Landing Runway 26 Using Visual approach guidance from GTN 650(Garmin Navigation/Display). No glideslope guidance was provided by the GTN. I crossed what appeared to be the threshold with very faded marking in significant turbulence. I taxied to the ramp without incident. Only after reviewing the track log from foreflight on google earth did I realize I may have actually landed on the displaced threshold. I believe better markings on the displaced threshold would help prevent this in the future. In addition; a more positive identification of runway markings on my part and a go around would have prevented this event. Contributing was a runway change from our planned arrival to Runway 35R due to changing winds.
A pilot reported they landed on the displaced threshold due to insufficient runway markings at HDO airport.
