Dual-mode OLED for competitive and immersive play

The 32-inch UltraGear OLED switches between 4K UHD at 240Hz and Full HD at 480Hz via a hotkey, letting one display serve both graphically rich adventures and high-speed esports titles. Adaptive sync works with both NVIDIA G-SYNC Compatible and AMD FreeSync Premium Pro for tear-free motion in either mode.

Who benefits and who should look elsewhere

Gamers who want a single monitor for story-driven 4K experiences and ultra-fast 480Hz competitive play will fit this panel. Users needing a curved ultrawide, built-in speakers, or a dedicated KVM switch should consider other models.

0.03ms GtG response time decides suitability

The near-instantaneous 0.03ms gray-to-gray response all but eliminates ghosting, making the panel viable for the fastest reflex shooters. If your workflow prioritises static text clarity over motion speed, a high-PPI IPS alternative may feel sharper for desktop use.

Questions about this item

Should I run the monitor at 4K 240Hz or Full HD 480Hz?

Use 3840 x 2160 at 240Hz for detail-rich games; switch to Full HD at 480Hz via the hotkey when you need maximum motion clarity in fast-paced titles.

What does the 0.03ms response time deliver in actual play?

The near-instantaneous pixel transition virtually eliminates ghosting and motion blur, so fast-moving objects stay sharp even at 480Hz.

What does DisplayPort 2.1 actually enable on this screen?

DisplayPort 2.1 provides the bandwidth needed to drive 4K at 240Hz or Full HD at 480Hz without compression or chroma subsampling.
