What to know before buying

The viewing experience with the 800R curve can vary with viewing distance and posture. The monitor's OSD includes OLED protection settings, according to the manufacturer.

Listing details to confirm

Listing details are inconsistent or unconfirmed: resolution appears as 5120 x 2160 Pixels and separately as native 5118 x 2160, while the aspect ratio is listed as both 16:9 and 21:9. The item is described as WOLED in the title and feature copy but as OLED in the structured screen-type field. The 330Hz mode is specified as WFHD in one claim and described as a 1440p high-refresh option in customer feedback, with one customer reporting an issue. Confirm the relevant mode and exact configuration before buying. The listed 1300 candela_per_square_meter brightness is a peak claim, while manufacturer copy gives 275 nits at APL 100% and 1300 nits peak at APL 1.5%.

Customer feedback praises the panel's reported quality, desk appearance and curved shape, with one customer appreciating how the curve keeps screen areas at a similar viewing distance. Image quality and value are mixed: the crisp 5K2K image is appreciated, while one customer reports trouble with a high-refresh option and many describe the monitor as expensive. The reported mode concern is relevant because the listing distinguishes 5K2K at 165Hz from WFHD at 330Hz, and also contains conflicting descriptions of the higher-refresh resolution. Feedback offers a limited, mixed picture rather than a guarantee of results.

Positive themes

Customers praise the monitor's quality, appearance and screen curvature.

Mixed feedback

Image quality and value receive mixed feedback. One customer reports an issue with a high-refresh option, and many find the monitor expensive.
