27" Dell UltraSharp U2721DE gaming monitor performance benchmarks

Dell U2721DE er en forholdsvis ny skærm. Med hensyn til pixeldensitet har Dell U2721DE en fremragende tæthed på 109 pixel pr. Tomme, hvilket resulterer i skarpere tekst og billedkvalitet. Monitorpanelet har gode synsvinkler og giver bedre kontrast og farver end TN-paneler. For grafikfarvekvalitet har Dell U2721DE en fremragende farvedybde på 8 -bit, hvilket resulterer i glattere gradienter og mere præcise farver. Dell U2721DE har displayporten, og det er vigtigt for NVIDIA-kort at arbejde med AMD FreeSync. Skærmen har en VESA mount. Lysstyrken på Dell U2721DE er lavere end andre skærme. Den mindste svarsfrekvens for Dell U2721DE er 7.7 ms, som kan forårsage spøgelsesvirkninger. Dell U2721DE har et samlet input lag på 28.7 ms, hvilket er dårlig blandt konkurrencen. Uden AMD FreeSync-understøttelsen er denne skærm ikke kompatibel med AMD-grafikkort. Dell U2721DE har en maksimal opdateringshastighed på 60 Hz, og dette kan være for lavt til de ekstremt hurtige billedfrekvenser i konkurrencedygtige spil. Grafisk krævende spil kan forårsage rammefald uden for den adative opdateringshastighed på 60 Hz. Skærmen har et unimpressivt kontrastforhold på 1014 : 1. For den gennemsnitlige responstidshastighed er Dell U2721DE scorerne 19.2 ms, som kan forårsage bevægelsessvøring på grund af ineffektiv synkronisering med den høje opdateringshastighed.
