I think Sony’s are too colorful – when I got mine I did so as someone online had calibrated it and I could get into the system menu and change the grey levels appropriately – it is still a bit too colorful.
My old Sharp LCD had a much better balance and things therefore look more realistic.
Don’t get a screen that is too big for your viewing distance or you will see all the mpeg type nasties and upscaling artifacts.
People used to like Plasmas over LCDS for picture quality for ages when the res on those plasmas was 480p – because they had no need to upscale.
My Sharp was a 540P panel, so for PAL is just dropped 12 lines from the top and bottom of the picture and mapped it straight on, for 1080i it also mapped straight onto the panel, and for 720P and 1080P it had too much info for the panel, so downscaled.
It took me ages with the new Sony to get the picture quality as good, with the Sharp being fed through SCART and a TopField PVR and the Sony being fed through HDMI from a Virgin V+ box which has 2 300 MIP processors doing the upscaling. When fed HD through HDMI it is very difficult to tell the difference between the Sony and the Sharp.
The only problem with the Sharp was feeding a PC into it as the res was a bit low, so I sold it to my mate.
Not all TVs across a manufacturers range are universally good – my Sony was good but the 40 inch version had shocking ghosting and in my view was not fit for sale.
I always get extended warranties on Sony gear as well – whereas I would be happier getting a Panasonic with a standard warranty.
