Video/Audio extender question

by GavinR98 Jun 5, 2013 7:12AM PDT

Hello,

I hope someone can help with this question. We have a cat5 to VGA balun and it connects to a HDTV which works great (this is used for presentations). I was asked to have two connections hooked up so that someone at the head of the conference table could use it and someone at the tail end of the conference table could use it. My question is, what would you recommend I use to get this working. I have tried to use a regular vga splitter and the picture quality is awful. I am not sure the best way to do this so any help would be appreciated.

VGA is analog

So it's bound to degrade over distance. Did you look into non-balun solutions? HDMI?

Another all digital method we used.

We use another method for a world wide screen show. We install VNC (too many version out there so take a look) and a second PC where it's needed.

The problem is the cables were run before we installed the conference table and getting any new cables through the conduit is not possible due to the size, this is why we did rj45.

Then other VGA over RJ45 is up next.

That's no balun.

Sewell is usually pretty good and works. Time to call them.

VGA Switch

Is there a problem with video quality with both connections when using the VGA splitter? Does the video look okay on both connections with the splitter out of the equation? If so, then you should try using a VGA switch instead of a splitter.

As was mentioned, the use of a balun might cause video quality to suffer over a long distance. You might want to consider using an alternate method for getting video to your monitor from the switch (e.g. wireless VGA adapters)

When using the connection without the splitter the quality is perfect, it only gets blurry when I use the splitter. I will look into a VGA switch to see if that will help. I have a balun that works up to 300 feet so the distance is fine. I have also looked into a wireless adapter and the quality was not very good on the 3D HDTV, I do however use it on another conference room and it works great but for this room I need another solution. I do think that is does have something to do with the balun as I can do the same setup on another TV with no balun using the same splitter and the quality is fine.
