Mitsubishi Intros 120 Hz Interpolated Full HD Monitor
Mitsubishi's latest display boast of an industry first in double-speed interpolation, a technique of combining 60 Hz images for a more fluid 120 Hz output. The RDT232WM-Z which carries this feature, is a 23-inch TN panel monitor with 1920 x 1080 pixels resolution, 3 ms response time, 1000:1 contrast ratio, 3W stereo speakers, and inputs which include DVI, D-Sub, and HDMI as display connectivity. It will be available in the Japanese market from June 11.

i found things saying my samsung does the exact same thing (120Hz panel, but only 60Hz inputs so it doubles internally)
Anyways, providing a remote for a bigger monitor is a nice touch. More companies should do it.
We already have TV's that only accept 60Hz and interpolate to 120Hz/240Hz. Having that on a PC screen is more or less useless for anything but bargaining rights and watching certain movies. It's a technique that might reduce ghosting and add to sharpness, but increases everyone's favourite "input lag" too.
What's wrong with the real thing?

My PS2 still looks like crap on it though.
Watching 60Hz video however, will look nice and smooth, because of the interpolation from 60 to 120.
On a 120Hz, each frame is repeated 5 times and playback of the non-native format is smoother. That's why 120 and 240hz TVs don't have the 24 frame jitter.
Still, if it can output 120hz, why not just accept 120hz inputs?

But as I said, if it outputs 120Hz, it should just accept 120hz input as well. Doesn't make sense to accept only 60hz input on a 120hz computer monitor.
If you have your output set to 60hz while watching a movie, you will get jitters, as they are already in the signal going to the monitor. If you set your output to 24hz, like the standard setting on a BD player, you don't get jitters.
Although, I think we are talking about 2 different things here.
Here in the UK, we use a 50Hz/fps PAL video system. A 24fps film is played back at 25fps, which results in every frame being shown twice. This leads to very visible judder and looks very unpleasant. Some TVs have the frame interpolation function, making the film motion look smooth like on 50Hz video. Because the TV has to guess how the inbetween frames should look, frame interpolation works to varying degrees of success and can easily cause its own artifacts.
Also, I happen to be able to prove this at home. My DVR can play back smoothly at double speed (without sound). Do that with film and the judder disappears completely, as it's being shown only once. The motion is silky smooth and has no unpleasant artifacts.
Why they still insist on using cruddy old 24 or 25fps film for modern made-for-TV productions beats me. :banghead: +1
there is a very big difference between running at 24Hz, and running at 60Hz with a 24FPS image.
most common situation 24 - 60 - 60 - 60
what this monitor would be most likely doing 24 - 60 - 60 - 120
what Wile E think his monitors are doing 24 - 24 - 60 - 60
what 120hz 24p TVs are doing 24 - 24 -120 - 120
Again, a 24fps movie played on a 60hz display jitters because of pulldown. It plays one frame 3 times, then the next frame 2 times. It's this uneven amount of frame repeats that causes the jitter. 120hz screens repeat all frames the same amount of times.
Pal is completely unrelated to this discussion.
Playing your DVR at double speed does not prove your point. It is also a completely unrelated phenomenon.
