Ok people, I've posted this once before and got (what I thought) was a straight answer. Now I have been reading about people who have been 'using their NEC 3D with their display enhancer perfectly' and this is driving me batty. I own a NEC 3D and I WANT a display enhancer but I would like to know if ANYONE has encountered ANY problems AT ALL using the NEC 3D in conjunction with the A2320 display enhancer. Help! -Joe Muller P.S. Please POST all replies here, since our feed has been kind of shaky.

Help! > > -Joe Muller > >P.S. Please POST all replies here, since our feed has been kind of shaky. I have an Amiga 3000 and a NEC MultiSync 3D. The 3D hooked up perfectly and it displays perfectly. The thing that I really like about the NEC 3D is that I can adjust the width and height of the screen to my liking and eliminate the visibility of the "flicker bug" on the first horizontal row of the display. While I am here, let me also say that I think that the NEC 3D is the (one of) the best monitors you could use with the display enhancer. I have been very pleased with it, and have absolutely no complaints. I previously owned a Commodore 19xx (whatever it was) that really really sucked. I traded it for a Optiquest (non-flickering at 1024x768) monitor that was supposed to be better than the MultiSync 3D (but it did not have width/height adjustment available in the 31 Khz mode!!!). Yes! Definitely get your flicker fixer, and never buy a Commodore MultiSync monitor, unless you are a glutton for self-punishment. I hope I offended the right people at Commodore, but I wouldn't expect to be so lucky. I was really pissed about the lacking of quality with those damned monitors. - Aaron Hightower

Although I do not own a display-enhancer or Nec 3D, I do remember something from a technical post a few weeks (months?) ago about a problem with some early copies of the display-enhancer. Something about a resistor on the board of the wrong value. This could be what has (?) caused problems in the past. > > -Joe Muller > >P.S.

The A2320 puts out a de-interlaced signal which is runing at approx 30Hz (I don't have the number in front of me). The NEC 3D can definately handle that speed. So if you want to look at the deinterlaced output (from your A2320) on your NEC 3D it will work fine. However, the A2320 has a switch to go back to normal interlaced output and for that switch to work your monitor has to support a speed of like 15Hz. Many Multi-Syncs will not support that slow of a speed, I believe that the NEC 3D (along with the A1950) is one of the only "Multi-Sync" monitors that will go that slow. So you will even be able to do that with your 3D, the only time you would want to would be if you were using the ECS SuperHires mode which the A2320 does not support (no current de-interlacer does). If all you want is the deinterlaced output (30 Hz) then you can even use a VGA style monitor. You just won't be able to turn your A2320 off like you can with an A1950. Once again I stress there isn't much reason to want to turn it off. The one disapointing thing about the Nec 3D is that it has a slightly larger scan area than the A1950 and unlike the A1950, you can't adjust the horizontal and verticle size of the picture. What this means is that on the A1950 I can adjust the picture to fill the entire monitor, while on the NEC 3D I will have black borders around the whole picture. A side effect of the Amber chip that the A3000 and A2320 use to de-interlace is that the first 1/2 of the top scanline still flickers, on a properly adjusted A1950 this can't be seen, but on a NEC 3D you will see it. No big deal... The comment about an incorrect resistor has nothing to do with an A2320 working on an NEC 3D. That refers to a bug on the A2320 which caused two levels of grey (777 and 888) to appear the same in the de-interlaced mode, the addition of a $.01 resistor corrects this situation and any authorized service center should be able to take care of it.

In addition, on my 3000, under 2.0, preferences doesn't allow me to adjust the overscan to use all of the area that the monitor is using; so the usable area is reduced even more. This seems to be a limitation of WB 2.0, not the NEC 3d.

Yes the horizontal and vertical size and position are both adjustable. I seem to have one small snag though. The Enhanced-Deinterlacer won't give me a picture that I can centre on the sceen when using overscan. I can adjust the overscan to reach the lefthand edge of the sceen, but the righthand edge of the picture won't go any closer than about 1.5 cm from the edge of the sceen, the rest is left in the background colour, unusable. The result is my picture is offcentre ( nearer the lefthandside). I can centrallize it by reducing the lefthand overscan. But that reduces the size of my picture.( the monitor ajustment can't make it any bigger). I suspect the this has something to do with the enhancer-deinterlacer, not the monitor. Interestingly, if I switch to PAL mode instead of Multisync mode I get a larger picture, and I can centre it. Has anyone else noticed this, or know why the multisync picture is so different from the PAL picture.( why is it smaller? why isn't it centred?) Andrew Chalmers Digital Communications Group (D.C.G.)

Yes I have noticed it. No I don't know why :( Probably something to do with the fact that Productivity pushes those chips way out on the performance curve :) >Andrew Chalmers David Navas navas@cory.berkeley.edu 2.0 :: "You can't have your cake and eat it too."

The Overscan Editor tool can do it from software somehow. According to it, PAL is Enhancer-off and Muktisync is Enhancer-on.

Nah, don't do that... The Enhancer is automatically turned off while in MultiSync modes. You'll want to leave it on in PAL -- should look a lot better, less flickery that way. Or am I misunderstanding you? >The Overscan Editor tool can do it from software somehow. According to it, >PAL is Enhancer-off and Muktisync is Enhancer-on. Or at least that's >the way it comes up on my machine What software were you using to get this info? I don't see this in my release -- but I have the advantage of being a developer and getting upgrades to WB releases :) Anyway -- for multisync, you don't need to disable the Enhancer, because it disables itself. For PAL you want the Enhancer *ON* to eliminate flicker in interlace modes. In multisync I can't seem to move the screen to the far right -- but then the multisync uses the right portion of the screen to increase it's vertical resolution to x480, instead of x400 [for 60Hz]. That's my best guess at the moment. -Dave > >> >>> Has anyone else noticed this, or know why the multisync picture is so >>>different from the PAL picture.( why is it smaller? why isn't it centred?) >> >> Yes I have noticed it. >> No I don't know why :( Probably something to do with the fact that >> Productivity pushes those chips way out on the performance curve :) >> >>>Andrew Chalmers >> >> David Navas navas@cory.berkeley.edu >> 2.0 :: "You can't have your cake and eat it too." >> Also try c186br@holden, c260-ay@ara and c184-ap@torus > >Andrew Chalmers. etac@lv.sait.edu.au David Navas navas@cory.berkeley.edu 2.0 :: "You can't have your cake and eat it too."
