You can get excellent "dumb" (i.e. do what I say) monitors, but for a lot more. Like if you want a 55" 4K gaming monitor, you're looking at paying maybe 3-4x what you pay for a smart TV.

Why? That data collection subsidizes your low cost. That's how they offer an excellent 55" 4K tv at a discounted cost of around $1000-1200.
