- USB-C input with power delivery for laptop users
- Better motion clarity than Dell Alienware AW2725QF in Wirecutter testing
- Versatile for both gaming and work use
Cons
- Premium price puts it out of reach for budget buyers

Our take
If you want the best 4K gaming monitor and don't want to second-guess yourself, this is it. Every major source points here, and Reddit's no-budget thread calls it out by name.
Wirecutter doesn't pick flashy — they pick practical. The KTC M27P6 wins their top 4K gaming slot because it actually beats pricier rivals like the Alienware AW2725QF on motion clarity.
