Yes you can use the tv for your monitor and you can use the HDMI connection.
Thank you for the response! Okay. Now...I use HDMI? I'm a bit confused. Normally monitors have a blue plug in on the back, you plug it in and then you screw it in with attached thumbscrew type things. I don't use that but rather and HDMI cable? My TV supports both, it's labeled "HDMI IN" and "PC IN" so yeah just a little confused on the purpose of each one and which one I need.
