I have been using a matte screen protector since I got my ipad and man watching media on it is horrible. Also, I need to keep my ipad at 85-90% brightness otherwise it feels too dull. I want to remove it but its so much easier to write with the protector on. I think my ipad had coating issues since day 1 since some spots were slippery, but i just "owned up" and got a screen protector. Thinking about it, I should have returned it and re-ordered it but I didnt want to wait 2 months or get a refurbished device through replacement.
What’s the brand of your matte screen protector?
I think the quality is differ from one brand to another.
I use SwitchEasy, and I don’t find problem using regular brightness on my iPad Pro. It does not darkens the screen.
Also there‘s no grainny nor rainbow effect on it.
Glare is significantly reduced.
The only downside is reduced contrast and clarity which in given time, I can get used to it.
Something I would expect and trade from finger print oils and screen glare when using naked screen.
