I read where someone else had a similar question, someone replied with using the external screen projection thing, which I found, but then said to choose the TV option which would confuse your xbox into thinking it was a TV, my problem is I cant find the TV option, can anyone help me?
Which model of Xbox are you wanting to connect?
If it is the Xbox One and you have Windows 10, you can stream video from the console to PC using the Windows 10 Xbox One app. The following link provides step-by-step instructions along with system and network requirements http/
*I'm not sure as to why the link shortens itself, but it directs to official Xbox support
On the Xbox itself, you'll need to manually enable game streaming. Then, using the app there will be an option to scan for the Xbox. Once found, you'll be able to connect and stream games so long as you are within range of the Xbox and requirements are met.
For older models of Xbox, I don't think you can stream nor hard-line connect video. But I am not fully certain of that.
