    Resolution keeps dropping at login

    Hey folks, weird problem here. I have a dell ultrasharp monitor hooked up via DisplayPort to my desktop, which is running 64 bit Win 10. Graphics card is a Radeon 200 series (specifically an R9 270x) with up-to-date drivers. Pretty much every time I have to login to windows, my resolution drops to the lowest possible and the only way that I have been able to get it to revert is to unplug the displayport cable from the back of the monitor and plug it back in - instantly fixes it. Thinking caps on - how do I fix this?

    I walked through a clean boot, disabled some stuff that just didn't need to be running, but nothing was flagged as set to run in reduced resolution. The extensive registry editing thing other didn't work because some of the flags he was referring to didn't exist for me. Any other thoughts?
