How do I fix my xbox's resolution stuck in 640 x 480

After I unplugged and moved my xbox one and the same tv I have been using it with for months, the resolution became stuck in 640x480 and I'm not sure how to fix it because thats the only option it gives me when I go to display options. Everything was fine beforehand and nothing serious was changed. I have unplugged it and left it off for 60 seconds, reset my console and tried using a different hdmi cord in case that would work but nothing has it resolved.
