I'm experimenting with a 2x16 LCD and, instead of using a 10K pot to adjust the contrast, I use a 10K resistor with a diode to get the Vo voltage. The contrast seems fine with the model I got.
Is there any disavantage to this method? The LCD is intended to be used at normal room temperature.

It won't work in the cold, may not work with a replacement LCD, and may have minor changes as the display ages.
Hmmm! Ok, a pot is a better choice then. Just trying to be cheap ;)
