Can I upgrade tv my to 3d, just with a 3d blue ray disc player?

Nope. U have to bought a 3dtv and 3d capable blu ray as well and might need for a 3d shutter glass. I suggest u go for Samsung TV's or LG TV's they got what it takes.

Actually, no. You would either have to have a 3D TV or a 3D-Ready TV. With the former, you have everything you need as far as the TV goes. To watch 3D content on it, you may get one of the 3D cable networks with your cable or satellite provider, and/or you can get a Blu-Ray 3D player. If you have a 3D-Ready TV, you can get an after-market kit to let you watch 3D TV. That comes with the active glasses and an emitter (transmitter) that connects to your TV.

u shouldn't get 3d it is overrated and pointless that techonolgy we readying had before only lately after some movies it became famous plus remember its not only the tv u also have to buy the expensive glasses plus 3d isint as good as u may think its not an opinion its an fact many tech critics agree

No, I think you need to purchase a 3d tv instead. Even if it was 3d ready, it won't have a 3d effect like the real 3d tvs.

tell me who wants to watch tv wearing weird glasses

nope, gotta have a 3D t.v. too
