The problem with this lawsuit is it targets mostly lesser Hisense models that are cheaper because they're not as good as their better QLED / QD-LED models. I own a Hisense U8K TV (prior year's version of the current U8N), which is QD-LED but NOT on the list -- presumably because its quantum dots perform better than the models named in the lawsuit. This lawsuit is basically demanding Buick quality at less than Chevy prices; it needs to be dismissed ASAP. If you want Cadillac quality from a TV, buy an OLED; anything else, including my own TV, is a tradeoff of price for performance. (I am a licensed attorney, but not in active practice.)

Well, this should be easily verifiable. People have been checking their monitor panel manufacturers and model numbers. If their panels match non-QD model numbers then they have a case. Problem is they could be using many suppliers and sprinkle in some non-QD panels either due to supply constraints or 'cost-cutting'.
This could mean that not all TVs will be affected. And depending on the number, Hisense might argue they made a manufacturing 'mistake'.

Does this misrepresentation effect TCL's models equivalent as well?

"The plaintiff, Robert Macioce, is seeking to represent New York consumers who purchased the following Hisense TV models:

QD5, QD6, QD65, QD7, U7, and U7N series"

I would say yes, since it literally lists the models in the article, and you have that model.

I purchased a Hisense 65 in U7n last year would that qualify for the qled qualify for the lawsuit?
