KTMJ's earlier purchase by New Vision Television led to their replacement by locally based newscasts produced by its NBC-affiliated sister station KSNT. On October 12, 2010, WDAF-TV became the fourth (and last) television station in the Kansas City market to begin broadcasting its local newscasts in high definition. On April 11, 2011, the station extended its existing pre-Fox-era late newscast, with the debut of a separate 10:30 p.m. news program on Sunday through Friday nights (Fox late night programming airs on Saturdays during that half-hour); as a result, it became the first Fox station – and one of only a handful of television stations in the Central and Mountain time zones – to expand its 10:00 p.m. newscast to a full hour, a format more common in that timeslot with prime time newscasts aired on Fox stations and non-major-network outlets in the Eastern and Pacific Time Zones.

The station shut down its analog signal, over VHF channel 4, on June 12, 2009, at 9:01 a.m., the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. WDAF continued to transmit its digital signal on its pre-transition UHF channel 34. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 4.
