would like to know if any one has a 4k tv and do you like it 
 
thanks
 

RJ is right that there is very little actual 4K content right now.  The only two sources I know of are Sony's 4K box which only works with Sony's 4K TV's and Netflix is experimenting with 4K content.  Not to mention that they are already working on 8K.

I agree.  Not worth it at the moment.  You can find a very nice LED with a great refresh rate for a good price these days.  I would stay away from Plasma due to having to white/color wash once a week.

while 4k is not readily available from your cable company it is available from sony (which owns alot of movie and TV holdings http://en.wikipedia.org/wiki/Sony_Pictures_Entertainment ) there player is 699.00 but it is intended to be used with a sony 4k tv. i have watched a few movies in 4k and all i can say is wow. 

Not saying anything bad about LG but you can take a cheap Seiki 4K set and a quality 720P set is going to look better. Unless you are going to be buying a big tv and want to be an early adopter for hype and love spending money, don't bother. You are looking at a 49" tv; there are literally 100s of examples where, unless you are sitting right in front of it, you will not see a difference. Normally, I would agree and say to get a plasma but since no one is hardly producing them anymore, that's a big risk. I am slightly bias since I had a Panasonic Plasma and it crapped out shortly after warranty. While I agree that the newer 4k tvs will have some better features and some better advancements in technology, that doesn't necessarily translate to better picture quality. Most of the 4k panels are still utilizing a light source that is inherently not uniform. Local dimming, edge lit and all these other "tricks" are great band aids but it is still a flawed design. While I have some slight reservations about the graph below, it is pretty much spot on. People go to best buy or where-ever and go right up to a 4k tv and get "wowed" but in real life, you aren't going to have your couch 3 feet away with cranked settings and perfect source material.                                        Here is a cool calculator that even allows you to modify your eyes and shows how much benefit you gain from changing screen size. A little easier to understand than the graph for some people...

I could argue the opposite but there are tons of variables that could contribute each way. Sony used to make some great sets back in the day, they just started uping their game again so it's hard to say. I've seen some crap 1080P sets from Sony a few years but if you are comparing apples to apples, a person with 20/20 vision is only going to differentiate pixel density and detail only so much at so far away.
Not saying that the 4k tv you saw wasn't better than the 1080p for you or for anyone else but what I am saying is that the math doesn't lie, the picture quality was effected by things other than the panels resolution. One golf ball is going to look the same as 2 golf balls grouped together a few hundred feet up in a helicopter.

I have a 50" Panasonic Plasma 1080 and I have no problems with it. Purchased 3 years ago. Minimal input delay with my NES and N64. Not as fast as CRT, but I haven't found an LED or LCD that comes this close.
They do run hotter and use more electricity, but is a wonderful display.

OLED is the next "greatest" display. Unfortunately the price is too high at the moment.

 I hope yours keeps running. Mine hit the 3 year mark and the panel crapped out. Panasonic wouldn't budge to help me. They are good looking displays. If I could pick a perfect setup, it would be OLED but I think we have a while before they can do a big Oled display for a decent price. I would love a 4K 3d LED/laser based front projector with over 2500 Lumens when they can do that for less than 5 grand.

I just recently purchased a Samsung 60" H7150 and I love it.  With all the video inputs calibrated, it has a very nice picture quality.  I was considering the 4K TV sets as well, but the price was out of my reach.  The 4K sets from Sony and Samsung are nice too, it is like the 1080 revolution all over again, expect in 4K. 

That is a great tv but it will be awhile before 4k is common. Just look at blu ray sales for 2013... they are being dwarfed by streaming services. For a 4k signal  (compressed and @24fps) you would need a connection speed of 41MB/s  and uncompressed would be just under 700MB/s. My math could be wrong but I think a T3 line is 43MB/s.... and I think I remember reading that a normal full length movie would be in the neighborhood of 40gigs a movie if downloaded. So unless they can do some super compresson trick (which kinda defeats the purpose) or they start making 10 terabyte hard drives for cheaps, I don't see it as a viable option yet. As far as disks go, look how much a blu ray costs compared to a standard dvd. I can't see people spending 50     bucks for a movie especially the crap hollywood has been rehashing latley. Thats just my 8 cents. Unless your mom just loves spending money, I'd say go for a bigger 1080p or wait. If you want cutting edge, your wallet is going to bleed.

Dang, missed out on the event.  Will keep an eye out for future promotions.

they gave it a bad review but after  the firmware up date  they said it fix a lot of stuff and now they gave it a good review
 
 

Just get the sharp 8k tv that was at the CES this year. That way you will have a tv that is 8 times better!  Maybe they will make it with a 880 refresh rate and add 4d to it so you can smell the content too!
