He's not wrong.

If you have your back to them, they don't emit light either!

Edit: Well, reflections, for you with the FANCY GPUs...

Exactly what I thought while I was commenting that. The reflections are what made me rewrite it

OLED displays (which are definitely a thing for desktop computers and TVs)

Probably not for most people, due to cost. More realistic for portable devices where battery saving is a thing, as it doesn't seem like there's much mainstream push for OLED (or similar equivalent) monitors that aren't top-end (on newegg, I could only find 240Hz options).

That and often search results are for other panel technologies (IPS/TN/VA). Lower spec stuff seems to exist but you really gotta scrape the bottom of the barrel (portable monitors) to find some niche product.

But what about candles?

Which is really unexpected if you're looking at an oil lamp.

Actually, the pixels go completely black and do not consume any electricity at all in that state.

You might be thinking of early OLEDs, which had to stay on at all times to prevent blur/smearing. But panel manufacturers solved that problem a few years ago. Don't remember exactly when the change happened, but I remember first seeing true black OLEDs sometime around 2017/2018.

Every electronic device in the game uses real electricity. Even if it's not on.

If the game is demanding enough they also consume the same amount of electricity, maybe even more.

When a lamp turns off it doesn't become a black hole. Previous commenter was correct, though I appreciate your info about OLED

Change electricity to energy and we’re good again

That depends on how the game does reflections. In some games they have a mirrored room with an identical but different light for the reflection.

So do lamps irl.

I'd argue that's not true if the lighting is baked into the map.

[email protected]

Does it matter?
The screen still has to display it.

[email protected]

So does every other pixel in the game

[email protected]

The GPU renders the map no matter if there is lighting baked in our not. It's exactly the same operation. And depending on your display tech, brighter pixels might actually use slightly less energy.

Also we don't launch towards the sun, we deorbit by burning in the opposite direction of where the earth is moving towards.

But they still use energy.

Nope. Only the screens do. Technically you could play a video game without a screen.
