Just a quick post to record a solution I just found to a problem I’ve had for ages.
The problem revolves around the AMD crimson drivers when using eyefinity. What happens is the start bar will default to being across all 3 screens on eyefinity setups on boot even when the driver options are set up to force it to the one screen only – usually the centre one. Opening the graphics advanced settings will set it right until the system is rebooted but this is an irritating thing to have to do on every reboot.
I found the solution that worked for me here : https://community.amd.com/thread/192070
Basically what you do is go to the following location
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp
Right click in the window and click new—–>shortcut.
As the location of the item paste in :
For 64 bit
“C:\Program Files (x86)\AMD\CNext\CCCSlim\SLSTaskbar64.exe” -l -e
For 32 bit
“C:\Program Files (x86)\AMD\CNext\CCCSlim\SLSTaskbar.exe” -l -e
Then just click next and finish. If you run the shortcut now you should find your start bar jumps to the correct monitor and will do the same every time you reboot so no need to manually fix it any more!
Hopefully this will help someone else with the same problem!
