With the damn of the A2320 card, many people thought products like MicroWay's flickerfixer were no longer needed. I have an idea that perhaps some enterprising company may want to produce someday. The ECS Denise provides 2 new interlaced modes, 640x960 and 1280x400. The Display Enhancer on the A3000 nor the 2320 deinterlaces these( probably slow/not enough ram on the card for sampling). So is it feasibly possible to de-interlace these modes, and will any monitor support it?

Technically, this type of card would be possible, but would cost at least twice as much as the current de-interlacer/scan-doubler type of devices today. The real problem is that instead of outputing 28Mhz pixels, such as these devices do today, the version 2 card would be outputing about 57Mhz pixel data. You would have to buy a very expensive monitor that has a video bandwidth that high so that you could resolve these pixels on the display!! So, instead of spending about $700 - $900 dollors for say the A2320 and A1950 monitor, you would have to spend about $1600 for this new display device and appropiate monitor. Not what I would call a high-volume or even a cost-effective solution! But then again, some third-party developer may feel He/She has a market for such a device - go for it!

My eyes aren't very good, but whenever I see an a3000 (or a video toaster ad on tv), the screen still has JITTER problems!!

What you probably see is the bouncing problems of the original 1950 monitors.. As for the toaster ad, NTSC jitters as a matter of specification. I find all computer generated graphics/animations on NTSC to display this effect, whether the were generated on a Chiron 5 Character Generator or a Pixar or IRIS. I even notice jitter and motion aliasing on live video from a camera. Also, you should know better than to throw tidbits like, "or a video toaster ad on tv". Now you're gonna have to tell us ALL about it. :-) >Phil Dietz > > >-- Subliminal Signature > Phil Dietz > A M I G A 231b3678@fergvax.unl.edu > Univ. of Nebraska -- Colin DeWolfe dewolfe@ug.cs.dal.ca

I wonder if this is the solution to the problem that Amiga Unix faces when placed next to the Sun Workstations. The biggest complaint that I have heard thus far about the 3000UX is that you can't hook up a mega-pixel 19" monitor that is color. Is there a better approach to this problem?? > > Regards, > Scott Hood > > -- > -- > Scott Hood, Hardware Design Engineer (A3000 Crew), Commodore-Amiga, Inc. > {uunet|pyramid|rutgers}!cbmvax!hood hood@cbmvax.cbm.commodore.com > "The views expressed here are not necessarily those of my employer!" -mark= +--------+ ================================================== | \/ | Mark D.

It's as simple as that. Don't generalize your problem to all A3000s, it's just not true. -- Ethan "It seemed like he appeared on every television show except Wheel of Fortune.

If you purchase the A2410 Hi-res graphics board which our UNIX can talk to, provides a display of up to 1024x1024 with 256 on-screen colors out of a palette of 16.8 million and with a 50Mhz TI34010 graphics processor. These board will be available from Commodore in the near future. I have seen these running on our A3000UX machines with Xwindows and it looks great!! These systems love to be hooked up to a 19" color monitor as well!
