Buying a projector without rainbow effect up to 1000 euros

Hello,

I bought a Benq TH575 projector in 2024 but, after a few months, I realized that the rainbow effect was very visible and that it bothered me too much.

So, I sold it and I'm now looking for an entry/mid-range projector, up to 1000 euros max, and with a much less visible rainbow effect. I guess the safest thing to do is to buy an Epson?

Here are my specifications:
- localisation: Belgium (Europe)
- use: cinema - I don't care about the speaker built into the projector
- dimensions: +-4 meters depth, +-2 meters image width
- installation: rear shelf
- the projector will be used mainly at night
- connection via apple tv 4k or mac
- used mainly for movies - I don't care about the projector's built-in speaker

Thank you so much.
