ATI Radeon HD 4000 Series discussion

Those are hdtv's. I don't think you can get an actual 120fps in computer games with those, can you?

For example, most movie projectors advance from one frame to the next 24 times each second. But each frame is illuminated twice or three times before the next frame is projected using a shutter in front of its lamp. As a result, the movie projector runs at 24 frames per second, but has a 48 or 72 Hz refresh rate.

When LCD shutter glasses are used for stereo displays, the effective refresh rate is halved, because each eye needs a separate picture. For this reason, it is usually recommended to use a display capable of at least 120 Hz, but 200 Hz is optimal. Unfortunately most monitors cannot handle this rate, especially at higher resolutions.

While common multisync CRT computer monitors have been capable of running at even multiples of 24 Hz since the early '90s, recent "120Hz" LCD displays have been produced for the purpose of having smoother, more fluid motion. As 120 is an even mutiple of 24, it is possible to present a 24frame/s sequence without Judder on a well-designed 120 Hz display. If the 120 Hz rate is produced by frame-doubling a 60frame/s 3:2 pulldown signal, the uneven motion could still be visible.

120Hz =! 120 FPS. That means that the monitor will be refreshed at a double rate and the only visible benefit you will see will be when you go the mirror and see that your eyes are still healthy after hours using the computer.

So even if they launch a 240Hz means 4 x 60 = 2 x 120 = 240Hz.

a movie in a movie theater is what 24 fps

It depends it varies to 24 to 30 frames per second, with this monitor they can create movies at 60 FPS.
