The Gigabyte M27U is the best 27-inch 4K gaming monitor for most PC players because it pairs a 160Hz IPS panel with HDMI 2.1, USB-C and a proper KVM switch. A 27-inch 4K screen gives games crisp detail without taking over a desk, but the right choice still depends on whether you need multi-device control, a simpler gaming-first display, or frequent console use.
What makes a 27-inch 4K gaming monitor worth buying?
At this size, 3840 by 2160 delivers very dense text and fine game detail, so it suits players who also browse, edit, or work at the same desk. The tradeoff is GPU load: a demanding game needs considerably more graphics power at 4K than at 1440p. A high refresh ceiling remains useful because less demanding titles, older games, and adaptive-sync operation all benefit from it. For a new PC, look for DisplayPort 1.4 with compression and enough HDMI bandwidth for the devices you actually own.
All three picks use IPS-based panels and offer a fast refresh rate, but their connections separate them. The M27U runs at 160Hz and adds a KVM button, USB-C video, and a USB hub. ASUS also targets the PC desk with 160Hz Fast IPS, USB-C and a tripod socket, while LG's 27GR93U-B is a 144Hz model with HDMI 2.1, G-SYNC compatibility and FreeSync Premium. None is an automatic answer for every room: stand adjustment, cable routing, and your mix of PC and console hardware deserve equal attention.

Best overall: Gigabyte M27U
Gigabyte M27U
The Gigabyte M27U earns the overall badge because it combines a 27-inch 3840 by 2160 SuperSpeed IPS panel, a 160Hz maximum refresh rate, and an unusually useful connection set. It has two HDMI 2.1 ports, DisplayPort 1.4, USB-C video with up to 18W power delivery, plus a built-in KVM switch and three downstream USB ports. That makes it the sensible choice for someone who alternates between a desktop PC and a work laptop without moving keyboard and mouse cables. It also supports DisplayHDR 600 and has a height-adjustable stand. The limitation is that 18W USB-C charging is modest for many laptops, and its HDMI inputs top out below its 160Hz PC ceiling. Buy it for a mixed-use desk, not if you only need one simple console input.
Pros
- 160Hz 4K IPS panel gives PC games a higher refresh ceiling
- KVM switch shares keyboard and mouse between a desktop and laptop
- USB-C video, two HDMI 2.1 ports and three USB downstream ports reduce adapters
Cons
- USB-C power delivery is limited to 18W for charging larger laptops
- HDMI 2.1 is best suited to 4K 144Hz rather than the 160Hz maximum
Best for a modern PC desk: ASUS ROG Strix XG27UCS
ASUS ROG Strix XG27UCS
The ASUS ROG Strix XG27UCS is the focused pick for a single powerful PC that still needs flexible desk connectivity. Its 27-inch Fast IPS screen runs at 4K and 160Hz with a quoted 1ms gray-to-gray response time, and ASUS specifies 130 percent sRGB coverage. USB-C provides a clean way to connect compatible laptops or compact PCs, while DisplayWidget Center lets supported users change monitor settings from Windows instead of relying only on the rear joystick. The stand includes a tripod socket, a small but practical feature for a webcam or light. It earns this badge for the modern PC-oriented feature mix rather than for all-purpose switching. Its main compromise is the single HDMI 2.1 port, so it is less convenient than the Gigabyte for several HDMI devices, and its HDR400 class is not a substitute for high-end local-dimming HDR.
Pros
- 160Hz Fast IPS panel suits high-frame-rate PC games at 4K
- USB-C input keeps a compatible laptop or mini PC connection tidy
- DisplayWidget Center and the tripod socket improve a streaming or webcam desk
Cons
- One HDMI 2.1 port limits direct connections for multiple consoles
- HDR400 capability is modest beside displays with stronger HDR hardware
Best for console and PC switching: LG UltraGear 27GR93U-B
LG UltraGear 27GR93U-B
LG's UltraGear 27GR93U-B is the straightforward choice for players who want a 27-inch 4K screen that can serve both a gaming PC and modern HDMI hardware. The IPS panel reaches 144Hz, supports a 1ms gray-to-gray specification, and is listed as NVIDIA G-SYNC Compatible with AMD FreeSync Premium. Its HDMI 2.1 connectivity is valuable when a console needs a 4K high-refresh signal, and the monitor also includes DisplayPort 1.4, DisplayHDR 400 support, and LG's Black Stabilizer game feature. Choose it when you prefer a familiar gaming-monitor layout over a USB hub-heavy workstation display. The meaningful limitation is that it stops at 144Hz rather than 160Hz and lacks the M27U's KVM and USB-C workflow, so it is less attractive for one-keyboard, two-computer setups.
Pros
- HDMI 2.1 is useful for a current console alongside a DisplayPort gaming PC
- G-SYNC Compatible and FreeSync Premium support broaden variable-refresh choices
- Black Stabilizer can make dark in-game areas easier to distinguish
Cons
- 144Hz maximum is lower than the 160Hz Gigabyte and ASUS options
- No integrated KVM or USB-C workflow for sharing peripherals between computers
How to choose between these three monitors
Start with the cables on your desk. A desktop and laptop sharing one keyboard, mouse, and screen favor the M27U because its KVM and USB hub solve a real daily nuisance. A desktop-only player who values 160Hz, USB-C flexibility, and a camera-ready stand should consider the ASUS. The LG makes sense when the monitor will frequently swap between a PC and one console, where its two-display gaming identity and HDMI 2.1 support are easier to use than workstation features.
Do not assume that the highest refresh number is the only performance measure. At 4K, your graphics card and game settings determine whether 144Hz or 160Hz is reachable. Check the ports on the GPU, whether your laptop needs more than 18W over USB-C, and whether your console needs an HDMI port permanently available. Finally, measure the desk and confirm the stand travel or VESA plan before ordering. These are flat 27-inch displays, yet their stands and rear connections still need room.
FAQ
Is 27 inches too small for a 4K gaming monitor?
No. A 27-inch 4K panel has high pixel density, which makes UI text and fine distant detail look sharp at a normal desk distance. Some players prefer a larger screen for couch-style viewing, but 27 inches is easier to position close to a keyboard and mouse. Use operating-system scaling if text appears smaller than you prefer.
Do I need HDMI 2.1 for 4K gaming?
It depends on the device. DisplayPort 1.4 with compression is common for a gaming PC, while HDMI 2.1 is particularly useful for recent consoles and for high-bandwidth HDMI signals. Confirm the exact refresh and resolution modes supported by your graphics card or console, cable, and chosen monitor instead of assuming every HDMI port behaves the same way.
Is a KVM switch useful in a gaming monitor?
It is useful when two computers share the same monitor, keyboard, and mouse. The M27U's KVM can reduce repeated cable changes between a desktop and a laptop. If you only connect one PC and one console, a KVM is less important because consoles generally do not use the same keyboard-and-mouse workflow.
