Just out of curiousity ... Has anyone out there seen the new Super Hi-Res mode on a monitor that actually supports the 1200+ pixels across? I have a 1950, and Super Hires on it displays every other pixel. The reason I am wondering is that there don't seem to be all 4096 colors in Super-Hi-Res mode on my 1950 ... If you try to change the color of, say, your background in the workbench using the pallete editor, there doesn't seem to be 4096 colors available for the background, more like 1000 or so ... So, is this just my ignorance and my monitor ;v) Or Does Super Hi-Res have some color restrictions? * saunders@triton.unm.edu * "This is _NOT_ Mel Torme!" - Top Secret

[...] The 1950 displays the Super Hi-Res mode just fine. You have to turn off the display enhancer, otherwise you get the "every other pixel" effect. Also, since Super Hi-Res uses 35ns pixels, only the restricted 64-color pallette is available. I would love to have a 1000+ pallette in Super Hi- Res, but the 64-color pallete isn't really as restrictive as I thought. ------------------------------------------------------------------------------- The DiskDoctor threatens the crew!

In SuperHires you only have 4 colors out of a palette of 64, I think. >So, is this just my ignorance and my monitor ;v) Or Does Super Hi-Res >have some color restrictions?

You must have the Display Enhancer turned on. In Super HiRes mode, the Display Enhancer only samples every other pixel, producing the results that you described. Turn the Display Enhancer off, and you will see everything. > >The reason I am wondering is that there don't seem to be all 4096 >colors in Super-Hi-Res mode on my 1950 ...

The Super HiRes mode has a lot more than "some" color restrictions!! In the Super HiRes and Productivity modes, the palette has been severely crunched from 4096 colors to 64. You are also unable to display more than 4 colors at once, out of this 64-color palette. > >* saunders@triton.unm.edu * "This is _NOT_ Mel Torme!" - Top Secret ------------------------------------------------------------- / Marc Barrett -MB- | BITNET: XGR39@ISUVAX.BITNET / / ISU COM S Student | Internet: XGR39@CCVAX.IASTATE.EDU / ------------------------------------------------------------ \ The great thing about standards is that / \ there are so many of them to choose from. / -------------------------------------------------------

Both modes are limited to 4 colors selected from a reduced 64 color palette.

I Guess to do with the bandwidth restriction that reduces the maximum number of bitplanes from 4 to 2, but why does this affect the depth of the colour palette (4bits to 2 bits per primary colour (R/G/B). thanks, Murray =================================================================================== Murray Gilbert s8922967@ipc01.mqcs.mq.oz.au ===================================================================================

Well, I have the switch enabled and I am using Seiko 1450. I run SuperHires Interlaced with NO flicker and it looks wonderful. What is the deal? Is it true that SuperHires *should* be flickered? Should I not be able to even see this 15Mhz graphics mode on my 31Mhz monitor? -Rich -- // Rich | "If I spent as much time on my classes as I do reading \X/ Andrews | news, I'd graduate." - Brett McCoy

Because you obviously don't read the manual! It says crystal clear, that this display enhancer can't work in this mode. Reason: the high pixel rate and lack of memory for so many pixel values. If you wanted it to do this also, then you would have to pay real $$$ more, because memory and other circuitry at double speed increases its price over- proportionally (sp?). You sure DON'T WANT to spend that price, if you are a standard Amiga user. Consider: This flicker fixer comes with every A3000 and has to be paid by every owner, even if he doesn't have a 30 MHz monitor. -- Best regards, Dr. Peter Kittel // E-Mail to \\ Only my personal opinions...

The Display Enhancer messes up the Super-HiRes mode when it removes the flicker. It only looks right when it flickers.

(BTW, this is on systems with Display Enhancers, >such as the A3000) I just installed my A2320 card, and am using it with a Mitsubishi Diamond Scan, but I don't have the ECS yet in my A2000. However, from what I read in the manual, I think Marc is on the wrong track; displaying SuperHiRes has nothing to do with flickering! What my manual tells me is that (not in so many words) because the A2320 (and presumably the equivalent circuitry in the A3000) has to buffer up a screen's worth of pixels, for either scan doubling or deinterlacing, that it doesn't have enough on-board RAM for the 1280 pixel lines (or maybe more correctly, that it can't sample that many pixels per line, which would explain why it skips every other pixel). Now, depending on what monitor a person has, they may not see much difference at that resolution (1280 is a *lot* of pixels per line). The words in the A2320 manual are: "Still another Amiga display mode which uses the ECS under AmigaDos 2.0 is 'Superhires' mode. This mode has a display of either 1280 x 200/256 or 1280 x 400/512, with 4 colors out of a palette of 64, and a raster rate of 15.734 KHz NTSC (15.625 KHz PAL). In this display mode the A2320 only samples every other pixel and may cause a distorted display, so you should set the mode switch on the back of the A2320 metal bracket to the Bypass mode (flip the toggle switch to the right, away from the fan)." Note that this has nothing to do with interlace; the same instructions apply to the interlaced AND non-interlaced versions of Super-HiRes. - Mike-- - Mike Shawaluk (oovvoo@mixcom.com) "It is a good day to live."
