IMartz verdict
Pros
- 4K 160 Hz and 1080p 320 Hz in one monitor.
- Very good factory calibration and strong SDR performance.
- Full-bandwidth HDMI 2.1, full PS5 compatibility
Things to consider
- HDR is limited by the IPS panel's lack of proper local dimming.
- Not the fastest IPS on the market.
- 1080p on a 32-inch screen loses a lot of sharpness.
A good fit if…
- Users who want 32 inches, 4K and a high refresh rate without premium pricing.
- Combining PC, PS5, productivity and multimedia on one monitor.
- Those who value Dual Mode to switch between 4K sharpness and 320 Hz fluidity.
Consider another option if…
- HDR is your absolute priority.
- You want the fastest possible IPS monitor for competitive gaming.
- Your system cannot handle 4K; in that case, look for a lower-resolution OLED
