A bit off topic but I've been thinking there has to be a better way of handling this at the LCD controller level here...
Currently, a 60hz screen isn't perfect and pixel overdrive will be used to reduce motion blur. In effect, there are more 'unique intermediate frames' being displayed as the system tries to approximate the discrete input frames physically. The actual blur on fast-moving content on a modern screen is huge...
Ignoring latency for a moment, if a controller has the previous and next frame plus motion vectors and knowledge of the precise pixel response and decay curves for the monitor... it should be possible to continuously adjust the current/voltages(?) to every pixel to better approximate what a much higher refresh rate low motion blur panel would look like on high fps content. Can't remove blur but can make motion continuous rather than a stair step. A kind of smart motion interpolation + overdrive implementation.
The assumption is the higher fps the more linear the motion is frame to frame. 30 to 60fps interpolation should have more noticeable abnormalities than 120 to 1000hz.
