Hyper V VM with 16:9 resolution

I have a windows XP VM installed in Hyper V.  I would like to record a session within the VM, but I couldn't set the screen resolution to 1080x720. 

I then enabled remote desktop in the VM.

Then everything works perfectly. 

I have to run the screen recorder from the host machine. When I ran it within the VM, the mouse doesn't work well.

I am trying to attach my android phone to the VM, but failed. 

I also tried the remote desktop Pnp device, didn't help.

Comparing to VMWare Workstation, Hyper-V gave me a lot of troubles.  I would rather leave it for now, I am going back to virtual box.
