Every HDTV I have ever used has problems like this. It annoys the hell out of me. It seems to me that very few TV makers actually want (or think of the possibility of) people hooking up compters via HDMI. No matter how I set the settings for my video card or TV, I can NEVER achieve 1:1 pixels over HDMI, although VGA almost always works on the TVs that actually have it.

Your tv supports all hdmi, if you xbox works on it, then your computer can too with the right settings.

Op: It's not sending your tv the right signal , it's not fully your tv's fault, it's just crappy drivers having trouble with hdmi/hdcp as opposed to vga which always works you need to play round with the control panel abit more, create some custom resoltions/refresh rates and match them exactly to your tv unfortunatly (i've had this problem many times with cheap tv's) for your brand of tv it maybe hard to find out exactly the right scan type/polarity and sync width of pixels etc.
Nethertheless somewhere in your contlol panel you will be able to create custom resolution with of these above settings (or similar - i have nvidia here).
Also you can download rivatuner and get even more customization with that.

My manual clearly states it can't and so I tried it anyway. Looks like crazy, lol.

Hmm so I was right? Lol, gonna try HDMI to DVI adapter and hopefully that works. (Through shipping takes usually 3 weeks from oversea =/)

Lol trust me I tried that, and still can't seem to get it to work properly. Tried all sorts of crazy resolutions, but no go. I will give rivatuner a go and see if it will fix my issue.

I know how you feel, in fact I believe inside my TV manual it even stated that you have downgrading quality issues with a computer connected. o.O
