Question Monitor shows black screen if powered on after the CPU?

[Screx]

So this is happening since day 1 when I plugged in my new RX 580, the monitor works fine if I turn it on before I power on the CPU. But when I power on the CPU first and then the monitor, it just remains blank with no output? Why is this happening? This did not happen when I used the onboard graphics

Could be hdmi handshake between gpu and monitor. I looked if there were any firmware updates available, doesn't seem so.

Does onboard graphics do the same? To see if it's monitor or gpu?

I need to do the same with my monitor but in reverse, pc on first before monitor. 1080Ti, xb270Hu - Displayport cable.

It doesn't do this if I connect it to onboard graphics & the monitor only has HDMI ports and no DVI/do either, I tried using all the ports on both GPU and the monitor, it still does the same thing.

Not much can do really, during post its all basic plug and play, no drivers are initiated yet.

Maybe look through the monitor's onscreen menu for power saving features or similar to fiddle with.

Just gonna have to get used to it like me haha

Yeah, most likely a "feature" of the inexpensive monitor. Have you ever tried it with other gfx cards? (not the iGPU)

Sadly I don't have any other GPUs so can't test it, but since it's not that big of an issue I can just overlook it I guess.
