Native 1080p television and 720p : why does it look so bad?

Hey everyone!

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?

Thanks!

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.

I appreciate the reply but I do not believe it is that complicated. It's just like running 720p on a native 1080p monitor except through HDMI, it looks worse because of the scaling. Since this is a television it shouldn't really matter as the Xbox scales perfectly to make 720p look exactly like 1080p. Would it be different because the Xbox is through component and the Laptop is through HDMI?

Laptop has a Nvidia GTS 360m by the way, should be compliant with all the standards.

According to your original post you were setting the TV to 720p, so no scaling is going on. Nothing is being resized. The only time the Xbox would even need to resize anything was if you were upconverting something to 1080i/p (or 720i/p), like when you pop a DVD in there (which if memory serves correctly is 480p).

And to answer your last question about the Xbox using component cables, yes. Component is analog as well. Again, if I'm right then that would explain why the Xbox looks better.

Just try it through VGA. If I'm wrong then you've only wasted all of 2 minutes.

EDIT

Actually, you could also try setting 1080p on the laptop and TV using the HDMI cable. If I'm right then it will still look like crap.
