining a motherboard or two for me to practice soldering.

Making an offer on the e-qstore listing. Looks like it's LVDS.
I don't know how they get around the LVDS bandwidth limitation, maybe using 18-bit color instead of 24-bit.
We shall see...

If I hadn't already built my T430s with the javi-jie wqhd kit (that I enjoy very much) I'd order this for my old T430 in a heartbeat. :cry:

Now that the screen options are equal, the only practical advantage a T430s has over T430 is the slimness. While fatter and slightly heavier, T430 can take bigger batteries and quad cores CPUs. I envision a new project pad in my future...

Screen is probably the best upgrade. :)
So how are people doing this mod on other Thinkpads sourcing their 14" 1440p screens?
When I did the 1080p mod I went on eBay and almost instantly found a used exact model screen pulled from a Dell, from a US seller with great feedback.

But with the 1440p I can't seem to find any reasonable listings for exact models, it's all "compatible", "varies with stock" etc.

Well, more than "slightly" heavier, IMO... Especially with those larger batteries. :) But, yeah, for someone who does not care about the weight, a T430 can make a much more capable and expandable workstation.
