X201t screen calibration

[fdeutschmann]

Hi all,
My X201tablet screen gets fairly misaligned with the stylus, especially near the edges. The screen calibration tool works, but doesn't seem to work well. I've seen instructions for using a tool that allows multiple calibration spots (beyond the normal 4 locations), but I haven't been able to make this work on the X201t; can anyone tell me if it is possible to get more calibration points for the X201t? Alternatively, are there any recommendations for how to improve the calibration of the X201t screen?

[AndreR on the notebookreview forum pointed me here, specifically to the Asus drivers, but I can't find them; can anyone clarify this?]

Thanks!!

If you go into the control panel - Tablet PC settings

reset the calibation for the pen and then calibrate you get 16 points.

Thanks - but I tried this just now and I only get four points.... Any further advice? Do I need to update a driver, etc?

Vista: Calibrate Your Tablet/Touchscreen With More Points Carlo Mendoza

Try this. You should be able to just copy his commands as the grid values are made for 1280x800. You can freely choose the values, they just represent the offset of the lines from the screen edge.

Hattori, thanks for your (quick!) reply. But... First, when I look in the registry, I don't see the key indicated in those posts: I don't have any keys relating to linearity under HKCU\...\TabletPC, and under HKLM\...\TabletPC\UserLinearityData there are a pair of zero-length binary values. When I try to run tabcal from the command line, I get the error that "linearity data is already present"; if I delete it, I don't see any change in the registry values (even after refresh), though the tabcal tool does work. BUT, it still only calibrates to the same four points.....

Seems to me this has to be a driver issue, but which one???? I'm using ISDTablet (Wacom, v7.0.2-19), sourced from the Lenovo site -- at least that's the driver I un/re-install when the cursor goes nuts....

Thanks for any help!

Hmmm, then do you have the ISD tablet icon in the control panel?
There's possibly an option there to delete the currently stored linearity data or use a different calibration tool.

I currently have that ISD driver from Wacom installed nowhere to check that myself :-/

I had problems and ended up using the following

Touch driver 3.07.13 - Wacom

Cant find this version on web but HP have an update.

HP EliteBook 2760p Tablet PC- Download drivers and software - HP Business Support Center

Choose 32/64bit

I uninstalled the Touch Driver that was there and replaced with this one.
