Acer Predator XB323QK V4 — 31.5" 4K UHD IPS at 160Hz
4K UHD · 160HzHDMI 2.1 at 160Hz95% DCI-P3 · FreeSync PremiumHeight · swivel · pivot
The Acer Predator XB323QK V4 is a 31.5-inch 4K UHD (3840 x 2160) IPS gaming monitor with a 160Hz refresh rate and 0.5ms minimum response time, for players and creators who want 4K detail on a large screen with smooth high-refresh motion.
At 31.5 inches, 4K gives about 140 PPI: very sharp text and game detail with enough room to use Windows at 125–150% scaling. Both HDMI 2.1 ports run at 160Hz, so current consoles and a PC can share it, and 95% DCI-P3 colour suits photo and video work too.
Before you order: 4K at high frame rates needs a powerful graphics card. The monitor has no USB-C input and no USB hub, and adaptive sync is AMD FreeSync Premium (no G-SYNC certification published).

Frequently Asked Questions
Will PS5 run 4K at 120Hz on this?
The HDMI 2.1 inputs accept 4K high-refresh signals; the console then runs at its own supported rates.
What graphics card do I need?
For 4K above 100 fps in modern games, a high-end card; esports titles run fast on mid-range cards.
Does it have USB-C for my laptop?
No. Use HDMI or DisplayPort from the laptop.
Singular Expert Insight · Buyer's Guide
The XB323QK V4 is a big-screen 4K monitor that does not force a choice between sharpness and smooth motion, and its HDMI 2.1 support makes it console-friendly. Plan the rest of the system around it: GPU power and a separate USB hub if you need one. Compare more sizes in our
PC monitor range.
✓ Buy it if you want a large 4K IPS screen at 160Hz for PC and console gaming plus photo or video work.
✕ Skip it if you need USB-C docking, certified G-SYNC or bright HDR.
→ Also consider the ASUS ROG Strix OLED XG27AQDMESZ for OLED contrast at 1440p.
