Pros and cons

Pros

Dual modes accommodate buyers who prioritize 4K detail or very high refresh at Full HD, subject to compatible graphics hardware.
OLED, listed 4K resolution and a 1,500,000:1 contrast ratio support a sharp, high-contrast gaming picture.
Adaptive-sync support is listed for both G-SYNC Compatible and FreeSync Premium Pro.
The described stand adjustments and matte surface provide useful setup flexibility and reflection reduction.

Cons

The 480Hz mode is Full HD rather than 4K, so buyers must trade resolution for the higher listed refresh rate.
The listed 275 cd brightness may be a consideration for buyers seeking a bright display. Customer feedback also describes brightness as mixed.

What to know before buying

Listing details to confirm

The listing is inconsistent about the display technology field: its title and display-type detail identify OLED, while the technical display-technology field says 4K UHD. The listing separately describes 4K at up to 240Hz and Full HD at up to 480Hz, and its USB port fields do not fully specify port functions. Check the selected configuration and connection requirements, including graphics-card support for the desired resolution and refresh rate. Peak brightness is stated as up to 1300 nits in feature copy, while the details field lists 275 cd.
