Make sure you at least do a rough calibration on your TV sets and computer screens, there is free software around to at least get it setup vaguely right.
Moth3r is right though, a few of the transfers in the past have had crushed blacks and whites, which makes an image look 'punchier' but blows out the detail in the shadow areas and bright areas - no matter what you view them on.
Also the softer and more processed the image, the worse it will look on larger screens.
When looking at the stills try to look at the tonality range in the images, is there definition and detail in the bright white areas, is there detail in the dark shadowy areas?
Then look at small detailed parts of the images, can you see the intricate detail where it should be, or has it been 'smoothed over' and so on.
At first glance a crushed and smoothed picture may look "better", but on closer inspection you may realise that it is too soft and lacking in detail.
I haven't looked at the farsight set in any detail, but I did notice the crushed whites when I watched ANH on my TV.
