I think it is a problem of TV type rather than a problem of size
A trusted well-known TV manufacturer (Sony,Samsung, Panasonic, LG.. etc) will never make a bigger TV unless it has the same quality of ordinary sizes, or even better.
And of course, i have witness many big TVs that lack the efficiency for favor of size, and you can bit that those TVs are not from above mentioned corporations.
Wanna a supreme big TV? LG is a very good one, but i always hear that Panasonic and Samsung TVs are better regarding non-3D TVs
(if you want a 3D TV, LG is an excellent choice)
And LCD & LCD LED TVs are not the only choices, Panasonic plasma TVs always get high recommendations.. they provide high visual quality with 600Hz and high colour saturation & depth, even better than many LCD TVs from other famous manufacturers (but this on expense of TV expectant life and energy consumption)
This is my non-professional opinion.. I am currently searching for a resonable sized 3D TV, so the recommendations i have just typed was collected or given for me from here and there.
So you should wait for an expert opinion.. mean while determine your price limit, search Samsung, Panasonic, Sony , LG websites for a good TV that meets your limit.. write down models of your concern and compare between them technically, or better ask the help of someone that tried them... that what i have done.
Hope that helped & good luck
I have a 37 inch LG 1080p TV in my bedroom. I bought an Insignia LCD 55" 1080p, 120Hz, for the living room.
The picture on the Insignia is great. But I can't believe the amount of shadowing I see when watching a program. If someone just get's up from a chair you can see the shadowing (or whatever you call it). I don't see this type of shadowing on the LG 1080p LCD 37".
So my question is this. Is the shadowing effect more noticable on a larger TV? If not, than this must be a poor TV and I will have to return it and buy something better.
Any comments appreciated.
