Xbox One to Have 'Light Mode'

During this morning's Xbox Gamescom press conference, it was revealed that Xbox One and Xbox One X will be getting a "light mode."

Exactly what I have wanted from the beginning, can't wait to have a clean white background for the interface!

I can't imagine why anyone would want this.

It's a waste of energy to have your TV lighting up all that empty space for no reason.

Seems like it would be harder on the eyes, too.

Its almost like different people have different tastes in colors

Not correct. LCD TV's don't work that way. It is actually just the opposite. As a general rule darker images (that includes black) actually use more energy on a LCD then lighter images and definitely more than white. On LCD TV's there is backlight that is always on and energy is used to activate the darker pixels to just block out that always on backlight. Doing causes more energy to be used then if we just let the backlight show through or use lower energy to display lighter colors. Without the crystals in the front being turned on the display shows the white of the backlight. The backlight is one reason LCD's actually don't have true black (a complaint often associated with LCD). LCD uses fluorescent backlight behind a matrix of liquid crystal pixels. And similarly LED backlight used white LEDs instead of fluorescent. One difference to this is OLED which has no backlight and each pixel contains LEDs that produce their own light.

So, in essence those of us using the lighter mode are actually being more environmentally conscious than those using darker mode :)

That's absolutely incorrect.

I have my TV plugged into an old Monster power center thing that actually displays the amount of power being drawn at any given time, and I can watch that number increase and decrease based on the amount of light the TV is showing in any given scene.

I've had that thing through 3 TVs, from DLP projection to edge lit Led, to 4k with Full Array Local Dimming, and they all work the same way.

More light = more power.

@UnHoly_One Sorry but, you absolute 100% wrong. That is not how LED displays work. I have actual engineering of the LCD on my side. You can talk all you want but, it is not going magically change how LED displays work. Although, some modern smart TV's can adjust the backlight power a little (lower the color intensity). Even so it is always on and emitting light that the crystals must use more energy to cover up that light create those darker colors.

I will give you a little experiment put your screen saver on your display to black (not turned off in power settings but that "blank" screen saver setting that Windows has - just making it black) and then turn off the lights to your room to make it dark. You will see backlight is still active. What you are actually seeing it is not black it is just turning on all the crystals to emulate black (really just very, very dark grey). So it I is still using the backlight and now using crystals to emulate the black as LCD do. This greater energy use is the same for any color that is not white or uses more of the crystals to create darker colors. Of course, this experiment only works if Windows still is just coloring the screen black and not turning off the display for this screensaver. Now if you turn off the actual power of the display, like some sleep settings do, you are actually turning off the whole display not the crystals themselves. So, it will appear black because you have actually turned off any energy being used by the display.

This is why dead pixels on LCD screens are generally white not black. Because the backlight that is always on is white and the colors are determined by the crystals in front of the backlight and it is those crystals that are damaged..

@UnHoly_One OK, if you are not going to believe me then how about Scientific American. That is fairly reputable journal. https://www.scientificameri...

"... LCD monitors, which have no phosphors and represent the lion's share of every new monitored purchased in the developed world, including those used by laptops. Instead, LCD displays rely on an array of thin-tube fluorescent bulbs that provide a constant source of light to create a white screen. To make it black, LCDs rely on a diffuser to block this light. ... Schindler found that white required 22.6 watts, while black came in a tad higher at 23.2 watts. With a 20-inch (50.8-centimeter) LCD, black required 6 percent more energy than white."

Further more: that very same article quotes Googles own scientists on the matter of Google's almost all white home page.
"Google green energy czar Bill Weihl in August posted a blog disputing the notion of black as the new green. "We applaud the spirit of the idea, but our own analysis as well as that of others shows that making the Google homepage black will not reduce energy consumption," he wrote. "To the contrary, on flat-panel monitors (already estimated to be 75 percent of the market), displaying black may actually increase energy usage."

Ok, so you can give me all the scientific explanations you want, but I'm not going to take that over the example that I see in my living room every single night.

My Power center diplays a number on it that shows how much power is being drawn at any given time. It sits at about 1.1 amps with everything on standby. At max with everything going, I've seen it go up to 5 if I have everything on at once for some reason.

Last night I turned on Roku, and went to the UFC app and paid attention to the display as I was doing this. As the app was loading, the screen is all black except for a white "UFC.TV" in the middle of the screen. My power center showed 2.2a during this part. When it finished loading, and displayed the bright red and white menu that lights up half of the screen, my power draw went up to 3.5a.

Now, I can't begin to explain WHY, or HOW any of this stuff works. All I know is that this thing tells me my TV is sucking more power whenever more of the screen is lit up with bright things than when it is mostly black.

I don't care what the scientific reasoning for any of it is, because what I see in practice is "more light" requires "more power".

Their biggest news from the conference.

gamer780429d ago

Sounds terrible honestly but as long as they keep the darker options that's fine for them to add a mode more options, i just don't need more pixels on my screen fully lit
