I use "Display Tech 162B" 2x16 character LCD. Very much standard LCD.

www.displaytech.com.hk/pdf/char/162b%20series-v12.PDF

The good think with this method if succeed is you can remotely monitor any LCD screen of a controller board without interfere with the controller board operation.

It's even better for the controller board that does not have any COM port.
