On the contrary, you have exactly the "stuck in 4:3" problem discussed in the other topic.

Hello mpack,

thanks for your reply, I had drag the border to 1920, and shutdown guest, and restart from VM.
the larger resolution change to 1537x711, it still stuck at 4:3 resolution, could you please describe solution more detail?

Andy, please try an experiment: Put the VM in Full Screen (under the VM window's View menu). See if the VM reports 1920x1080. Then, take the VM out of full-screen and see if 16x9-ish screen sizes are still available.
