Need help switching to a new monitor on my PC

[pmarsh11]

So I have been working on this all day but no luck. So I had a sylvania tv as my monitor for my Lenovo k450. That tv was a piece of junk so the resolution was way down. I have a Vizio tv that works pretty well as a monitor so I decided to use that, so I put the resolution up to where it has to be to run the Vizio. But when I plug the HDMI into the Vizio, the Vizio just says "not support" yet it still works on the sylvania. I think my main question is how to make the Vizio "screen 1"

the vizio says "not supported"? what is the model# of the vizio as I now think it is a settings issue in the vizio as it worked before?

It's a Vizio E240AR

This will work for now until I get a monitor though, so thank you so much for the advice I was helpless!
