This monitor does support DVI outputs.
It has great picture quality and for the price it presents a great size monitor.
The 26 is DVI(HDCP) while the 22 is a HDMI/1080P input/DTV tuner.
Unfortunately not, although this unit will process digital signals and HD signals from the computer the TV Tuner portion is NTSC-M, PAL-M/N, PAL-SECAM and in order to process digital TV signals in the USA the tuner must receive ATSC (digital) signals
