This is from the API Guide and works well for us - on Tizen 2.4 and above screens

 var connectedVideoSources;
 function successCB(source, type) {
     console.log("setSource() is successfully done. source name = " + source.name + ", source port number = " + source.number);
 }

 function errorCB(error) {
     console.log("setSource() is failed. Error name = "+ error.name + ", Error message = " + error.message);
 }

 function systemInfoSuccessCB(videoSource) {
     connectedVideoSources = videoSource.connected;
     for (var i = 0; i < connectedVideoSources.length; i++) {
         console.log("--------------- Source " + i + " ---------------");
         console.log("type = " + connectedVideoSources[i].type);
         console.log("number = " + connectedVideoSources[i].number);
         if (connectedVideoSources[i].type === "HDMI") {
             // set HDMI as input source of the TV window
             tizen.tvwindow.setSource(connectedVideoSources[i], successCB, errorCB);
             break;
         }
     }
 }

 function systemInfoErrorCB(error) {
     console.log("getPropertyValue(VIDEOSOURCE) is failed. Error name = "+ error.name + ", Error message = " + error.message);
 }

 try {
     tizen.systeminfo.getPropertyValue("VIDEOSOURCE", systemInfoSuccessCB, systemInfoErrorCB);
 } catch (error) {
     console.log("Error name = "+ error.name + ", Error message = " + error.message);
 }

I have used the same code but the code is not working from tizen.tvwindow.setSource(connectedVideoSources[i], successCB, errorCB);
