Four factors really matter for CS2:

  1. Refresh rate class: 144 Hz is enough for beginners, 240 Hz is the sweet spot, 360 Hz is premium, 540 Hz is esports-only luxury. The biggest jump you feel is 144 → 240.
  2. Motion clarity (= response time and strobing): Helps you hit moving enemies. OLED < 0.1 ms is top, TN with DyAc⁺ just behind, IPS lags clearly. "1 ms IPS" is mostly marketing — really 4-5 ms.
  3. Resolution vs. GPU load: 1080p any GPU can do at 400+ FPS in CS2. 1440p needs an RTX 4060+ for 360+ FPS. 4K is pointless for CS2 — eats FPS without competitive advantage.
  4. Size: 24-25" is standard for 1080p, 27" for 1440p. At 32"+ you no longer see your peripheral FOV — bad for CS2.

What does not factor into our rating: HDR marketing claims, RGB lighting, frame sync (FreeSync/G-Sync are standard today). Refresh rate and response time are the only values that make a measurable difference for Counter-Strike.
