How to Choose a Monitor: 4 Steps to Resolution, Panel, and Refresh Rate

Everything you need to know about how to choose a monitor: 4 steps to resolution, panel, and refresh rate, explained plainly.

Key decision factors

Step-by-Step Guide

Resolution determines pixel density (PPI, pixels per inch), which determines sharpness. The same resolution looks sharper on a smaller screen.

The Most Common Monitor Buying Mistakes

Buying 1080p at 27 inches: at arm's length, 27-inch 1080p is noticeably less sharp than 1440p. The pixel density (82 PPI vs 109 PPI) is visible as slightly blurry text edges and less defined UI elements.

Resolution and Size: The Current Sweet Spots

24-inch 1080p: the correct choice for competitive gaming where maximum frame rate is prioritized and GPU resources should not go to resolution. At 24 inches, 1080p is acceptable in sharpness.

GPU Compatibility: Check Before Buying

The monitor's maximum resolution and refresh rate are ceiling values, not guaranteed values. What you actually get depends on your GPU's output capability: Verify before purchasing: look up your GPU model's benchmark performance in your primary game at the target resolution and check whether it reaches the target frame rate at the settings you play at.

Connectivity: The Detail Most People Miss

One of the most common post-purchase frustrations with monitors is connecting an HDMI cable and getting lower resolution or refresh rate than expected, because the cable or GPU output was a lower HDMI version. Check both ends: what version does your GPU output?

The pixel density (82 PPI vs 109 PPI) is visible as slightly blurry text edges and less defined UI elements.

Buying a 144Hz monitor with a GPU that cannot reach 144fps: a 144Hz monitor running at 60fps provides the same experience as a 60Hz monitor.

Check that your GPU can reach the target frame rate in your most-played games before paying the 144Hz premium.

Buying HDR 400 expecting true HDR: HDR 400 monitors meet the bare minimum HDR specification (400 nits peak brightness, no local dimming) and do not deliver the HDR experience that high-end TVs and OLED monitors deliver.

Resolution and Size: The Current Sweet Spots

24-inch 1080p: the correct choice for competitive gaming where maximum frame rate is prioritized and GPU resources should not go to resolution.

At 24 inches, 1080p is acceptable in sharpness.

Not recommended for office work or content consumption at this size, the low PPI shows on text.

27-inch 1440p: the current recommendation for most users.

109 PPI is noticeably sharp at arm's length, the resolution is GPU-efficient enough to reach 144fps in modern games on mid-range hardware, and 27 inches is large enough for split-screen work without requiring head movement for full-screen reading.

GPU Compatibility: Check Before Buying

The monitor's maximum resolution and refresh rate are ceiling values, not guaranteed values.

What you actually get depends on your GPU's output capability: Verify before purchasing: look up your GPU model's benchmark performance in your primary game at the target resolution and check whether it reaches the target frame rate at the settings you play at.

A GPU that averages 90fps in a 144Hz-targeted game gets the benefit of higher-than-60Hz refresh, but does not get the full 144Hz smoothness.

Connectivity: The Detail Most People Miss

One of the most common post-purchase frustrations with monitors is connecting an HDMI cable and getting lower resolution or refresh rate than expected, because the cable or GPU output was a lower HDMI version.

Check both ends: what version does your GPU output?

What version does the monitor accept?

The lower-rated connection is the limit.

A DisplayPort 1.4 GPU into an HDMI 2.0 monitor input delivers HDMI 2.0 maximum bandwidth (4K at 60Hz), not DisplayPort 1.4 bandwidth (4K at 144Hz).

Frequently asked questions

Is 27-inch too big for a desk monitor?

At a typical arm-length desk distance (60 to 80cm), 27 inches is the most recommended size, large enough for split-screen multitasking and comfortable for single-window work. 32-inch monitors at the same desk distance can feel immersive for gaming but require head movement for edge-to-edge reading in office applications. Below 27 inches (24 inches), 1080p resolution at arm's length is noticeably less sharp than 1440p on a 27-inch monitor. For 34-inch ultrawide monitors, the same distance is comfortable for the wider field of view.

What is the difference between G-Sync and FreeSync?

G-Sync and FreeSync are variable refresh rate technologies that eliminate screen tearing by synchronizing the monitor's refresh rate to the GPU's output frame rate. G-Sync is NVIDIA's proprietary standard, requiring NVIDIA-certified monitor hardware, historically more reliable but more expensive. FreeSync is AMD's open standard, implemented without licensing fees, found on a wider range of monitors at lower price points. G-Sync Compatible is NVIDIA's certification for FreeSync monitors that pass NVIDIA's testing, allowing them to work with G-Sync on NVIDIA GPUs. Most modern gaming monitors with FreeSync Premium are G-Sync Compatible and work with both NVIDIA and AMD GPUs.

Does monitor response time matter?

For competitive gaming: yes. A 1ms GtG (grey-to-grey) response time reduces pixel persistence, which reduces motion blur. For fast-paced FPS gaming where aiming at moving targets is critical, faster response times are measurable and impactful. For office work and casual gaming: no. The motion blur from a 4ms or 8ms response time is imperceptible during document scrolling and casual game play. VA panels typically have 4-8ms response times that produce trailing on fast-moving game elements, not a problem for single-player games, a disadvantage in competitive multiplayer.

Is HDR worth paying more for?

True HDR performance requires a monitor with high peak brightness (600 nits or higher) and local dimming (the ability to dim specific zones of the backlight independently for better contrast). Budget HDR monitors (HDR 400, HDR 600 without local dimming) do not produce a meaningful HDR viewing improvement and the HDR mode often degrades color accuracy. Genuine HDR performance: Samsung Neo G7 Mini-LED (local dimming, 1000+ nits), OLED monitors. If a monitor specifies HDR 400 without local dimming, the HDR implementation is cosmetic, not functional. For content consumption where HDR matters: invest in genuine HDR capability or skip HDR entirely.
