These really can work, too I’ve managed myself to remove what appeared to be the beginnings of a screen burn issue on an OLED TV by running a Pixel Refresh routine. Many OLED TVs also let you run a pixel/panel refresh routine as and when you wish, via dedicated options in the onscreen menus. Here the user will get a message that the refresh system is about to run, and see a white horizontal line on screen when the process is almost finished. The long term LG pixel refresher kicks in every 2000 hours of use, and involves a much longer ‘equalisation’ process that takes up to an hour to complete. You won’t even know that this process is taking place. The short term one sees your LG TV running a pixel refresh that takes around 10 minutes when you turn the TV into standby after running it for more than four uninterrupted hours. On LG OLED TVs the feature has short term and long term elements. This feature essentially attempts to equalise the ‘wear’ on the organic elements in the picture so that no specific parts of the image age faster than the rest. One last rather drastic feature OLED TVs provide to address potential screen burn issues is Panel or Pixel Refreshing.
LG OLED TVs, for instance, have become enormously popular with gamers over the past two to three years, yet complaints about ABL being triggered by static gaming HUD elements are no longer finding their way into our inbox anything like as much as they used to. If you haven’t noticed ABL in action on your OLED TV, try putting a picture with bright, static elements on your screen, such as the opening title screen to the It 4K Blu-ray, and simply pay attention to how the image starts to dim down increasingly heavily after a moment or two.Īgain, fortunately, TV brands have got cuter over the years about how drastic an effect ABL has on the picture (as well as developing the more localised dimming approach mentioned a moment ago).
LG OLED TOTAL POWER ON TIME HOW TO
Unless, anyway, an OLED TV owner happens to know how to access their set’s service menus – and doesn’t mind potentially greatly increasing the chance of screen burn appearing by turning off a feature that manufacturers felt strongly enough about to make it ‘undefeatable’ from the TV’s consumer menus. It doesn’t help that ABL systems are typically baked in to a TV’s picture routines, to ensure a longer panel life span, with no option for the consumer to turn them off. Unfortunately the quite substantial impact this dimming can have in some implementations has become a much bigger source of complaints, especially among gamers, than actual examples of screen burn. Also known as Auto Brightness Limiting (ABL) or Auto Brightness Static Limiting (ABSL), this finds OLED TVs gradually (or in some memorable cases over the years, suddenly) dimming down their entire picture if they sense the presence of a potentially damaging bright, static element.

This is especially true given that the alternative approach may well be full screen dimming. So again, if your TV has this feature, we’d generally be inclined to use it with most types of content. Again, though, in reality, the feature typically makes its adjustments subtly enough not to become very obvious at all. (Note that some other brands can be quite reticent about discussing anti burn-in measures, as it’s a topic they don’t really want to talk about too much)ĭimming down specific areas of the picture sounds, again, like something you might expect to be pretty damaging to your viewing experience. Philips, in particular, actively boasts about the precision of the static image dimming element on its premium OLED TVs. It was LG (OLED’s main innovator over the years) that first introduced this technique, but since then it’s been adopted elsewhere. Here TVs use image analysis to identify static image elements and slightly reduce the brightness and intensity of just that area of the image. There’s usually the option to turn the feature off, but we’d say that in the vast majority of cases this is one of the easiest and least problematic ways of reducing the likelihood of burn in happening.Īnother way of combatting screen burn on a technological level that’s become increasingly popular in recent years is localised picture dimming.
This sounds quite drastic on paper, but in reality the vast majority of people have this feature running on their OLED TVs by default without ever noticing it’s there. This essentially continually circles the image around a pixel or two so that none of the OLED panel pixels are exposed to exactly the same image content. One of the earliest techniques that’s still widely applied on OLED TVs today is pixel orbiting or shifting.
