How to Buy a Computer Monitor
This quick guide helps you choose a monitor that fits your desk, workflow and budget. It covers the most important factors, the main types available, key specifications to check, where to buy, common mistakes to avoid and short expert tips to act on now.
Key factors to consider
- Size and aspect ratio - 27 inch is a common all-round size; 34 inch and 21:9 ultrawide screens are great for multitasking and video timelines but need more desk depth.
- Resolution and pixel density - Full HD is fine for 27 inch budget screens; ultrawide QHD (3440x1440) gives more workspace and sharper text.
- Refresh rate and response time - 100Hz is a smooth step up from 60Hz; 144Hz to 165Hz plus 1ms response help competitive gaming.
- Panel type and colour accuracy - IPS panels offer wider viewing angles and consistent colour; look for sRGB coverage if you do photo or video work.
- Ergonomics and mounting - Height, tilt and swivel adjustments and VESA compatibility matter for long sessions and multi-monitor setups.
- Eye comfort and extra features - Flicker-free tech, low blue light modes, HDR support, picture-by-picture and adaptive sync (FreeSync/G-Sync compatibility) can all be useful depending on needs.
Types and who they suit
- Standard 16:9 24 to 27 inch - Best for typical office work, browsing and compact desks.
- High refresh 24 to 27 inch - Best for gamers who want fast motion and low input lag.
- Curved ultrawide 34 inch (21:9) - Best for multitaskers, video editors and immersive media playback.
- Budget curved or flat 27 inch - Good value for gamers who want immersion without a big price tag.
Important specs to check and quick buying actions
- Resolution: Match resolution to size so text is sharp. For 34 inch ultrawide choose QHD; for 27 inch FHD may be acceptable but QHD is clearer.
- Refresh rate and sync: Pick 100Hz+ for smoother motion. If gaming, get adaptive sync to avoid tearing.
- Response time: Lower ms reduces ghosting. 1ms is ideal for fast-paced gaming; 4-5ms is fine for general use.
- Colour: Look for sRGB 99% or listed colour coverage if you edit images or video.
- Ports and compatibility: Confirm HDMI/DisplayPort and that your laptop or GPU supports the monitor resolution and refresh rate.
- Ergonomics and mount: Choose a height-adjustable stand or VESA mount if you use an arm. Measure desk depth for curved screens.
- Warranty and returns: Verify return window and dead-pixel policy before buying.
Where to buy, mistakes to avoid and expert tips
- Try in store if colour accuracy or curve comfort is critical.
- Buy online if you value price and free shipping but confirm the return policy and warranty.
- Buying a screen that is too large for your desk without measuring first.
- Assuming your computer can drive a high resolution at high refresh - check GPU outputs.
- Overvaluing HDR claims on budget monitors - real HDR needs high peak brightness and wide gamut.
- Ignoring stand adjustability and VESA if you plan to mount or adjust height.
- Prioritise resolution and panel type for creative work, refresh rate and low response for gaming.
- For multitasking pick an ultrawide QHD if your workspace fits it.
- Check user reviews for backlight bleed and uniformity before buying.
- Calibrate the display or use built-in colour presets for the best out-of-box colour.
Final Thoughts
Measure your desk, set a clear priority list (office, creative, gaming), and pick the screen that matches that priority. If in doubt, test a display in person and confirm online return and warranty terms before purchase. Small checks now save time and money later.
