I've accidentally broken my EV2795 panel and ordered the same as well as Apple Studio Display to try it, still waiting on the Studio Display to decide, hopefully 8BIT+FRC won't be an issue 🤞
I believe the panel is the same on EV2781 and yes they don't manufacture their own panels, the good thing is that they have better Quality Control over other brands.
And they seem to have fix a small QC issue over their earlier models of EV2795 which was that both bottom corners of the panel protruded a bit.
Haven't used a BenQ monitor, so maybe I'm biased towards Eizo.
