pressure sensitivity uneven on different areas of the screen

2013-09-16, 7:45 AM

Just upgraded my x230t to win8. After much trial and error I finally got the pen to have very little pressure sensitivity by increasing the hardness of the pen tip to full in the pen settings (control panel). But I am not sure if this is pressure sensitivity. The problem now is that I get thin light lines in the middle of the screen but hard dark lines after the middle region of the screen when drawing with the same pressure. And its the same regions even if i move the canvas. I have attatched a screen shot too. Could it be my screen or my digitizer? I am confused...... please help. 

The lines on the attached pic is drawn with equal pressure.Capture12.JPG

It was the digitizer pen. I replaced it with a new pen and its good now. Thankyou for your help...

The conditions of the experiment are not evidence. It is impossible to draw freehand lines with equal pressure on the entire surface of the canvas. You may have to retry using a ruler, in tablet mode, the side of your hand (don’t forget to put on a thin glove) sliding onto the screen.

 

Example with my X220t in ArtRage Studio. I used the ruler stencil. (Highly compressed jpeg image):

Here is a better example, under the same conditions:

I understand that but I was just trying to show that the lines on the middle are lighter no matter how hard I press and the lines on the outer edge are darker and thicker no matter how light I press. Btw I get the same result with or without a ruler.

So it sounds like a problem with your screen.

 

EDIT: try to unset the calibration.
