HDMI to Multi including S-Video

[rybussell]

I have a computer with two HDMI slots, one on board and the other on my video card...

We have a tv that we connect to with HDMI and a projector that requires S-Video...

My plan is to connect the HDMI to a HDMI splitter and then get a converter that turns the S-Video to HDMI and connect them both to the splitter... A couple websites I've came across say it's not possible and that anyone trying to sell that kind of converter is lying.

So what I'm asking is, is there an adapter to convert an S-Video to HDMI, or better yet, a hub I can run the HDMI into that outputs to HDMI and S-Video? I hate searching google and seeing the conflicting statements.

i assume you're only using the HDMI output from your vid card, and not the onboard one, right? if so, does your vid card have a DVI-I or VGA output as well? if so, use that, set to mirror the outputs from within Windows, and then find a VGA-to-Svid converter, which should be infinitely easier.

if you don't have such a card, buy one. MUCH simpler solution than the paragraph that follows...

the reason that an HDMI-to-HDMI+Svid splitter doesn't exist is because you're likely the only person on the planet who would want one. technically it's possible, but nobody has really bothered to design & build one (except maybe some specific niche markets where you'll likely pay $500 for the unit at the least). basically, you want an HDMI replicator with a DAC to take one of the replicated HDMIs and make it Svid - with appropriate resampling to a lower level.

In theory it is possible to active convert HDMI digital signals down to analog, for RCA and S-Video.

It is ONLY possible to go from digital to analog, not vice versa. And it requires active conversion.

I suppose a repeater/converter box like this one should work

Yeah.. Using the video card.. It has an HDMI, a DVI, and a VGA. With the program I'm using, I need one screen separate from the other two which should be identical.. So essentially monitor 1 should be windows, monitor 2/3 should be something completely separate. I've never worked with more than two monitors.. Is it possible to, with three monitors, only mirror two of the three and have the third one be completely separate?

since i didn't know, i checked:

yes. (at least in my case)


i'm running a GT610 on two* screens, plus a 9400GT on two screens. i can have extended desktop to use all four (1,2,3,4), or i can mirror the 9400's output so that i have 1,2,3,3


* actually 4 screens but Win7 sees it as 2, and the card splits each of the two into another two, so... yeah.

ok, so... if you want 1,2,2 then i'd suggest 1=HDMI, and use VGA for 2,2 because it's likely much simpler to replicate VGA signals with some outside box.

First two lines made me laugh actually... Thanks.. I'm just going to do as you suggested and find a cheap VGA/S-Video adapter.. Thanks.. Do I close this question out or what? Haven't been on the site in a while before today...

Maybe tell us your ideal end result. Exactly what card are you using? What do you want to display on each display device, and what inputs do those devices accept?

 

[giantbucket]

keep it open and update once you've tried it out. if what you try works, then post so that someone else can learn (i dunno, 6+ billion people on earth, someone else is bound to want to try this...)

It's an XFX 6450 Radeon HD or something like that. I really don't remember the exact model. It has 1 HDMI, 1 DVI, and 1 VGA.. I have a software program that churches use and it uses one screen to run the program and the other to display the actual presentation.. And the church I'm putting this together for actually has a HDMI TV and a projector that it needs to display the actual presentation on both...

So what I think I'll do based on this thread is run the HDMI straight to the HDMI TV, then run the projector and PC on the DVI/VGA ports...

 

[huilun02]

HDMI > straight to TV

DVI > to the screen running the program

VGA > convert to S-Video > projector

So all you need is one VGA to S-Video cable
