Need help from tv bods

[PaulRotheram]

Well I've not got a clue about tvs, I currently have a 22 inch goodmans tv in my room, got freeview and hd tv but the view point does my head in as if I'm sitting too low or high the picture looks dark, especially annoying playin games when on dark levels.

Now I'm after a bigger tv, looking at a 32" and found this:
LG 32" LCD TV 32LD320

LG 32" LCD TV 32LD320
32 Inch LCD HD Ready TV
Digital Freeview
Energy saving with intelligent sensor
Picture wizard
Clear 2 Voice technology
Invisible speakers
ISF certification
Cinema mode
Game mode
Sports mode
2 HDMI inputs
Resolution 1366 x 768
Contrast ratio 3,00,000:1
Dimensions (without stand) (mm) 805 x 528 x 79.9
60,000 Hour life span
Anti-dazzling eye care
Aspect ratio correction - 8 modes

Now I've no idea what the above means, but the tv retails at 299 but is on offer at a shop near me for one day only at 179.
Any ideas if this would be a good purchase?
I'd appreciate some honest advice as I'd farther wait and have something I'll enjoy rather than do my head in like the current one I have.

Forgot to add, I'm and avid xbox live user, and watch films quite frequently if that makes any difference for what I need.
