Hi, I have an Acer AL1715s monitor and the VGA cable is cut about 5 cm from the backside. The monitor has no VGA input on the back but is connected inside with a 13 pin connector. I have to make a new cable and to solder the connector. But I do not know witch cable to connect to witch pin. I am using a standard 15 pin VGA cable (VESA DDC2). The red, blue and green video cables and their corresponding ground cables I can recognize, but the remaining 7 cables I don not know. I have tried to find a scheme on internet but without any success. It has to be costless because I don?t know if the monitor works properly. Gretaings from Jan-Peter in Sweden.

If you have two separate computers for different purposes, such as personal and work use, you may find it convenient and necessary to connect both to a single monitor. Many monitors have dual inputs, making such a connection simple. However, you might need a keyboard, video and monitor switch to accomplish this task if the monitor lacks a second input. Dual Inputs
Step 1 Examine the back of your monitor for the presence of dual video inputs, such as a single VGA and DVI or HDMI output.
Step 2 Connect the VGA cable to one computer. Plug the other end of the cable to the matching input on the monitor. Rotate the retaining screws until tight at both ends of the cable.
Step 3 Plug the DVI or HDMI cable into the back of the second computer. Insert the other end into the monitor's digital video input. Screw down the retaining screws if you're using DVI.
Using a KVM Switch
Step 1 Ensure both computers are turned off. Place the KVM switch on your desk where it is within convenient reach.
Step 2 Locate the video output port on the back of the KVM switch. Plug a VGA cable into this port. Plug the other end of the VGA cable into the monitor.
Step 3 Plug the VGA monitor outputs from each computer into the inputs on the back of the KVM switch. Tighten the retaining screws down for each connected VGA cable on the computers and the KVM switch.
Step 4 Plug the keyboard and mouse cables into their respective outputs on the KVM switch. Plug each set of keyboard and mouse cables from their ports on each computer into the matching inputs on the KVM switch. Plug each cable in sequentially to avoid mixing them up between machines.
Step 5 Double-check that the mouse, keyboard and monitor cables leading from each computer all correspond to the right machine. Plug the KVM switch's power cord into a nearby AC outlet or power strip.
Step 6 Turn the computers and monitor on to verify the connections are correct.

Required Items

• VGA cable
• DVI or HDMI cable
• KVM switch
• Power strip (optional)

Press the Function Button to open the short cut menu. Locate the Input graphic and press the button for it. Each time you press the button, it will cycle between DVI and VGA input jacks. Allow a few seconds for the display to switch inputs. Make sure that cable is connected securely to the associated jack in the back of the monitor and the computer (or other source). If either VGA or DVI input is selected ,but the VGA and DVI cables are not connected, a floating dialog box indicates:

"No Cable Connect" or "No Signal"

Good luck!

DVI ==> Digital Video Input
If your monitor has both DVI and VGA inputs,
and your PC's video-card has both DVI and VGA outputs,
then buy a DVI-to-DVI cable, and use it, for a better picture.
If your monitor has both DVI and VGA inputs,
and your PC's video-card only has VGA output,
then use a VGA-to-VGA cable.
Or, purchase a video-card with DVI output,
to replace the video-card with VGA output,
and then use a DVI-to-DVI cable.

wronge connection check it

There are two types cable to connect to LCD Monitor. VGA and the other is DVI,ight need DVI cable it has flat pins and is larger than the VGA small round pin models.

Most of the Widescreen monitors come with DVI as well as VGA connector. A VGA connector and DVI connectors are different in many aspects. First of all the DVI connector would be white in color and VGA would be blue.
VGA connector has 15 pins and DVI has 24 +1 pin

use your fn key together with f4 from your keyboard. it will display to your monitor.

You will have to buy a 13 Pin Din Male Connector cord. Use the break-down below to help with reconfiguring.

Hi, I have AL1716 so pretty the same - both cables (power and analog VGA cable) are inserted into sockets, probably your VGA cable can be screwed in - just unscrew it and go to nearest PC shop to buy new one. What a good cops you have !!
