Real 27-Inch 4K 144Hz Gaming Monitors and Close Alternatives
Typing "27 inch 4K 144Hz" into a search bar is really asking one question: can you get sharp 4K detail and smooth, fast motion in the same 27-inch screen, without one canceling out the other. That combination needs real bandwidth (HDMI 2.1 or DisplayPort 1.4 with DSC) and a panel actually rated for it — a lot of 27-inch 4K monitors top out at 60Hz because they're built for editing and office work, not gaming.
The options below split into two groups. A couple hit the literal spec you searched for. The rest are close alternatives worth knowing about if you're willing to trade resolution for refresh rate, or size for panel technology, since the pool of true 27-inch/4K/144Hz panels is small.
Picks are ranked by how closely they match all three numbers in your search, then by what you'd gain or give up by stepping outside that exact spec.

What to look for
The number that actually matters here is whether the monitor's ports can carry a full 3840x2160 signal at 144Hz. HDMI 2.0 can't do it — you need HDMI 2.1 or DisplayPort 1.4 (often with Display Stream Compression). If a listing doesn't mention HDMI 2.1 or DP 1.4, assume the 144Hz figure only applies at a lower resolution. Response time is the second thing to check: look for GtG or MPRT numbers rather than trusting refresh rate alone, since a fast panel with sluggish response can still ghost in motion.
If a true 27-inch 4K 144Hz panel isn't available or affordable, the tradeoff usually goes one of two ways: drop resolution to 1440p and keep 165Hz-240Hz on a similar-size screen, or keep 4K and accept 120Hz. Either compromise still beats a 60Hz 4K monitor for competitive or fast-paced games, so weigh what you'd actually notice — sharper text and detail, or smoother fast motion — before deciding which axis to give up.
