## 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.)

**Samsung Odyssey OLED G6 (LS27FG602S)** — Three whitelisted outlets (Tom's Hardware, PCWorld, TechRadar) each reviewed this exact 27-inch 500Hz QD-OLED (S27FG60/G60SF). All rate it a top-tier OLED for motion clarity, speed, and color, while dinging its 1440p sharpness, missing USB-C, and limited SDR presets. Tom's Hardware and PCWorld ran lab measurements; TechRadar was hands-on with no independent numbers. Several Tom's Hardware quotes/measurements sat on later review pages not captured by the fetch and were dropped. (3 sourced reviews.)
