    Hi all,

    First of all my wishes for great 2012 to all of you :thumbsup:

    Now, I have been using Plasma screens since the first day, mostly the high end of Panasonic, for the moment I have a 50" VT20.

    Since a moment this set is giving me some trouble and I would like to replace it with a LED screen but I don't have the slightest knowledge of LED technology.
    Why LED, screen burn in (I do get it with gaming), better design (WAF) and less power consumption as the screen can sometimes run for over 12H during the weekends while gaming.

    What do I need to look for in a LED TV? Backlid, Edge, ... How many Hz, etc ...

    I'm not looking for specs that will allow me to use a PS3 with minimum lag and a Mac Mini HTPC. Most probably I'll go for a Sony to match other Sony gear.

    Many thanks ;-)

    Hi there

    What's up with your VT20? I had a Panasonic V20 that had fluctuating brightness issues, flicker, bad posterisation, loud buzzing and the 50hz bug of course. Coupled with the fact that I see phosphor trailing really easily plus whites on screen always looked too dull, I gave up on the V20 and went to a Sony LED. Best thing I ever did, I would (after my expensive waste of time with a Panasonic plasma never ever go back!)

    Anyhow, what's your budget?

    As you'll probably know, you can still get traditional backlit LCD sets as well as edge lit LED sets and full array (full LED backlit sets). The most commonest in retailers at present is edge lit LED. Not necessarily the best sets in some cases (they are more prone to backlight issue's like bleed and clouding)...However, the consumer driven market for "thin = better" has won through and these sets, as I say, are what you will see most of within the LED/LCD range of sets at present.

    I have (after 2 x faulty Sony EX723's) a Sony NX723 46". I must say, it's a fantastic set, HD and SD are brilliant. SD in fact, on some higher bit-rate freeview channels can almost look HD to me at times (I did say "almost"!!!)

    However, depends if you are after the 3D element, which I know with the EX723 and NX723, is rated as poor (plus you don't get the glasses with the set). Mind you, I couldn't give a monkeys about 3D, I just wanted a decent 2D TV - which I have, at last, found!

    As I say, what is your budget?

    Hi,

    Thanks for the info :)

    My VT20 has mostly issues with screen burn, severe even such that it doesn't go away even after playing a 2H movie.

    I was indeed also looking at the Sony NX series, somewhere between 40" and 55". My budget is rather flexible but not more then what I usually pay for a new set, so top 3000£.

    3D is a "nice to have" but certainly not a "Must Have", I consider it a gadget that will be used once a year, I used mine once in 2y and by the second time the batteries of the glasses were empty and I couldn't be bothered to change them :D
    The thing with 3D is that most of the high end sets all include 3D by default.

    I just want the good tech inside so that I can have the best image possible for movies and games, sound is not important either as it will all be played through my HC, as for gadgets such as internet TV they're in the same leave as 3D, "Nice to Have" but no deal breakers.

    Oh, one thing I might keep as an important option is controllability through iPad, I do would like to be able to use an iPad App as Remote, but that's for a personal project I'm working on. ;-)

    Funny you should say that about the ipad remote function - I set up only yesterday my new ipod touch with the Sony Remote App - works quite well and also means that you can use the phones keyboard for web entry on the tv - although the web browser itself isn't really up to much on these TV's...doesn't support Flash etc...so sometimes a bit of a waste of time, but hey ho!

    3D is a complete and utter "no no" for me. Zero interest! I *might* be interested in future, when more and more material is available in 3D AND when the time comes when you don't need glasses (!) - but at present, I personally couldn't care less. Hence, whilst these (EX and NX) sets do get generally bad reviews for 3D, this wasn't even taken into account when I chose my current set.

    The EX and NX are essentially the same set (the 723's I am referring to here) - it's just the NX has the "nicer" look, with the gorilla glass fronted screen and built in wi-fi, rather than relying on a wi-fi dongle as you do on the EX723.

    The internet content on these TV's are brilliant - iplayer works really, really well in HD, music channels/Channel 5 On Demand, You Tube (HD clips look very good indeed sometimes!)....

    Just bear in mind that with edge lit LED sets, you will often end up with ones that display banding/clouding etc... It's sadly a little bit of a lottery when it comes to edge lit LED screens (not just Sony, I am speaking broadly across the board here).... I had 2 x EX723's (brand new) which both suffered from excessive clouding. Eventually, after a long wait, just a week ago, got a NX723 (46") as a replacement. As I said earlier, essentially the same panel and tv as the EX723 - just with the glass front and built in wi-fi really..

    Luckily this set does not really suffer at all from clouding or banding - so for me it was a case of third time lucky! But I am really pleased with this TV now. As I mentioned earlier, SD looks fantastic on it - overall a very nice tv....

    Hi,

    Again many thanks for the feedback, truly appreciated !

    I'll have a look at both the EX and NX series then :)

    On the Sony site they mention a difference in LED technology, one is edge and the other one is local dimming, should I care about that difference?

    As for 3D, I'm in the same boat as you, it's a gadget, if it's there then I'll most probably try it out but I will not choose a set based on 3D availability.

    Web surfing won't be an issue either as I'll use the Mac Mini for it in the lounge and otherwise the iPad or MBP.

    As you'll notice, I attempt to manage everything through Apple devices, music and movie collection are in iTunes and streamed to the ATV2's, iPad's or iPhone's over the house, so having Sony Apps is a true plus to have it all managed the same way.

    Again, thanks for the feedback and I'll pop over to the Sony Center to have a look at the 40" or 46" NX series, I'll probably stick to NX as the design will have a higher WAF factor ;-)

    No worries, yeah, have a look in the Sony Centre and see what you think. NOT that I recommend you buy from them (!) but I know Curry's have an online web price of £899.00 on both the EX723 and NX723 46". This is a really good price. The only reason I can think of that you might just opt for the EX723 is if you are placing the set opposite a big window, hence have lots of bright reflections (the EX of course having the matte screen). Mind you, even with a matte screen, it's surprising how much light these can reflect.

    The EX and NX are both edge lit. It's just that the NX has "LED Dynamic Control" within the menu which relates to local dimming - to be honest, I wouldn't really worry about that feature too much - I have ALL the picture processing modes turned off all the time anyhow, as I think often they can prove detrimental to the image.

    Perhaps, if you are visiting the Sony Centre and you see an NX (and EX723 come to that) it might be worth playing about with the brightness control on dark screens to see if you notice any clouding - it will be immediately obvious if you do, the brighter the screen goes, the more you see it. I only really mention this, because *if* you saw one that didn't display any banding/bleed/clouding despite ramping the brightness up (I know you wouldn't do this at home re brightness, but just saying to do this instore to try and check for clouding) then it *might* be worth asking how long on display that set has been and perhaps consider taking the display model (providing it looks good and is in perfect condition of course PLUS not been on display for months on end!)...... I would never usually EVER recommend this (display models!) BUT - after having 2 x faulty sets (EX723's) it was the only way in my small Sony Specialist Dealer store that I could guarantee getting a decent panel! Might be worth thinking about!
