As far as the exact model of ELO that we sell, I do not know. I believe it changes depending on what models are available at the time that the order is placed.

If the touchscreen that you select emulates a mouse click when touched, then it will work perfectly with bpa.

Sorry that you have had a tough time with your dell monitors. I've dealt with a lot of those over the years and they were very reliable. It's sad to see that you got a bad batch.
