Finally, think I did everything correctly and I have to say it DID improve the overall accuracy. Managed to decrease a few milliliters off of the edge drift!

One last thing: Why do we need to backup those files after-all? Just in case something goes bad with the calibration settings OR for when we update the Feel drivers, so we can replace them back, for instance?
[Microsoft Surface] xiaohang.07:
In case you recovery your system to a former state, or you reset your system. By the way, I do experience a setback once, just a few days ago. I find that the accuracy is low even in central region. Then I guess that it is probably the ISD_Tablet.dat file having some problem. After I copy the content of my backup ISD_Tablet.dat file to the one in ...AppData/Roaming/WTablet folder and save, I restart the surface. Bingo, everything is back to normal again. I just don't know what happened to that file at that time. But it only occurred to me once. So it is not a problem.

In fact, it is the Microsoft and Wacom that need to do something about it, but they just don't. So, we need do some chores to get it work.

Do enjoy!

Got it man. Thanks for your patience! I hope my questions help anyone that might be in a similar situation :)

Does it works on other wacom tablet PCs?

When I tried to calibrate my lenove x230t tablet, I noticed the calibrate points are about the screen resolution.

But the screen of my tablet is not a FullHD one, it's a 1366*768 WXGA screen.

What should I do so that I can make my x230t work with 273 calibrate points?
[Microsoft Surface] petersteier:
For a different screen resolution, just "scale" the numbers. I.e.: x*1366/1920, y*768/1080
[Microsoft Surface] ghostm42:
I just followed your directions on a Lenovo Thinkpad Yoga, which seems to behave the same way. But I noticed something odd.

With the Wacom drivers installed, I deleted the registry settings and ran the command line. After completing the calibration, the pen was very accurate within Windows (ie, pointing to desktop items, etc.). When I opened Photoshop CS6, the calibration was off. I'm not entirely sure why this is. Perhaps Photoshop utilizes Wacom calibration while Windows uses the command line calibration.

Then, I ran the 4 point Wacom calibration as you indicated. This wiped out the benefits of the command line calibration in Windows, but the calibration with Photoshop was much improved.

This seems to confirm that Photoshop is using Wacom calibration while Windows uses its own calibration. Or perhaps Photoshop is using pen calibration, but we had configured the touch calibration?
[Microsoft Surface] VictorFrost:
If it's possible to back up the registry files for the calibration settings then is it possible to install someone elses calibration settings? I understand that there would be some issues with how the pen is held but currently I am at a loss.

I managed to get the original surface stylus to work almost perfectly without wacom drivers, but then I decided to purchase the carbon and install the wacom drivers as everything suggested the stylus was more accurate than the stock one.

About 23 calibration attempts and a reinstall of windows (somehow the calibration got corrupted and I could only click on a quarter of the screen) I am still stuck with the cursor wobbling either behind the stylus, above or below the stylus, or both. When calibrating should I actually click on the crosshair point? Because I seem to be getting closer to the correct result when I am clicking below and right of it. Or should I consider just uninstalling the wacom drivers and testing the calibration with the stock driver?

Also I am not talking about the corners but in general the cursor wobbles even just an inch from the center of the screen.

Thinkpad Tablet 2

In case anyone needed to do this on a 1366x768 screen, here is the command with points scaled 1366/1920 in the x-direction and 768/1080 in the y-direction. I did it on a Thinkpad Tablet 2 with much sucess. The points you have to click look a little wonky, but I'm not sure if that's from the difference in aspect ratio or if that was the original layout. Otherwise, it worked perfectly for accuracy. Still need to figure out how to adjust the pressure sensitivity since I had to uninstall the Wacom drivers to make it work.

tabcal devicekind=pen lincal novalidate XGridPts=7,43,78,114,185,256,327,398,470,576,683,790,896,968,1039,1110,1181,1252,1288,1323,1359 YGridPts=7,43,78,114,178,284,384,484,590,654,690,725,761
[Microsoft Surface] ashcanpete:
I spent a long time getting this to work perfectly on my Surface Pro 2, here's what I did. Note that this setup doesn't include installing the Wacom drivers at the end, because I don't really use Photoshop, but if you need that you can try adding the registry edit steps to this procedure (see earlier post by xiaohang.07).

The first step is to clear out old calibrations by installing/uninstalling Wacom drivers. (If you already have Wacom drivers, skip to step 3)

(If you never messed with tabcal commands before, you should be able to just reset the pen calibrations in the control panel and skip this part)

Install Wacom drivers (ISD_DualTouch_720-4.exe)

Reboot

Uninstall Wacom drivers through control panel-->uninstall programs

Reboot

Note - You must choose which screen orientation you will use to calibrate the pen. Once you calibrate, rotating the screen will not change that calibration. So unless you always hold your pen completely vertically when you write, you will only be able to achieve perfect accuracy with one orientation.

However, windows seems to store 2 separate calibrations for the Surface, one with the keyboard attached, and one without it attached. So you can choose one orientation with keyboard, and one orientation without the keyboard (attached upside down is the same as detached). You can decide what will work best for you, here’s how to setup the calibration I prefer:

Keyboard attached - landscape

Keyboard removed (or upside down) - portrait

Make sure keyboard is attached and surface is in landscape orientation

Run command prompt as administrator

Enter following command:

tabcal devicekind=pen lincal novalidate XGridPts=10,60,110,160,260,360,460,560,660,810,960,1110,1260,1360,1460,1560,1660,1760,1810,1860,1910 YGridPts=10,60,110,160,250,400,540,680,830,920,970,1020,1070

Do landscape calibration with keyboard attached (folded back on flat surface is easier) (hold pen as you would when writing)

Remove keyboard, rotate to portrait

Enter following command:

tabcal devicekind=pen lincal novalidate XGridPts=10,60,110,160,250,400,540,680,830,920,970,1020,1070 YGridPts=10,60,110,160,260,360,460,560,660,810,960,1110,1260,1360,1460,1560,1660,1760,1810,1860,1910

Do portrait calibration without keyboard (again, on flat surface is best, hold pen naturally)

Reboot

Note - feel free to add as many grid points as you like, I chose to use 100 points, its quite accurate and not too tedious.

Took me a lot of fiddling around to get this all worked out, so I hope this helps you skip all that frustration!
[Microsoft Surface] FenrirW0lf:
Good stuff here. I have great results in landscape mode with the keyboard attached following these steps. But I've run into an issue with portrait mode where my pen cursor flies all over the place. Might have to do with the Wacom drivers being installed but I'm not sure yet. Gonna have to try testing for that.
[Microsoft Surface] derausgewanderte:
Just did this on my SPro v1 and it worked great. got very nice tracking even in the corners. Works both in landscape and portrait. I did not install the wacom drivers after this.

thanks again.
[Microsoft Surface] drsomchai:
same as mine on SP1

so now I use default setting.
[Microsoft Surface] FenrirW0lf:
I actually fixed the issue by just using the first set of calibration points for both landscape/keyboard on and portrait/keyboard off.
[Microsoft Surface] Gregz78:
If you use the wacom drivers only for pen-pressure in Photoshop CC, then you can go with this tutorial that enables pen pressure without Wacom drivers (CC version 14.2 needed):

http://surfaceproartist.com/blog/2014/2/23/photoshop-142-pen-pressure-without-wintab-drivers

This way, you can do the 273 points calibration easily.

I'll try that and give feedback later.

Edit: It works flawlessly.

calibration question

Hey,

i'm new in this Forum. I have a new ThinkPad 10 and calibrated it with this command "tabcal devicekind=pen lincal novalidate XGridPts=10,60,110,160,260,360,460,560,660,810,960,1110,1260,1360,1460,1560,1660,1760,1810,1860,1910 YGridPts=10,60,110,160,250,400,540,680,830,920,970,1020,1070"

But the screen resolution is 1920x1200. So the bottom line is still uncalibrated and unprecise. I tried to add the YGridpts "1120" and "1170" but then an error message appears that the digitizer could not find. can someone help me please?

Greetings from Germany,

Devo
[Microsoft Surface] Bukacki:
help

I Need help i have an xps18 and a dell active stylus.

when trying the code provided it just says digitizer not found.

i can't get it to recalibrate for pen input. the stylus screen reacts but its shows it being touched everwhere but any area near the stylus tip.

so if its reacting im guessing it might be possible to get it to work.

or does someone have a driver or link to fix this?

it seems it would work if i had some way to calibrate or edit the active stylus it self.

the computer responds differently when the buttons on the stylus are pressed.

is the a way to change how the stylus interacts with the screen?

thanks in advance.
[Microsoft Surface] voluptuary:
I think both of you are having the same issue, or should I say both doing the same thing wrong. The devices you are using I'm guessing dont have a native resolution of 1080p so you have to modify the grid points to something that works for your displays resolution. Just use a little math to divide the vertical and horizontal resolutions for your device up into nice even chunks and replace the values in the command and you should be good to go.
[Microsoft Surface] quoshon:
With the new wacom drivers installed when i follow xiaohang.07's instructions the grid dosent show up the screen just flashes blue then goes to the normal wacom calibration screen.
[Microsoft Surface] leblond:
It's the same with me without the blue flash. The old wacom driver (ISD_DualTouch_711-16.exe) works fine with xiaohang.07's instructions:
[Microsoft Surface] godofwar424:
This is now redundant!

Wacom's most recent FeelIT driver 7.2.0-10 has individual profiles for each orientation AND it also allows the option for proper edge calibration all built into their package.

I have tested it out and the orientation thing works flawlessly as does the edge calibration! Much better then messing with a command line as well as providing all the pressure sensitivity for Photoshop etc.

I am using a Thinkpad Yoga in case anybody was wondering.
[Microsoft Surface] petersteier:
Sorry, I disagree. For me, the result with the "many point" calibration (I do 130, see above) is much better than with the FeelIT ~25 point procedure. However, installing the wycom driver destroyes the calibration data, and I had to do system recovery to get rid of the driver and redo the 130 point calibration.

[Microsoft Surface] xkawer:
Calibration stops in the middle

I tried the method of the first post, however after a quarter or so of the points I can't click with the pen anymore, it does the small ripple animation, but the crosshair does not go to the next point. I can still right click with the pen and go back to the last point, but not to the next point. I do not have the Wacom feel driver installed. Any clues?
[Microsoft Surface] ZoneBlaze:
I've got a surface pro 1 and installed the latest driver but the edge calibration doesn't appear properly. Only the first point appears and it's on the upper left corner of the screen(Literally in the corner). After tapping that, the second one doesn't appear... I've tried the edge calibration with the dpi scaling disabled and enabled, still the same.

Please advise

Hi Guys,

I am trying to improve the calibration on my fujitsu t900 laptop (tablet pc) which has a 1280x800 resolution in the landscape orientation.

However I am struggling to use the method described by the learned gentleman in the original post.

I have reset the calibration data, and used the following codes in command prompt;

Tabcal devicekind=pen lincal novalidate XGridPts=5,15,30,50,70,90,120,259,513,767,1021,1180,1210,1240,1280 YGridPts=5,15,50,100,163,223,321,479,640,740,780,800

And

tabcal lincal novalidate XGridPts=7,17,60,165,365,683,1001,1201,1280 YGridPts=7,13,39,105,225,400,575,695,755,800

However both times I get the message; ‘invalid grid data’.

If someone could be so good as to explain to me what I am doing wrong, and how I could correct my error I would be most grateful.

Thank you.

HP SPLIT X2 13.3" (Tablet PC) Windows 8 x64

I just had the touch screen digitizer and LCD replaced and since then, the calibration has never been right. When i calibrate with some certain values, some points work and others don't. when i calibrate again with another another set of values, those points working before stop. The issue is mainly at the bottom. when i tap and hold any part of the bottom screen, the feedback is seen either some inches to the top or some to the right.

1. Could this be that the touch screen digitizer is bad?

2. does it have anything to do with the graphics driver since the one installed was for the previous touch screen digitizer and LCD?

3. the last calibration i used was "tabcal devicekind=touch lincal novalidate XGridPts=7,43,78,114,185,256,327,398,470,576,683,790,896,968,1039,1110,1181,1252,1288,1323,1359 YGridPts=7,43,78,114,178,284,384,484,590,654,690,725,761" since my screen resolution is 1366x768 (i changed the value devicekind to TOUCH since it doesn't use pen)

I would have returned but am continents far away from the seller

[Microsoft Surface] petersteier:
I have done some research on my surface pro 3, maybe helpful. Please comment if something is wrong, and check information on other devices.

Some background: There are two problems with digitizers, and thus two kinds of calibration in Windows. The first one is non-linearity: the location of the pen is not detected exactly, but there is a position dependent offset. This deviations were awful with some devices I had in the past, the NTRIG in my Surface Pro 3 is in fact much better: on the left side of the screen, the deviation is about 0.3 mm (~1/100") horizontally, to the right no deviation is detectable. Some people may call this "calibration not recommended", but in High School in technical drawing a precision of 0.1 mm was expected (with a sharp pencil, I'm 50 years old).

Secondly, the digitizer does not detect the contact point of the pen with the glass, but some point 1 to 2 mm (1/16") from the tip. Thus, if you tilt the pen, the detected spot will move. I will call this effect "parallax".

These two effects are completely independent and have no connection with each other.

The Non-Linearity is corrected by Windows by the LinearityData (stored in the Windows Registry -> Wikipedia). To change it, you first have to clear the calibration data in the Tablet PC dialogue, and then click "Calibrate". You get a 16 point calibration grid; as this is the Linearity correction, you should hit these points with the Pen held exactly perpenticular to the screen.

If you now hit the "calibrate" button in the TabletPC settings again, you see the 4-point calibration. In fact, this is the parallax correction! Hold the pen at your comfortable writing angle, and hit the four points.

Naturally, the Linearity Correction is independent of screen rotation, thus there is only one data set (in the registry).

There are, however, four different parallax correction data sets; you can produce them all by repeating the 4-point calibration in all four screen rotations. Additionally, there seem to be two data sets for landscape with and without keyboard attached. You now have a perfectly calibrated screen in all screen rotations.

There is useful information on techniques for a "better" non-linearity correction here, but also at http://www.surfaceforums.net/threads/properly-calibrating-the-pen.5157/ However, it does not seem necessary at my Surface Pro 3. One problem with tabcal.exe is that it creates an entry "LinearityData" in the registry, instead of "UserLinearityData". This overrules "LinearityData", but cannot be deleted with the TabletPC dialogue. One has to use regedit (-> Google) to get rid of it.

I would like to be able to perform the 4-point parallax calibration without the linearity calibration, however, you have to go through linearity to be able to do the parallax. You should be very precise when doing the linearity calibration, or you will actually degrade the linearity: drink no coffee before, and hold year breath.

BTW, I could not locate where Windows 10 stores the parallax correction for NTRIG (Wacom tablets store it at C:\Users[your user name]\AppData\Roaming\WTablet\ISD_Tablet.dat).

Background, on T-mobile rooted and running PACMan ROM 20.0.1

1. I can't get my Wifi tether to work for free? Everyone says after rooting it should tether for free and not get the message, doesn't seem to work? Have the work-around by using the "Agent Switcher" on Google Chrome, but would still like to know why it won't work.

2. My phone's been stuck on 3G for a very long time. Possibly after I rooted and flashed the ROM, don't remember exactly but I haven't seen the H or 4G in over a month.

3. Super crappy battery life. If I leave my tether on for an hour. I lose 20%+ of my battery(tested it). Everyone's battery seems to get better after the rooting and such.

2. Flash latest modem, it will let h+ icon happen when cell data is requested. Been covered soooo many times.

3. Depends on what you do, how you use you're phone... my battery is always better on touchwiz ROMs but very good still on aosp style ROMs. Play with kernels and mess with settings to find what your phone likes. Not what mine likes what yours likes.
