LG UltraGear 27GX704A-B

In this lg ultragear 27gx704a-b review, the LG UltraGear 27GX704A-B is the best budget Oled monitor you can buy at $399.99, and it holds the number three spot out of ten in our 2026 guide. This 27-inch screen runs QHD at 2560 x 1440 pixels with a 240Hz refresh rate and a 0.03ms response time, so fast shooters stay sharp and smear-free. Buyers agree: 4.6 stars across 489 Amazon ratings, the largest review base in the group. A 1,500,000:1 contrast ratio and 1300-nit peak brightness give it the deep blacks and bright highlights that Oled is known for, while the standard brightness sits at 275 nits. It suits gamers who want Oled speed on a mid-range budget, not photographers chasing 4K detail.

Day to day, the glossy 27-inch panel covers 98.5% of the color gamut with VESA DisplayHDR True Black 400 and HDR10 support, which means HDR games and streaming look rich rather than washed out. Adaptive sync covers both sides of the market: AMD FreeSync Premium Pro and NVIDIA G-Sync Compatible, so screen tearing stays under control whether you run a Radeon or GeForce card. On top of that, two HDMI 2.1 ports, a DisplayPort and three USB ports (two of them USB 3.0) handle a PS5, an Xbox and a PC without a hub. The stand adjusts for height, pivot, swivel and tilt, and the 15.9-pound body has a 178-degree viewing angle. Three UL certifications for anti-glare, flicker-free and low blue light help during long sessions, and Dynamic Action Sync reduces input lag.

That price is the real story. Compared with the 4K models in this guide, the LG 27GX704A-B costs about $400 less and still delivers 240Hz Oled motion, which means you can put the savings toward a GPU. Even so, two trade-offs matter. First, LG covers this monitor for 2 years, while MSI, Samsung and Alienware offer 3 years. Second, 1440p at 27 inches steps behind 4K for photo and video editing, so creative professionals should look higher up the list. Meanwhile, the 489 ratings and 4.6-star average make it the safest sub-$500 Oled buy here. If you want a fast, bright Oled gaming monitor without a four-figure bill, this is the one to get.
