VGA Type connector from monitor to computer - cant tell what kind it is

156 Views
Last Modified: 2017-04-25
HI - So i'm doing some work in a dental office where we replaced some old computers with new ones. At each station the have 2 monitors, one on the countertop, and one thats mounted above the patient so they can see Xrays etc. I purchased Lenovo SFF S510 computers, that have both VGA and displayport ports. The problem I'm having is that the cable connecting the monitor on the countertop appears the be a standard VGA cable, and works fine when connected to the VGA port. The other cable coming from the mounted monitor APPEARS to be a VGA cable, and when plugged into the VGA port on the computer, doesnt display a signal from the computer as if nothing is connected to it. When I look at the pins on this "VGA type" cable, there is 1 pin missing.  On a standard VGA cable there are 15 pins, and on this cable there are 14 (as shown in IMG1 attached) - The other interesting this is about a foot from this "VGA type" connector (on both sides) is a larger type connector that I can disconnect from the rest of the cable (shown in IMG5, IMG4 and IMG2) - I'm not sure what type of cables these are, and I cant get the displays to both work. Thinking these connector were standard VGA cables, I've tried displayport adapters, and I just cant seem to get it to work. Does anyone know what this is? Any help would be appreciated!

Hello Hodgem

This must be the issue of parts assembled wrongly
into first image it is clearly visible that the 1 pin is missing,
I would suggest you best option, please resolve the issue calling system hardware engineer onsite and change those explaining the issue.

This might create issue if you try randomly changing connector and wire, be careful while in running mode and you are changing connectors and cable port

It seems like a VGA cable extension, is it connect to VGA Port on the back of computer from the other side ?

Call the monitor manufacturer's support line and see if you can get a manual for it.  Medical equipment tends to have non-standard connectors, sometimes due to FDA approval issues, sometimes (I suspect) so that you're tied to that vendor.

Need some better clues.    The failing monitor has what kind of cables directly connected?   Concerning the box to which the computer vga cable connects does it have a model number? Vendor ID? Do have a good pic of it?  

The round cable you are showing could be a proprietary cable for video and power to get to the overhead monitor, assuming that monitor is somehow built into the dental chair.  In which case the box (I can barely see, might be the device that connects it).  

It would be helpful to start at one end (say the monitor)  with a pic of how it is mounted and if visible how its power and video cables are connected.  Then got towards the computer to the next device/box/converter and see how those plug in, then on towards the next until you get to the cable  that plugs into the computer.  Show more than the cable ends, but also what they connect into and any associated part or model numbers.

@Ramin - Yes, it looks like a VGA extension based on the link Arana sent. At first I attempted to simply connect both monitors to the computer using a VGA splitter, when that didnt work, thats when I decided to use the displayport adapter to connect the other monitor, then THAT didnt work.

sorry i cant be of more help but I guess knowing that it is a 15 DIN connector puts you in the right track

Probably they used Dual Panel-Mount Cable to have it on two monitors.

dont try to be a half engineer if you really dont know what to purchase in right order, be sure prior to purchase any product, until and unless you are sure that you can fix by purchasing product suggested to you
If you are not an expert and lack of know-how then I would suggest you to call system doctor -> a hardware engineer who can identify the issue and fix if for you

I'm also agree with Joan, If you don't know what exactly are you doing then call someone to do it for you.

@fred hakim - here is some more info:

The failing monitor has what kind of cables directly connected?   Concerning the box to which the computer vga cable connects does it have a model number? Vendor ID? Do have a good pic of it?

The round cable you are showing could be a proprietary cable for video and power to get to the overhead monitor, assuming that monitor is somehow built into the dental chair.  In which case the box (I can barely see, might be the device that connects it). --------------------- It looks as if the round cable is an extension cable because the same VGA type connector is on both ends (going into computer as well as monitor) The mounted monitor has an independent power source like a typical monitor does.

It would be helpful to start at one end (say the monitor)  with a pic of how it is mounted and if visible how its power and video cables are connected.  Then got towards the computer to the next device/box/converter and see how those plug in, then on towards the next until you get to the cable  that plugs into the computer.  Show more than the cable ends, but also what they connect into and any associated part or model numbers. -------------------- If I was to start at one end (please see img2) and see where the other end was coming out (please see img4) that's it - the rest of the wiring is under the floor and not visible. There doesnt appear to be any "converter" involved, like I mentioned, it looks like the rounded cable appears to be an extension cable.

Boot the old computer and see what Device Manager shows for the "Display adapter" => looking up the details of that adapter may help resolve this.

Which cables were actually connected to the 2nd display?    It sounds like it uses a DIN input connector, but you didn't note what was actually connected to it.
