Hello,
Thx you Ralf for your help but…
I did some tests. But nothing change :-(
– DK2 as the secondary screen: ok
– Show only on Rift DK2: ok
– Skyrim install without any mods: ok
– No antivirus: ok
– MSI Afterburner, like Splashtop, video recording and many chat programs like (X-Fire, Skype etc.): ok
I have Geforce Experience drivers but I disable Nvidia tools.
It changes nothing. The display will always start in “normal”.
Another idea?
Best regards,
Numael
