Hi, I have a Acer Predator X27U X1bmiiphx 27" WQHD (2560 x 1440) Widescreen OLED Gaming Monitor. If I boot with HDMI + DP plugged in, "no signal".

If I boot with just HDMI, it will boot. After I login (linux), I can plug in DP and swap to DP.

Any idea how to fix this?

Also, how do I turn off the "monitor will power down in 6 minutes and blink" message that pops up
