TV buying advice please

A question about : TV buying advice please

https://www.currys.co.uk/gbuk/tv-dvd-...pdt.html#cat-0

Am thinking of buying this. Right size, I like LG (I think) - good reputation ? Like 5 yr guarantee.

Some Qs though as I have never had a tv connected to a computer.

Does wifi mean that I do not have to have the computer on?
Does a hdmi lead need to connect the two, or is there no lead, ie Wifi (confused here.
IS this set 4 k (if not, what). 3 k then ? Presumably this is 'enough'
4k(this is the HD value ? - comes later this year ?

3d not particularly worth paying for in a TV as there are not many fils shown in 3d anyway... ?

What is 'smart' about this TV ?

Does HD cost any extra through Sky ?

I have a cracking tv at the moment. Big/cathode ray, but still working. The above though looks to be a 'bargain' ?

thanks - any help from u folks appreciated

Best answers:

• The TV isn't 4k, its a Full HD, or 1080p TV. 4K is 4 times the resolution, and alot more expensive. (most things arn't in 4k yet anyways)
  The wifi is used for internet access, this means the tv can connect to your wifi router (if you have one) to access the internet. This is used to update the tv when needed as well as for the smart tv functions.
  Most tv's dont come with leads, so you one need one that can connect your computer to the tv, if thats how you plan to use it. A hdmi cable should do the job if you computer has hdmi out, otherwise you may need something like DVI - HDMI, depending on what connections your computer has.
  Smart functions are where you can use apps to access various services online, things like BBC Player, and other catchup services.
  If you dont curently have Sky HD, then you might need to get a new sky box and upgrade to the HD package. You dont need Sky HD to use the TV thou, but it would be an improvement
• "Smart functions are where you can use apps to access various services online, things like BBC Player, and other catchup services."
  Already have this on Sky
  " new sky box and upgrade to the HD package".
  so this will cost me.
  "the tv can connect to your wifi router"
  i OBVIOUSLY HAVE A ROUTER THOUGH IT IS CONNECTED BY LEADS, SO NOT 'WIFI'. iF i HAD A WIRELESS ROUTER, i WOULD NOT NEED LEADS ?, IE WIFI IS A SIGNAL/NO LEADS ??
  Going off the idea !
• thanks for that.
  Router is a Sky SAGEM - does have 2 connections free
  Lookng at reviews, I see
  "no twin tuners - you cannot record one show while watching another"
  ??? how can this be if I am connected to Sky. Surely I CAN watch/record ? Are they talking about Freeview connected only ?
  The HD thing confuses me. Not all programes are in HD - true ?
  I must pay extra for Sky HD - true ? (then I will get all ?? progs in HD?)
  This set is not 4k (what is it then, 3k?), but if I was looking at one that was, 4k,, there would be no point in having 4k unless I had HD - true?
  The ability to get ALL progs in 3d IS appealing - would make up for no 4k I would think /
  Would you computer haveto be actually turned on to get a signal to the TV, or is plugging it into the router, enough ?
  All very confusing
• "In particular the dual play which allows 2 people to both view their own screen whilst gaming removing the need for split screens"
  How is this possible ?? I can see how with a split screen = 2 picturs, but how can 2 people see a different thing on the same/one screen ??
• blimey - didn't know that was possible. A good feature if there are 2 of you.
  Price comparisons for this are interesting.
  Went to PC world "last few going at Ј649 (with 5 yr g'tee".), Was Ј899.
  Everywhere else they are Ј649 ish all the time !!
• thank you all VERY much
