32-inch 4K QD-OLED gaming monitor

This 32-inch display combines a 3840 x 2160 QD-OLED panel with a 240 Hz refresh rate and a 0.03 ms response time. It targets competitive gamers and creators who need high pixel density and fast motion clarity. The 16:9 aspect ratio and 178° viewing angles suit both desk setups and multi-monitor arrays.

Custom heatsink graphene film thermal management

A custom heatsink, graphene film and advanced airflow design work together to dissipate heat during normal operation. The monitor runs at 250 cd/m² typical brightness and 450 cd/m² maximum in SDR without active cooling noise. Power delivery over USB-C reaches 90 W while the panel maintains 99% DCI-P3 coverage and true 10-bit colour at Delta E < 2.

Sustained HDR load and burn-in mitigation

Under prolonged HDR workloads the panel can reach 1000 cd/m² peak brightness while the heatsink assembly keeps temperatures stable. An optional uniform brightness mode holds luminance steady across long sessions and OLED Care functions reduce static-image retention risk. The 1,500,000:1 contrast ratio and VESA DisplayHDR 400 True Black certification remain consistent throughout extended use.

Questions about this item

Will my graphics card drive 4K at 240 Hz on this monitor?

You need a GPU with DisplayPort 1.4 DSC or HDMI 2.1 that supports 3840 x 2160 at 240 Hz. Check your card's specification for that exact mode.

Can I charge a laptop through the USB-C port while gaming?

The USB-C port delivers up to 90 W Power Delivery, enough for many thin-and-light laptops. Verify your laptop's charging requirement before relying on it.

Does the heatsink and graphene film need any maintenance?

No user maintenance is required; the custom heatsink, graphene film and airflow design operate passively to manage heat and reduce burn-in risk.
