Best gaming monitor deal: Dual Mode 27-inch LG UltraGear OLED is 40% off at Amazon

TL;DR: The LG 27GX790B-B 27-inch UltraGear OLED gaming monitor is on sale for $699.99 at Amazon, down from its $999.99 list price.

OLED gaming monitors are rarely where you go looking for budget upgrades, but Amazon’s latest LG UltraGear deal gives you a pretty serious price cut on one of the fastest 27-inch screens in LG’s current lineup. 

As of June 30, the LG’s 27-inch UltraGear QHD OLED gaming monitor (the 27GX790B-B model) is on sale for only $699.99 at Amazon — with a limited-time deal cutting $300 from its $999.99 list price. 

Shipped and sold by Amazon directly (instead of a third-party seller), free delivery is set for July 5 at the time of writing, or as soon as July 2 for Prime members. Amazon also shows a used “Like New” option for $664.99 through Amazon Resale, if you want to save as much as possible. Anyone wanting the new model directly from Amazon will want to stick with the $699.99 listing. 

This UltraGear is built around a 27-inch QHD OLED panel with a 2560×1440 resolution, giving you a sharper picture than 1080p without asking your PC to push full 4K. If you’re either new to PC gaming or upgrading from a much older rig, this is a very nice middle ground. 

If you’re the type who plays a lot of competitive games, you’ll be a big fan of LG’s Dual Mode: letting you switch between QHD at up to 540Hz or HD at up to 720Hz, depending on whether you care more about sharpness or pure reaction time. Add in the 0.02ms gray-to-gray response time, and games like Counter-Strike 2, Rocket League, Fortnite, and Valorant should feel seriously quick.

The OLED panel should also help with more cinematic games and streaming, with LG listing 335 nits of typical brightness, DisplayHDR True Black 500, UL Verified Perfect Black, and a 1.5M:1 contrast ratio.

That means if you’ll be playing Assassin’s Creed Black Flag Resynced or Grand Theft Auto VI in the future, you’ll be getting richer blacks, stronger contrast, and better detail in darker scenes than you’d expect from a more standard gaming monitor. 

For keeping frames extra smooth, the monitor also supports NVIDIA G-SYNC compatibility and AMD FreeSync Premium Pro. DisplayPort 2.1, dual HDMI 2.1 ports, USB-C, three USB ports, DTS Headphone:X support, and height, tilt, swivel, and pivot adjustments round out the package — so you have all the versatility you need to complete your new immersive setup and then some. 

If you fancy an extra QHD monitor, the 27-inch Odyssey G5 is now only $149.99 at Amazon. As for OLEDs, you can still grab the Samsung Odyssey OLED G9 curved gaming monitor for its lowest-ever price.
