## 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.)

**BenQ PD2706UA** — Two whitelisted testers bench-tested this exact BenQ PD2706UA: Tom's Hardware (7 June 2023) and TechRadar (7 July 2023). Both rate it a near-flawless professional 27-inch 4K display with strong value, praising the included ergonomic C-Clamp arm and the Hotkey Puck. TechRadar measured an average Delta E of 1.12 with 96% P3 / 100% sRGB / 89% Adobe RGB coverage; Tom's Hardware confirmed over 95% DCI-P3 coverage out of the box. Both flag 60Hz-only refresh with no Adaptive-Sync; TechRadar also flags weak built-in speakers. Non-whitelist blogs excluded. (2 sourced reviews.)
