Serial to VGA

Specs: Windows Vista
I'm trying to help a friend who has a magnifier for his daughter that is hooked to a large and unwieldy CRT via serial port. He'd like to use an LCD monitor instead. Is there a way to go from serial to VGA? here is a link of a similiar unit. Thanks

Are you sure it's a serial port? CRTs and LCDs have VGA connectors that look similar to a serial connector, but it has 15 pins instead of 9.

Yes. the female jack on the unit is 9 pin. Here is a similar unit

I don't see anything plugged into that 9 pin jack. I wonder if it's a serial port used for some other purpose, and the video is actually coming in on that small cable down and to the right.

Anyway, I don't think I can be any help. I doubt if you will find a serial to VGA adapter.

yes, thats not his unit. Just an example he sent me. He said he is using the serial connector. I'll have to talk to him some more. Thanks for looking.

If your unit is anything like that, It looks like the "serial" plug is for some type of RGB connector (As indicated by the switch) The other input is a standard AV composite plug. Maby a cheap LCD TV could be used?

I should have mentioned, he did say his model does not have any composite jacks.

clipperqb, If you look very closely at the lower right picture you will see that it's that small cable that carries the video. The jack that it plugs into is labeled 'Video output'.

And I believe that the 'RGB <--> Composite' switch refers to that cable and not the 9 pin connector above it.

I don't believe any company would use a connector that is universally used for serial ports for some other purpose.

I suspect that getting (or building) an adapter for that special cable would be extremely difficult.

It would be helpful if we knew the exact model we are looking at instead of this item that is almost the same but isn't. If we can see the exact model then it would speed things up but so far it's just guessing.
