@ 32inches for a desk space use I find 1080p is not adaquite.
TVs are behind in color quality as well, But if you think it will work for you go for it. Its just not something I would ever care to do.

The k90 is sorta mechanical, its all mechanical but the programable keys, and I think the 9 key.

If you go to even a walmart (the one around here has it) they might have a black widow for you to try. Or look at a best buy.
