I'm looking to get a 2019 Samsung TV, which supports serial. Is it actually possible to query the Samsung to get status information (for example, power status, source input being used, etc.)?
Does it support ExLink or MDC Protocol? Tvís that support ExLink will have the port on the back of the tv labeled as ExLink
TVís that support MDC Protocol (digital signage displays) will have an RS232C In Port. Video wall signage displays typically have both an In and an Out port.
My ME Series displays have in/out port so you can daisy chain and control them all via RS232.
