Question Monitor Connection over HDMI

Jun 6, 2020
I have a weird problem when I try to connect to the monitor over HDMI.
I have bought ultra-wide monitor ( Asus xg49vq), I made the HDMI connection between monitor and Laptop and projected the laptop screen to it (by Windows P). The computer seems not to recognize the monitor and throws back to Laptop screen again.
But the weird part is when I restart the computer, startup screen appears at the monitor and seconds later it throws back again to Laptop screen.
Also when I open the BIOS screen it appears on the monitor too.

I really dont know If it is because my Laptop doesnt support the ultra-wide monitor. (If so, why it works on start up and on BIOS)
or there is software issue on my Laptop (which is I am not sure, but all the drivers are up-to-date)

Please help! I am lost finding a solution.
