Do All The Acer ConceptD Laptops have DisplayHDR1000 ? Which ConceptD is Best For Video Editing?

I don't think they are updating each of the model lines each year, due to the lower sales volume on these higher end designs. That's why the ConceptD 7 is lagged in comparison to the ConceptD 5. I expect they'll update the 7 line next year, likely with 14th gen, though they may do it or a 13th gen version later this year. We can only guess… As to HDR 1000, that's usually more associated with monitors than with laptop displays. I would be surprised if any of the current ConceptD models support it on their display, but they might for external displays.

Adobe assumes their customers will all be working on a desktop environment, since desktops have a lot fewer limitations to the display. Likely they are right in regards to the bulk of their users, but obviously they are missing out on a decent and growing percentage.
