I’ve had my 530 for around 2 months. The first few rides were outside with the backlight on, the last 5 weeks have been inside. Went for my first outdoor ride today for a while but had the backlight turned OFF.
It was a late afternoon Autumn ride here in the hills so a lot of it was in the shade. I found the screen very dark and hard to read. If I turn the backlight on (I have the Di2 buttons set to turn on the backlight) the screen was easy to read. I found though, that if I rotated the 530 Ninety degrees, I could read it just fine, almost like the screen polarisation is 90 degrees out.
My Oakleys are Polarised, if I look at the 530 in it’s correct orientation through the glasses, it’s easier to see than if I look under them. If I turn on the backlight it is easy to see the screen.
is this normal?
