    My old man is looking to buy a 27' LCD. Has seen the Logik in Currys for £799.

    However where he wants to view the set via freeview the signal strength is not the best, will this have serious problems for viewing an LCD??

    Yes. If you have a bad video source, LCD is not for you.

    If he can pick up a satisfactory freeview signal and intends to watch by freeview, a LCD will be just fine. The quality of a freeview picture is not dependant on the quality of the signal, as long as you do not get dropouts. By this I mean, the picture remains solid throughout and does not suffer from unacceptable picture breakup. If he does get breakup, the picture quality is likely to be unacceptable no matter what screen technology and what size he is viewing. For the Logik that you mention, an external freeview tuner will be required. Some freeview tuners handle marginal signals better than others, so one box may give a good picture and another suffer breakup - a question for the freeview forum.

    If he can't get a satisfactory quality freeview signal, it depends on the quality of the picture he has now and the quality of the tuner and electronics in the TV that he intends to buy. A high resolution large screen, such as a LCD or some plasma's will highlight any problems in the source. Some screens will handle poorer quality signals better than others. High resolution screens have to create information based upon the information in the surrounding picture area. If the surrounding area contains unwanted noise, and this is not filtered by the electronics of the TV, then this noise will be magnified when creating the surrounding picture information. A standard TV picture generally contains 720x576 pieces of picture information and was designed to look acceptable at screen sizes of up to about 21". For LCD or other high resolution displays, this needs to be magnified up to 1280x768 or more, and look good at even larger picture sizes.

    It may well be true to an extent. However the OP mentioned watching Freeview. Freeview is a digital medium and as such never produces a bad video source. It produces either a perfectly good one, or an unwatchable one, or none. Unlike analog media which degrade gradually with reduced signal, digital media degrade suddenly and almost completely with reducing signal. So, for Freeview use, the argument you pose (whilst possibly accurate) has no validity.

    An LCD will produce excellent results if driven via RGB from Freeview, assuming Freeview itself is glitch free.
