42 facts in comparison
Two Mini-LED 4K monitors at similar money, both doing the thing that separates real HDR from a sticker: dividing the backlight into over a thousand independently dimmed zones.
The differences are at the margins — peak brightness, colour coverage, and whether the stand pivots. Read the mounting and stand rows carefully, because on displays this closely matched the ergonomics are more likely to decide it than the panel figures.
No standout advantages.
The spec sheet pulls in both directions. These are the gaps big enough to shape the decision — with the actual figures, and what each one means in real-world use.
Higher brightness makes HDR highlights pop.
Rotate to portrait orientation.
There is no single answer — it depends on what you will actually use it for. Match your priority to the pick below.
