I have 1809 running on the second hard drive of the 7i and install the latest studio driver from nvidia to enable 240 fps refresh rate (otherwise the panel is stuck at 64Hz). Thanks for the suggestion!
Laptop is set to discrete GPU, color control dithering disabled.
Difficult to say if this is any better at first glance both holistically and under the scope. I'm not able to get the full raw 240 fps video from the phone camera app just a slowed down version at 30 fps on playback. Still, I was expecting to see more flickering (filmed on the middle part of the lagrom gradient). If someone is watching the video, notice how when I move the camera so that the top left flickering pixels enter the center area, the pixels stops flashing? That is because their is less light captured there and the noise of the phone camera sensor is more visible which itself is a temporally flickering effect.
