Combination of vibrations and actuators fighting the gyroscopic effect of the off-axis spinning monitor would risk the whole thing violently ripping itself off the desk.
I feel the need to point out that this is why mechanical TV never scaled. From very old memory, if you wanted a 40" screen then the wheel needed to be two stories high.

Would certainly be exciting!
