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

[desiv]

I'm not quite following all your steps..

My current connection is as follows: I managed to obtain a S-Video (one end) to DUAL female RCA.

OK, good, so from an S-video plug to dual RCA.  So far so good..

Then I obtained a Male RCA, Y-Splitter cable (all three ends are Male), and connected this to my S-Video cable above.

What?
Did you just take both RCA plugs (Chroma and Luma) and join them to a single RCA plug?
If so (and I'm not sure), that's no longer s-video..
Or do you have 2 Y splitters and you are just using them as a gender bender???

Then I connected one end of the cable (S-Video) to the back of my IBM ThinkPad, and the other TWO Male RCA connectors to Y (Luma) and C (chroma) of my 1084S-D1.

And this is where I'm totally lost..
What happened to the Y splitter?
You need to go from s-video to separate chroma and luma, and they have to stay separate all the way to the monitor...

I'm sure I just misread something...

I'm pretty sure all those units are for taking a 15khz screen (Amiga, old video game console, etc) and displaying them on a VGA monitor.

You are talking about taking a PC and scaling it DOWN to 15khz for RGB.

I haven't seen that type of hardware...

I have seen some drivers that can do that type of thing for using a DOS MAME PC with an Arcade monitor.  And the ArcadeVGA card can do that with full Windows drivers, but that doesn't sound like what you want..

If I understand it, you want to preview whatever is on your PC in whatever resolution to the 1084s.
In that case, a VGA to S-Video adapter is going to be your best bet, I think....
(And many (well???) laptops and PCs already output s-video...)

No, you're looking for something like this:

No idea if / or how well it works..  
But it matches the description.
You'll still need an s-video to separate chroma/luma cable to connect that to the 1084s.

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).

Nope.
The 1084S flickers with interlace resolutions.  Just it's design..  (Zac67 beat me to the answer..)
And you'd have to downscale your Thinkpads resolution and frequency to something the 1084s understands on RGB.

I haven't seen a device that does that...

s-video is going to be your best bet, but s-video is generally pretty darn good to be honest.  ;-)

Not even if I use software 15khz or similar software?

It's not the 15khz, it's the vertical resolution.
If you are only showing a low-res screen, like 320x200 or 640x200, there's no flicker.
But when you up the resolution, you get into "Interlace" ranges, (320x400 or 640x400) and those flicker on the 1084, no matter what..

Yeah, those pics look pretty good.  I don't think you'll get much better than that.. ;-)

Tcan I use a 15Khz software that lets me lower the resolution/frequency of ThinkPad to match 1084S-D1?

You can try something like Advanced MAME, which lets you tweak your video settings to output 15khz, if your video chip supports it.
Never tried this, but it might work in Windows:

I think you can do similar things with PowerStrip.

Warning, sending wrong signals to the monitor could damage it...

"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"

I mentioned AdvanceMAME above.. ;-)
I didn't mention ArcadeVGA as you have a laptop.  It's a card for PCs..

And if your chipset is supported by soft-15khz or powerstrip, you can use those.
