What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
LG UltraGear 27GX790A-B
Only one whitelisted tester review (PCWorld, tested 2025-02-21) returned verifiable verbatim text and lab measurements for this exact model (27GX790A-B). All three quoted sentences and all four measured values (with units) were re-confirmed verbatim on the page. Candidate reviews from RTINGS, Tom's Hardware and Tom's Guide were excluded because their page bodies returned only navigation/no copyable text. PCWorld praises near-still-image motion clarity at 480Hz and per-pixel zero-nit contrast, but flags a distracting dirty-screen effect and pixelation around small fonts. (1 sourced review, 1 lab-tested.)
Praised: Motion clarity nearly as crisp as a still image at 480Hz; Exceptional contrast from per-pixel zero-nit black levels; Accurate out-of-box color (6400K vs 6500K target, gamma 2.2).
Flagged: Distracting dirty-screen effect (DSE) during use; Pixelation visible around small fonts and interface buttons; Modest SDR brightness (~250 nits sustained).
Alienware AW2725D
Three whitelisted testers (Tom's Hardware, Tom's Guide, PCWorld) lab-tested the exact AW2725D and all recommend it: a roughly $500-550 27-inch 1440p QD-OLED with rich, accurate color, inky contrast and smooth 280Hz motion that rivals pricier OLEDs. Shared gripes: no speakers, sparse ports/no USB-C video, and modest 1440p sharpness. All quotes and measured values were confirmed verbatim in the fetched source text. (3 sourced reviews, 3 lab-tested.)
Praised: Rich, vibrant QD-OLED color with wide DCI-P3 gamut coverage; Excellent value for a QD-OLED at roughly $550; Inky blacks and effectively infinite OLED contrast.
Flagged: No built-in speakers or headphone jack; Limited I/O with no USB-C video input; 1440p sharpness is modest next to 4K QD-OLED rivals.
