I was doing a little bit of modifications to my VIM, and my HTPC the other day,
ATI 1650 analogue output to my Marquee,

Here is what 1080p at 100hz and 120hz looks like :eek:

This is just for giggles, enjoy

Steve, are you able to do a close up of the desktop icons at those frequencies?

Looks nice and fuzzy in the corners...

I had to down-rez the pics, so pic is softer,

But I don't have any close-ups of the icons.



I will hook up the pc again in a couple of days and post some more pics.


Cheers
Steve


I do have this though

I always thought the internal menues will be clear no matter the frequency settings?

Athanasios

I'm far from an expert, but my guess is that internal menus will be clear-ER but not 'clear'. The internal menus are scanning at the same frequency as the rest of the screen, obviously, so if the ability of the PJ to *scan* is causing problems, that'll show in the menus. But if it's loss in the signal chain or processing, you won't see it there; only in the 'real' display.

Has anybody tried shutter glasses with a PJ running at 100+hz? I know a lot of them are used just that way in academia / sims, and given that my Barco 808s doesn't show much flicker at all at 60hz (whereas it's horrific on a regular monitor) it might work quite nicely..

At 100Hz the pixel clock should be somewhere near 260MHz. The video chain, ideally, would be capable of passing square waves at 130MHz.

At 130Hz pixel clock should be about 320MHz and video circuits, once again ideally, should pass square waves at 160MHz.

Ummm Ummm :eek: what does that mean? Square waves?

Athanasios

Nashou, think white-pixel-black-pixel-white-pixel-black-pixel. The height of the wave is the brightness.

So when the wave gets rounded off in *time*, the output gets smoothed out in *space* as the wave is 'painted' along the raster.

You can think of the pixel clock as a bunch of pixels streaming single-file down a pipe at a certain rate.

(This is rough; I know just enough about CRTs to be dangerous.)

You want the transitions between pixels to happen as quick as possible. The longer it takes the more "gray" there is in between the pixels which means less sharp.

Scott

Not really sure what this thread is about, because what would running 1080P @ 100hz be proven? It way beyond anything we watch, to include exceeding the best of CRT resolutions.

I've tried it on my 8500, but the card will only go up to 85hz. This is no where near being resolved:

Get it up to 600hz so we can have judder-free 24, 25, 50, and 60 hz video!
