So I have a 24 inch 1080p television and when I run 720p with it on Xbox it looks identical to 1080p, however when I plug in my laptop via HDMI and run 720p, it looks much worse. My PC can only handle games at 720p and it would be much better to run at that resolution!
How to I fix this?

I have an idea. I'm not sure if I'm right but there's an easy way to find out. It could be that for some reason your TV isn't recognizing the laptop as following the HDCP encryption standard.
A HDCP protected system consists of: 1) HDCP transmitter (DVD player for example), 2) the digital interface (DVI or HDMI), and 3) the HDCP receiver (your display monitor). In brief, the content is encrypted at the transmitter and the signal is passed to the HDCP receiver (display) via the DDC lines where it is decrypted before viewing. HDCP requires that both the transmitter and the receiver comply with standards. If either one does not comply, the video will not be displayed properly.
Analog signals do not adhere to this standard and so would be unaffected. If your laptop also has a VGA output and likewise the TV has a VGA input, you could try that and see if the picture improves. If it doesn't then I'm wrong and something else is going on.
