Plasma Display 600Hz on PC? How does this work?

I'd think it would have to support a 120 Hz input for 3D, but I don't see that as a feature for the TV. Also don't know if PC hardware is compatible @ 120 Hz by default.

Most any PC would be capable of 120Hz over Dual Link DVI or VGA. If the monitor will accept 120Hz from a PC is the real question.
3d compatible TV's still need only support 48Hz or 60Hz input for movies and tv. Movies and TV programming typically run at 24 - 30 FPS. Unfortunately, it is prolly better to assume it does not support 120Hz input until someone proves, or the mfg says, otherwise.

Actually, they are only required by HDMI 1.4 to support frame packing 3D format at either 720p50 and 1080p24 or 720p60 and 1080p24. But yes, 120hz input isn't required.

Thanks for the correction. I incorrectly thought they had just gone the 48 and 60 fps alternating frame route.
 
Plasmas using subfield technology split individual frames from 60hz input into pulses of light; these can vary in duration and have different hold times in order to produce a given luminance of a pixel element. It's very similar to the way PWM is used in backlighting (240hz for example) to modulate brightness. Only by doing this on a plasma display, you greatly reduce the motion blur in a wait-and-hold type device and generate all the thousands of grayscale shades required by varying the pulses of light (brightness) per frame.
 
I know the input is still only 60Hz, but is the actual refresh rate on those 600Hz plasmas the same as with 100Hz/120Hz ones?

The reason why I'm asking this is, I'm considering upgrading to a bigger plasma but the flicker kind of worries me. When I set my Panny to 50Hz it flickers like mad. At 100Hz it is much better of course but it's still about the same as using a CRT monitor at 75Hz - usable and not really noticeable aside from in very bright scenes. I could live with that much flicker but seeing as I'm upgrading to a quite bigger TV I'm guessing the flicker will be more noticeable. So is the refresh rate on these new plasmas actually any better or it's just all interpolation stuff?

Plasmas for the most part do not use interpolation, everything is 60hz or multiples of 24 for 24p content(48,72,96hz). Plasmas don't need motion interpolation for video content like LCDs do because they actually flicker much like CRTs whereas LCDs "sample and hold" a frame which is one of the big reasons people perceive them as blurry.

Film content and motion interpolation is just wrong from a videophile point of view so 5:5, 4:4 or 3:3 pulldown is used to eliminate film jutter depending on the brand.

Plasmas that support higher than 60hz do not exist, there are certain LCD monitors that do but not TVs that I know of. If you are inputting something like 100hz to your plasma I guarantee that only 60hz is being dislayed. 50hz = PAL or the Euro standard, so it's gonna flicker for sure on 60hz content.

In conclusion a good plasma is still better for motion than a true 120hz LCD monitor.. unless you see phosphor trailing but that's another story.

Yeah, I know I can't input anything more than 60Hz to the plasma. I was talking about regular TV stations (50Hz PAL). There is a refresh rate option on the TV which when set to 100Hz definitely improves the flicker dramatically by, I'm guessing, doing something similar to what 100Hz CRT TV sets used to do. The difference is like night and day but I can still see the flicker and it kind of worries me it will bother me on a bigger TV.
 
Is this a Panasonic TV? I know european Panasonic models use frame interpolation but here in North America our models don't have it. 100hz in PAL land = 120hz here so it sounds like it. The flicker you are talking about, is it during gaming, movies or TV?

With all this said a 600hz field subdrive does NOT = better motion. Plasmas have been using this technique for years and recently started including it in specs to best the 120hz (or 100hz in Europe) specs on motion interpolated LCDs.

Yeah, it's a Panasonic plasma.

I can see the flicker at any setting really, but watching 50Hz material with the 100Hz refresh rate setting turned on shows by far the least amount of it. If 600Hz doesn't really mean anything in terms of refresh rate/flicker then I will rather stay with a 42" TV than have to go the LCD route then. Thanks.
