Question 2nd monitor doesn't turn on at startup

[Nimda672]

I have two monitors connected to my PC. When I turn on my PC, the second monitor doesn't turn on, even though I'm sure that the adapter is working fine. And it doesn't seem to be a software or hardware issue either. However, when I unplug and plug it in the adapter again, the monitor starts to work. What could be the issue here?

One monitor is from xiaomi g24 and another is from samsung( can't remember the model). I used a hdmi cable to plug in the xiaomi monitor and a dp to vga adpater to connect the samsung one (the problem seems to be on the samsung one)
