Re: 1084s Monitor as a preview video monitor on PC. Possible?

I see. Thanks for the link. As you mentioned, basically I am trying to connect my IBM ThinkPad, with various emulators (SEGA, SNES, MAME, NEO.GEO, etc.) running on Win XP, and connect it to my 1084S-D1 monitor. The ThinkPad LCD (or when connected to a regular VGA CRT monitor), shows the graphics pixellated (I don't like to turn on those software based filters, to smooth out the image), so that is why I am trying to connect it to a 1084S-D1: The S-Video smooths out the image considerably, but it has flicker (I even set the refresh rate under Windows settings to 75Hz and still see it).

Can anyone verify that the device which desiv posted would work?

Thanks, I have already connected my IBM ThinkPad to 1084S-D1 that way (S-Video to Luma/Chroma), but I was under the impression that if I connect it via VGA to RGB, I will get a better/flicker free image (superior to S-Video).

I will post the images shortly...

No even if I use software 15khz or similar software?

Here are the screen-shots of my S-Video connection to Luma/Chroma:

The first two of from my ThinkPad's LCD, showing you the settings that I am using, third image an up are the actual screenshots of the gameply on 1084S-D1.

I think they look pretty good.

Thanks! OK one last thing:

If I order this cable:

http://site.ambery.com/webgraph/CGA-VGACable.jpg
http://site.ambery.com/webgraph/CGA-VGACable-Connector.gif

Can I connect my ThinkPad via its VGA and connect the other end (9 pin) In combination, can I use a 15Khz software that lets me lower the resolution/frequency of ThinkPad to match 1084S-D1?

I connected my real Amiga 2500 (via 9 pin to 15pin) and its image is superior to that S-Video that I am getting from my ThinkPad.

there is got to be a way to convert VGA to RGB with superior video quality over S-Video. Right?

This 15KHz software you speak of probably only affects the timing of the VGA port.

I assume so as well..., since it will "fool" the monitor that it is connected to an older device (i.e. Amiga, Atari, etc.)

As you know, if you connect a real Amiga to 1084S-D1 via S-Video it looks inferior compared to when you connect it using a DB 15-pin to DB 9-pin cable.

If I determine what is Amiga's native resolution/frequency when connected to 1084S-D1 via a 15pin to 9pin cable, then I might be able to buy a VGA to DB 9-pin, and in Windows environment somehow change reslution/frequency, so my MAME and other emulators, look as sharp as when a real Amiga is connected to my 1084S-D1 (again using a DB 15-pin to DB 9-pin).

Surely, 1084S-D1's RGB port, somehow must be able to receive a comparable signal from ThinkPad (or a modern computer for that matter), and convert this into something comparable to a real Amiga video signal. My issue with S-Video (from ThinkPad) to Y/C on 1084S-D1 is that it is NOT as sharp as when you connect a real Amiga to 1084S-D1 using a a DB 15-pin to DB 9-pin cable.

Well, what is through software in Windows (PowerStrip, 15Khz, etc.) I might be able to adjust this?

Someone is making a progress here:

There has to be a way...

Looks like it is possible and have been already done here!

http://www.dragonslairfans.com/smfor/index.php?topic=127.0

"No need extra converter, VGA to SCART in RGB will work fine BUT you'll have to use AdvanceMame under DOS, or, more easy for setup : buy an Ultimarc's ArcadeVGA and you'll be able to use windows. I strongly suggest you that option if you never worked under dos and AdvanceMame config"

Yes, you did, thank you. The reason I was using the laptop was the fact that it had a video card that supported S-Video out, but when I installed the soft 15Khz, the utility did not detect its GPU (not supported). On my Desktop PC, which has a nVIDIA 6200 (AGP), it detected the GPU and installed the soft 15Khz. The only thing remains is hacking my VGA to DB9 cable and to test it out!

Thanks for your response. I am having someone hack a VGA to RGB (15 to 9) cable for me, and I have asked his to use this schematic:

http://www.dragonslairfans.com/smfor/index.php?topic=127.0

(The first message in that thread, by user named "DarthNuno")

The thing is, I am not entirely sure if that is accurate or not.

For example this page, has a different pin schematic:
http://www.gamesx.com/hwb/co_C1084dd.html

And user named "funkycochise", in this forum, has used a yet another one:
http://www.dragonslairfans.com/smfor/index.php?topic=127.15

On male connector witch to be plugged on the female of the monitor :

1. Gnd
2. -
3. Red
4. Green
5. Blue
6. -
7. Sync
8. -
9. -

Would you kindly verify WHICH ONE is the correct pin layout/shcematic please? I don't want to have this guy make this cable (he is charging a bit high) to realize that is not the correct one! Any help would be greatly appreciated!
Kind Regards,
CodeHunter

OK, my first attempt is not successful I guess. This is what I did:

1) I went out I bought a D9M-15HF "Gender Changer" adapter, and a male Db9 Serial cable. (already had a male-male VGA).

2) Installed 15Khz soft utility on my PC desktop (nVIDIA 6200 AGP, which has 1VGA, 1DVI and 1S-Video out)

3) lowered my resolution to 640x480.

4) Restarted Windows XP

5) Connected my 1084S-D1, via the cable contraption that I mentioned in step 1.

6) 1084S-D1 only displays garbled red video signal. I even changed my VGA cable for a different one, pressed on buttons in the back of 1084S-D1, nothing changed however.

All screenshots are here:

I am asking someone to make a cable for me, according to the following instructions:

http://www.dragonslairfans.com/smfor/index.php?topic=127.0

So hopefully I have better success with this one.

I will keep you posted.
