Dual Monitor Setup

Hi Guys,
 
Just had my PC installed with Windows 10. Everything works fine except that my dual screen monitors are mirroring each other which I don't want. The system also only detects one screen although there are two. The graphics card installed is a ATI Radeon HD 3450. Checked the Device Manager and apparently the display adapter registers it as ATI Radeon HD 3450. However the monitors are listed as Generic PnP Monitors. What does this mean? I also checked for updated drivers for the display adapter and it only accommodates OS's up till Windows 8 (64 bit.) Could this be the reason for the detection of one monitor instead of two? I would be very grateful for a solution.
 
Thanks in advance.

Thanks for your reply. Unfortunately this option does not exist as it only recognises both screens as one monitor. My only conclusion is that becuase the driver support is only limited to Windows 8, this problem occurs.

There are several reasons which can cause this error in your computer. One of these is a corrupted or missing system file. You may run the System File Checkerto identify and troubleshoot this error. 

 

You can also follow the steps through Fix Windows Update errors by using the DISM or System Update Readiness toolto check for any update errors. 

 
Note: Please perform the Clean boot on your PC. 

 

Clean Boot temporarily disables all third party applications as well as all Microsoft non-essential services so only basic drivers will run. This will help us find any third-party software which can be the cause of this issue. 

 
Here are the steps: 

 
 

  1. From Start, search for msconfig 

  2. Select System Configurationfrom the search results. 

  3. On the Services tab of the System Configuration dialog box, tap or click to select the Hide all Microsoft servicescheck box, and then tap or click Disable all. 

  4. On the Startup tab of the System Configuration dialog box, tap or click Open Task Manager. 

  5. On the Startup tab in Task Manager, for each startup item, select the item and then click Disable. 

  6. Close Task Manager. 

  7. On the Startup tab of the System Configuration dialog box, tap or click OK, and then restart the computer. 

 

Regards.
