For most PC gamers, a 27-inch 1440p monitor at 144Hz or higher is the best balance of sharpness, smoothness and price. Choose 1080p at a high refresh rate if you play competitive shooters or have an entry-level graphics card. Choose 4K only if your graphics card is powerful enough to drive it. The monitor should match the graphics card, because it can only show the frames your PC produces.

Monitor listings are full of numbers, and most of them matter less than three things: resolution, refresh rate and panel type. This guide explains each one and shows how to match a monitor to the PC or console you already own.

Resolution: 1080p, 1440p or 4K

Resolution is the number of pixels on the screen. More pixels give a sharper picture, but your graphics card has to work harder to fill them.

Resolution Also called Best screen size Load on the graphics card Good for
1920 x 1080 Full HD, 1080p 24 inch Low Competitive games and entry-level graphics cards
2560 x 1440 QHD, 1440p 27 inch Medium Most gamers. Sharp, and still easy to run at high frame rates
3840 x 2160 4K, UHD 27 to 32 inch High Story-driven games, powerful graphics cards and creative work

Refresh rate: how smooth it feels

Refresh rate, measured in hertz (Hz), is how many times a second the screen redraws. Higher numbers make motion look smoother and controls feel more responsive.

60HzFine for office work and slower games.
144HzThe big step up. Most people notice it immediately.
240Hz+For competitive players with a PC fast enough to use it.

A high refresh rate only helps if your PC can produce the frames. A 240Hz monitor shows no benefit over 144Hz if your games run at 90 frames per second.

Match the monitor to your graphics card

Use this as a rough guide. Actual frame rates depend on the game and the quality settings you choose.

Your graphics card A sensible monitor
Built-in graphics or an older card 1080p at 60Hz to 100Hz
Entry-level gaming card 1080p at 144Hz or higher
Mid-range gaming card 1440p at 144Hz or higher
High-end gaming card 1440p at 240Hz, or 4K at 120Hz and up

If you are planning an upgrade, choose the graphics card and the monitor together.

Panel type: IPS, VA or OLED

Panel Strengths Trade-offs
IPS Accurate colour and wide viewing angles. The safe all-round choice. Blacks look grey in a dark room.
VA Deeper blacks and higher contrast. Common in curved monitors. Fast motion can smear on some models.
OLED True blacks, vivid colour and the fastest response. Costs more, and static images need some care.

Features worth paying for

  • Adaptive sync. FreeSync or G-Sync compatibility matches the screen to your frame rate and removes tearing. Most gaming monitors include it.
  • The right ports. DisplayPort is the usual choice for a PC. For a PlayStation 5 or Xbox Series X at 4K and 120Hz, the monitor needs HDMI 2.1.
  • An adjustable stand. Height and tilt adjustment matter for long sessions. VESA mounting lets you use a monitor arm.
  • Curved and ultrawide screens. Immersive for racing and simulation games. Check that your games support the wider shape.

After connecting a new monitor, open the display settings on your PC and set the refresh rate yourself. Many monitors run at 60Hz until you change it.

HDR labels vary widely. Entry-level HDR adds little, so do not pay extra for it unless the monitor is also bright enough to show it properly.

Before you order: a quick checklist

  • The resolution suits my graphics card
  • The refresh rate is one my PC or console can reach
  • The screen size fits my desk and viewing distance
  • It has the port I need: DisplayPort for PC, HDMI 2.1 for 4K at 120Hz on a console
  • The cable I need is included, or I have one
  • The stand adjusts, or I have a VESA arm

Frequently asked questions

Is a 144Hz monitor worth it?

Yes, if your PC can run your games above 60 frames per second. Motion is visibly smoother and controls feel more responsive.

Is 4K worth it for gaming?

Only with a powerful graphics card. 4K has four times the pixels of 1080p, so frame rates drop sharply on mid-range hardware. For most gamers, 1440p is the better balance.

Is 1440p the same as QHD or 2K?

1440p and QHD both mean 2560 x 1440. Some listings also call this 2K.

Can I use a gaming monitor with a PS5 or Xbox?

Yes. Both consoles support 120Hz. For 4K at 120Hz the monitor needs an HDMI 2.1 port.

Is a curved monitor better for gaming?

It is a matter of preference. A curve helps on wide screens by keeping the edges at a similar distance from your eyes. On a 24-inch or 27-inch screen it makes little difference.
