Qemu can't fullscreen on TC8 TC9

[fnq3]

 on TC7, I run the qemu-system-x86_64 with options "--full-screen" , VM can display on the full screen.

But  on TC8, although with this parameter"--full-screen", but the output is still a window,  not full screen.
on tc9 too .
 
Does anyone have any solutions?
Thank you

  I'm sorry, my English is very poor.

Hi,

Please try setting the vga=7xx bootcode, as explained in http://distro.ibiblio.org/tinycorelinux/faq.html#bootcodes and check.

I'm sorry. I didn't say clear
In the physical machine is running is TC8
Execute the command "qemu" with "--full-screen"  to start a virtual machine
But qemu is a window, cannot achieve full screen
