What reviewers say about the 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.
