Does a second screen cost performance?

I want to get a second screen and now wonder if that has any effects. So if. For example, I play ps4 on one screen and watch YouTube videos on my PC on the other screen. And: what criteria do you have to meet for a second screen? So do you need some kind of adapter or something? And: if I play on the PC, for example, and watch a video on the other monitor, for example, via the Pc, is that more power that is required or is it about the same as when I opened a tab in the browser? Thanks!

ps: unfortunately I have a bad PC that's why I ask

No, only if you connect 2 screens to the PC and then that is very little if you only watch videos on the side.

Of course he does! But depending on what you're doing and what graphics card you have, you won't notice it.

Of course, this consumes computing power… Even if very little! See my answer.

Aja and only watch videos. Show me how a 4K video at 60 FPS has very low power consumption on my 2nd monitor

That is what I have written.

You denied it DIRECTLY in the 1st word!

Yes, it might be 5-10% decoding. Isn't really much now.

And what's next?!

That no was true for the PS4 example.

Aloha!

The monitor itself won't draw much power. More like the video you're watching. You have to know for yourself whether you need an adapter or not. Does your graphics card still have a free connection?

It's like saying: "No, this car doesn't have that much power, only 400 hp which pushes you properly into the seat"

Naia, let's not argue!

Ahoy, just read half the question xS

Bad example. Here's a better one:

"No, electricity is not dangerous for you. Only if you plug it into the socket with a fork and then you really have to go in with what happens"

No question, exception follows. It's actually very easy.

Got it. Just blame me
