Raspberry pi 4 Black screen

I have a raspberry pi 4b when I turn on the pi the green led blinks 11 times and then stays on, during boot nothing appears on the screen and after that, same thing, and if I try to access it via ssh it fails, sorry for my terrible English

How did you install the OS? Have you tried the second HDMI connection? What error message do you get with SSH?

i installed the os with rpi-imager

Have you tried to use the hostname when ssh ? Raspberry Pi OS is using LLMNR/mDNS, so it multicast its hostname to all devices on the network your on.

You state 11 fast blink and I cant't find that but 10 blinks is that the Raspberry Pi 4 is in HALT state. https://support.pishop.ca/article/33-raspberry-pi-act-led-error-patterns
