Did you mean B326HUL for the model number? You might have a bad monitor, but probably not.
I would first confirm that that yuou get get an image on the Acer hdmi input using a computer. One you have confirmed this, you can move on to troubleshooting why the Acer hdmi input is not working with the BD player.
There may be a setting on BD player that needs to be changed. What is the model of it?
