Do they use more than dark places in video games? Like if you are in dark room in the game, and you turn on a lamp in the game, are you using more electricity?
My guess is no but I am not a programmer or electrician nor a physicist.
if you have an oled display, then if a video game is brighter it costs more energy because the LEDs turn on more.
if have an lcd display, there's a backlight that always has the same brightness and crystals blocking the light, which makes the image. meaning a brighter scene doesn't take more power, since the backlight doesn't use more energy.
On an LCD display, the backlight is always on but the crystals need power to align and let the backlight through.
A full white screen would in theory use more electricity than a full black screen. How much more, I don't actually know but I would like to know more info in it.
If the light is not dynamic at all, no. If it has stuff like dynamic shadows it will require more processing power to render frames than if the light was off, which probably makes the CPU/GPU draw slightly more power
I'd guess if you have an OLED panel it would because black pixels are 'off' it would consume somewhat of more electricity but I do not know
