In the competitive world of esports, every millisecond counts. The difference between victory and defeat can be a single frame, a flick shot that was a fraction of a second too slow. Recognizing this, HKC has launched a display designed specifically for players who demand the absolute maximum performance: the UG25EF 420Hz Fast TN Gaming Monitor. Priced at an aggressive ¥1,999, this monitor is set to redefine the entry point for top-tier competitive gaming.
The Need for Speed: 420Hz Refresh Rate
Let’s cut straight to the headline feature: the blistering 420Hz refresh rate (achieved via overclock). For the uninitiated, refresh rate is the number of times your monitor updates with new images per second. While 144Hz was once the gold standard and 240Hz became the serious gamer’s choice, 420Hz pushes into a new realm of fluidity.
This ultra-high refresh rate drastically reduces motion blur and screen tearing, making fast-paced movements and quick flicks look incredibly smooth. For professional-level players in titles like *Counter-Strike 2*, Valorant, or Call of Duty: Warzone, this translates to a tangible advantage—seeing your target a fraction of a second sooner can be the key to winning a crucial duel.

Why the “Fast TN” Panel is a Strength
Some users might see “TN” and think of poor viewing angles and washed-out colors compared to modern IPS panels. However, for pure, unadulterated speed, TN technology still holds the crown. HKC’s “Fast TN” panel is optimized for this very purpose, delivering the incredibly fast 0.5ms Gray-to-Gray (GTG) response time needed to eliminate ghosting entirely.
Furthermore, HKC has addressed the traditional weakness of TN panels by boasting a 96% DCI-P3 color gamut. This means you’re not sacrificing all color vibrancy for speed; the UG25EF promises a much more vivid and engaging visual experience than the TN panels of old, all while maintaining its lightning-fast performance.

The HKC UG25EF has a very clear target audience:
- Aspiring and Professional Esports Athletes: If your livelihood or passion depends on having the most responsive hardware, the 420Hz refresh rate and 0.5ms response are your best friends.
- Hardcore FPS Gamers: Anyone who takes competitive shooters seriously will benefit from the buttery-smooth gameplay and crisp motion clarity.
- Gamers on a Budget Seeking Top-Tier Performance: At ¥1,999, the UG25EF makes an extreme refresh rate previously reserved for much more expensive monitors accessible to a wider audience.
