If the PSM timing of a display is a multiple of the PSM timing of an ambient light, such as a 120Hz monitor and a 60Hz room light, then you can get viciously headache-inducing flickering on the display.
The frequency is about 1KHz. And it isn't really an LED issue. It is any flickering at the wrong speed. Flourescent tubes were know for the issue a long time before LEDs. As were CRTs. And the combination was bad. At 1KHz, the Forma should be beyond anything you an see and is unlikely to interact with anything in a bad way.
