The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Date has passed, but hexus.net does not confirm it happened then; unverified.
Computerworld's own headline, "Dell to ship first 32-inch 8K display, the UltraSharp 32 Ultra HD," matches the pin's claim, though the fetched page returned unrelated content and no stored publish date, so the exact date could not be independently confirmed.
GSMArena reports the $5,000 UP3218K carried "a shipment date of April 17," with the article itself published 24 March 2017 - matching the pin's stored date as when the listing went live for preorder, even though actual shipping trailed into April.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
