Will this monitor work with an Amiga?

Hi all

I am thinking of buying a Mitsubishi Diamond Plus 200 for my Amiga - Inintend to get an RGB to VGA converter. My question is, will it work?

These are the specs for the monitor:

Thanks

Hi Sanxion

I know mine works after Googling it which is a SAMSUNG LCD SyncMaster 2032MW.

I know it is all about the 15Khz RGB Signal.

Have a look at this LIST http://15khz.wikidot.com/ to give you an idea what to look out for. I know, my monitor is not mentioned.

And have a SEARCH on this forum, lot of people have asked this question.

It seems to cover 30 to 108 kHz, 50Hz and up and so needs a scandoubler for 15 kHz modes.

Thanks for the responses...

Excuse my ignorance but which modes are the "15 kHz" ones that will not work?

No need to excuse yourself

I just Googled this --

Video monitors, such as the Commodore 1084 series, accept only the standard Amiga 15 kHz scan rate (NTSC and PAL display modes); a television is considered a video monitor.

http://wiki.amigaos.net/wiki/AmigaOS...red_Scan_Rates

http://oldwww.nvg.ntnu.no/amiga/amig...igaFAQ_18.html

I'm a tech noob, so I hope this helps.

All screen modes generated by an A500 are 15 kHz.

I have one too, good for the money and new in box also.
There is a lot of light bleed around the edges which would bother me if I was using it for a working pc display.

Depends on what you mean by 'RGB to VGA converter'. If you mean a simple adapter like this one:

- then I am 99% certain that it will not work. To use that monitor with PAL/NTSC modes, you will a scandoubler which will convert the signal to >60 Hz Vsync. For A500/A600, it could be Indivision ECS.

Since that monitor is made for high-Vsync PC modes (good for gaming) it has very fast phosphors, which means it will produce a very flickering image at 60 Hz, so it would probably not be very nice to use with the Amiga.

Will the NEC mentioned here work with a standard RGB to VGA converter?

Not any one will work. Bought one from one of the Amiga dealers and would not work on mine. I believe a seller on Amibay (Pavlor) is the one who sold me one and works fine. He makes his own.

I have an Amiga 4000/040 running through a quite large Mitsubishi Diamond Plus 92 but then I do have fitted the Picasso IV. I have a couple of 1200s with the old Scandoubler flicker fixer thang and they run on IIyima monitors. For the most part I use Microvitec monitors which in truth were bought during the nineties. I have a 1200 on a scart running through a Samsung Syncmaster T220HD. Getting difficult finding TVs with scart. I have a large Toshiba a large SONY Trinitron and small SONY Trinitron that run the scart and do quite a good job. Not sure about the picture ratio on modern flats never looks right prefer the old CRTs in truth.

The issue with the Amiga is the flicking around with scanmodes. The Microvitec in truth has been just perfect. Only one is a little dull now but for the best part have been great tools. All the Commodore models still work even the 1942 so if you can get a 1*** series monitor or even the Philips then you will be made especially as they carry the sound also. Don't forget that unless its a TV based monitor it wont have the sound so you will need speakers or headphones.

The A3000T runs on an Iiyama VisionMaster with no help.

You can also run the Amiga through a video player but we are talking old technology here when the the world was composite and scart and even bnc twist-on video. I have one Microvitec that has no less than 5 bnc twist type video connectors connecting to an Amiga 1500.

I have never had much luck with VGA and PC style monitor frequency. Never seemed to work for me. I have a tin full of those VGA connector things especially the silver A4000 jobby and thats where they stay, in the tin.

here is the user manual, this place shows 31.5khz for the lowest res, so no this will not work on amiga without a scan doubler.

https://www.manualslib.com/manual/29...?page=7#manual

"
Digitally controlled auto-scanning is done using an
internal microprocessor, for horizontal scan frequen-
cies between 30kHz and 108kHz, and vertical scan
frequencies between 50Hz and 160Hz. The micropro-
cessor-based intelligence allows the monitor to operate
in each frequency mode with the precision of a fixed
frequency monitor"

If you talk about the adapters then there is a difference yes. The original C= adapters have a buffer circuit inside for the sync signals and some of the cheaper versions do not have this.

Just because the manual specifies 31.5kHz as the lowest doesn't mean it will not go lower in practice. It will just be out of spec then. My Dell 2001FP which works with 15.6 kHz also specifies 31.5kHz as the lowest in the spec sheet, like all VGA monitors do since VGA is not lower than 31.5kHz. But being a CRT, it is unlikely it will work well below the spec and if it did, the picture would flicker like crazy.

The monitors on this list seem to be TFT. Does anybody know of a good CRT monitor that will work with 15 Khz?

My understanding is that these produce better results with the Amiga video modes or does not matter?

It's not a matter of knowing a good CRT, it's a matter of getting hold of one.
Only a promille of all monitors will work with the Amiga.

If you just want to use PAL modes, then a regular CRT TV will do the trick. If you want a real monitor, you can choose the Commodore/Philips ones like the common 1084/CM8833 or the higher end multisync models like the Microvitec ones if you want it to work in both PAL and hi res modes. Multisync monitors are not easy to find though and usually quite expensive.
Here's a good list of monitors that should work:

Thanks...I already have a M1438S...but having used "huge" monitors with PCs for years now, I would like sonething larger for my Amiga.

Also, what do you think about the NEC AccuSync 92VM - it isn't on any of the lists but the "AccuSync" range does appear.

Then get a CRT TV of suitable size before they're all thrown away, or get a 20 inch PVM.
