How they differ in real use
Built from our 4k gaming monitors scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Samsung Odyssey OLED G8 G80SH 32" and the LG UltraGear 32GX870A-B made our Top 5 4K Gaming Monitors, at #1 (best overall) and #4. The 2026 successor to the Odyssey OLED G8 G80SD that used to hold this spot (Amazon no longer sells the G80SD new). It keeps the 31.5" 4K QD-OLED format at 240Hz with a 0.03ms response, but steps up to VESA DisplayHDR True Black 500 where every other OLED in this list is certified True Black 400, and adds DisplayPort 2.1 (UHBR20) alongside two HDMI 2.1 inputs and 98W USB-C. RTINGS names it the best Samsung monitor it has reviewed and finds its matte Glare Free coating handles reflections much better than the glossy MSI MPG 321URX. The higher HDR certification and DisplayPort 2.1 bandwidth put it ahead of the ASUS PG32UCDM; the trade-offs are a hazier image and purple-tinted blacks in a bright room, some VRR flicker in dark games, and no speakers, smart TV apps or KVM switch. Dual-mode versatility: 4K/240Hz for immersive games or FHD/480Hz for competitive esports. MLA+ delivers 1300 nit brightness with webOS smart features and USB-C 90W charging, and its price has eased well below the rest of this lineup.
