Building a Magic Mirror with touchscreen monitor

[teresaooliver]

Hi, I am planning to build 50 units of a Touch Screen Magic Mirror for an e-commerce project. I am using a capacitive touch screen for the quick response and I have confirmed this with the manufacturer. He said that this will work perfectly. I am using a 21.5 Inch Touch Screen Monitor for this project with 350 Nits brightness.

The supplier quoted me $250 for this 21.5" touch screen monitor but he also said that he will negotiate the price. Now, I am a little bit confused about the technical specs. Can someone check the specs and provide me with your feedback? I will appreciate your comments.
