What to know before buying

Listing details to confirm

Listing details are inconsistent: the resolution field calls the display “5K UHD 2880p”, while separate native and maximum-resolution fields state 5120x2880. Brightness is listed as 750 Candela per Square Meter in specifications but feature copy claims a 1250-nit peak. The 5K 165Hz and QHD 330Hz modes are stated in feature text, while the general refresh field says 165 Hz. Check the intended configuration and claims against the selected listing.

Who is it for?

A good fit for

Gamers who want a high-resolution 5K mode and a separate higher-refresh QHD mode.
Desktop users who value a high pixel count for detailed on-screen text and images.
Setups that can use a USB-C connection for display, data and the claimed device charging.

Less suited to

Buyers who require 330Hz while retaining 5K resolution. The listed 330Hz mode is QHD.
Buyers who need a settled brightness figure before purchase, as the listing gives conflicting values.

Aggregate ratings are mixed, with a substantial share in the four- and five-star categories and a smaller two-star share. The sample is small and no customer comments are supplied, so it does not show what prompted the lower ratings or establish how the monitor performs in use. Buyers should weigh that limited feedback alongside the listed 5K and QHD dual modes and the specification discrepancies.

Frequently asked questions

What resolutions and refresh rates are listed?

The listing describes 5120×2880 at 165Hz and 2560×1440 at 330Hz. The higher refresh rate is paired with QHD, not 5K.

Is the monitor’s listed resolution consistent throughout the page?

No. A resolution field says “5K UHD 2880p”, while separate native and maximum-resolution fields give 5120x2880. The listing also gives conflicting brightness figures, so confirm these details before buying.

What is claimed for USB-C?

Feature text claims USB-C supports display output, data transfer and up to 90W device charging. The technical details also list USB Type C connectivity.
