I wanted to update my TomTom, so I downloaded their My Drive Connect program.
Installed it, started it, and plugged my TomTom into a usb port.
I noticed in the task bar that a driver was being installed for it.
Then the whole system became sluggish and unresponsive.
I finally got the program to shut down, unplugged the TomTom and restarted the pc.
Now the only screen resolution I can use it 640x480. The drop down is greyed out.
I unplugged the vga cable and found a hdmi cable I had.
Now I have my screen back to normal.
I tried to update the graphics card driver, but it says it is up to date.
So what went wrong and how do I fix it?
It actually looked better with the vga cable.
