Choosing a gaming monitor: how to compare picture quality, speed and connections

Buying a gaming monitor seems simple: choose a large screen with a high refresh rate and a low response time. Yet many buyers pay for specifications that do not match their computer, games or workspace. For example, a 240Hz monitor is of little use if your PC cannot achieve a high frame rate in your favourite game. And a large ultrawide screen will not automatically fit on every desk.

The most common pitfalls:

  • Looking only at the highest refresh rate. 240Hz or 320Hz sounds appealing, but the graphics card and connection must also be able to deliver that frequency.
  • Comparing response times without considering the measurement method. A value measured in GtG, MPRT or a minimum factory setting cannot be compared like-for-like.
  • Assessing resolution and screen size separately. Full HD on a 27-inch screen looks less finely detailed than QHD at the same size. A 4K monitor also requires more graphics processing power.
  • Overlooking connections and adjustability. A monitor without height adjustment or with a limited HDMI version can be inconvenient in everyday use.

The most important specifications of a gaming monitor

1. Resolution and screen size

The resolution determines how many pixels the screen displays:

  • Full HD: 1920 × 1080. A practical choice for affordable systems and high frame rates.
  • QHD or WQHD: usually 2560 × 1440. This offers more detail than Full HD without the heavy demands of 4K.
  • 4K: 3840 × 2160. Suitable for sharp images, creative applications and large screens, but more demanding on the graphics card.
  • Ultrawide: for example 3440 × 1440 or 5120 × 1440. Useful for multitasking and wide game images, provided the game supports it.

For a 24- or 25-inch screen, Full HD is often a sensible choice. At 27 inches, QHD offers a balance between sharpness and performance. A 34-inch ultrawide monitor provides extra workspace, while a 49-inch model requires a great deal of desk space.

2. Refresh rate and response time

The refresh rate is expressed in hertz. A 165Hz monitor refreshes the image more often than a 60Hz screen; a 240Hz monitor is mainly of interest for competitive gaming and powerful PCs. Do not just look at the number: also check which port supports the stated speed.

Response times are often listed as 1ms, 0.5ms or 0.03ms. Check whether this refers to GtG or MPRT. A low quoted value does not automatically mean that every image scenario will deliver the same motion clarity. Overdrive settings can also affect visible artefacts.

3. Panel type, synchronisation and connections

An IPS panel is generally known for wide viewing angles and useful colour reproduction. According to product specifications, VA panels often offer higher static contrast. An OLED gaming monitor or QD-OLED monitor uses self-emissive pixels and is supplied with specifications for deep blacks and extremely low response times. With OLED, it is sensible to check the user manual and screen-care features, especially if you regularly display static windows.

FreeSync and G-SYNC Compatible are synchronisation technologies that align the monitor’s refresh rate with the image output from the graphics card. Always check which feature is officially stated in the product information. For some models, G-SYNC may be listed as working, but it may not have been officially tested or certified.

Also look out for:

  • HDMI and DisplayPort: check the version and maximum resolution at the refresh rate you want.
  • USB-C: useful for laptops, particularly if the monitor can also transmit video and power. Check the exact wattage.
  • VESA mounting: useful for a monitor arm or wall bracket.
  • Ergonomics: height adjustment, tilt, swivel and pivot can make a noticeable difference during extended use.

Recommended models by user profile

Suitable for: Budget-conscious beginners
ASUS TUF Gaming VG249Q3A Computer Monitor

ASUS TUF Gaming VG249Q3A

Why it suits this profile: This 23.8-inch Full HD IPS model combines a 180Hz refresh rate with a quoted response time of 1ms. It is therefore suitable for anyone looking for their first gaming monitor without moving straight to QHD or OLED.

How this product avoids the pitfall

The resolution and size are easy to combine with an average gaming PC. The product information also lists FreeSync and HDMI 2.0.

Main benefit & highlights

IPS panel, 180Hz, FreeSync and VESA 100 × 100 mm; the stand can be tilted.

MSI MAG 272QP QD-OLED X24

MSI MAG 272QP QD-OLED X24

Why it suits this profile: This 26.5-inch QD-OLED gaming monitor offers WQHD resolution, 240Hz and a quoted 0.03ms GtG response time. It is a good match for gamers who place a high value on contrast, colour and fast-paced action.

How this product avoids the pitfall

The product specifications list both WQHD and 240Hz, so sharpness and speed do not depend on a single marketing figure. However, check that your graphics card supports this combination.

Main benefit & highlights

QD-OLED panel, DisplayHDR True Black 400, Adaptive Sync, FreeSync Premium and G-SYNC Compatible; height adjustment and pivot are included.

Suitable for: Specific uses & intensive users
Alienware AW2525HM Computer Monitor

Alienware AW2525HM

Why it suits this profile: For competitive players who prioritise speed above all else, this 24.5-inch Full HD model offers a stated refresh rate of 320Hz and 0.5ms GtG. The screen also features height adjustment and pivot.

How this product avoids the pitfall

The Full HD resolution reduces the graphics load compared with QHD or 4K. The stated 320Hz is mainly worthwhile when your PC can also produce enough frames.

Main benefit & highlights

Fast IPS panel, HDMI 2.1, DisplayPort 1.4, FreeSync Premium and G-SYNC Compatible according to the product specifications.

Suitable for: Home workers and multitaskers

Frequently asked questions about gaming monitors

Is 165Hz noticeable when gaming?

A 165Hz monitor can display movement more times per second than a 60Hz model. The difference is most relevant when your PC achieves a comparable frame rate. For slower-paced games, office work and films, a lower refresh rate is often sufficient.

Is OLED suitable for extended use?

An OLED panel can deliver strong contrast and a low quoted response time. During extended use with static elements, such as taskbars or fixed windows, it is sensible to use the built-in screen-care features and follow the manufacturer’s instructions. Actual lifespan depends on usage, brightness and settings.

Does a large monitor use a lot of power?

Power consumption varies depending on the panel type, resolution, brightness and energy class. Check the EU energy label and the stated consumption for SDR and HDR. A large ultrawide screen or a 4K monitor may use more power than a smaller Full HD model. Switch the screen off or use sleep mode when you are not using it.
