Not Ideal For
🗂️ Extreme Multitaskers 16:9 Only
Standard 16:9 cannot fit two full-width apps without overlap. An ultrawide replaces a dual-monitor setup cleanly.
💻 Single-Cable Laptop Users No USB-C
No USB-C port means separate video and power cables are needed for a laptop. No single-cable docking possible.
💡 Quick Advice: Buy this for competitive gaming at 240Hz. Buy this if speed is your priority. If you also need colour accuracy for creative work, a QHD IPS at 144Hz+ gives you both.
