Asus PQ321: Test 1 4K monitor public

Announced in June, the PQ321 is presented as the first 4K monitor marketed in mainstream distribution channels. A logical evolution in view of expected developments in the market for 4K TVs, but that does not have the same potential on a computer screen, with different uses and a diagonal of “only” 31.5 inches. We tested this monitor signed Asus, focusing on uses photo, video, game, office. Must pay nearly € 3,500 to move to 4K?
