Its hard to find a non smart TV these days. Its present even in the cheapest TV at the retail outlet.

How long ago did you buy a dumb panel to even be able to find one? Only dumb panels I’ve found have been PC monitors.

Once you start shopping for LG, Samsung, Sony, TCL, etc everything is a smart TV. And lot of people buy TVs based on specs like HDR quality, latency, and frame output and those TVs usually come as a smart TV whether you want it or not.
