The New OLED Monitor Tech Has a Huge Catch

Product Reviewed

ASUS 27-inch “Tandem OLED” monitor (first-generation tandem OLED monitor technology). It was tested for about a month on the reviewer’s desk and compared mainly against an AOC OLED, which the reviewer describes as the brightest OLED display they own (used for brightness comparisons).

Key Features / What Makes It Different

• Tandem OLED design (stacked OLED layers) The monitor uses a second OLED layer stacked on top of the first to boost brightness.

• Much better brightness in small highlights

  • Full-screen brightness is only slightly higher than the AOC.
  • In small-window scenarios (around 10% / 1% of the screen and smaller), the tandem OLED delivers much higher peak brightness, described as almost ~3× brighter than the AOC in those cases.

• Improved “highlight visibility” Small bright elements (e.g., neon signs, sunlight through a window, fires) look more vivid and “stunning.”

• OLED strengths remain

  • Pixel-perfect blacks
  • Excellent colors
  • Great viewing angles
  • Strong motion clarity

Setup / User Experience

• The reviewer mirrors the tandem OLED to another OLED display (an AOC) while testing.
• Early testing (mostly SDR/web browsing) made the upgrade feel subtle.
• The monitor “clicked” once the reviewer switched to HDR content (movies/games/TV), where highlight behavior became much more obvious.

Pros (As Stated)

• Meaningfully brighter highlights in HDR for small bright areas (when the brightest objects don’t fill the screen).
• In the right scenes, the improvement can make the picture “pop,” feeling like a generational leap over the AOC.
• Useful for gaming and movies, thanks to better small glare/highlight performance.
• The reviewer feels the tandem concept “works”, and that tandem OLED performs well across other device categories (mentioned broadly: TVs, phones, tablets, laptops).

Cons (As Stated)

• Large-area brightness is poor / unimpressive

  • When bright content covers more than a fraction of the screen (e.g., daytime scenes with lots of bright area), performance drops and becomes practically equal to the AOC.
  • The reviewer describes this as a serious issue, not just preference: the monitor is “literally unable to display the image the way it should look.”

• ABL behavior / brightness limiting problem

  • The reviewer suspects OLED Automatic Brightness Limiter (ABL) is responsible for the brightness collapse on larger bright areas.
  • They’re frustrated because tandem OLED TVs and even devices like iPad Pro show better large-area brightness, yet these tandem OLED monitors still limit aggressively.
  • The reviewer concludes they can’t find a clear explanation, and that this remains unresolved.

• Price / value concerns

  • New price is cited as $650 (too high for the reviewer).
  • Open-box pricing found: $450, which is closer to “possibly worth it.”

Comparisons Made

• Versus OLED mini-LED (general context)

  • OLED has traditionally been criticized for lower brightness compared with mini-LED.

• Versus the AOC OLED (direct comparison)

  • Small highlight windows: tandem OLED wins big (up to ~3× brightness at small areas).
  • Full-screen / large areas: tandem OLED is only slightly brighter and often nearly the same as the AOC.

• Versus OLED TVs / other devices (contextual)

  • OLED TVs reportedly maintain higher brightness even around 50% pure white, implying less aggressive ABL.
  • iPad Pro is mentioned as a tandem OLED example that maintains better brightness at 50% and 100% compared to most TVs.
  • The reviewer argues this suggests the limitation isn’t purely about tandem OLED tech or screen size.

Ratings / Numbers Mentioned

• New price: $650
• Open-box price found: $450
• The reviewer suggests it may be worth it if open-box pricing is about $100 more than the AOC (implied threshold).
• Brightness behavior described as:
  • Full screen: “only slightly brighter”
  • Small windows (10% / 1% / smaller): almost 3× brighter than AOC
• No formal star/percent rating was given; instead, the reviewer explicitly cancels the full-price purchase.

Overall Verdict / Recommendation

• At full price ($650): Not recommended. The reviewer says it doesn’t deliver consistent HDR brightness across larger bright scenes and can’t reproduce intended HDR luminance properly.

• At open-box pricing (around $450): Potentially worth it. Especially for users who more often watch/play content where bright elements are small highlights rather than large portions of the screen.

• Technology is promising, but the reviewer feels this first-generation tandem OLED monitor implementation is uneven due to strong brightness limiting (ABL-like behavior).

Unique Points Mentioned (Consolidated)

1. OLED is excellent overall but historically limited by brightness as a monitor versus mini-LED.
2. A “Four-Stack” concept improved OLED brightness/resistance and reduced burn-in concerns (as referenced in the discussion).
3. New monitors use tandem OLED (stacked second OLED layer) to increase brightness and reduce the classic OLED brightness drawback.
4. This tandem OLED monitor is first-generation and pricey ($650 new).
5. Open-box strategy: Best Buy open box found at $450 with manufacturer warranty.
6. Early SDR/web usage shows small differences; HDR reveals the real benefits.
7. Tandem OLED is brighter in small highlights, but the difference is subtle during normal viewing.
8. Large-area HDR brightness looks similar to the AOC, and the tandem advantage fades on larger bright content.
9. The reviewer identifies potential ABL as the cause of the large-area brightness collapse but can’t explain why monitors underperform TVs/other devices.
10. The reviewer claims the monitor can’t display HDR as intended for higher-nit mastering when bright areas are large.
11. Recommendation depends heavily on scene type and price; open-box may be acceptable, full price is not.

Speaker / Contribution Breakdown

• Single main speaker/reviewer (no separate named speakers in the subtitles).
• A sponsorship plug for an Anker power bank appears but is unrelated to monitor performance; it does not affect the product evaluation beyond briefly interrupting testing.
