Problems with Serial-Port / Screen after turning on VTX in Bios

[ Edited ]



I have a HP Compaq Elite 8300 CMT running Windows 8.1.

As I want to develop Mobile-App's (including Windows-Phone) I need the Windows-Phone-Emulator from Visual Studio 2013 (Update 2).

If i have started the Emulator the first time, there was an error-message displayed (from VS), that i have to change my Bios-Settings.

=> I then have changed the Bios-Settiing (set Virtualisierungstechnonolgie (vtx) to enabled 

After that, the Windows-Phone-Emulator works now


but I have the following negative Seideffects:

- If the screensaver starts up, i can't reach the Windows-Login-Screen my move the mouse or make a keystroke

  => Nothing happens then, I have to change the sources to my (Dell) Screen (on the screen) and move the mouse to

       activate the Windows-Login-Screen

- We develop Software with CTI (ComputerTelefon Integration)

  => The Phone is connected via serial cable to the serial-port of the PC

  => This also don't work anymore (and this IS really important for me)


What can I do to solve this problems?


Thanks for a fast feedback.



- The problem with the serial-port is solved / does not exist:

  - The Tapi-Provider in the appication was - for whatever reason - reseted

  => I have reasigned the correct provieder - now ith works again

- The problem with the screensaver remains
