TFT Monitor Screen Positioning

Hi

 

I have recently updated the drivers for my tft monitor (cant find the model number because its in Chinese) through Microsoft Updates.

 

When restarting my computer the resolution had changed to 800x640.  When I attempted to change it to the higher setting of 1024x768 the screen resolution changes as expected but the screen is no longer centred it is off to the left.  I cannot move it back into the centre using the monitor options.

 

Is there something i'm missing or forgot to do?

 

Please help !
