Login Screen Scaling

[sevendave]

Hi, got a hack up and running with more or less everything working, there's just one niggle - I have a 4k monitor and am using scaling so it looks like 2560x1440: after loading up, the login screen is at the full 4k res with no scaling, it's only when I log in that it changes the scaling to 2560x1440. I've tried setting the resolution as root user as per this thread -
http://www.tonymacx86.com/el-capitan-laptop-support/174675-login-screen-resolution.html
but that doesn't seem to be working for me.
I'm on Yosemite with Clover bootloader, 2 x GTX 980s (if that makes a difference), using the Nvidia web drivers. Got CSM disabled so clover is running at 4k too.
Anybody got any ideas? It's not a major issue, only way it affects me is that the Dashboard widgets are loaded at 1:1 scaling and then scaled up so are pixelated.
Thanks!

Did you figure this out?

Try running the command below after setting the resolution in "System Preferences > Displays > Scaled" on the root account.

sudo rm /Library/Preferences/com.apple.windowserver.plist
