Cascading Displays with PC Video out; native resolution only on source

I have a situation here where 1 PC is used for source video which will be displayed on several other monitors. And when I say video, I mean still frame type content i.e. PowerPoint etc. However, it just so happens that these monitors are actually 47" Vizio 1080p tv's.

Here is the setup we currently have in place: and Dell Optiplex GX520 with a ATI Radeon x1550 video card which has VGA out and S-Video out. The VGA out goes to our main monitor (but the same Vizio 47" as the others). The S-video out we have going into an RF modulator which then outputs into coax which is ran around our operations floor to the other 47" displays.

The problem is this: We can only achieve native resolution on one monitor (1920x1080) which is our main one through the VGA connection. The other displays are clear (with one small pretty insignificant detail), however the resolution is displaying in a different mode. Not quite 800x600, but somewhere in between. The insignificant detail I referred to is a lime green (and sometimes red) haze, for the lack of a better word, but it's only on the desktop area background and does not impose itself onto the open window.

Any recommended video card for this purpose? Any other expert suggestions?

Your problem is the way the video signal is going out - s-video will display something like 640x480, but no better.  Converting it to RF only makes it worse; RF is the lowest quality video transport, even lower than composite video (yellow RCA plug).  The green or red haze is interference being picked up along the cable.  You really should be using component video (red, green, blue cables) to display HD resolutions, but that means running three cables to each television, not one.

I know this can be done with component, VGA, or even HDMI.  I have all those options as the tv monitors. i just preferred using the RF in to each because the coax is already run and all we need is a basic splitter with a few amps mixed in along the way. Simple, and already in place. Now with the other connection types, I'm going to need to buy some sort of hub or video switcher unit. And I'm not even sure about these video switcher units will broadcast to all the monitors at once. There are so many products out there that seem to fit this mold, and very expensive ones at that, and I just need a simple solution here.

VGA might be the way to go here.

A VGA distribution amp would work - I use a Kramer VP-300, similar to this 4-port version http://www.proaudiosuppliers.com/kramer-vp-400.html.  You can cascade them to get as many simultaneous displays as you want.

After more research, I decided to go with a solution by Avenview. I've determind it's the easiest and most cost effective solution for this application.

An 8 Port VGA transmitter via cat5 along with 8 VGA receivers via cat5.
