Any help please

The Kali team is very small, and does not have access to a large set of hardware. You will likely need to troubleshoot this and provide logs. I would recommend enabling ssh into the system, and then ssh in to it while it's showing the issues, and look at the dmesg output and the different log files in /var/log; Ones that may have some importance would be any in /var/log/lightdm, Xorg.X.log (where X is a number), and the kernel/syslog files.

Based on reading the info you have provided, it appears to be using nouveau for the gpu driver, have you tried the proprietary Nvidia cards already (documentation should be available at https://kali.org/docs )

Thanks for your response
I found this article https://www.kali.org/docs/general-use/install-nvidia-drivers-on-kali-linux/
I have already correct the blinking problem, now i have to troubleshoot the resolution problem
Max resolution is 1280x768 it's very poor, it's my next step :)
Thanks for answering me :)

I'm closing this as it seems like the issue was solved with the nvidia drivers
