Does my Sony A90J have a dirty screen?

Hello all,

I'm an Australian user. I've recently purchased a Sony A90J and overall I'm pretty blown away by the picture quality. I will primarily be using it to play films as I'm a huge cinema buff.

I've tested for dirty screen effects using some Youtube videos, playing them natively from the TV screen:

I've taken some pictures as well, but to be honest I can't tell conclusively if I have dirty screen effect or not. In the first test any kind of dirty screen element seems to be minimal and in the second test dirty screen seems only to be an issue in the really dark uniform colours. Should I still be concerned?

I'm also loathe to send it back, because of the scarce availability of the Sony A90J in Australia (Due to Covid).

In the opinion of you users, does my Sony A90J have dirty screen effect and should I ask for it to be replaced?

You’ll find issues with any display if you go looking with test patterns. The best thing is to just binge watch movies and shows during your return period. You could focus on films with an emphasis on dark and light scenes, like IT, Halloween etc., or The Shining, The Thing or The Grey. If no issues or defects become apparent in the shadows, or in the bright snow, then I really wouldn’t worry about it.

Just enjoy your superb TV.

Looks good to me. No colour tinting at all, which is IMO the worst flaw to look out for because that often is visible in day to day use.

If you can't see any defects in normal viewing don't go looking for them with test slides and enjoy your great tv.
