Finally bit the HD bullet after 15 years thinking I was very happy with my Sony Trinitrons. I read up endlessly on review websites until I decided it must be worth giving the 42" LG plasma PW450T a go, since after all, it scored 9/10 from users for picture quality and that was all I was interested in, not the 3D or Smart TV bells and whistles, just a crisp sharp picture for watching sport, news and nature/documentary progs.
The LG panel looks very smart and was easy to put together on its stand, and yes, the HD picture is pretty good when hooked up to a Sky HD box especially if you have never before watched HD at home.
However, be warned. Many of your favourite channels may be broadcast only in SD (standard definition) - BBC2, BBC3, BBC4, BBC News24, More4, any +1 channels etc, so buying a HD set can turn out to be a step backwards if it cannot handle SD channels well. This is called upscaling apparently and depends on the sophistication of the screen's circuitry. Clearly with a budget 3D set like this (and you are getting a big heavy beast of a plasma TV for just £400) corners must have been cut somewhere and it isn't just in the set being 720 lines HD Ready rather than the full HD 1028p resolution. SD channels are generally reproduced in a poor way, too often with jagged blurred and sparkly outlines (compared to the crisp sharp outlines produced by this set in HD), depending to an extent on the quality of the original programme broadcast.
Of course, even on an expensive high end HD set, SD channels will seem relatively soft in outline compared to the pin sharp image of HD broadasts, but believe me, you get what you pay for (as I'll explain in a second) and the LG 42PW450T just did not cut it with SD programmes. This was especially noticeable watching any channels with text banners on like BBC News24, Bloomberg, CNBC and such like. But it was not just the text, the presenters faces kept disappearing into a smudge of blurred pixels every time they moved.
As a result I just could not watch this TV after 48hrs of giving it my best shot so had to email the retailer to register a return within the 7 days allowed under Distance Selling regulations.
Worth noting as well that the screen is HIGHLY reflective compared to more expensive sets which use filters to subdue reflections on the glass and unless you are in a very dark room, reflections from furniture, lights etc will interfere with the clarity of the image even when watching HD broadcasts.
Also, I do not believe the review I read that most people will not be able to tell the difference between 720 HD Ready and 1028p full HD. I certainly could, once I had swapped the LG for a full works HD Sony.
One last point, the LG set is a nightmare to try and set up with the contrast/brightness/colour balance that you prefer. The pre-sets are soooo very different for standard tv, film, sport etc (sport was unwatchable with luminous green grass) and the menus to tweak them go on for ever. I found myself wanting to fiddle and try and improve the colour or brightness every time I changed channel.
I came to the conclusion that rather than be constantly irritated by the shortcomings of the LG set, I ought to spend enough to try and guarantee a quality picture in both SD and HD. After all, I might be watching this set for the next 15 years. So being a Sony devotee for the previous 30 years and despite some reviews suggesting Sony is now being overtaken by the likes of Samsung in HD technology (I find Samsung sets aesthetically just a little too 'bling'), I plumped for the Sony 40" HX723 LED panel, which with a 200hz frame refresh rate should have enough frame speed to handle sport well without blur or drag.
OK, it cost 50% more than the LG plasma (although with a fine S380 Sony Blu-ray player included in the package), yet it seemed to be the minimum spend to get an LED set that would handle fast moving sport well and process both SD and HD content in an impressive way.
The difference is chalk and cheese.
The Sony handles everything thrown at it (including sport) with aplomb and HD is stunning. The 'out of the box' picture settings are also much better than the LG set and the menus to tweak changes much simpler. Screen reflection is not an issue and SD channels are brilliant - sharp images, rich colours and deep blacks. Its biggest shortcoming is inevitably the sound which can lack depth due to the shallow panel/speakers, though with 30W it is not as thin and tinny as you might expect, certainly for general TV viewing. I have hooked up my hi-fi amp and speakers to boost the sound when watching films.
So don't be put off by an LED panel if you want to watch sport in HD. It doesn't have to be a plasma and a cheap plasma can too easily be a false economy.
