Vancouver Full Audioholic Oct 17, 2004 373 0 18 Vancouver, B.C., Canada Feb 17, 2005 #1 Does anyone know if they are currently watching video at 72Hz instead of 60 Hz? I am asking becuase it seems that this is source of the video effect I have been after. It creates jitter free movement and almost eliminates stress on a sub-conscious level while watching. How do you know if your TV is able to play video at that frequency? Can a fixed pixel display like a plasma do it?

That setting applies to CRT systems. As a rule of thumb with computer monitors, the higher you can set your refresh the better. It reduces eye strain. Your eyes can see 60Hz and under.

Vancouver Full Audioholic Oct 17, 2004 373 0 18 Vancouver, B.C., Canada Feb 17, 2005 #3 I am going to be using an external scaller that can send a frequency out at 72 Hz. my manual says that via PC input it can display some of the following: 1,025x768 @85 -----Horizontal Frequencey 68.68Hz---verticle frequence at 85Hz. Is that good? There are 21 different signals to choose from via PC input and since I am getting a scaler that can customize the output I am trying to decide which is best.

The higher your refresh rate is, the easier on your eyes it will be (assuming that the display you're using can handle it). 85Hz is dandy. Assuming your video display can handle that resolution, then it should be fine.

"24 Hz film-source material using a 3:2 pulldown pattern can be output with 2:2 pulldown at 48 Hz or 3:3 pulldown at 72 Hz."

W W9TR Audiophyte Feb 19, 2005 4 0 0 Feb 19, 2005 #6 I am currently watching at 72 Hz (71.92) using an HTPC and a CRT projector. If you have an LCD or DLP projector, the panel will be internally driven at a fixed rate, usually 60 Hz, and the projector's internal scaler will do the conversion. If you are using an external scaler, you should set it up to drive your projetor at its native resolution and frame rate.

I know Pioneer has some models available that do 3:3. Everything should be done that way... 72Hz/3 = 24 fps

Mustange steve...i think that infact the CRT is better when it comes to this. While my Plasma says it can accept 72hz or even 85hz the judder seems to get worse at those levels, which leads me to believe that it is accepting the higher rater, but then converting it back to 60.

The INPUT is not what matters, it is the output that the screen actually produces that should be your primary concern. If your display outputs exactly 1024x768 @ 60hz, then that is exactly what you should feed it with your DVDO. CRT is still the cats nipples as far as display devices go and other technologies are still playing catch up.
