What to know before buying

Listing details to confirm

Listing details conflict or are inconsistently described: response time is given as 5 milliseconds and 1ms MPRT, brightness as 350 lux and 250, and the 99% color-gamut figure is not given a unit in the specifications despite a separate 99% sRGB claim. The model token also varies between C305B-200UN1 and C305B-200UN1T.1, and the form factor is listed as Square despite the ultrawide curved description. Confirm the exact revision and its specifications with the selected listing.
