@chrissttian Hi.

Touch screen kit: http://www.aliexpress.com/item/21-5Inch-Resistive-Touch-Screen-Panel-490x285mm-4Wire-USB-kit-for-21-5-monitor/32429848194.html

Mirror film: https://www.amazon.com/One-Mirror-Silver-Silver-CHROME-Film/dp/B00NBXFA7G/ref=sr_1_3?ie=UTF8&qid=1469284739&sr=8-3&keywords=2+way+mirror+film
(not exactly what I bought but something similar. This should work though I think).

@chrissttian The film is applied on the touch screen panel kit, not on the monitor itself. The touch works behind the mirror film since it is a resistive touch screen and works via pressure.

I used a credit card to squeegee the film on the panel, but I highly highly recommend using an actual “smoothie squeegee” as seen in the below video at 5:12. The credit card works okay, but it is way more prone to scratching the film (which my mirror actually does have some small scratches on it because of this).

I generally just followed this video for applying the film. Just instead of a window, you’re applying it to the touch screen panel.
