    I did a bit of research into MHL (Mobile High-Definition Link) and discovered it has the following feature according to Wikipedia:

    HDMI-CEC control of remote devices.

    http://en.wikipedia.org/wiki/Mobile_High-Definition_Link

    Additionally, the MHL specification states:

    Fully interoperable remote control features to navigate and control mobile device media playback, apps and other extensive features

    Does this mean that if I connect my smartphone to a touchscreen monitor using an MHL to HDMI adapter - I can control the phone with a secondary touchscreen?

    I also had this problem & seem to have resolved it finally.

    Control Panel\Appearance and Personalization\Display\Screen Resolution

    Advanced Settings > Properties (ATI Radeon HD 3200) > Driver - Just clicked Roll Back Driver.

    Seems to work more or less the same.
