[Athen] Windows High Contrast + Magnifier causing screen to flicker?

[Joshua Hori via athen-list]

Sounds like a lower end GPU and/or a low end monitor. If the resolution fix doesn’t sit right with the student, there are external GPU’s (eGPU) that can be added which should fix the screen flickering. I would also be interested in the amount of RAM that’s installed. I like 32G as a minimum (I have 32G RAM on my Macbook, 64G of RAM on my PC).

I always use Displayport for connecting laptops to monitors, which has a screen refresh of 120Hz, while HDMI is limited to 60Hz.

As an alternative, we have a student using Apple Vision Pro as an accommodation at UCSF. https://synapse.ucsf.edu/articles/2024/04/23/im-visually-impaired-apple-vision-pro-amazing-assistive-device

An old trick I used to use was to reduce the resolution on the monitor which would then cause most of the screen to automatically zoom. The flicker is from the FPS on the monitor and magnification - at least that's my guess. I would try lowering monitor resolution THEN magnifier and THEN color swap.

Hey all,



Working with a low vision student, and when we turn on magnifier and high contrast in windows, the screen flickers. I haven’t seen it before and having problems finding solutions. Any ideas?



Thanks,
