There's no such thing as “the best gaming monitor” – only the screen that fits your games, your GPU and your desk. In this buying guide, you'll learn which specs really matter and which marketing labels you can put in perspective. At the end, you'll find five well-known models, sorted by use case.
Transparency: We haven't tested these monitors ourselves. Specs come from the manufacturers and the verified Amazon.de product pages (as of September 2026). We deliberately don't list prices because they change all the time – you'll see the current price directly on Amazon.de.
The key criteria at a glance
1. Size
- 24–25 inch: classic for competitive shooters (Valorant, CS2). Full HD pixels look especially sharp; targets stay in the central field of view.
- 27 inch: the all-round sweet spot – great for 1440p, enough immersion without a huge arm swing.
- 32 inch and ultrawide: more space for single-player and productivity; often too large for aim training.
Measure viewing distance: many people sit about 60–80 cm from a 24–27 inch screen.
2. Resolution
- Full HD (1920 × 1080): less GPU load, high FPS easier to hit – typical for esports 1080p.
- QHD / WQHD (2560 × 1440): sharper image on 27 inch; needs noticeably more graphics power.
- 4K (3840 × 2160): maximum detail, often pricier and more demanding – this guide focuses on 1080p/1440p.
3. Refresh rate (Hz)
More hertz means smoother motion if your GPU delivers enough frames:
- 144–165 Hz: solid step up from 60 Hz.
- 180–200 Hz: common on current midrange gaming monitors.
- 240 Hz+: mainly for very high, stable FPS in shooters.
Set the maximum refresh rate in Windows/GPU drivers – otherwise the monitor often stays at 60 Hz.
4. Panel type
- IPS / Fast IPS / Rapid IPS: good colours and viewing angles, widely used in gaming.
- VA: often higher contrast, sometimes different motion behaviour.
- OLED: very fast pixels and deep blacks – more expensive; follow manufacturer burn-in guidance.
Response times (GtG, MPRT) are manufacturer figures and not always comparable. Treat them as orientation, not the only buying criterion.
5. Adaptive Sync, HDR and connectors
- Adaptive Sync / FreeSync / G-SYNC Compatible: matches frame rate and Hz – less tearing.
- HDR / DisplayHDR: worthwhile mainly with a meaningful certification (e.g. DisplayHDR 400). Many “HDR Ready” models look subtler in practice.
- Connectors: DisplayPort often for the highest Hz/resolution on PC; HDMI for consoles. Check the manufacturer's table (e.g. 1440p@180 Hz only over DP).
Which monitor fits which setup?
- Valorant / CS2 (competitive): prefer 24–25 inch, Full HD, high Hz, IPS. More on ranks: Valorant ranks explained and CS2 ranks explained.
- All-round PC gaming: 27 inch QHD, 144–200 Hz, Adaptive Sync.
- Mixed gaming + work: height-adjustable stand or VESA arm, good text clarity.
- Matching peripherals: gaming mouse, headset, mouse pad.

Checklist before you buy
- 24–25″ (aim focus) or 27″ (all-round)?
- Can the GPU do 1080p or 1440p at your target FPS?
- Do you need height adjustment / VESA?
- DisplayPort planned for max Hz on PC?
- FreeSync or G-SYNC Compatible listed in the specs?
FAQ
Is 144 Hz still enough for competitive play?
Yes – the jump from 60 to 144 Hz is often bigger than from 144 to 240. What matters is that your FPS actually use the Hz.
24 or 27 inch for Valorant?
Many preferences sit at 24–25″ Full HD for sharpness and overview. 27″ QHD also works – taste and seating distance decide.
IPS or OLED?
IPS is the common middle ground. OLED offers different blacks and often very fast pixels; price and manufacturer burn-in notes matter.
Do I have to enable HDR?
Only if it looks sensible in that game/content. Many entry-level HDR modes look washed out – DisplayHDR 400 models are often more clearly specified than plain “HDR Ready”.
Which cables do I need?
For high Hz and resolution, usually DisplayPort 1.4 (PC). HDMI version and max Hz are in the manufacturer's table – not every HDMI cable/port delivers the maximum.
