Headaches with HDTV?

[vlame]

how many hz is the tv going? we are all used to 60 but 120 and 240 are too fast and gave me a headache for awhile.

I can't see why a higher hertz rating would give headaches. If anything the less noticeable flicker the better.

However, I have seen HD LCDs response times tend to appear a little more pixelated compared to a similar HD CRT.

Different standards from different manufacturers. A further read.

In contrast to LCD displays, plasma televisions and CRT TVs have a virtually instantaneous response time.

This is mainly limited by the speed of their video processing engine rather than by the time it takes to fire the display phosphor; this is in the order of nano-seconds as against the milliseconds required for the liquid crystals to change state in LCD panels. In this respect, LCD panels still have a long way to go.

Yet, there is a further technical difference between the two technologies that renders plasma superior when it comes to pixel response time. Control of pixel intensity in a plasma display does not rely on the same drive process used in an LCD panel. In an LCD display, a minor adjustment in pixel intensity level is brought about by altering the drive signal in very small steps to adjust the twisting action of the liquid crystals, and which in turn controls the amount of light reaching the surface.
