4K Resolution That Delivers Clarity and Detail
The 3840 x 2160 resolution on a 27-inch panel yields a stunning pixel density (~163 PPI), delivering crisp textures and razor-sharp UI elements. This is especially beneficial for:
- Next-gen console players looking to play games in native 4K at up to 120Hz.
- Content creators and photo editors who want sharp image reproduction and high accuracy.
- Multitaskers who need space for multiple windows or side-by-side applications.
The XB273K isn’t just about resolution—it’s about clarity without compromise.
160Hz Refresh Rate + 0.5ms Response Time = Gaming Nirvana
While many 4K monitors cap out at 60Hz or 120Hz, the Predator XB273K pushes to 144Hz natively and 160Hz with overclocking, giving it a substantial edge for competitive gaming in high-fidelity environments.
The inclusion of Visual Response Boost (VRB) brings the response time down to as low as 0.5ms, virtually eliminating ghosting during fast-paced gameplay. This is crucial for:
- FPS games like Call of Duty or CS2.
- High-speed racing titles like Forza Motorsport.
- Competitive MOBAs and battle royales where every frame counts.
Rich Color & HDR for Stunning Visuals
- 95% DCI-P3 color gamut ensures wide, vibrant color reproduction for cinematic visuals.
- Factory calibration out of the box means most users won’t need to fine-tune settings.
- VESA DisplayHDR 400 certification gives a modest but noticeable boost in contrast and brightness for supported games and content.
While not on par with true HDR1000 panels, DisplayHDR 400 offers solid entry-level HDR performance—especially for the price.
G-SYNC & FreeSync Support – No Tearing, Just Smooth Gaming
The XB273K V3 supports both AMD FreeSync Premium and is G-SYNC Compatible, covering both major GPU manufacturers. This dual compatibility ensures:
- Smooth, tear-free visuals across a wide range of frame rates.
- Great performance on both NVIDIA and AMD systems.
- Better gameplay stability during framerate dips.
HDMI 2.1 & Comprehensive I/O for Console and PC Setups
Key ports include:
- 2 x HDMI 2.1 – Crucial for PlayStation 5 and Xbox Series X to run 4K/120Hz content.
- 1 x DisplayPort 1.4 – Best for full 4K + 160Hz experience on PC.
- 4 x USB 3.0 ports – Great for accessories or peripherals.
- 3.5mm headphone jack – Convenient access for wired headsets.
This makes the XB273K ideal for hybrid gaming stations where you’re switching between console and PC setups.
Ergonomics & Build – Designed for Long Sessions
The monitor comes with a fully adjustable stand (tilt, swivel, height, and pivot), giving users the flexibility to find the most comfortable setup. The ZeroFrame design (ultra-thin bezels) adds a sleek look, especially in multi-monitor setups.
Some units even feature ambient RGB lighting on the rear, enhancing your battle station’s aesthetics without being distracting.
Considerations Before Buying
While this monitor has a lot going for it, keep the following in mind:
| Factor | Consideration |
|---|---|
| Heat Output | Some users report noticeable warmth during extended use. |
| HDR Limitations | DisplayHDR 400 is the minimum tier—good, not great. |
| Powerful GPU Required | To run 4K at 120Hz+ in modern games, you’ll need at least an RTX 4070 Ti or RX 7900 XT. |
| Price Variability | Although MSRP dropped to around $399–$499, prices can spike based on demand or regional availability. |
Overall: Still One of the Best 4K Gaming Monitors You Can Buy
