The best gaming monitor is the one that matches the machine plugged into it. A 4K screen at 144 Hz is wasted on a graphics card that can only manage 60 frames per second at that resolution, and a 240 Hz panel does little for a console that tops out at 120. Start with what your PC or console can actually output, then pick size, resolution and refresh rate around it.
For most people the sweet spots are simple: a 24 to 25 inch 1080p screen at 144 Hz or more for fast competitive games, a 27 inch 1440p screen at 144 to 170 Hz as the all-rounder, and a 32 inch 4K screen for slower, more cinematic games or a current console.
After that, panel type, adaptive sync and connections decide whether the monitor feels smooth in practice. The sections below explain each of these, with a checklist at the end.
Size and resolution go together
Resolution is the number of pixels. The bigger the screen, the more pixels you need for a sharp picture at normal desk distance.
| Size | Resolution | Typical use |
|---|---|---|
| 24 to 25 inch | 1920 x 1080 (Full HD) | Competitive shooters, smaller desks, mid-range graphics cards |
| 27 inch | 2560 x 1440 (QHD) | All-round gaming, the popular middle ground |
| 32 inch | 3840 x 2160 (4K UHD) | Single-player games, consoles, work and films |
| 34 inch and up, ultrawide | 3440 x 1440 | Racing, flight sims, strategy, productivity |
A 27 inch screen at 1080p can look soft up close, while a 24 inch 4K screen packs in more detail than most people notice in games and asks a lot of the graphics card. Desk depth matters too: a 32 inch screen on a shallow desk sits uncomfortably close. The gaming desks range lists depths, so measure before you choose the screen.
Refresh rate and response time
Refresh rate, in hertz (Hz), is how many times a second the screen updates. A 60 Hz monitor shows up to 60 frames per second; a 144 Hz monitor shows up to 144. Higher refresh rates make motion look smoother and reduce the delay between moving the mouse and seeing the result.
- 60 to 75 Hz: fine for strategy games, office work and many console games.
- 120 to 170 Hz: a clear step up for most PC gaming and the current consoles.
- 240 Hz and above: aimed at competitive players in fast shooters, and only useful if your PC can hold very high frame rates.
Response time, often quoted in milliseconds as grey-to-grey (GtG), is how quickly pixels change colour. Slow pixels leave smearing behind moving objects. Manufacturer figures such as 1 ms are measured in different ways, so treat them as a rough guide rather than a precise comparison between brands.
Panel types: IPS, VA, TN and OLED
The panel technology affects colour, contrast and viewing angles. Expert Reviews describes VA panels as high in contrast with weaker viewing angles, and IPS panels as vivid in colour with lower contrast.
- IPS: good colours and wide viewing angles. The most common choice for all-round gaming monitors.
- VA: deep blacks and strong contrast, which suits dark games and films. Some VA panels show dark smearing in fast motion.
- TN: older and cheaper technology with fast response but weaker colours and viewing angles. Still found in some esports monitors.
- OLED: each pixel lights itself, so blacks are perfect and response is very fast. Prices are higher, and static images such as HUDs and taskbars carry a risk of burn-in over time, so check the warranty.
Panel type is only a rough guide. Two IPS monitors can perform very differently, so read the full specification rather than relying on the label.
Adaptive sync, HDR and console support
Screen tearing happens when the graphics card and monitor are out of step. Adaptive sync fixes this by letting the monitor follow the frame rate. On PC this is usually AMD FreeSync or Nvidia G-Sync, and many monitors are listed as G-Sync compatible. Consoles use HDMI variable refresh rate (VRR).
For PlayStation 5 and Xbox Series X, Expert Reviews recommends HDMI 2.1 as a minimum if you want 120 Hz or VRR. A monitor with only HDMI 2.0 still works, but at lower settings. HDR labels vary widely; the same review suggests looking for VESA DisplayHDR 600 certification and local dimming for HDR that makes a visible difference.
Connections and your graphics card
Check the ports before you buy.
- DisplayPort is the usual choice for high refresh rates on a PC.
- HDMI 2.1 matters for consoles at 4K and 120 Hz.
- USB-C with video lets some laptops connect with one cable.
- A USB hub on the monitor is handy for keyboard, mouse and headset.
Then check your graphics card. Running 1440p at 165 Hz or 4K at 144 Hz in modern games takes a powerful card. If your current card struggles, a 1080p or 1440p screen will give a smoother result than 4K. The graphics cards and desktop ranges show what is available if you plan to upgrade the whole setup. Pair the new screen with the right keyboard using the guide to choosing a gaming keyboard.
Ergonomics
A good stand adjusts for height, tilt and ideally swivel. The top of the screen should sit at or slightly below eye level, roughly an arm’s length away. If the stand only tilts, a monitor arm with a VESA mount can fix that later; check the VESA size in the specification. All monitors are listed in the computer monitor range.
Quick checklist
- Check what your PC or console can output first.
- 24 inch for 1080p, 27 inch for 1440p, 32 inch for 4K.
- 144 Hz or more for PC gaming, 120 Hz for current consoles.
- IPS for all-round use, VA for contrast, OLED for the best image.
- FreeSync or G-Sync compatible on PC, HDMI 2.1 with VRR for consoles.
- DisplayPort for high refresh rates on PC.
- Height-adjustable stand or VESA mount.
Common questions
Is 1440p worth it over 1080p?
On a 27 inch screen, yes for most people. The picture is noticeably sharper, and many mid-range graphics cards can run 1440p at high refresh rates in most games.
Do I need a 4K monitor for a PS5?
No. A 1080p or 1440p screen works, and 60 Hz is fine for many games. For 4K at 120 Hz and VRR you need a monitor with HDMI 2.1.
Does response time really matter?
It matters most in fast games, where slow pixels cause blur. Compare independent reviews rather than relying on the quoted millisecond figure.
