Best way to upgrade

Hi everyone,

Here at our facility we run a constant powerpoint that runs from a computer (obviously), feeds into a device called an autopatch (http://i392.photobucket.com/albums/pp4/mccominc/Mccominc4/AutoPatch1Y-16pic3.jpg), which than feeds it to roughly 13 other televisions. Since upgrading a few of the televisions to larger LCD televisions (47" 1080p, 60 Hz) we have had a serious lag issue with some of the commercials that are running. I believe the resolution the computer is outputting is much too low. Essentially our goal is to upgrade the computer with either a new one or upgrading a different one we have in the facility (Dell Dimension 2400). From what I researched the Hertz or resolution is the common issue. I verified, both the computer and television are outputting at 60 Hz. When I messed around with a higher resolution it seemed to help out the issue, but lag down everything. However, we are running into several issues.

Right now the computer monitor is hooked up through a VGA cable straight from the computer. The televisions, which are fed from the Autopatch, are hooked up through a RCA cable (Video only). However, we are running a S-Video out from the computer which turns into a split RCA video cable to feed the televisions. The other computer we want to try out doesn't have an S-Video or a RCA video out. I figured we could split the vga signal into two, but the Autopatch only accepts a RCA video cable.

Our goal is to keep costs down, so upgrading the Autopatch system is probably way out of the question. If this makes sense to anyone, what would you recommend? We tried contacting our local computer stores for their input but they didn't have the necessary video card with an S-Video.
 
Hello ECsports

I'll be perfectly frank and state that I cannot help with regard to your issue except to point out that the connectors on the back are not RCA connectors but BNC connectors.

Ahh, yes you are correct about that. Is it common to have a BNC cord connected into a video input on a Television?
 
Well I've never seen a BNC connector on any TV ever.

They did however have BNC RGB connections on computer monitors at one time.
 
RCA connections on a TV are common place and are usually accompanied by an SVideo connection.

This will be an AV connection which may be AV 4 for example.
 
From what I know about the resolution and refresh rate...60hz is fine. The resolution should really be set at whatever is native for that display.

My concern is using the s-video connection at all. Especially once you split it and then convert to the BNC....I have to imagine that's where you get the lag. From my experience, it's always better not to convert to other display standards if you can help it. Though I'm no expert on the subject
 
Would finding a RCA video out video card be an option than?

I worked with televisions for numerous years and I also do agree, the more it's split the more potential of video lag.
 
i'm wondering if it would help you to get a nice graphics card with those display ports that are made for running like 6 or more displays, where it is a small little rectangle thing or something, never seen on in life cuz they are expensive so idk, but i knoe they are split into 2 feeds normally, and they have like 3 or 4 meaning 8 feeds.
 
I would also like to add; when it goes from a picture to a short 15-30 second video clip during the powerpoint slideshow it takes a good 1-2 minutes for it too load now.
 
Here is something interesting...how can adding two new LCD televisions slow only the videos on the PowerPoint? It's to the point where it takes anywhere from 1 - 3 minutes for the video to load. The actual PowerPoint slides load just fine.
