Split VGA signal without quality loss ?

i wasn't sure where to post this question so im posting here, sorry if this is wrong category

I have a DVR computer with security cameras and i want to display the same image on another monitor. I only have 1 VGA output, so i really need to split the signal.

I bought a cheap Y splitter like this one

But i ended up not using it because there is an important quality loss

So i'm looking for an alternative without quality loss.

I found this from monoprice:
http://www.ebay.com/itm/2-Way-SVGA-VGA-Splitter-Amplifier-Multiplier-300MHz-/370543547116?pt=COMP_EN_Networking_Components&hash=item56461dd2ec

Will i see a quality difference with this item ?
Also, what is 300MHz? There is also 400MHz version for more money, is there a noticeable difference?

thanks !!

More about split signal quality loss
  1. You can use the two VGA outs on the GPU to get the same image across 2 monitors too. Without quality loss though.
    If you are using a GPU and not the onboard IGP. A cheap nearly extinct Video card might do the trick.

    no choice for adding a graphics card unfortunatly

    the linked item looks ok but to be sure pop into a local electronics store (Jaycar in Australia) and ask the question.
  3. Yeah it's a DVR computer made with intel atom and a shitty motherboard with only 1 PCI slot and its already used by the DVR card so i cant get a video card. And there's only ONE video out on the motherboard

    It is a DVR COMPUTER not just a DVR.

    You can try using one of them Multiple Display Boxes, but they're not going to be that cheap I think.
    You might as well just change the Mobo and Processor to a Llano Set. It'll be well worth the Headache. I really can't see an Atom keeping up with the Cam feeds..... I don't know how they managed it, but, I'd love to know the Model and make of the DVR Computer you have, specs would be good too.
  6. I built that DVR computer myself.

    back 2 weeks ago, i was using a Pentium4 1.6GHz with 256mb ram for running 5 cameras live.

    I wanted something more silent without fan, so i upgraded to that :

    With only 2GB Ram and it's doing the job very well with Geovision Software

    Well i found some of them on ebay for less than $30, and newegg are selling one for $45

    I just want to be sure there won't be signifiant quality loss like i had with a traditionnal "Y" vga splitter
  7. Could you send the links on ebay for those items or give me he model number and make so I can check there quality of the videos and let you know.

    Image quality on both images seems to be perfect with no degradation.
    Also a 400MHz Model by the same company seems to have a better market review than the 300MHz model.
