X220T Pen Input Screen Edge Sensitivity?

I'm assuming you used the method here: Vista: Calibrate Your Tablet/Touchscreen With More Points Carlo Mendoza

Damn, that is a good tip!
Unless everybody except me knows it already, this should be made public here!

I'm half engineer, half computer scientist and half jurist. I can't have a laugh without filling in form "Humor 29847/C with appendices 29800 A and F" and having it filed

I didn't know this....interesting....I need to give this a try!

[LastQ]

Nice!

I used these values for the calibration and it seems to work really well:

tabcal lincal novalidate XGridPts=5,275,547,818,1089,1360 YGridPts=5,156,308,459,611,763

Funny how you have to do this to get some good calibration, the 4 pt is obviously insufficient.

Wow, this helped a lot, thanks! However, it's still very unprecise at the edges. What about adding more calibration points there?

@ Kaffeemann
You should now see how this works

[Kaffeemann]

In fact I´m just too lazy to try it myself

Any improvement at teh edges with the new calibrationn method?

Anyone else had any luck with screen edge issues by calibrating? Even using the points above with tons at the edge has made zero difference for me, 1.5cm around the edge completely unusable. After waiting 2 months for this thing to arrive I`m really disappointed... Bought it for note-taking, and now a big chunk of the display in portrait mode is useless... even worse as they made it 16:9.

[randfee]

could you take a video of that or give us an estimate on how large the offset is? Have you talked to the lenovo support?

[strife502]

Not a video, but you can get a pretty good idea from these pictures - sorry about quality. Have yet to contact tech support but will be doing so today when I have time.

All sides do this except the top edge (where camera is) which works perfectly for some reason. It is especially bad at the corners.

[randfee]

omg... is the tip touching the screen on these? This is awful indeed, I wouldn't accept this!
Have you tried the original wacom drivers?
Did you calibrate the screen with holding the stylus in the same angle as it appears on the images here?
