## 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.)

**ASUS ROG Swift OLED PG27AQDP** — One whitelisted tester source (Tom's Hardware, lab-measured, published 2024-09-04) was verified for the ASUS ROG Swift PG27AQDP. All four quotes and all eight measured values were re-confirmed verbatim against the review. Tom's Hardware calls the PG27AQDP the pinnacle of premium gaming monitors, measuring a 400-nit SDR peak, 1,300-nit HDR highlights, 709-nit 25% HDR window, over 97% DCI-P3, and 15ms total input lag at a tested 480Hz QHD. (1 sourced review.)
