That applies regardless of whether or not the tv is “smart” - my current “smart” Roku TV runs great, and I had an old “dumb” Samsung that took forever to do anything.

Well-written software is what helps here, not smartness or lack thereof.

No, dumbness helps. You want to solve the input delay, you can use an external HDMI switch or get a dumb TV.
