## What reviewers say

**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.)

**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.)
