How to Choose a Monitor: Size, Resolution, Panel and Refresh Rate — What Matters for Work, Gaming and Study

The monitor is the one part of a computer you interact with constantly: you look at it for eight, ten, twelve hours a day. Its quality affects how comfortable your work is, how tired your eyes get and how much you enjoy games and films. Yet the choice is huge, and the specifications in shops are often confusing. Let's look at what really matters when choosing a monitor for work, gaming and study.

Choose size and resolution together

The biggest mistake is choosing screen size separately from resolution. What matters is pixel density: the higher it is, the sharper text and images look. Good combinations:

• 24 inches — Full HD (1920×1080). The classic choice for offices and budget gaming systems. Text is sharp enough.
• 27 inches — QHD (2560×1440). Probably the best choice for most people: noticeably more workspace and sharpness, without being too demanding on the graphics card in games.
• 27–32 inches — 4K (3840×2160). Maximum sharpness for text and photos, excellent for documents, photo and video work. Gaming at 4K needs a very powerful graphics card.
• 34-inch ultrawides (3440×1440) — a replacement for two monitors, handy for editing, spreadsheets and some games.

A 27-inch Full HD monitor looks grainy: text is fuzzy and pixels are visible up close. It's best to avoid that combination if you work with text.

Panel type

• IPS — good colour and viewing angles; the all-round choice for work, photos and gaming. Black looks slightly greyish in the dark.
• VA — high contrast and deep black, good for films and games with dark scenes. Viewing angles and response times are worse on budget models.
• TN — an outdated type, fast but with poor colours and viewing angles. Not worth buying today.
• OLED — perfect black, excellent contrast and speed, and a stunning picture. The downsides are price and the risk of burn-in when static elements are shown for long periods: taskbars and program interfaces.

Refresh rate

For office work 60–75 Hz is enough, although even for work 100–120 Hz makes scrolling and mouse movement more pleasant. For gaming, go for 144 Hz or more: the picture is noticeably smoother. Rates of 240 Hz and above are for esports players and fans of fast shooters. The graphics card needs to produce as many frames as the monitor can show, or the high refresh rate goes to waste.

Colour accuracy for photo and design work

If you work with photography, design or video, look at colour space coverage (sRGB, DCI-P3, Adobe RGB), factory calibration and backlight uniformity. A monitor for design work is best calibrated with a colorimeter. For ordinary work and gaming, a good IPS panel with around 100% sRGB coverage is enough.

Ergonomics and eye health

• A stand with height and tilt adjustment — the top edge of the screen should be at eye level. This reduces strain on your neck. If the stand is basic, you can use a VESA-mount arm.
• Flicker-free backlighting — less eye strain during long sessions.
• A matte finish — fewer reflections in a bright room.
• A blue-light reduction mode — can be useful in the evening.

Connectors and compatibility

Make sure the monitor and your graphics card or laptop have compatible connectors. High refresh rates and resolutions usually need DisplayPort or HDMI 2.1; older HDMI can limit the refresh rate. For laptops, a monitor with USB Type-C is convenient: one cable carries the picture and data and charges the laptop. A built-in USB hub and speakers are a nice extra.

Common mistakes

• A large screen with a low resolution — blurry text.
• A 240 Hz monitor for a weak graphics card that produces 60 frames per second.
• Connecting a gaming monitor with an old cable — the refresh rate is capped at 60 Hz even though the monitor can do more.
• The refresh rate never set in Windows — a 144 Hz monitor runs at 60 Hz for years.
• Too big a monitor on a shallow desk — you have to keep turning your head.

5. Fits a monitor arm and helps arrange an ergonomic workspace.

A real example

An accountant in Didube bought a large 27-inch Full HD monitor, expecting spreadsheets to be easier to see on a bigger screen. But the text turned out blurry, her eyes were tired within a couple of hours and she kept having to change the zoom. Our technician suggested exchanging it for a 27-inch QHD monitor with an adjustable stand, set up the scaling and connected it via DisplayPort. Her workspace grew, the text became sharp and eye strain dropped noticeably.

Before buying, it helps to see the monitor in person if you can, or at least read independent reviews with measurements. The specifications on the box won't tell you about backlight uniformity, glow in the corners, coating quality or real response times. And if the monitor is for a laptop, check in advance which connectors and refresh rates your particular laptop model supports.
