I was wondering if anybody can help me with a couple of questions please,
I've just brought a philips aquos 32" hd tv/monitor which I'm using for my desktop but the highest resolution on it is 1360x768 which makes everything huge on the desktop, I was wondering if hdmi cables increase the resolution/pixels
its got 2 ports for hdmi and I wanted to use them both.
the secound question is does one end of the hdmi cable plug into the usb port of the computer,
thank you:)

If your Computer doesn't have HDMI, You will need to use the DB Connector most likely.

...my desktop...the highest resolution on it is 1360x768
Upgrading the computer's video adapter to a model commensurate with your TV's capabilities will allow higher resolutions and possibly native HDMI connectivity.

...i was wondering if hdmi cables increase the resolution/pixels...
Nope, standard cables transmit signal, nothing more.

...does one end of the hdmi cable plug into the usb port of the computer...
No, do not do this.

Without a video adapter upgrade, depending on the connections your TV and current computer have, the most likely scenario is using the computer's HD15 D shaped video connector as suggested above with a HD15-to-Composite breakout cable and connecting to composite ports on the TV. The computer could also have a DVI connector and a DVI-to-HMDI adapter be used. These adapter cables can probably be found locally at an electronics store or by Googling online for a vendor (such as CablesToGo.com (http://www.cablestogo.com)).
