Chosen Solution

I have an asus tp550la transformer notebook that has recently had the digitizer replaced. y axis is fine but the x axis is reversed, when you tap from centre to right, it shows you going left! I have replaced the digitizer twice and completely wiped the hard drive to no avail. thanks for reading

There are 2 versions of the touch screen for this model. I’m willing to bet that you have the wrong one. That’s the only thing that I’m aware of that can cause this.

its ok, I think I have found it http://www.amazon.co.uk/TRANSFORMER-TP55… going to give it a try, fingers crossed! thanks very much for your insight

well the replacement came today, and the same problem STILL persists, could It be a motherboard issue? ive checked drivers, settings etc I cant find any similar issue online, its all tablets and nothing with laptops having this problem

Solution is control panel\ Hardware and Sound\ Tablet PC Settings\ Calibrate\ then follow the prompt. Enjoy.

I am having TP550LA SH51T -CB Its touchscreen is damaged - display is ok, I need to know how to identity PART NUMBER orTouchscreen version. I need to buy from ebay and install rather than to pay 510 CAD to Asus Support. Please help !
