Ah, I see. I just thought maybe a $350 TV would be more cost effective than 2-3 $250 monitors.
One $15,000 car is also more cost effective than two $10,000 but then the wife won't like walking much. One giant pool may be easier to use than 2 small ones but what if you need one for kids that is not too deep and another regular one?
It's not about cost but about use. It's easier to stick two 20" monitors on a desk than one 32" TV. Plus the image quality on a TV is almost always worse than a monitor.
If you want to use something for games and like a large screen and can sit far away from the screen while using the computer, a larger monitor or even a TV would work. Dual monitors won't work well for games to get a larger screen, a TV would though because there is no bezel to break up the image. But a TV won't work if you want to run a flight sim, because you will have one front view instead of using 3 monitors where you get a front and then side windows on the left/right monitor.
