    VGA over IP/Ethernet

    Hi,

    We currently have one Screen up on the wall in our IT department. We want to move the PC Powering the screen into the Server room so it is out of the way.

    Our next idea was to put up 4/5 more screens around the building showing the same thing all coming from the one computer moved into the Server room.

    I am wondering the best way to do this is. My idea would be to get a basic VGA to Ethernet adapter and plug it into a floorport (which goes back to our server room) and then have a switch on the end of the PC with all of the Screens going into it through the floorports. Would this work?

    If not what do you suggest?

    Any help much Appreciated

    We have a similar thing at work running off Mac's which a local company did supply, they were showing a looped TV type thing in the reception areas. You need some sort of distribution switch, unfortunately I do not know off the top of my head what it was we used but was only a 1U device, if I get chance on Monday I will pop by and get the details from one of our sites for you.

    We've used these - Ethernet to DVI Video Adapter over IP - StarTech.com

    Not sure if you can have multiple devices (but I think you can - when you run the software it asks you to select the screen to connect to which suggests you could have more than one)

    I have a similar system being installed that runs 30 Large Screen TFT's from 4 PC's located around the site.
    Each cabinet has an HP SFF pc with a Video Capture card installed.
    These PC's pick up a live UHF RF Feed on CH47 delivered by Coax to each Cabinet.
    Each PC has an Internet connection and at scheduled intervals downloads pre-defined content from a remote FTP site which then overlays this content with the live RF feed to deliver a branded TV Channel to each screen.

    Each PC cabinet has a Broadcast Device that takes the PC output and sends this over CAT5 to a box on the back of each TV

    Now, none of this was my idea I just had the internet and power provisioning dumped on me at the last minute!

    The company providing this system to many Football Clubs this year has valued the 30 screen system @ £116k (It has cost another £10k to deliver Power and Internet to this installation)!
    No wonder so many of these clubs are running close to bankrupcy!

    Any way, I looked at ways I could do it myself and I decided that the LevelOne stuff was extremely good value and could do the job at a fraction of the price these cowboys are charging.

    http://uk.level1.com/category2.php?id=22&id2=123#0
    LevelOne - HVE-6000 Short Range HDMI Receiver

    They also do DVI/VGA and Audio only.

    Im just playing with sending the HDMI signal from a laptop upto a projector at the moment using this stuff but as I get more into it I can see many more possibilities for it.

    If you need any help sourcing this stuff just PM me.

    If I am right in thinking these can not be used over a 'network', they are just using the media? If so you would need a hub so it sent the same image to all converters and screens? But never experienced these before so not sure.

    Not in the sense of just plugging stuff into your existing Cisco and getting a picture somewhere else.

    You can get a piece of active kit to convert your signal to run over CAT5 cable, but it won't distribute via standard switches or hubs. You could get a video distribution gizmo that you could site in your server room but you might need to buy a pair of converters/baluns for each line you want pictures on. Look at Kramer kit, it is at the lower pro end of the market, but it does work well.

    e2a - the Cobra range looks just like the stuff you will need!

    I've read of a new standard for distributing HD over CAT5 that would be worth a look at too, but I don't think there is any kit available yet

    We use these across our school on 5 or 6 screens all showing the same information powered by one PC.

    we have 4 screens around the building all VGA over CAT5 from one central computer which has a splitter to support 4 computers we have used several different vga to cat5 and found some flicker or dont last long, we have tended to find that we get what we pay for. The ones that we have found most reliable are

    KRAMER|PT-110|CAT5 TRANSMITTER, XGA | CPC
    KRAMER|PT-120|CAT5 RECEIVER, XGA | CPC

    or we have used this one

    Another option is to buy a Acer R3610 and slap it to the back of the screen. They can be picked up from £180, although ebuyer currently have them at £200

    We've got 3 of them powering the 3 screens in our NOC. Decent units for the price.

    Attached are some images of one of our units we use, it connects to the MacMini and shows something on the TV screens. I will get to the other site and look at the 1U unit we have there as well.

    This question came up about a week, maybe two back. I found some Kramer kit that would do it. Worth a search.

    Edit-

    Hang ON! The OP started the thread with exactly the same title!

    I'm going to merge this thread with the duplicate one created here as it got more of a response.
