A dash means the manufacturer does not publish that figure or we could not verify it. We never fill gaps with estimates.

Size, resolution, panel, refresh rate and response time are each checked against the manufacturer's listing on Amazon.es. Anything we could not confirm shows as “—”: we would rather leave a gap than invent a figure.

The review

This monitor settles the classic high-end dilemma of choosing between resolution and speed. Here you get 4K and 240 Hz at once, so demanding games do not look soft and competitive ones do not feel slow.

Being QD-OLED, every pixel switches off completely. Contrast cannot be expressed with the usual figures because black is black, with no backlight leaking through, and quantum-dot colour is highly saturated without looking artificial. In motion, 0.03 ms makes the idea of smearing stop applying.

The trade-offs are those of the technology: sustained brightness in very bright scenes does not match a good Mini-LED, and retention is worth considering if you spend whole working days with fixed interfaces. At 32 inches, 4K gives about 140 pixels per inch, an excellent density that will probably want some system scaling for comfortable work.

In its favour

  • 4K and 240 Hz without choosing
  • Absolute black and QD-OLED colour
  • 0.03 ms: instant response
  • 140 ppi, outstanding sharpness

Against it

  • High-end price
  • Sustained brightness below a Mini-LED
  • Fixed interfaces need care because of retention

Best for: Anyone who wants a single monitor that does everything at the highest level and has the card to drive it.

What the reviews say

Editorial assessment, not a review summary: it is one of the few monitors that does not force a choice between resolution and speed. What you take on is the price and the care an OLED asks for if you work with fixed interfaces for hours.
