HD TV - anyone else think it just looks glassy and false?

Might just be that I've only seen display sets showing very contrasty animations etc but do folk really reckon HD is a quantum leap over a decent regular set up? Anyone invested and been disappointed?
HD is as great a transformation as as tape to CD, black and white to colour, VHS to DVD, and now DVD to Blu-Ray. Sadly most of the sets you see in Comet and the like are badly installed, they are not fed from a clean mains supply, there are transients on the power circuit caused by fork lift truck chargers and other office equipment etc. Normally they all share a common aerial feed so if you get a crap picture on one, you will probably get a crap picture on all of them. Mostly all the so-called Sales Experts do not even know how to set up a set correctly with a test card transmission, and that is why you see vivid colour with crazy contrasts - this is not how we see things, we see flesh tones and that is what you should see. If you see an orange which is really bright orange, almost glowing, sure it looks impressive and presents a sharp image but that's not how orange's look
What is also important is that the set has been callibrated correctly at the factory and often they are not. If its a projector, it should be done by an ISF accredited technician. The reason that test card transmissions used to be shown at the close of the broadcast every night, was not to bore the person watching the tv, but to allow you to adjust the greay scales correctly so that you have decent contrast, and to also allow an engineer to provide convergence if the geometry of the set was not correct. Nowadays the convergence has either been performed by computer at the factory or is not necessary on modern sets which project on the screen in a different manner. Either way, grey scales are important to set up.

No, you've been watching crap sets.
Personally, I'd say the exact oposite, the bigger the difference you can see between SD and HD then the crapper the set.Any old b
ks TV can show a decent HD image. A really good TV will also show a good SD image, so the better the TV the less difference between HD and SD - imoSubjectively speaking, HDTV is an enormous step up from PAL sets.
What was the content you were viewing ?
I remember once milling around Curries and looking at SkyHD sets, walked up to the demo and saw it was demonstrated using a 32in LCD screen, upon closer inspection the muppets used a composite video connector to connect the TV to the SkyHD, completely breaking the HD.

In a bizarre way I find HD a bit offputting - rather than actually watching some sort of film that you abstracted from I find that the details is sometimes so realistic that it takes the 'fantasy' out of the film. For example, I was watching one of the Narnia movies and rather than appearing like a fantasy world it became too obvious that this was just filmed in a field in NZ.
