Trouble regarding dual monitor setup, monitor changes resolution when restarting PC

I'm using a GTX 1080 with an Asus Rog Swift PG279Q (2560x1440) and a BenQ XL2420T (1920x1080) as a secondary display. Both are connected by DP

Every time I restart my computer, my BenQ runs at 720p. The only way I can get it to run 1080p is by replugging it a number of times while it being switched off, then it reverts back to 1080p. Not sure if this is related to my GPU or my monitor(s)...

Edit:
I should add that the max available resolution after a computer restart for the second monitor is 720p, so I can't change it to 1080p in any other way than replugging it x number of times.
Also, it sometimes runs as intended after a restart, but only about 20% of the time...
