I don't think it is FULL HD though.
The resolution of that TV 1366 X 768 (so the link above says).
The 768 is the number of lines on the screen (we don't see them of course but they are there).
Proper HD is 1080 lines, and you will of course get a much better picture with a TV that has 1080 lines than one that only has 768 lines.
So while Sky will be pushing out a signal of 1080 lines your TV will downscale it to 768 lines.
If you are going to pay out for Sky Q then I would seriously think of getting a TV that can handle 1080 lines (full HD). If you don't you are missing out on a lot of the quality.
I see the review for this TV was from 2011 so that is quite old in TV terms (and it was an inexpensive TV then) so I would go for a brand of TV that gets good reviews (Samsung, Panasonic etc) and supports 1080 lines.
Richer sounds are a good place to get quality TVs at a bargain price (they often pick up TVs that are at end of life, so the companies are trying to sell them off). But they are often less than a year old so they are very new TVs, just not the latest model.
