This issue has been annoying me very much. I search on MSDN, support.microsoft.com, but I keep getting answers such as "my display resolution won't change in settings" type of thing. But mine is different: I have a QHD 2560×1440 display, but the problem is, the resolution only changes after I login. For example:
Press the Power button –> BIOS boots –> Windows Lockscreen on 1920×1080 –> logs on to my user –> resolution changes to 2560×1440.
Why is this so? I want the crisp lock screen quality of QHD but I get 1920×1080 instead. I suspect that there is a user setting that changes the resolution upon login. But I want the global resolution to be 2560×1440, not 1920×1080. Is there a registry value somewhere or can I write a PS script to set the global resolution? Thanks in advance!

The problem was that Parsec was enabled before I logged on. Therefore, thru some oddity, Parsec set my resolution to its default 1920x1080. I deleted Parsec RDP and rebooted. Everything worked again.
