Device for Netflix on the TV?

I want to watch Netflix on my television but only have one "screen" with multiple ports. I thought about getting a smart TV, but I ONLY need Netflix. So no YouTube, Prime or something. I have a Netflix account, but so far I only look at my cell phone and laptop. Is there also an option that is as inexpensive as possible?

Connect laptop to TV.

Just need a cable.

Get an Amazon FireTV Stick "lite" today or tomorrow (Black Friday) for around 20 EUR. You can use it for free without Prime and use Netflix over it.

All you need is an HDMI input on your monitor.

If you have an iPhone, you should get an Apple TV. Is the best system in the long term.
