Heads up: some links here pay us. If you buy through an EcoFlow or eufy link we may earn a commission, at no cost to you (that's Awin, in some countries). Amazon and other shop links pay us nothing right now. I haven't tested these products myself unless the page says so; the picks come from the specs and listings, and I'll tell you when I'm not sure.

How This Was Researched
I compared the Amazon.com listings, maker spec sheets and owner ratings for four 4K gaming monitors. Prices, ratings and stock were read from the Amazon.com listings on 5 October 2026 (US delivery). I have not tested these products myself. I cannot measure response time, input lag or color from a listing; the figures here are the makers'. The old LG 27GR95QE, Samsung Odyssey G8 (G80SD), ASUS PG27AQDM and Alienware AW2725DF were out of the 4K bracket or unavailable.
Frequently Asked Questions
It needs a graphics card that can run 4K at those frame rates. Dual-mode monitors let you drop to Full HD at a higher refresh rate.
OLED panels list faster response and deeper blacks, per the makers. They cost three times as much here; I have not compared them.
