A: NO, OF COURSE IT DOESN'T!!!

A: No reason to use a screen saver except if you have an OLED. How do you know if you have an OLED? You would know! They cost two to three times more than a VA or IPS panel.

A: That's a good idea! If you have a black background, and your taskbar is set to auto-hide, it's the same. However, if you have several windows open, arranged properly, it's easier to just click "Go Dark!". Also, pop-ups and notifications may appear later that are covered by the screen saver.

A: You can, nothing wrong with that, just a few minor differences:

• Most importantly, 12G-Black does not respond to mouse moves! A Windows screen saver turns off when you bump against your desk and the mouse moves ever so slightly. And: on a second monitor you can still work and click!
• Speaking of two monitors, 12g Black can be set to cover only one screen (your OLED), while your second monitor is still visible and accessible. No need to use a screen saver on a non-OLED monitor, it does not save any energy since the backlight is always on. OLEDs, on the other hand, turn off each pixel and thus need less energy for a dark or black screen.
• Btw, you can easily reverse monitors, for example while watching a video on your main (OLED) monitor you can darken the other monitor(s).
• 12G-Black does not flicker! All Windows screen savers show a white flash when turning on and off. Not a big deal but once you notice it you can't un-see it.

A: No matter if you have a notebook with an OLED screen, a QD-OLED or W-OLED monitor, or an OLED TV, you've spent a ton-load of money and want to protect your screen from possible burn-in. Here are five easy steps you should follow:

1. Keep the window backgrounds as dark as possible: right-click on your desktop and select 'Personalize', click 'Colors', and at 'Choose your mode' select 'Dark'. Now the background of most apps is dark. This requires less energy. And your OLED won't get as hot.
2. Remove any wallpaper and colors: right-click on your desktop and select 'Personalize', click 'Background', select 'Solid Color' and choose black (or the darkest color you can stomach...)
3. Make the taskbar disappear automatically: right-click on the taskbar an select 'Taskbar settings', at the bottom click 'Taskbar behaviors', and check 'Automatically hide the taskbar'. This is the most important one since bright colorful icons on your taskbar stay at the same position forever.
4. Set up 12G-Black to cover all running programs: in settings check 'Go black after' and choose a time of 3 to 5 minutes, and in 'Select screens to go black' make sure your OLED is selected. Non-OLED monitors and TVs don't save energy when they show black - the background light is still on full power. You can leave them on so you can always see apps on that other screen, like media controls or a clock (which, btw, is the main reason for a second monitor and the default scenario for all 12Gadgets.)
5. Don't worry! Our five year old LG C8 - after more than 20,000 operating hours as main desktop monitor (roughly 10 hours a day) - has no visible artifacts whatsoever. No reason to lose any sleep over, and after five years you probably want a new (bigger!) screen anyway.
