    I've noticed that the HUD brightness flickers subtly. Hard to see when the car's moving, but sitting still I see it. I can't find any threads on this, so wondering if it's just me.

    (Thanks for your feedback! This is a 2018 Prius Four. And it's a small dimming where it stays at full brightness for 4-10 seconds, then dims subtly for 2-4 seconds. Not any kind of flashing. I first saw it in the evening, not yet dark but not full daylight, and assumed it might be something like shadows and light falling on a sensor that adjusts its brightness. I haven't noticed it in bright light, and can't remember if I've seen it at night. I have seen it in our underground garage. When the car's moving, there's enough motion of things that I would hardly notice it if I hadn't been sensitized in a stopped car.)

    I have not noticed it in mine. I will take extra effort to see if it is happening.

    The ambient light sensor in the front of the centre of the windscreen decides when to dim the screens when entering tunnels etc. Perhaps the ambient light is on the cusp of dimming the brilliance of the HUD. Any ideas?

    I can see mine adjusting brighter/dimmer to the varying light conditions all the time so its not just in the dark that it dims.

    Whether or not it does not auto adjust if you have the brightness all the way up or down I don't know.

    It could be the HUD automatically adjusting the brightness?

    The auto-dim when the vehicle is stopped is normal.
