A. Generally nowadays with all the 12ms, 8ms and below panels being used, ghosting is just not an issue. Choosing a TFT should really be based on looks, price and any extra features you might need. The fast response rates of the panels used now are perfectly adequate to cut out pretty much all obvious ghosting and blurring, even in fast paced games.
Generally it is considered that a response time of 25ms or less should be fine for gaming in most cases. Panels with 16ms, 12ms and 8ms are now common and ghosting has become even less of a problem. The new breed of 4ms and below panels should hopefully help even more, and the concentration on grey to grey transitions has helped improve pixel latency even more.
There are a few commonly used panels in the 17" market. These include the 16ms AU Optronics and LG Phillips panels, and the 12ms Samsung and AU Optronics panel. Users of all these panels have said they are fine for fast paced games inc. Quake, UT2003, Half Life 2 and other popular FPS. Remember, different manufacturers have different ways to measure the response rates, so one company’s 16ms panel may not be the same as another company’s 16ms panel. The ISO norm for quoted response time is the black to white transition. This was traditionally the fastest transition, but thanks to Overdrive technology, manufacturers have managed to improve the grey to grey transitions more. Look out for response times quoted as G2G instead.
Ghosting may also depend on how susceptible you are to things like this, as one person may see no ghosting, another may see lots on the same panel. The best bet is to try and see a TFT in action in a shop and see for yourself, if that’s not possible you will have to settle for the opinions of other users on here and take the plunge!
