No Sync

[Ton van Bochove]

I purchased a second hand first generation CDU of FDS and a lower EICAS monitor. Both devices are VGA. The FDS software works perfect and the new CDU is seen and functions as a center CDU. But both monitors show "No Sync" I understand that the used VGA-USB A connection makes no connection. An alternative can be that I use a VGA - HDMI - USB A connection but I am not sure if this is the right one. Can anybody advise me on this?

Brain works slowly but sometimes you must use another angle, so let me rephrase my problem:

I have a laptop with one VGA, several USB A and one HDMI connector. On this laptop PSX is the server.
I also have a FDS CDU/HDMI, a CDU/VGA and a monitor for the lower EICAS/VGA.

-FDS CDU/HDMI: HDMI-HDMI connection works perfect
-lower EICAS/VGA: Did not try it out yet but a VGA - VGA cable should do the job

But now the problem: How to connect the CDU/VGA? I think VGA-USB is not the best connection ( NO Sync until now)
Is a VGA - HDMI connection a better choice? with a splitter, adapter or anything else? How would you guys solve this problem?

USB-VGA should actually work, I did this often in the past for monitors that were not demanding in resolution and refresh rate. CDU and EICAS are perfect applications for such a link.

The first thing is to figure out which end of the link doesn't work.

Is the PC recognizing the USB side of the USB-VGA adapter and claiming "this device works normally"?
Can you get any other VGA monitor to display a proper image using this USB-VGA adapter and just the normal desktop or extended desktop or whatever, no PSX in sight?

If this works, then move on to the CDU monitor, just displaying your PC desktop. And then slowly further with PSX.

You have two VGA systems there - a CDU and a lower EICAS. Both are plain VGA monitors. Try them both on a plain VGA cable to your VGA PC desktop output to see whether they work that way. Rule out defects in the individual systems before you combine them into a more complicated system.

Jeroen, Bedankt. Sometimes I make things to complicated I will check the VGA-VGA connection

In the last couple of weeks I have been trying to connect the VGA CDU to a computer with a VGA connector so a straight connection. The result is still zero: no synch. Than I used a VGA cable and a VGA-USB-A converter which gave the same result. I tried to make the both connections to another computer: same result. Than I dowloaded a NVDIA VGA driver.....no result.

Are there any owners of the FDS CDU with the VGA connection on this forum? I like to know how they installed the CDU ( driver from FDS?, just PnP)

I use a mini-DP to VGA cable. Shows up as a normal monitor. To get the screen to turn on, you need the USB connection and the tekworx drivers.

That sounds promising.....but I cannot connect a mini Display to my computer. Would the DisplayPort do the same job or is it another standard?
