Ironically my projector bulb just blew, impressively 30 mins ago, off to the service centre tomorrow... Benq W1400, about 5 or 6 years old...A good projector maybe?
When I bought my current TV my intent was to use it as a dumb unit, but it still has SMART features as it's literally impossible to find anything without. That said, you don't need to set up Wi-Fi if you don't want -- I did for firmware updates mainly.
