Summary: Viewsonic customer service is nonexistent and product support worse than poor. Products are poorly made and will not last. Call technical support 1800-688-6688 and see how long you have to wait for a service rep. Online you get someone to respond who barely speaks English.
Summary: I bought this from Costco, instead of Amazon because they had a price that was "too good to be true". And it was! Unfortunately this screen was a non-starter for anyone who does digital imaging or critical viewing of anything.
