If OLED Displays have near instant response times, then why aren’t all OLEDs high refresh?

a lack of processing power. OEMs tend to focus on post-processing of image quality and various audio tricks rather than the fastest refresh rate- doing so generally makes for a better TV experience for most people

…personally, I want to watch the news in 240Hz smoothness so I can respond quickly when [anchor A] is actually going ‘back to you, [anchor B]’

Each time that a phone or a computer puts together a frame, it uses a little bit of energy. So increasing frame rate also increases power use a little bit, which is really problematic for mobile devices that need to last through a day with a charge. In addition to that, OLEDs are less efficient than LCD screens, so they already start with a weaker battery life.

The other problem is burn-in. OLED pixels degrade when they light up, which makes them unsuitable for gaming – which is the main market for high refresh rate. OLED TVs and screens for professional video editing meanwhile don’t really benefit from high refresh rate anyway.

High refresh takes power. It takes CPU/GPU power to generate each frame, and it takes display power to display each new frame. It’s a huge power suck. This is why the IIRC the Pixel wouldn’t run at advertised high refresh rate all the time, to save battery life.

Conversely, Apple made the Apple Watch display always on by cutting the refresh down to 1 Hz, one frame per second, when not in active use in order to conserve power.
